- Space Experiment Instrument Developed by SKKU Research Team will be bound Internation Space Station
- Space Experiment Instrument Developed by SKKU Research Team will be bound Internation Space Station Space experiment instrument developed by Sungkyunkwan university research team will be bound for the International Space Station. Sungkyunkwan university announced a silicon charge detector(SCD) developed by research team of Prof. Ilheung PARK of department of physics will be delivered to the International Space Station on 15th, at 1:31 pm(Korea time) at the Kennedy Space Center in the United States. The space experiment instrument will be delivered to space by a SpaceX rocket ‘Dragon’. It will be installed on an outside module of the International Space Station and be expected to perform space mission for at least three years. The silicon charge detector is instrument to measure component of cosmic rays which is particles falling to Earth from space. It is made by using Semiconductor sensor technology. Cosmic rays is first detected in 1912, but its origins or spread processes have not been identified for more than 100 years. So, The Cosmic Ray Energetics And Mass mission destined for the International Space Station (ISS-CREAM) is designed to measure the highest-energy cosmic rays by National Aeronautics and Space Administration (NASA). The Republic of Korea, the United States, Mexico and France are participating in the experiment. According to Sungkyunkwan University, the silicon charge detector will play a key role in the ISS-CREAM. It is made of pure domestic technology and has an area of 1 ㎡ and a weight of 150 ㎏, which is the maximum size of a detector used in space. Four layers of silicon sensors measure component of cosmic rays. (Accuracy 99%) This detector was developed by Sungkyunkwan University in cooperation with Korea Electronics and Telecommunications Research Institute and small and medium enterprises, and Korea Institute of Industrial Technology did space environment experiment. The whole process was conducted in Korea. Prof. PARK said “This is the first time that domestic high-tech instrument is used in large space experiment of the International Space Station.”, and “This is a case we make the core instrument for main space project of NASA, and participate as main partner.” University College

- Taller People Are Thinner, a Study by Prof. Beom Jun KIM
- Taller People Are Thinner, a Study by Prof. Beom Jun KIM If the human body is stretched in three directions of width, length and height, the weight of a human body is proportional to the cube of its height. However, this is not valid in reality, and the body-mass index (BMI) is often calculated from the weight divided by the square of the height. From such definition of the BMI, Prof. Beom Jun KIM has shown that the waist circumference of a human is not proportional to the height, but proportional to the square root of the height. In other words, if the body-mass index is the same, the taller person is thinner. “This is the reason why many fashion models are tall,” Prof. KIM says. By analyzing the data of the length and weight of a variety of fishes, whales, and quadrupedal land mammals, Prof. KIM has shown that weight is proportional to the square of the height only for humans. In the case of other animals, the weight is proportional to the cube of the height. He presumed the reason why the calculation of the body-mass index of a human differs from that of other animals is that humans are bipedal, standing and walking upright. From this, he predicted that in the case of infants who cannot walk yet, their weight should be proportional to the cube of their height, but children older than about one year old should have a weight proportional to the square of their height. This prediction was tested for data from Sweden, Korea, and the World Health Organization, and was confirmed to be correct. If we consider the human body as the form of a simple cylinder and apply the condition that the torque by gravity and the torque by muscle must be in balance, we can show that the weight of a human should be proportional to the square of the height using Newtonian mechanics of physics. Prof. KIM also said that if we measure the size of the pelvis and the height from human fossil records, we will be able to deduce the time when mankind started to walk upright. Figure 1. Graphs of the relationship between the height (H) and the weight (M) of pale chub fish, whales and land mammals. All three graphs show that the animals’ weight is proportional to the cube (p = 3) of the height. For land animals, the height (H) can be measured in two ways: shoulder height and head-to-tail length. Both ways to measure the height meet the relationship (M is proportional to the cube of H). Figure 2. Graphs of the relationship between the height (H) and the weight (M) of children from Sweden and Korea. In this figure, the purple dots represent infants younger than one year old, and the orange dots represent children older than one year old. At one year of age, the time when a child begins to walk, the relationship between the height and weight is changed. Before one year, the weight is close to the cube of the height as with the other animals in Figure 1 above, but after one year, weight is close to the square of the height. Figure 3. A simple model of a human body. By applying the equilibrium condition of the torque by gravity (Fg) and the torque by muscle (Fm), we can show that the weight of a human being should be proportional to the square of the height. Figure 4. According to the body-mass index calculation method, the waist circumference of a human being is proportional to the square root of the height. The figure shows how body somatotype is changed according to the height if the body-mass index is the same. The taller the person is, the thinner it becomes. In the figure, when the height doubles, the waist circumference is about 1.4 times (or the square root of 2) smaller. Figure 5. Unlike a human body, when the length of a fish doubles, the height of the torso also doubles. In other words, it is difficult to know the actual fish size only from fish pictures without comparisons because both big fish and small fish look the same. This is because the weight (or volume) of the fish is proportional to the cube of its length. University College

- A wet-tolerant adhesive patch inspired by protuberances in suction cups of octopi
- A wet-tolerant adhesive patch inspired by protuberances in suction cups of octopi -Nature, Materials science: How to suck like an octopus- Adhesion strategies that rely on mechanical interlocking or molecular attractions between surfaces can suffer when coming into contact with liquids. Thus far, artificial wet and dry adhesives have included hierarchical mushroom-shaped or porous structures that allow suction or capillarity, supramolecular structures comprising nanoparticles, and chemistry-based attractants that use various protein polyelectrolytes. However, it is challenging to develop adhesives that are simple to make and also perform well- and repeatedly- under both wet and dry conditions, while avoiding non-chemical contamination on the adhered surfaces. Here Prof. Chang Hyun PANG and his team present an artificial, biologically inspired, reversible wet/dry adhesion system that is based on the dome-like protuberances found in the suction cups of octopi. To mimic the architecture of these protuberances, they use a simple, solution-based, air-trap technique that involves fabricating a patterned structure as a polymeric master, and using it to produce a reversed architecture, without any sophisticated chemical syntheses or surface modifications. The micrometre-scale domes in our artificial adhesive enhance the suction stress. This octopus-inspired system exhibits strong, reversible, highly repeatable adhesion to silicon wafers, glass, and rough skin surfaces under various conditions (dry, moist, under water and under oil). To demonstrate a potential application, they also used our adhesive to transport a large silicon wafer in air and under water without any resulting surface contamination. Their octopus-inspired adhesives might be useful when applied over skin or a wound and so partially assist with wound healing. They note that our patches promoted wound healing less well than did 3M Tegaderm, but they are investigating stem-cell and drug-loading approaches to improve their practical utility.

- PBS Introduces a Research by Prof. Young Han KIM
- PBS Introduces a Research by Prof. Young Han KIM SKKU Professor Young Han KIM’s research entitled “The Face of Risk: CEO’s Facial Masculinity and the Risk of the Firm” which was presented at the American Finance Association convention held in January of this year, was introduced at the TV Show “Making Sense” by PBS on May 25th. Public Broadcasting Service (PBS) is the most prominent provider of television programming to public television stations in the US, and it is categorized as one of the six major commercial broadcasting networks together with NBC, CBS, ABC, etc. “There is a strong link between facial masculinity and risk taking behavior,” said Prof. KIM who is now exploring the possible link between CEO risk taking and the male hormone testosterone. In the research, the ratio of facial width-to-Height Ration (fWHR), a sculpt measurement technique developed by archaeologist has been proposed as a proxy for masculinity according to the theory that it is influenced by exposure to testosterone. The hypothesis is that an individual is more masculine if they have a wider face. Also, Prof. KIM found out that the typical ratio of fWHR in men is 1.83, but the average score for 1,162 CEOs measured by neutral 3rd parties was significantly higher than 2.0. This presents evidence that if a CEO has a wider the face, they may have a higher correlation with risk taking which may lead to more mergers and acquisitions. Prof. KIM has also begun to study the relationship between the vocal pitch and testosterone; at any given age, the lower the pitch, the higher the testosterone. In the episode of the program, Prof. Jennifer Lerner’s (Harvard Kennedy School of Government) study on the “Influence that Masculinity Has on the Company Culture and Risk taking” was also aired.
