Purpose: Examine changes in the aspect and state of patient with infertility who admitted to Korean oriental hospital. Look at the changes in last 8 years and seek how oriental medicine can approach to infertility patients who admitted to Korean oriental hospital in last 8 years. Methods: Total of 7434 new patients with infertility who admitted to Gynecology of Oriental Hospital, $\bigcirc\bigcirc$ University Medical Center, from October 2002 to December 2009 was compared to infertility patients based on bottom collected data in this study, total of 1061 infertility patients were targeted for this study. Results: 1.There is no distinct increases in age between women who admitted to oriental medicine and patient's average age, it has shown constantly increasing trend in their age though. However, the average age of infertility patients have shown significant increasing range than average age of all infertility patients. 2. After analysis the result of infertility patient's rate of overall patients, the rate of infertility patients are remaining the same or slowing down in 2005, as the starting year(Table 2). The significant relationship was found in diagnosis and treatment of gynecology(Table 4~5) for infertility patients. In 2005 as the starting year, as patients who admitted to oriental hospital after diagnosed or treated at gynecology are increasing, the rate of infertility patients of overall patients admitted to hospital is slowing down, which is decreasing. 3. There is increasing number of patient diagnosed with "unknown cause" who admitted to Gynecology of Oriental Hospital after year of 2005. 4. The increasing number of patient diagnosed with "unknown cause" who admitted to oriental hospital has a tendency to be important factor in infertility treatment of oriental medicine. Conclusion: Unknown causes of infertility patients who admitted to oriental hospital will continuously increase as senses of society, economic, and social climate change.

Transportation systems around the world are difficult to maintain sustainability that, in a broad sense, is the capacity to endure. By connecting Entropy theory and systems thinking, we find the current problems and seek alternative plans. Distortions of the current transportation system to improve individual's ease and increasing traffic congestion, impose us the heavy energy consumption and will make increase whole entropy. UNEP reports are presented following three reasons that undermine the sustainabillity. The first one is that the prevalent traffic system highlight benefits of accessibility than benefits of mobility, the second, deteriorate excessive energy consumption, and the last reason is that personal vehicles has inhibited the use of public transportation. Alternative ideas to enhance the sustainable transportation system are these; (1) changeover from 'Ease of movement' to 'space efficiency', (2) evolving the smart traffic system instead of the construction or expansion of the road and (3) creating more comfortable the use of mass transportation. In addition, there are another ways that encouraging modal shift that increase traffic of goods, transport over railway lines and waterways, decongesting transport corridors and elevating technology to improve public transportation. The most importantly, we converse our cognitive process to be willing to enjoy uncomfortable and annoying life.

Physical manifestations of aging due to the lack of exercise include the slowing down of motor learning, cardiopulmonary degradation, and the increasing difficulty to adapt to the environment. Aging is manifested with the lack of aerobic exercise work, decrease in muscular endurance, decline in skeletal and muscular strength, flexibility and agility, and the decrease in reaction speed and balance. Added to those are aging-related physiological changes, including the reduction of muscle bulk, increased body fat, decrease in total body water and basic metabolic rate as activities are reduced, and a decrease in cell and Lean Body Mass (LBM). These changes are known to cause problems. Interest and participation in appropriate physical activities among the elderly is needed to help them increase stamina, avoid diseases, maintain a clear intellect, and basically enable the elderly to live their daily lives as easy as possible. Therefore, physical activities are necessary for the elderly to enhance health-related factors. Special exercises should be performed for the enhancement of muscle function, muscle endurance, flexibility, agility, and balance. An accurate measurement of cardio-respiratory endurance and stamina through basic physical and cognitive characteristics of older adults is also required to ensure safety. Also, the development of a more scientific resistance exercise prescription system for the elderly is desperately needed.

The Hanryu(韓流) phenomenon in and around Asia looks like slowing down lately. At that time, the research about contents that can inform the high traditional culture of Korea is useful. The references which can make a study about cultural clothes, especially paintings, let us to infer the life of the people of that period. In this research, I try to study the characteristics of customs, symbol and costumes by analyzing the paintings of Shin, Yun-Bok who was genre painter of the late Chosun. The mens are wearing dopo(道袍) and are putting sejodae(細條帶) around their waists and gat(黑笠). Also, We can see many different types of job such police, official man, a buddhist priest, a barmair, kisaeng and shaman through the costume. Most of women in the paintings, They are wearing Deep blue skirts, banhwoejang pale tone jeogori and tress. We discussed the common lives of the people through genre painting. They have satire, humor, and symbolism. Also, we can look into the various lifestyles, customs of times and seasons, ceremonial occasions, civilian beliefs, and plays ransmitted from the past. The philosophy in Shin, Yun- Bok's genre painting, is close to Taoism not Confucianism.

The neutron capture cross section of $^{99}Tc$ has been measured relative to the $^{10}B$(n,g) standard cross section by the neutron time-of-flight(TOF) method in the energy range of 0.007 eV to 47keV using a 46-MeV electron linear accelerator(linac) at the Research Reactor Institute, Kyoto University(KURRI). In order to experimentally prove the result obtained, the supplementary cross section measurement has been made from 0.3 eV to 1 keV using the Kyoto University Lead slowing-down Spectrometer(KULS) coupling to the linac. The relative measurement by the TOF method has been normalized to the reference value(20.01 b) at 0.0253 eV and the KULS measurement to that by the TOF method. The existing experimental data and the evaluated capture cross sections in ENDF/B-VI, JENDL-3.2, and JEF-2.2 have been compared with the current measurements by the linac TOF and the KULS experiments. The energy dependency of the KULS data is close to that of the TOF data which are energy-broadened by the resolution function of the KULS.

In this study the mechanical properties of ferritic ductile cast iron in as-cast are discussed by metallographic considering the effect of phosphorus content(about 0 - 0.8wt.%). In ferritic S.G. cast iron containing about 4.2wt.% Si, 0.5wt.% Ni, 0.02wt.%B, these samples are investigated for castability, microstructure, machinability, wear resistance, mechanical and thermal properties. The main results are summarized as follows. 1) The chill depth increased greatly with P addition up to about 0.6wt.% but the tensile strength and the elongation are decreased smoothly. 2) The size of S.G. and the amount of steadite increase with increasing P content. This means the tendency of increasing the number of S.G. 3) The maximum value of wear by mechanical fracture was appeared at the abrasion speed of 1.14m/sec and the plastic Flow layers are stretched longly on the wear surface with decreasing P content. 4) Although the coefficient of thermal expansion increased with P addition, the cast iron growth was slowing down extremely at 0.6w.% P or more.

A Slowing Down Time Spectrometer (SDTS) system is a highly efficient technique for isotopic nuclear material content analysis. SDTS technology has been used to analyze spent nuclear fuel and the pyro-processing of spent fuel. SDTS requires an external neutron source to induce the isotopic fissile fission. A high intensity neutron source is required to ensure a high for a good fissile fission. The electron linear accelerator system was selected to generate proper source neutrons efficiently. As a first step, the electron generator of an 80-keV electron gun was manufactured. In order to produce the high beam power from electron linear accelerator, a proper beam current is required form the electron generator. In this study, the beam current was measured by evaluating the performance of the electron generator. The beam current was determined by five parameters: high voltage at the electron gun, cathode voltage, pulse width, pulse amplitude, and bias voltage at the grid. From the experimental results under optimal conditions, the high voltage was determined to be 80 kV, the pulse width was 500 ns, and the cathode voltage was from 4.2 V to 4.6 V. The beam current was measured as 1.9 A at maximum. These results satisfy the beam current required for the operation of an electron linear accelerator.

Purpose Wearable device is considered as one of the methods powering the growth of the next generation. However, ICT's innovation resistance has been a contributing factor in slowing down this spread of wearable devices. Taking into consideration the lack of empirical research to this phenomenon, this study served to examine the effect of determinants of wearable devices to usage with the perspectives of behavioral economics. Design/methodology/approach: For research purposes, this study developed research hypotheses in order to empirically examine the factors that might have a significant effect on the usage of the wearable device. The empirical research was based on a survey which carried through 500 participants. Research results were evaluated via SPSS Statistics 21.0 and AMOS 19 statistical package program. Findings: Results showed that perceived costs and benefits had a significant effect on coupling. It means that perceived benefits lowering coupling and perceived costs increasing coupling. Perceived costs and benefits also had a significant effect on innovation resistance. Finally, perceived costs and benefits had a significant effect on the consumers' usage of wearable devices.
