Glasses industry has great growth potential from the future-oriented perspective in Korea. In consideration of the fact that the ratio of aging population increases in this aging society, people have more and more interest in health. Also, their recognition on the cycle to change glasses is changing, and the utility of them as fashion items is increasing day by day, it is expected that the demand for glasses will be even more extended afterwards. Of course, presently it suffers from the gap between cheaper items and expensive ones provided by overseas prominent brands due to the bi-polarization of the market. However, they are pursuing the 2nd growth as export-leading items in the past through international glass exhibitions based on knowhow accumulated for a long time. Therefore, this study aims to examine the current status of glasses design industry in Korea reflecting the actual situations we have now and also understand the problems and limitations internalized in our glass design industry through the research process. As a result, the study has drawn the following conclusions. This paper intends to point out first, the phenomenon of bi-polarization of the glass market in Korea. Second, unequal distribution by region centering around Daegu. Third, the limitations of brand identity. Fourth, the limitations of information, planning, and marketing power. Fifth, passive conduction of international events and their insufficient effects. This study concludes that all these problems can be solved through 'planning and design, and marketing power'.

This study tries to understand the characteristics of a man's clothes from the late 17th century to the early 18th century, held by the Ewha Womans University Museum. The author adopted the Assy CAD, an apparel CAD system developed by Assysit Company of Germany, in measuring clothes which is intended to solve the problems raised in the previous measurement of clothes, as well as in the making of patterns. The author used tracing paper to make copies of the curved parts, put them into the computer by digitiger, and made the patterns for more accurate restoration. Furthermore, the author compared Lee Hwang's with the contents of the related literature and excavated apparel from other tombs. As a result, Chopri among Lee Hwang's clothes, retained the typical characteristics of the mid-Chosun men's fashion in its ratio of bodice to skirt, form of sleeves, and size of breast- ties for fastening which appeared in the 17th century. Daechangeui and Jungchimak also were distinctive for Changot and the width of sleeves since the 17th century and were in wide use not only as the daily clothes but also as the shroud. These changes were brought about from the two wars which emphasized prestige and beauty of the clothes rather than their functions. As a result, Changeuis were used more widely, while Chopri which was used as the underwear of officials' uniform, was in decline.

The main goal of this study is to investigate the hysteretic behavior of polyurethane rubber springs in compression with and without precompression. The precompression is introduced to provide rigid force in the behavior, and thereby a precompressed rubber spring can be used for a restoring element. For the goal, this study prepares nine rubber springs for three suites which are all cylindrical in shape with a hole at the center. The rubber springs in each suite have different dimensions of diameter and length but have similar shape factors; thus, they are designed to have a similar compressive stiffness. Three rubber springs from the nine are tested with increasing compressive strain up to 30% strain to investigate the behavior of the rubber springs without precompression as well as the effect of the loading strain. The nine springs are compressed up to 30% strain with increasing precompressive strain from 0 to 20% at increments of 5%. The study analyzes the effective stiffness and damping ratio of the rubber springs with and without precompression, and the rigid force of the precompressed rubber springs is discussed. Finally, this study suggests a regression method to determine the minimum required precompression to eliminate residual strain after unloading.

Eight hundred thousand asteroids in the solar system have been identified so far under extensive sky surveys. Kilometer to sub-km sized asteroids, however, are still waiting for discovery, and their size and orbital distribution will provide a better understanding of the collisional and dynamical evolution of the solar system. In order to study the number of asteroids which is detectable with 1.6 m telescope and their orbital distribution, we conducted a small observation campaign as a part of Deep Ecliptic Patrol of the Southern Sky (DEEP-South) project, which is an asteroid survey in the southern hemisphere with Korea Microlensing Telescope Network (KMTNet). We observed the ecliptic plane near opposition ($2^{\circ}{\times}2^{\circ}$ field of view centering on ${\alpha}=22h40m31s$, ${\delta}=-08^{\circ}22^{\prime}58^{{\prime}{\prime}}$) in August 2018, and identified 464 moving objects by visual inspection. As a result, 266 of 464 moving objects turn out to be previously unknown asteroids, and their signal to noise ratio is below two on numerous occasions. Most of the newly detected objects are main belt asteroids (MBAs), while three Hildas, one Jupiter trojan, and two Hungarias are also identified. In this meeting, we report the differences in the orbital distributions between the previously known asteroids and newly discovered ones using statistical methods. We also talk about the observational bias of this survey and suggest future works.

This study analyzed the relationship between elderly suicide rates and socio-economic factors from the macroscopic perspectives. As certain theoretical background of elderly suicide, sociological and economic perspectives are applied. The economic factors of elderly suicide rates consisted of economic growth and unemployment rate, economic activity rate of the aged, and relative poverty rate (income inequality rate). The sociological factors included social welfare spending, divorce rate, growth rate of population aging, and elderly dependency ratio. According to research findings, first, the more economic activity of the aged is low, the more elderly suicide rate is high. Second, the more social welfare spending rate goes flat, the more elderly suicide rate is growing. Third, the more relative poverty rate (income inequality), increasing population aging rate, and elderly dependency ratio are high, elderly suicide rate goes high at the same time. Finally, this study proposed several socio-economic policy alternatives for preventing continuous growth of Korean elderly suicide rate.

Purpose : Centering on users(patients) who are offered the patient transport service by the emergency medical service system in our country, the use and satisfaction are analyzed with the transport service in 119 Emergency Medical Service System and Private transport agent. Results : 1. As for personnel in ambulance cars, 119 emergency staff showed a higher boarding rate of the first-class emergency medical technicians than private transportation centers : 48.4% and 17.7%, respectively. 2. Private transportation centers showed higher user satisfaction with transportation service than 119 emergency staff, which was not statistically significant. 3. As for the case that needs to receive the transport service in the future, the ratio with the will to use 119 Emergency Medical Service System(70.9%) was indicated to be much higher than the ratio of the private transport agent(29.1%). Suggestions : First, Centers transporting first-aid patients should essentially secure a sufficient number of first-class emergency medical technicians as professional emergency medical staff to reinforce qualitative improvement in emergency medical service. Second, It is necessary to establish a systematic monitoring system and develop educational programs in order to enhance satisfaction with the use of 119 emergency staff. Third, the government or the local government needs to positively support and guide the private transport agent, which is in charge of the public medical service.
