As advances in artificial intelligence (AI) increasingly approach areas once relegated to the realm of science fiction, there is growing public interest in using these technologies for practical everyday tasks in both the home and the workplace. This paper explores the applications of and implications for of using ChatGPT, a conversational AI model based on GPT-3.5 and GPT-4.0, in the field of occupational health and safety. After gaining over one million users within five days of its launch, ChatGPT has shown promise in addressing issues ranging from emergency response to chemical exposure to recommending personal protective equipment. However, despite its potential usefulness, the integration of AI into scientific work and professional settings raises several concerns. These concerns include the ethical dimensions of recognizing AI as a co-author in academic publications, the limitations and biases inherent in the data used to train these models, legal responsibilities in professional contexts, and potential shifts in employment following technological advances. This paper aims to provide a comprehensive overview of these issues and to contribute to the ongoing dialogue on the responsible use of AI in occupational health and safety.

This study was focused on figure out what kinds of elements are influencing on job satisfaction with approach of the educational system. It was also to figure out how work characteristics and role conflicts of employees influence on job satisfaction. Objects of study were employeeswho had been working in Hospice and Palliative medical center at least for 6 months, and they were doctors, nurses, ministers, and welfare workers. Collected materials were analyzed by Frequency Analysis, One-way ANOVA, Correlation Analysis, and SimpleRegression Analysis. Results from study can be summarized like below. The first, job satisfaction of workers in Hospice and Palliative medical center were 3.36, and this numerical value is pretty high over all. For saying from the higher to the lower satisfaction level, there were satisfaction with job itself, satisfaction with co-workers, satisfaction with seniors (superiors), and satisfaction with organizations, on the other hands, satisfaction with salaries was turned out as the lowest level among those. The second, role conflict was 2.63, and it is considered as the medium level. after inquiring into it by elements of role conflict, they felt many environmental difficulties compared to other workers in different fields such as environmental difficulty, role ambiguity, insufficient ability, process obscurity, etc. The third, work environment influencing on job satisfaction are as follows. Professional environment among characteristics of work environment was significant statistically. Job satisfaction of ministers was the highest; others were in the order of doctors, welfare workers, and nurses. For employment history, job satisfaction was higher as they have more and longer job experience including whole professional experience both in hospice and palliative medical center. In addition, participating in hospice and palliative programs, intensive training regularly was significantly. Job Motivation was also significant statistically. Especially, job satisfaction was higher when people decided to work in hospice and palliative medical center because of individual desire (self-realization). Lastly, influence of role conflict on job satisfaction is as follows. Environmental difficulty, role ambiguity, insufficient ability, process obscurity, etc showed the significant meaning statistically, and the lower role conflict was related with the higher job satisfaction. Suggestions for next study based on such results are as follows in order to improve or increase job satisfaction of employees in hospice/palliative medical centers. The first, to expand education opportunity of employees is needed to increase job satisfactionof hospice/palliatives medical centers. Participating in intensive programs and seminars by types of occupation and acquiring professional knowledge are very important since employees are motivated by those activities. For that, developing and activating intensive education/programs by professional occupations are suggested. The second, dividing roles of employees and determining each job's limit clearly in hospice/palliative medical centers are required. For that, study developing standard job regulations is suggested for each professional job. Lastly, developing and providing reasonable salaries is needed because low salaries of hospice/palliative medical centers are the absolute reason lowering job satisfaction. Therefore, this paper suggests improving the salary level of employees of hospice/palliative medical centers and developing practical plan for it.

The purpose of this study is to provide the planning factors of housing for the disabled and elderly based on the inclusive housing design as sustainable neighborhood. The goal of inclusive design is to make buildings and communities more livable for all type of people. Inclusive design should embrace other good design goals and reinforce them, not work against them. To carry out this purpose, we should proceed in the following way: First, we deducted the four design factors (the basic, recommendable, adaptable, and residential factors) by reviewing the characteristics of inclusive housing concepts. Second, we analyzed the related foreign design standards and guidelines such as the ICC/ANSI A117.1 Type C Units (the United States, 2009), Lifetime Standard (the United Kingdom, 2010), and Livable Housing Design Guideline (the Australian, 2010) through four design factors based on inclusive design concepts. Finally, we suggested the housing design factors for the disabled and the elderly in Korea. To conclude, we can make the followings: It is important basic factor that the bedroom and bathroom layout closed to each other. Also, the bedroom has the proper height of light switches, outlets, and windows. The recommendable factors take into consideration stairs and ramp, if existent. The adaptable factors are closely related to domestic housing culture as well as residential factors. Proceeding from this fact, the livability for people with disabilities and older requires accessibility and adaptability that take into account public and efficiency considering the current trend of housing development and urban planning.

오늘날의 모든 통신은 IP(Internet Protocol)을 기반으로 통합 및 연계되어 발전하고 있으며, IP를 통하여 사용자에게 '언제, 어디서나, 끊김 없는 서비스'를 제공할 수 있게 하기 위하여 많은 연구들이 이루어지고 있다. IETF에서는 IPv6를 사용하여 이동성을 제공하는 MIPv6를 제안하였으나 이동노드가 네트워크를 이동할 때 마다 HA(Home Agent)와 CN(Correspondent Node)에게 BU(Binding Update) 메시지를 보냄으로써 많은 Overhead와 전송지연이 발생한다. 이에 현재 MAP(Mobility Anchor Pointer)를 사용하여 CN에게 아무런 영향을 끼치지 않으면서 이동노드가 매번 핸드오버마다 발생하는 HA와 CN에게의 BU를 통한 지연과 Overhead를 줄일 수 있는 HMIPv6를 개발하였다. HMIPv6는 이동노드가 MAP 내부에서 핸드오버시, 같은 RCoA(Regional Care of Address)를 가지고 있음으로 BU를 HA와 CN에게 전달하지 않고 MAP가 직접 처리하여 MAP 내부에서의 이동에 관하여 전송지연과 Overhead 문제를 해결하였지만, MAP와 MAP간의 Macro 핸드오버를 효율적으로 수행하지 못한다. 본 논문은 HMIPv6환경에서 MAP간의 Macro 핸드오버시, 이동노드의 위치정보를 이용한 핸드오버를 사용함으로써 효율을 높일 수 있는 방안을 제시한다.

Lipid peroxidation induces functional deterioration of cell membrane and induces cell death in extreme cases. These phenomena are known to be related generally to the change of physical properties of lipid membrane such as decreased lipid order or increased water penetration. Even though the electric property of lipid membrane is important, there has been no report about the change of electric properties after lipid peroxidation. Herein, we demonstrate the molecular energy band change in red blood cell membrane through peroxidation by air-based atmospheric pressure DBD plasma treatment. Ion-induced secondary electron emission coefficient (${\gamma}$ value) was measured by using home-made gamma-focused ion beam (${\gamma}$-FIB) system and electron energy band was calculated based on the quantum mechanical Auger neutralization theory. The oxidized lipids showed higher gamma values and lower electron work functions, which implies the change of surface charging or electrical conductance. This result suggests that modified electrical properties should play a role in cell signaling under oxidative stress.

In 1937, most Korean compatriot who lived in Yunhaeju moved to Kazakhstan and Uzbekistan in Central Asia following the deportation policy of Russia. Korean compatriot have kept their traditional life style for 140 years, without a deep relationship with Korea. This study examined the heating systems of Korean compatriot in Yunhaeju, Kazakhstan and Uzbekistan, Russia. A literature review and field research, based on Ethnography as a research method, was employed. The results of the research were as following: 1) Korean compatriot in Yunhaeju use a Pechika, which is a radiator that uses hot water, and a Gudul as the main heating systems, but the use of a Pechika was most common. A Pechika functions for cooking as well as for warming the house. The room with the Gudul was connected to the kitchen, so this space was used as a place for cooking and eating, for family members to meet. Many kinds of fuel, like gas and electricity, were used to power the heating systems. 2) Korean compatriot in Kazakhstan use radiators, with hot water as the main heating system, with ratio using Gudul used in this region being the highest of all the three areas. The most common fuels used for a Gudul were wood and coal, and gas was also used in cooking. The room with the Gudul was planned to be located beside the fireplace, without any walls. The people using a Gudul use that place for eating and meeting, as well as for family members to sleep. 3) The main heating system of Korean compatriot in Uzbekistan was a radiator using hot water, and those with pipes containing hot water buried under the floor were very common. The function is very similar to that of a Gudul, so most people using this type of radiator would sleep on the floor. Those people with a traditional Gudul not using them were mostly in Uzbekistan. The reason for this was that the family members had diminished, so it was hard work for elderly parents to manage an extra building containing a Gudul. Gas was the fuel generally used for heating and cooking in Uzbekistan. 4) Guduls were used in the Korean compatriot's houses in all three areas, even though they have changed in structure to adapt to the Russian life style. However, Guduls have still been functioning to maintain a traditional life style in Korean compatriot's houses for the gathering of family members.
