Accidents at construction sites in Korea account for more than half of all industrial accidents. To solve this problem, a policy to strengthen safety education was implemented to ensure the safety of workers. However, it was analyzed that there is a high possibility of accidents because workers did not receive proper safety information for each risk factor due to general lecture-style education. In addition, statistics show that the accident status of workers with fewer years of period is high, indicating that a customized information delivery method needs to be proposed for unskilled workers with fewer years of period. Research on the importance of education has been conducted, but no information delivery method has been identified. For unskilled workers to effectively receive safety information, appropriate delivery formats (text, photos, illustrations, 4D-BIM, 360-based panorama, video, animation) were analyzed, and a new method of education was proposed. If customized safety information is provided according to this proposal, effective information delivery to unskilled workers will be possible, and it is expected to be verified in various ways.

Purpose: This study's primary goal is to investigate and evaluate the critical contributions made by industrial-organizational psychologists to raising worker job satisfaction. The study aims to offer insights that can enhance workplace environments, improve organizational processes, and increase employees' general well-being by looking at the particular contributions made by this field. Research design, data and methodology: The study design, data collection strategies using the literature content analysis allow for a thorough analysis and synthesis of the body of knowledge about industrial-organizational psychologists' contributions to improving worker job satisfaction. This method entails a sequential procedure that includes formulating research questions and locating pertinent studies. Results: Numerous previous works have indicated that industrial-organizational psychologists are essential in determining how an organization is run and how satisfied its workforce is with their jobs. The four major roles (Job Design, Leadership, Workplace Culture, and Employee Development) that were found after a thorough analysis of the body of current literature are presented in this section. Conclusions: In sum, the roles found in this study provide organizations with a framework for creating work environments that prioritize the well-being and overall growth of the people who make up the organization while also helping them negotiate the complexity of the modern workplace.

Background: The purpose of this study is to investigate the relationship between job stress and impaired fasting glycemia (IFG) of male workers in a manufacturing industry. Methods: Data were collected from 5,886 male workers in a manufacturing industry who participated in the medical examination from June 19 to August 14, 2020 through self-reported questionnaires. The general characteristics of the subjects, shift work, high blood pressure, dyslipidemia, and job stress were included. Job stress was measured using the Korean Occupational Stress Scale (KOSS) consisting of 8 items and 43 questions. Multivariable logistic regression analysis was used to investigate the IFG association with job stress. Results: Among the various factors that can cause job stress, only high job demand was associated with a risk of IFG (odds ratio, 1.43; 95% confidence interval, 1.13-1.82) especially in non-shift worker. For all other factors, no statistically significant results were obtained. Conclusions: In this study of male workers engaged in the Korean steel manufacturing industry, the 'job demand' item among job stress of non-shift worker was related to IFG.

The purpose of this study is to assess the welfare level for shift workers by means of their satisfactions to the jobs in manufacturing environment. As a measurement tool of job satisfaction, we use the JDI(Job Descriptive Index) which can ensure reliability and are widely used. Measurement factors are investigated by means of the duty, payment, promotion, supervisor, co-workers, and general job satisfaction of shift workers. For the application of job satisfaction, 109 workers, 12-hour shift workers in domestic five companies related with manufacturing industry are considered. They treat general facilities in night shift work. The result of this study may be used as a strategic data of welfare policy for improving the welfare level of shift workers.

This paper examined the relationship between job stressor and job satisfaction according to the general property of disabled workers. Role ambiguity, role conflict, and role overload were cast as the factors of job satisfaction to explore their relationship with the general property and type of disabled workers. The results revealed that role ambiguity had the strongest meaningful relationships with job satisfaction and role conflict, role overload had not shown the meaningful relationships with their Job satisfaction. The reason of this results seemed to be from the fact that the work type available or not available to disabled worker was determined beforehand according to their disability type. Finally, these findings provide a guidelines of efficiency human resource management and strategic development program for the disabled workers.

Pilots are exposed to carcinogenic substances like radiation, ozone, exhaust gas from jet engine, and electromagnetic wave, their environment can be very hazardous. I designed this study to know if there is any difference between pilots and general people in cancer incidence. I analyzed cancer cases between 1999 and 2008, and investigated their age, site, aircraft types, and sex. I compared pilot's cancer incidence with general people during same periods. Statistical analysis was performed with standardized incidence ratio (SIR). 10 cases were high performance pilots, 5 cases were low performance pilots. The average age when the diagnosis had been made was $39{\pm}7.8$. Pilot's incidence ratio was lower than people's, the most common cancer was kidney, and there was no lung cancer. Cancer is influenced by gene and environment, each country has different patterns. The low incidence ratio in Korean pilots might be due to "healthy worker effect". I think we should perform further investigation on kidney cancer.

A study is for the approach that we could reduce the logistics costs through uprising the efficiency, complying to the demand in time, stock management based on the general production plan in the point of SCM. We will take following steps to get the goal. First, we will overview the physical distribution expenses annually. Second, will find the main cause of optimal load loss by improper container and lack of delivery flexibility to the demand. Third, the goal will be inferred through the fast information share based on organic relationship, the establishment of general production plan, the improvement of stock management plan. By way of this process, it can be accomplished expense reduction as well as flexible establishment of the reduction of worker's load.

As a general index in surface quality of machined products, surface roughness is to measure worker's skill level, a ground product quality and machining accuracy, etc. The surface roughness is defined by a function of rotational speed and radius of a grinding wheel, distances of active grains composed of the wheel, and feed of a grinder's worktable. To predict surface roughness in horizontal surface grinding operations, probability distributions were used. Probability distribution functions(p.d.f.) of surface roughness were found as results when the size of active grains(=the radius of a grinding wheel) is given as uniform, exponential distribution, and the distance between active grains follows the distributions of uniform, exponential. For each pdf case, probabilistic features of surface roughness were also analyzed and presented. This study is a substantial step for determining mathematically the surface roughness instead of using empirical approaches. More works should be presented to develop a general model by which an accurate roughness value can be obtained in horizontal surface grinding operations.

본 연구는 강원도 일부 고랭지 농업 농민을 대상으로 농약 노출 실태와 농약 노출로 인한 급성 중독 증상 경험을 비교하기 위하여 농약 노출력과 급성 중독증상에 대한 설문을 강원도 강릉시 왕산면 대기리의 고랭지 농업지역 농민을 대상으로 면접식 설문을 실시하였다. 연구결과 농약 노출과 농약 사용 기간은 두 집단간에 차이가 없었으나 연간 살충제 사용 일수는 고랭지 농업 농민이 1년에 평균 35.9일로 일반 농업 농민의 14.4일보다 더 많이 사용하였다. 일일 살충제 사용 시간도 고랭지 농업 농민이 하루 6.7시간으로 일반 농업 농민의 2.8시간 보다 길었다. 농약 노출에 의한 급성 중독 점수도 고랭지 농업 농민에서 유의하게 높았다. 회귀분석 결과 급성 중독 증상은 제초제 노출과는 통계적으로 유의한 상관성이 없었으며 살충제 노출과는 밀접한 연관관계가 있었다. 또한 중독 증상으로는 '피부가 따갑고 가렵다', '머리가 어지럽거나 아프다', '온 몸에 힘이 빠진다', '눈이 따갑다', '구역질이 난다' 의 5개 문항에 있어서 고랭지 농업 농민이 더 많이 경험을 하였으며 '눈 앞이 흐려졌다', '의식을 잃고 쓰러진다', '전신이 마비되었다'. '말이 나오지 않았다'의 4개 문항은 양 군간에 차이를 보이지 않았다. 증상의 경험률은 전체적으로 52.9%였으며 농업 형태별로 보면 일반 농업지역은 51.1%, 67.9%로 매우 높은 편이었다. 증상별로 보면 두통의 경우 전체적으로는 40.7%였으나 고랭지 농업의 경우는 73.7%, 일반 농업의 경우는 35.3%였으며 피부증상의 경우에는 전체적으로 22.9%, 고랭지 농업 농민은 57.9%, 일반 농업 농민은 17.2%였다. 이상의 연구결과를 볼 때, 고랭지 농업 농민은 일반 농업 농민보다 농약 노출이 많은 것을 알 수 있으며 추후 고랭지 농업 농민들의 농약 노출에 대한 건강영향 평가 및 농약 노출을 감소시켜 건강장해를 예방하기 위한 다양한 연구 및 행정적 노력이 필요할 것으로 사료된다.
