After the rapid growth of economics in South Korea 1960'1, the number of workers in the whole land in-creased day after day along with the growth of industry. As the growth of the third industry occurred quite rapid-ly, the rate of office workers went up high. Accordingly the business office has been changed the primary work-ing space and recognized the main space as much as the living space. As a result of conceptual change about working place, the business office has an important ef-fect on worker's liberal and psychological environment. In order to provide the office workers with the office work-ers with the suitable and convenient working environ-ment, Socio-psychological factors were first considered at the first stage of construction planning. In this paper, I would understand both how office workers take up their attitudes of Socio-psychological point according to the office type and what they claim for their office environment. This understanding offers us fundamental data in office plan. This paper starting from this purpose got the following conclusions. *Office workers are violated their hearing privacies rather than their visual privacies. They are dissatisfied with ensuring their own spaces and satisfied with their nature of domain. *In the feeling of satisfaction by office type, they are on the whole satisfied with their hearing privacies, their visual privacies, their own space, and the nature of do-main in the closed type and mixed type offices. In open type offices, their visual privacy is often violated. *In the property by individual, men feel more violated their hearing privacies than women. In the personal spa-se and domain, women are less stabilized psycholo-gically than men. *The analysis of the attitude by position, a man of po-sition is more violated his hearing privacy and does not understand each other. The common run of workers are violated their visual privacies and the nature of separa-tion.

Purpose: The clinical syndrome of unilateral finger ischemia, caused by digital artery occlusions from embolization from the palmar ulnar artery associated with repetitive striking of the palm, has been called the hypothenar hammer syndrome (HHS). We report the case of a man with this unique disease probably caused by manual work. Methods: A 52 - year - old male left - hand dominant manual worker complained of pain and coldness in the left 4,5th finger. On physical examination, there was a tip necrosis and the result of Allen's test was mildly positive(sluggish filling of hand from the ulnar artery). Arteriograms confirmed occlusion of the distal ulnar artery without direct perfusion of the superficial palmar arch and distal digital artery. Surgical bypass with reverse autologous vein grafting was performed between ulnar artery and superficial palmar arch, common digital artery. Results: He had an uneventful postoperative course and has remained asymptomatic for 18 months since discharge. Patency has been confirmed by color doppler with resolution of cold intolerance and successful digital preservation. Conclusion: We introduce very unique pattern of vascular ischemic disease and recommend the arterial bypass with vein interpositional grafting.

This study was undertaken to determine the concentrations of airborne bacteria, fungi, particles, and endotoxin in swine and chicken houses. Six swine buildings and seven chicken houses were randomly selected in southern Gyonggi Province, South Korea. The geometric mean concentrations of airborne bacteria in swine and chicken houses were $2.7{\times}10^5\;CFU/m^3$ and $5.6{\times}10^7\;CFU/m^3$, respectively. The airborne bacteria concentrations in chicken houses were significantly higher than those of swine houses (p<0.05). The geometric mean concentration of airborne fungi in swine houses was $4.9{\times}10^3\;CFU/m^3$, which was higher than the value of $2.1{\times}10^3\;CFU/m^3$ found in chicken houses. The mean concentrations of airborne particles and endotoxin in swine houses were $3.48\;mg/m^3$ and $943.1\;EU/m^3$, and they were $15.43\;mg/m^3$ and $1,430.5\;EU/m^3$ in chicken houses, respectively. A significant difference between swine and chicken houses was found for total dust (p<0.05), but not for endotoxin. In this study, the concentrations of endotoxin in both swine and chicken houses as well as particles in chicken houses were high, and in about 50% of the samples exceeded the worker health safety levels of $614\;EU/m^3$ suggested in previous studies. These results may indicate a considerable respiratory hazard for workers in these environments.

3-D templates are produced to evaluate completeness of the shell plates during the forming process, which is an essential step for the ship production. They are mostly produced in advance during the detail/production design stage, but occasionally they are requested by the shell plate forming department, because it is impossible to predict accurately the necessities of them at the design stage. This results in a huge loss of man-hour and a bottleneck. In order to resolve this issue while reducing the dependence on other department, the process of manufacturing the 3-D templates needs to be automated. Therefore, this study proposes an automatic system that calculates the manufacturing information of the 3-D templates with only geometric information of the shell plates. The system considers the thickness and the cutting method of the parts of the 3-D templates and some options are provided to reflect the intention of the worker.

Objectives: The organizational culture of small-scale enterprises is influenced by a lack of awareness of industrial accidents and a business-oriented culture. Therefore, the purpose of this study is to establish a correlation between chemical awareness and worker safety, which is the reason why a company's safety environment is responsible for human factor accidents. Methods: The research model established the organizational culture, human relationships, organizational relationships, workplace culture, safety climate, and safety parameters, all of which affect the perception of chemical substances, then established safety rankings, communication, safety regulations, and safety support. Results: In order to derive the results of this study, the satisfaction level was mostly derived from the degree of engagement (+) depending on the number of years worked, in the hierarchical regression analysis. During work with chemicals, the number of years spent on the level of the service was determined by the influence of the chemical (-). Based on this company, the occurrence of chemical accidents caused by chemical materials was felt to be felt at the risk of causing the hazard to be felt, the absence of physical damage was excluded from the variables. The other variables detected in the variables were $62.8{\pm}24.4$. Conclusion: As a result, it is necessary to develop a statistical model for the verification of the hierarchical regression analysis, and the relationship between safety and awareness of the dangers of chemicals and biological agents requires periodic safety training. Job satisfaction was found to be higher if the level of awareness was sufficient.

콘크리트 표면절삭 작업은 콘크리트 표면의 평탄성 및 부착성을 필요로 하는 공사에서 빈번히 사용되고 있으나 작업형태가 노동집약적이며, 유해한 작업환경을 보유하고 있다. 또한 장비를 다루는 기능공의 숙련도에 따라 생산성 및 절삭품질의 편차가 큰 경향이 있다. 그러므로 주변 환경오염 방지와 장비 조종자가 위험에 노출되지 않도록 하기 위한 원격조종 콘크리트 표면절삭 장비 개발이 요구된다. 그러나 원격 조종 시스템에서 조종자가 절삭면의 품질을 측정하기 난해하고 품질에 대한 객관적인 판단을 내리기가 어려우므로, 본 연구에서는 머신비젼시스템(Machine Vision System)을 적용하여 네트워크 카메라로 촬영한 절삭면의 이미지를 디지털 영상처리(Image Processing)과정을 거쳐 그 결과를 그래픽 MMI(Man-Machine Interface) 프로그램에 표현함으로써 품질관리 시스템을 구축하였다. 머신비전 알고리즘은 콘크리트 절삭면의 디지털 영상처리 알고리즘을 의미하며 본 논문에서 제안된 알고리즘을 적용하여 콘크리트 절삭면의 객관적인 품질관리 기준을 제시하고자 한다.
