Facial recognition is a biometric technology that is used in various fields such as user authentication and identification of human characteristics. Face recognition applications are practically used in various fields, but very few applications have been developed to improve the factory work environment. We implemented applications that uses face recognition to identify a specific employee in a factory .work environment and provide customized information for each employee. Factory workers need documents describing the work in order to do their assigned work. Factory managers can use our application to register documents needed for each worker, and workers can view the documents assigned to them. Each worker is identified using face recognition, and by tracking the worker's face during work, it is possible to know that the worker is in the workplace. In addition, as a mobile app for workers is provided, workers can view the contents using a tablet, and we have defined a simple communication protocol to exchange information between our applications. We demonstrated the applications in a factory work environment and found several improvements were required for practical use. We expect these results can be used to improve factory work environments.

The present work is concerned with the switching conduction characteristics of PI LB films in metal insulator metal sandwiches. By applying various DC voltage bias to MIM junctions, conduction characteristics of junctions can be changed between the high-voltage low-current(off) condition, the low-voltage high-current (on) condition and the medium(mid) condition. Switching conduction characteristics can be also observed in MIM junctions employing some aromatic compounds as insulators. Switching conduction characteristics is assumed to be owing to the existence of aromatic rings, space charge in films, impurities on metal-insulator interface, and difference in work functions of base and top electrodes metal. To study the conduction process of on, off, and mid conductions, we measured I-V, d$^{2}$V/d I$^{2}$-V characteristics of junctions with several different top electrodes under various temperatures. Small conductance changes of junctions can be measured by observing the second derivative, d$^{2}$V/dI$^{2}$, of I-V curve. A dynamical technique is used to get the second derivatives. That is, a finite modulation of the current is applied to the junctions and the second harmonic of the voltage is detected.

최근 도심지 공사에 있어서는 공간부족 및 주변환경의 영향으로 기성파일의 시공이 불가능한 경우가 많다. 이러한 경우에 소형 장비로 시공이 가능하고 기존 파일의 지지능력을 발휘할 수 있는 소구경 파일 공법이 많이 사용되고 있다. 소구경 파일공법은 현장타설말뚝의 한 종류로서 파일의 직경이 75mm~300mm인 정도로 주변 구조물이나 지반 그리고 공간적인 장애물이 있는 경우에도 시공의 어려움이 거의 없으며 모든 종류의 토질조건에서 시공이 가능하다. 또한 시공과정에서 진동과 소음이 적고 건물 천장이 낮은 곳에서도 시공이 가능하므로 기존 건물의 기초보강에도 많이 이용된다. 이러한 마이크로파일이 압축력이나 인장력을 받았을 때 혹은 시공된 지반특성에 따라 변화되는 거동 특성에 대해서는 연구가 많지 않은 실정이다. 따라서 이 연구에서는 현장에 시공된 마이크로파일에 대한 현장재하시험 자료 분석을 통하여 마이크로 파일에 압축력 및 인장력을 가했을 경우 지반을 구성하는 성분과 파일의 근입조건에 따른 침하 및 지지력 특성을 규명하고 통계분석프로그램인 SAS를 활용하여 마이크로파일의 침하와 지지력에 영향을 미치는 주요한 인자에 대한 분석을 수행하였다.

The aim of this study was to evaluate the musculo-skeletal symptomatic features of municipal sanitation workers and to compare differences of the musculo-skeletal symptoms by work types. We conducted descriptive cross-sectional survey concerning the musculo-skeletal symptomatic features of 315 street cleaners in Seoul and GyeongGi Province, Korea, during 2 weeks of September 2006. Questionnaires were consisted of general characteristics, occupational characteristics and musculo-skeletal symptoms. And we observed their works and evaluated their movement and posture by REBA. For work types, tools and subjective physical work loading, there were statistical difference whether or not NIOSH symptom positive on upper limb. Musculo-skeletal symptoms on upper limb were claimed from 43.2% of street cleaners, more than in 32.4% of cleaners. Musculo-skeletal symptoms on upper limb were reported higher in the group who felt their subjective physical work loading severe than in the otherwise group. The REBA results were over 'high risk stage' in street cleaners. Street cleaners had more repetitive motions than solid waste collectors on upper limbs. Works according to the criteria of musculoskeletal burdened work by the Ministry of Labor results were over 'high risk stage' of No. 2 and No. 4 in street cleaners. We found that street cleaners complained musculo-skeletal symptoms on upper limb more than solid waste collectors. This study suggests that it is necessary for street cleaners to carry out the prevention program of musculo-skeletal diseases. For street cleaner, the measure plans such as job rotation, automatic street sweepers, reducing work hours are helpful in preventing musculoskeletal symptoms on the upper limb.

The purpose of this research was to find out attitudes toward work and leisure in later life and intention to move to senior community available to work among 50's in Pusan, Daegu, and Daejeon. The survey had been conducted in 414 respondents with questionnaire during May to June, 2003. Frequency, Crosstabs, T-test and ANOVA were obtained from the collected data using SPSS/WIN program. The results of this study were as follows. First, most respondents were preparing toward work in later life somewhat actively and the level of preparation differed by individual characteristics. Those who have higher level of education and subjective economic power were more active. The most preferred work item in later life were raising animals and plants, managing institution and training center and running shop. Those who have higher level of education and asset preferred managing institution and training center. Second, nearly three fourths of middle-aged have chosen leisure activities in consideration of later life and two thirds were preparing economically for leisure in later life. They have strong intention to participate in the leisure activity in later life and they also wanted to take part in various kinds of leisure activities. Those who have higher levels of education, subjective economic power, health and asset were more active in preparing leisure in later life. Third, over two thirds preferred to live and work in later life together with others rather than to live and work alone. Nearly half had intention to move to the senior community where work was available. The intention to move were differed by attitudes to work and leisure in later life. Those who were active in work and leisure in later life presented higher intention to move to senior community available work.

이 글은 영국의 시간제 근로의 특징과 그 제도적 맥락을 분석하고 있다. 노동시장에 대한 규제와 여성의 노동시장 참여에 대한 지원이 낮은 영국에서는 시장주도의 시간제 활용이 일찍부터 발달했다. 시간제 근로는 영국 취업 여성의 40 퍼센트를 차지할 정도로 특히 기혼 여성들의 주요한 일자리이다. 시장의 역할과 개인의 선택이 강조되는 영국에서 시간제 일자리는 고용주 주도의 시장의 유연성에 기여하는 방식으로, 그리고 여성들이 일과 가족 사이에서 시간제 근로를 통해 여성들 자신의 노동시간을 조정하는 주요 수단으로서 작동했다. 그러나 1997년 이후 영국에서는 제도적 개입을 강화하는 변화가 있었고, 시간제 근로를 기혼 여성을 위한 제한적 일자리로부터 보편적 유연근로로 변화시키려는 법적, 제도적 노력이 있었다. 이러한 변화는 시간제 근로에 대한 불이익은 원칙적으로 시정할 수 있게 되었으나, 여전히 이해당사자들 사이의 집합적 해결방식보다는 개별 근로자와 고용주 사이의 개인화된 해결방식으로 영국이 접근함으로써 여성들의 고용패턴, 그리고 시간제 근로의 질적 성격에 큰 변화는 나타나지 않았다.

PURPOSE: This study aimed to investigate the effect of empowerment on job satisfaction for physical therapists in general hospitals. METHODS: A total of 297 physical therapists working in general hospitals throughout the country participated in the study survey using self-administered questionnaires. The questionnaires comprised three major parts, i.e., questions about general characteristics, empowerment, and job satisfaction, which were rated using a 5-point Likert scale. Statistical analysis was performed to analyze the frequency and percentage of participants, and the independent t-test and analysis of variance were performed to determine the difference in job satisfaction according to the general characteristics. Stepwise multiple regression was used to evaluate the factors that affect job satisfaction. RESULTS: The average of total empowerment, including two subordinate concepts, was 3.29 points, that of psychological empowerment was 3.53 points, and that of structural empowerment was 3.05 points. The average job satisfaction of the participants was 3.43 points, and it showed a significant difference in age, overall work experience, current work experience, position, annual salary, and daily work hours. Moreover, job satisfaction increased as the subordinate factors for empowerment, i.e., support, resources, chance, and competence, increased. Other factors that affect job satisfaction were daily work hours, number of colleagues, type of work, annual salary, and therapeutic assistance. CONCLUSION: This study demonstrated that job satisfaction of physical therapists working in general hospitals was related to empowerment, thereby indicating that job satisfaction and work performance can be increased by improving their empowerment.

Though there might exist not a few differences between cyclic works and atypical works, many researchers have applied the same assessment techniques that used for repetitive works, which may result introduce bias in their conclusions. This research aimed to verify whether there exist non-negligible work characteristics and/or dissimilarity among works with different work nature and whether one of the most prevalent assessment techniques for assessing ergonomic hazards of musculoskeletal disorders, REBA, can be applied to atypical works. For a general hospital, an automobile repair shop, and two auto-part assembly plants which manufactures quite different parts, a questionnaire survey and field investigation and ergonomic assessment were carried out and analyzed statistically with reference to the 3rd Quantification technique. The results showed that there exist remarkable difference between physical factors in cyclic works and atypical non-cyclic works. As for repetitive work, body posture was significant factors affecting on musculoskeletal disorders while atypical works seemed to have none which implied that the necessity of taking psychosocial factors into account for assessment of hazards. Complain rate in repetitive works was highest shoulder, back, and neck or wrist in sequence. However, there existed no consistent trend in complain rate in atypical works. And, though weight of manufacturing objects was a common factor that can partly explain musculoskeletal complain, time duration was significant in atypical work whereas repeatability and body posture were significant in repetitive works. As being the results, to summarize, it could be said that application of conventional ergonomic assessment techniques regardless of repetitiveness would be fruitless, and that the necessity of a unique methodology focused on atypical non-cyclic works should not be neglected.
