This study examined all the papers published in the Journal of Occupational Health Nursing from 1991 to May 2000 based on an objective frame of evaluation. The purpose of study is to prospect the trend of occupational nursing research and to provide an optimal direction for future occupational nursing service. The results of total 94 studies were analyzed as follows. 1. The number of papers published in 1991-1992, 1993-1995, 1996-1997 was not significantly increased. However, the number of papers were obviously increased after 1998. 2. In the design of research, survey studies were definitely dominant. But, they are gradually decreasing and experimental studies are increasing. 3. In the fields of research, health problems, health risk factors and health awareness were higher than others. Occupational health nurse's task and job satisfaction were main areas of research until the middle of 1990's. However, after then, not only health problem, risk factor and awareness of health but also health promotion and preventive health behavior are increasing in the research areas. 4. The collaborative researches have gradually increased and the type of author has been varied. The number of researches completed by funds was undertaking only 3 among the total 94. 5. In the research analysis, except for case studies and literature studies, the research subjects have been shifted from the occupational health nurses to the industrial workers, and more diversified. The sample size has been enlarged and the major place of the study is industry. The questionnaire was used in many studies as instrument for data collection and measurement. But, complementary methods of diverse instruments have been increased. The method of data analysis has obviously showed some changes moving from descriptive statistics to inferential and advanced statistics. 6. The ways of nursing intervention have prominently diversified in experimental studies. The contents of case studies were mainly focused on the health management programs and activities in industry. The research concepts and the contents of literature study were also changed progressively in various way. Based on the above findings, conclusions are extended to the following discussion: Since the Korean Academic Society of Occupational Health Nursing was instituted in 1990, the researches of occupational health nursing have shown an acute methodological development in both quantity and quality. However, they were considered still in the lack of research verifying the effects of nursing intervention program. Also, the development of nursing intervention and nursing theory lacked. Therefore, more empirical researches are strongly needed to utilize the field of occupational health nursing in Korea Researchers are also encouraged to exert more efforts to get research funds.

This study inquired following research questions by a narrative research method : What was the job of an engineer in mechanical design field? How did he fulfill his job-related learning in his workplace? What were the context and the characteristic of the job-related learning in the workplace? And some implications of the job-related learning on engineering education were discussed. We identified that the research participant's career as a mechanical engineer has developed through three stages. At first, he engaged on conceptual design of a semi-conductor test machine through self-initiated learning from basic to whole system of the machine. At second stage, he leaded a design group for the concrete design of a ball type semi-conductor test machine. In this stage he learned the meaning of cooperation and cooperative learning. At third stage, he initiated to found an entrepreneur company that was specified to design a semi-conductor test machine. He became CEO of the company. He learned the R & D policy making through contacts with global company, visiting exhibition in abroad. Eventually his main task as a mechanical engineer was the problem solving in the process of machine design. He had experienced and learned through his works : project management, independent fulfilling of tasks, functional analysis and reverse engineering, conceptualizing and test, cohesive cooperation, dialogue and discussion, mediation of conflict, human relationship, leadership. The implication of the narrative analysis on engineering education is, proposed, to give the students more chances to experience and to learn such activities.

Background: The aim of this study was to analyze the demographic and clinical characteristics of male breast cancer patients in Serbia, and furthermore to determine overall survival and predictive factors for prognosis. Materials and Methods: In the period of 1996-2006 histopathological diagnosis of breast cancer was made in 84 males at the Institute for Oncology and Radiology of Serbia. For statistical analyses the Kaplan-Meier method, long-rank test and Cox proportional hazards regression model were used. Results: The mean age at diagnosis with breast cancer was $64.3{\pm}10.5$ years with a range from 35-84 years. Nearly 80% of the tumors showed ductal histology. About 44% had early tumor stages (I and II) whereas 46.4% and 9.5% of the male exhibitied stages III and IV, respectively. Only 7.1% of male patients were grade one. One-fifth of all patients had tumors measuring ${\leq}2cm$, and 14.3% larger than 5 cm. Lymph node metastasis was recorded in 40.4% patients and 47% relapse. Estrogen and progesterone receptor expression was positive in 66.7% and 58.3%, respectively. Among 14.3% of individuals tumor was HER2 positive. About two-thirds of all male patients had radical mastectomy (66.7%). Adjuvant hormonal (tamoxifene), systematic chemotherapy (CMF or FAC) and adjuvant radiotherapy were given to 59.5%, 35.7% and 29.8% patients respectively. Overall survival rates at five and ten years for male breast cancer were 55.0% and 43.9%, respectively. According to the multivariate Cox regression predictive model, a lower initial disease stage, a lower tumor grade, application of adjuvant hormone therapy and no relapse occurrence were significant independent predictors for good overall survival. Conclusions: Results of the treatment would be better if disease is discovered earlier and therefore health education and screening are an imperative in solving this problem.

This study investigated the problem of mean-field bias correction under the assumption that the radar and rain gauge rainfall data follow the log-normal distribution. Regression curves for the average, median and mode of the radar and rain gauge rainfall were derived and evaluated for their usefulness. Additionally, these regression curves were compared with those derived under the assumption that the radar and rain gauge data follow the normal distribution. This study investigated the regression results for the Typhoon Meami occurred in 2003 as an example. As results, three regression lines with the radar rainfall as the independent variable were found to underestimate the rainfall, while those with the rain gauge rainfall as the independent variable to overestimate. Among three types of regression curves considered, the result for the average was most appropriate. However this case was found to be inferior to the regression line passing the origin under the assumption of the normal distribution with the rain gauge rainfall as its independent variable. So it was hard to conclude that the consideration of the log-normality on the correction of radar rainfall is beneficial.

This paper studied the resolving the regional conflict method through the community capital formation. For this purpose, the theoretical background about the social capital, function of the social capital and component, and regional conflict factor were organized. In addition, it analyze empitically through the survey. First, in order to resolve the frequency analysis result regional conflict, the social capital formation was exposed to be important. Next, the regression analysis result, the factor of social capital and the local egoism, the local participation, and the problem of local areas, each, it was expressed as the coefficient of determination 5.1%, 5.5%, 1.6%, and F value showed up as 4.030, 4.3,51, 1.194. This demonstrates that it is decreased the regional conflict as the social capital formation is high. That is, the social capital formation was proved at the resolving the regional conflict that there was lots of the correlation. The community and penis organizationThe local residents should cooperate together and it should try. Particularly, the 20 generations and 30 generations in which the social capital is weak, the social capital formation strategy about the 20 generations and 30 generations should be studied.

The Construction Standard Unit Price (CSUP) sets the standard for calculating the estimated construction cost. The CSUP is used as basic data for preparing a standard price for public construction. Currently, the CSUP is calculated in consideration of the market and construction field conditions. However, a long-term management plan was established to prepare revised standards. As part of the plan, a field survey was conducted on changes in construction conditions and market prices. However, the plan continued for more than 5 years. Thus, the plan has a problem of difficulty continuously managing primary activities that have high importance and high price volatility. Therefore, to efficiently manage the CSUP, this study identifies the primary activities of the CSUP and presents a management plan. Through importance analysis and unit price volatility analysis, 242 primary activities in 35 activity groups were identified. Also, a management plan is presented based on the importance levels of activities. The primary activities and management plan could enable the timely revision of important activities. The results of this study provide a base for reflecting the appropriateness of construction cost criteria on time.

Purpose This study re-analyzes Jung 2012's data using the time interval based analysis to examine if the process of idea generation is in good currency throughout the ideation sessions. In this way, the relationship between extraversion-introversion personality trait and ideation performance in the context of computer-mediated idea generation can be better understood. Design/methodology/approach A $2{\times}4$ factorial design was used, crossing personality differences (extraversion and introversion) with the degree of stimuli (0, 20, 40, and 80 high-quality ideas). Participants were randomly assigned to one of eight treatment conditions. The group simulator is used to measure individual level performance. The number of unique ideas generated by individuals and the exact time stamp when each idea was submitted were analyzed to compare performances. Findings The results show that introverts' performances significantly drops after about the middle stage of the ideation session, whereas extraverts do not seem to feel time constraints throughout the ideation session, resulting in superior divergent thinking, which is a major key to understand creative productivity in the problem-solving process. Since extraverts tend to yield a larger pool of ideas, another interpretation is that group composition with extraverts compared with introverts may create a logically larger group, which is important to improve the performance of idea generation group.

Wooded areas that are a part of school campuses are one type of urban forest. Most schools located in an urban environment make an excellent setting for a forest in terms of location and area. These kinds of wooded spaces also make the city greener and healthier. As a place where students spend a great deal of time, schools can also be a venue for environmental education. The creation of wooded areas in schools currently has focused on the end result only; by ignoring student needs and participation, these areas have not had a significant influence on student environmental education. Previous studies based on questionnaire survey are significant in that they have quantified subjective qualitative data via Likert Scale. There has been, however, a problem in quantifying the more ambiguous subjective data. Therefore, this paper has attempted to investigate those factors that have an influence on student satisfaction with the wooded areas of their school campus using Fuzzy Theory with elementary school students in Gyeongsangbuk-do. A change was observed in terms of the ranking of arithmetic mean values of 'school peculiarity' and 'emotion evolution' and center of gravity, which has adopted Fuzzy Theory, proving that Fuzzy Theory could rationally objectify qualitative data such as human thoughts. In terms of the influential factors on the satisfaction with school forests(regression coefficient), 'school uniqueness(0.159)' was the highest, followed by 'many trees(0.142),' 'importance of nature(0.136)' and 'emotion evolution(0.130).' This paper may therefore be useful as basic data for objective questionnaire surveys and the development of school forests.

InSb has received great attentions as a promising candidate for the active layer of infrared photodetectors due to the well matched band gap for the detection of $3{\sim}5\;{\mu}m$ infrared (IR) wavelength and high electron mobility (106 cm2/Vs at 77 K). In the fabrication of InSb photodetectors, passivation step to suppress dark currents is the key process and intensive studies were conducted to deposit the high quality passivation layers on InSb. Silicon dioxide (SiO2), silicon nitride (Si3N4) and anodic oxide have been investigated as passivation layers and SiO2 is generally used in recent InSb detector fabrication technology due to its better interface properties than other candidates. However, even in SiO2, indium oxide and antimony oxide formation at SiO2/InSb interface has been a critical problem and these oxides prevent the further improvement of interface properties. Also, the mechanisms for the formation of interface phases are still not fully understood. In this study, we report the quantitative analysis of indium and antimony oxide formation at SiO2/InSb interface during plasma enhanced chemical vapor deposition at various growth temperatures and subsequent heat treatments. 30 nm-thick SiO2 layers were deposited on InSb at 120, 160, 200, 240 and $300^{\circ}C$, and analyzed by X-ray photoelectron spectroscopy (XPS). With increasing deposition temperature, contents of indium and antimony oxides were also increased due to the enhanced diffusion. In addition, the sample deposited at $120^{\circ}C$ was annealed at $300^{\circ}C$ for 10 and 30 min and the contents of interfacial oxides were analyzed. Compared to as-grown samples, annealed sample showed lower contents of antimony oxide. This result implies that reduction process of antimony oxide to elemental antimony occurred at the interface more actively than as-grown samples.
