Objectives: This study was conducted toestimate quartz concentrations and contents in the airborne respirable dust from various industries. Methods: A total of 818 samples were collected from 174 industries. Respirable dust samples were collected using a cyclone equipped with a 37 mm, $5{\mu}m$ pore size PVC filter. The quartz concentrations were identified using the intensity of the absorption peak of quartz at $799cm^{-1}$ by Fourie Transformed Infrared Spectroscopy(FTIR). Results: The respective geometric means for quartz concentrations in the respirable dust were 0.0050, 0.0049, 0.0025, and $0.0019mg/m^3$ in foundries, ceramics, construction, and cement/stone. The geometric mean of quartz contents analyzed by FTIR were respectively 3.43, 1.99, 1.04, and 0.82% for ceramics, foundries, cement/stone, and construction. The rate of exceeding the Korean Occupational Exposure Limit($0.05mg/m^3$) was 2.03%, but rate of exceeding the American Conference of Governmental Industrial Hygienist(ACGIH) Threshold Limit Value($0.025mg/m^3$) was 7.12%. Conclusions: Given that foundries had a higher quartz concentration, there is a need to reduce respirable dust, such as through wet operation. In order to protect the health of workers exposed to mineral dust, it is necessary to actively consider strengthening the Korean Occupational Exposure Limit.

정경선,Jung, Kyoungsun The Basic Science Institute Chosun University 2010 조선자연과학논문집 Vol.3 No.4

Recently, number of studies for porous silicon have been investigated by many researchers. Multistructured porous silicon (PSi), distributed Bragg reflector (DBR) PSi, has been a topic of interest, because of its unique optical properties. DBR PSi were prepared by an electrochemical etch of $P^{{+}{+}}$-type silicon wafer of resistivity between 0.1 $m{\Omega}cm$ with square wave current density, resulting two different refractive indices. In this work, We have fabricated a simple and portable organic vapor-sensing device based on DBR porous silicon and investigated the optical characteristics of DBR porous silicon. DBR porous silicon have been characterized by FT-IR, Ocean optics 2000 spectrometer. The device used DBR PSi chip has been demonstrated as an excellent gas sensor, showing a great senstivity to a toxic vapor (TEP, DMMP, DEEP) at room temperature.

Purpose: The purpose of this study was to identify the effects of structured information provided on self care knowledge, self care performance, and functional status. Method: The data were collected using self care knowledge and performance assessment tool, and functional status assessment tool from both group hospitalized patients at D hospital in Busan. Results: There was a significant improvement(p=.032) in self care knowledge in experimental group compared to the control group. But there were not improvement in self care performance and functional status in experimental group compared to the control group. But comparing to pretest and posttest in experimental group, There were significant improvement in self care performance (p=.003) and functional status(p=.013). Conclusion: Structured information provided showed increased in the degree of knowledge, self care performance, and functional status. But the effect size of program which had been developed in this study was estimated small, so there is needed to modify this program and to research repeatedly.

정경선(Jung, Kyung-seon),김태복(Kim, Tae-bok) 한국물류학회 2011 물류학회지 Vol.21 No.3

최근 몇 년간 물류 비즈니스모델에 대한 학자들과 실무자들의 관심이 커져 왔다. 실제로 훌륭한 비즈니스 모델은 기업의 수익을 가져다주기 때문에 그 실무적 가치가 크다. 본 연구에서는 주요 물류 저널을 중심으로 비즈니스 모델에 관한 폭넓고 체계적인 문헌 연구를 진행하였다. 이러한 이론적 고찰을 통해 비즈니스 모델의 기본 개념을 살펴보고, 물류 비즈니스 모델의 구성 요소를 찾고자 하였다. 본 연구에서는 일반적인 비즈니스 모델의 개념에 대한 문헌 연구를 바탕으로 물류분야의 저널에 발표된 주요 논문들을 비즈니스모델 관점에서 분석하였다. 본 연구를 통해 정리된 물류 비즈니스모델의 구성요소들이 향후 이론적 연구와 실무적 적용을 기초자료로 활용될 수 있을 것으로 기대된다. The business model has been the focus of considerable attention by practitioners and academics in recent years. Actually, a desirable business model is a concept with enormous practical value because it brings a rich stream of profits. In this paper, we provided a broad and systematic review of related literatures dealing with the business model on several top journals in the area of logistics. In this comprehensive review and survey, we have attempted to explore the origin of the business model concept and building elements of logistics business model. We followed a multi-step process to conduct this study. At first, we begin by briefly reviewing the emergence of the business model concept. And then, we searched for related articles published in leading academic journals and reviewed main articles studying logistics-related business model by analyzing them through business model perspective. We hope that this study could serve as a guideline towards a more extensive study of logistics business model.

The present study investigated the girls children`s perceived competence through the dance. We revised the Harter`s Perceived Competence Scale for Children(Harter, 1982) and Mendelson`s Body-Esteem Scale for Children(Mendelson, 1982) to adopt korean elementary third, fourth, fifth, sixth grade students. The Korea version questionnaire consisted of seven items on social competence, seven items on physical competence, seven items on general self-worth. The instrument showed adequate reliability and validity. The subjects who were training regularly in the dance of Chonbuk`s Chonju, Iksan, Gunsan City were randomly selected. The total 168 primary girls students completed the questionnaire during practicing and studying. The subjects were divided into two groups based on dance participation; one was dance activity(DA) group(over 6 months), the other was non dance activity(NA) group. The results were as follows ; First, the scores of social competence, physical competence, general self-worth variables in DA group were significantly higher than those of NA group(p<Ol). But the scores of body-esteem in NA group were significantly higher than those of DA group(p<.01). Second, there were significant differences in all variables between groups(p<.01), but there were no significant differences in grade. There were significant differences in social competence and general self-worth in variables interaction(p<.Ol) by two-way ANOVA analysis. Body-esteem was showed significant differences in variables between groups, grade, and interaction by two-way ANOVA analysis(p<.01). As the results, dance activity after school affected positive influence to the perceived self-competence of elementary school students.

물류서비스 계약의 결정요인에 관한 연구

물류서비스 아웃소싱 산업이 지속적으로 성장하면서 끊임없이 제기되는 이슈 중의 하나는 서비스이용자의 비용절감과 서비스제공자의 수익성 확보 여부이다. 국내의 많은 기업들이 물류서비스 아웃소싱을 하고 있지만, 원하는 수준의 아웃소싱 효과를 얻지 못하는 경우가 많고, 물류서비스 제공기업들도 불확실한 시장상황과 과도한 단가경쟁으로 수익을 확보하지 못하고 있다. 본 연구에서는 국내 주요 아웃소싱 거래기업을 대상으로 전문가조사를 실시하여 물류서비스 계약의 현황을 조사하였다. 또한, 현재 운영 물류관련 표준계약서와 기타 서비스 표준계약서를 분석하였다. 이를 통해 국내 물류서비스 계약이 서비스의 범위와 종류, 그에 따른 서비스 규모와 비용 및 수익구조에 가장 큰 영향을 받는다는 것을 알 수 있었다. 그리고 서비스 제공기업은 계약을 통해 수익을 확보해야 하기 때문에, 제공서비스의 수준과 부가가치 서비스 제공 여부, 계약 기간과 절차 등에 좀 더 민감하게 반응하고 있음을 알 수 있었다. 또한 전문가 조사결과를 바탕으로 주요 계약요인을 도출함과 동시에 기존 계약서 분석을 통해 모듈화된 물류서비스 표준계약 조항을 제안할 수 있었다. 본 연구는 물류서비스 아웃소싱 이용자와 제공자 그룹을 대상으로 한 대량의 조사가 이루어지 않았다는 한계점과 동일한 물류서비스를 제공하는 물류기업들 간의 비교조사와 그들의 이용자 기업 간의 계약 성과 인식에 대한 세부적인 개별조사를 병행하지 못했다는 한계점이 있다. 향후에는 본 연구의 결과를 바탕으로 개선된 구조의 연구모형으로 더 세부적이고 정량적인 연구 분석이 가능하리라 생각한다. As the popularity of logistics service outsourcing has been continuously growing, one of the most frequently addressed issues is how to estimate the effect of cost reduction for users and profit gains from outsourcing contract for providers. Many manufacturing companies agree that logistics outsourcing helps to reduce their operating costs, but some other companies still do not achieve the cost saving or do not trust logistics service providers, so they keep up in-house logistics operations. On the other hand, logistics service providers have low profitability from domestic business activities since they should meet the requirements for highly customized and diverse services from customers and unstable market situation. This study provided the status report dealing with logistics service contracts in Korea. From the focused group interview with logistics professionals, we found out that service scope, scale and cost structure are the most influential factors affecting logistics service contracts. Also, logistics service providers are more sensitive than users regarding value-added logistics service, contract duration and process. Moreover, this study also proposed the standard clauses for logistics service contract and types of logistics contract applied in current logistics fields. As a result, it is expected that these achievements from this study can be utilized to improve the satisfaction of logistics outsourcing in upgrading service quality and customer service level.
