It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

The cement based mortar is typically used as the surface finishing material for apartment floor. By the way, the crack is easily appeared with the lapse of time in this floor mortar because of the shrinkage effect of the cement. In our country, the most popular expansive additive is hauyne(CSA) or free lime(free-CaO) system. The types of shrinkage in the surface finishing mortar is known as plastic shrinkage, dry shrinkage and autogenous shrinkage. In this study, the expansive properties of the free lime system with various size distribution is analyzed. In particular, the experiment for the expansive properties is carried out by using the soundness molds and with various humidity and dry setting conditions. In addition, the difference of dry shrinkage properties between the cement with expansive additives and OPC is investigated under different conditions of water/cement ratio and sand/cement ratio.

박종탁,류원률 대구보건대학 2001 대구보건대학 論文集 Vol.21 No.-
The objective of this study is to investigate optimum condition for laccase production. The white rot fungi Pleurotus sp. and Schizophillum sp. were studied for their abilities to produce laccase. Pleurotus sp. was proven to be excellent in producing lignin peroxidase with high specific activity. The optimum pH, agitation speed, 2,5-xylidine concentration, and temperature conditions for laccase production by Pleurotus sp. were pH 4.5, 200 rpm, 1.0 mM, and 25℃, respectively. For nitrogen sources, ammonium tartrate was good for laccase production, while 0.4% ammonium tartrate concentration showed the highest potential for laccase production. The maximum laccase activity in shaking-flask batch culture were 1,500 U/L. the maximum laccase activity in jar-fermenter culture were 1,700 U/L.

A bicriteria reliability apportionment problem for a system consisting n subsystems with time-dependent reliability is manipulated in this paper. This reliability design problem with two objectives determines the optimum level of component reliability and the number of redundant components at each subsystem. The problem is formulated as a bicriteria nonlinear mixed integer programming problem, subject to several design constraints. Also, a hybrid genetic algorithm is used in this paper to find an optimal or near optimal solution and we propose the method which search the Pareto solutions of bicriteria reliability apportionment problems. Furthermore, numerical experiments are illustrated to demonstrate the efficiency of the proposed method.

The studies was conducted to establish the indoor overwintering methods for productive honeybee colonies in the wintering chamber which provides satisfactory inside temperature ranging 2∼9。C and ventilation for the wintering honeybee colonies in Korea. Mortality of the indoor wintered honeybee colonies was 6.3∼7.1% during the winter season of 1997-1998 and 5∼10% during the winter season 1998∼1999. The decreased rates of colony weights during the wintering season were 10.6∼10.7% in the strong colonies and 10.2∼11.7% in the weak colonies. The increased rates of colony population overwintered in the chamber were 136.1∼142.3% in the strong colonies and 128∼136.5% in the weak colonies.
고농도 유기성폐수의 처리를 위한 Jet loop bioreactor의 개발
박종탁,류원률 대구보건대학 2000 대구보건대학 論文集 Vol.20 No.-
A jet loop bioreactor was used for the biological treatment of dyeing wastewater. Volumetric oxygen transfer coefficient(k_(La) of jet-loop reactor was significantly larger that of air-lift reactor. When HRT was 48 hours, almost all organics were removed by jet loop bioreactor and the removal efficiencies of BOD, COD_(Mn) and COD_(Cr) were 100, 87.2 and 83.5%, respectively. When HRT was 48 hours, the removal efficiencies of BOD, COD_(Mn), and COD_(cr) were 100, 80.1 and 79.4%. respectively. The specific removal rate was proportionally increased from 0.25 to 1.72 kg COD_(Mn)-removed/kgMLVSSㆍday as specific loading rate was increased from 0.25 to 1.60 kg COD_(Mn)/㎏MLVSSㆍday. Therefore, jet loop bioreactor could treat effectively dyeing wastewater containing high concentration of organic compounds.

형사법상 예비․음모죄에 대한 재검토 : 음모죄 폐지와 예비죄 정비
이종률, 이덕인 東亞大學校 法學硏究所 2010 東亞法學 Vol.- No.49
우리 형법은 예비와 단순한 음모를 모두 처벌하고 있는데, 범죄의 음모란 범죄를 실행하려는 의사의 교환단계에 불과하고, 범죄 실행이 포착되는 준비과정은 아니기 때문에 오늘날 음모행위만을 독자적으로 처벌하는 국가는 거의 없다. 아울러 예비행위에 대한 처벌에 있어서도 형법제정 당시와는 근본적 측면에서 이를 다시 검토해야 할 필요성이 강하게 부각되고 있다. 그러나 형법의 전면개정을 염두에 두고 2010년 10월 25일자로 입법 예고된 법무부의 형법일부개정안과 개정연구회시안(2008)에서는 이와 관련된 논의가 심도 있게 전개되지 아니하였다. 비교법적으로 보더라도 총칙에 예비․음모규정을 두고 있는 나라는 우리나라를 제외하면 중국에 불과하고, 더욱이 예외적인 처벌을 총칙에서 선언하고 있는 나라는 우리나라가 유일하다. 형법총칙의 예비․음모규정을 폐기하지 아니할 경우 향후 형법각칙 및 형사특별법에서 무분별한 예비․음모규정을 양산할 우려가 있고, 형법총칙은 예외를 원칙으로 선언하는 규범이 아니라 원칙만을 규정해야 하는 형사기본규범이기 때문에 예외에 대한 언급은 가급적 회피되어야 한다. 따라서 특정범죄의 예비행위에 대한 처벌의 필요성이 있는 경우에는 각칙에서 이에 대한 구성요건을 구체화하여 처벌하는 것으로 그 목적을 달성할 수 있으므로 총칙규정의 예비․음모조항은 삭제되어야 한다. 또한 각칙에서도 처벌의 실익이 없는 기본범죄의 예비행위는 비범죄화되어야 하며, 처벌의 필요성이 있는 경우에도 법정형의 제한방식을 재검토하여 과도한 처벌은 합리적으로 조정해야 할 것이다.
한국과 미국의 정치사회화 연구 : 문제점과 새로운 방향 Problems and New Directions
이종렬 한국경제교육학회 2003 경제교육연구 Vol.10 No.1
아동기에 형성되는 정치정향이 정치체계의 안정과 존속의 조건이 된다는 가정에서 출발한 점치사회화 연구는 1960-70년대에 전성기를 이루었다. 정치사회화 연구는 당시에는 정치학의 새로운 패러다임을 열 것이라는 기대를 갖게 하였다. 그러나 1980년대 중반 이후의 정치학 분야에서는 그 연구 성과를 거의 찾아볼 수 없는 ‘사라진 역사’를 보이고 있다. 한국에서의 정치사회화 연구는 아직까지도 미국의 연구 경향을 소개, 도입, 적용하는 단계를 넘어서지 못하고 있으며, 이론적 체계의 확립이나 시민교육 영역에서의 구체적인 공헌 없이 정치사회화에 관한 관심은 매우 다양한 분야로 확산된 모습을 보이고 있다. 미국에서나 한국에서나 정치사회화 연구는 '실패'한, 또는 적어도 연구 초기의 '기대'를 충족시키지 못한 분야라 할 수 있다. 이는 정치사회화 개념과 이론적 툴이 지니는 문제점과 함께 정치사회화 연구방법론이 지니는 한계에 기인한 것이었다. 최근에는 전통적인 정치사회화 연구에서 벗어난 대안적인 연구전략들이 탐색되고 있다. 특히, 아동과 청소년들의 정치학습이 이루어지는 과정 그 자체에 관한 질적 접근의 연구와 종단면적 연구의 중요성은 매우 크다. 그리고, 이러한 아동과 청소년의 정치적 성장 과정에 관한 연구는 이들의 정치세계를 구성하는, 시민교육의 관점에서 관심을 가져야 할 내용 요인으로서의 민주적 태도들을 보다 심층적으로 분석하는 연구가 이루어져야 할 것이다. The purposes of this essay are 1) to analyse and compare the political socialization research trends in Korea and the United States, 2) to discuss the problems of political socialization research, and 3) to make some suggestions for new directions. Research on political socialization began in the late 1950s and soon became a 'growth stock,' and enjoyed an enormous success. But, barely two decades later, it became 'bear market.' In Korea, political socialization research followed the American trends with 10 years time interval. According to systems theory, political socialization was regarded as the response mechanism for system's stability and persistence. But, the relationships among children's attitudes, adult's behaviour and the political system were just assumes which didn't verified. With methodology, pencil-paper surveys with fixed-choice questionnaires were inappropriate. To explain the 'persistence' of children's attitudes, longitudinal studies is necessary. But, there was rare such researches about children. For future researches, I ) new concept of youngsters free from 'tabula rasa' figure, 2) qualitative analysis focusing on the political learning process by which children construct the political world, and 3) new strategy with citizenship education perspective are desirable.
