The unsafe act and unsafe condition is induced by the fundamental cause factors of industrial accidents. In this paper, stress is classified into job, life and workplace stress. Therefore, the purpose of this paper is to develop a Korean stress model focused on the unmarried workers in order to prevent fundamental industrial accidents. The results of this paper are followed. First, the oriental culture and idea in Korea is directly connected to the central axis of all life. Accordingly, concrete and systematic safety management methods should be proposed from the point of Korean culture. Finally, the industrial accident questionnaire needs an item that reports the mental and physical condition of workers in order to prevent occupational diseases.

The UV laser trimming can be useful to have an accurate performance specification of the passive waveguide devices. In order to measure the change of the refractive index of polymer overclad layer under the irradiation of uv light in a high precision Bragg grating is fabricated on the silica core of planar waveguide and the corresponding transmittance spectrum was analyzed. An effective refractive index change of $4.7x10^{-5}$ was obtained for a straight waveguide when its $60{\mu}m$-thick overclad was irradiated by UV laser pulses of its total fluence 24 $J/cm^2$.

Currently, the preferred processing of a user-centered ROI(Region-of-Interest) or a specific region of image to transmission and decompression of a full image is needed in different applications, specifically mobile applications. Here, we have to study how different factors affect ROI coding methods. Therefore, an application can select an ROI coding method and several parameters suitable for the environments. The ROI coding methods used in the study are Maxshift and Implicit and the parameters are tile size, image size, code block size, ROI importance and the number of lowest resolution levels. This study shows the experimental results between the different parameters and the two ROI coding methods.

The purpose of this study is to illustrate the potential for clinical improvement in treating a patient with a case of Posttraumatic Knee Stiffness with a combination of Korean medicine therapy. We treated the patient with acupuncture, electroacupuncture, CHUNA manual therapy and Interferential Current Therapy from $5^{th}$ December 2016 to $13^{th}$ January 2017 (total 29 times) by evaluating knee function with VAS score. After six weeks of treatment, this patient achieved effective outcome following the technique, showing that clinical symptom as able to walked and pain was relieved, VAS changed from 10 to 2 and the knee flexion ROM (active/passive) changed from 30/60 degrees to 120/140 degrees. This result shows that Korean Medicine therapy may be an effective option for Posttraumatic Knee Stiffness. Further clinical studies are needed to clarify the effect of Korean Medicine therapy on Posttraumatic Knee Stiffness.

Actinoplanes teichomyceticus ATCC 31121 was mutated with UV to obtain a superior mutant strain with increasing level of teicoplanin production. In this investigation lethal curve was obtained and the optimal condition to induce mutagenesis was determined and to isolate the desirable mutant strain. It was also confirmed that teicoplanin activities by agar diffusion method to be compared to the mother strain. One mutant strain, T991014-1 that had the highest teicoplanin productivity was finally selected for further investigation including fermentation pattern. The mutant was characterized by the various tests such as amylase activity, protease activity, antibiotic resistance, autotoxicity, and productivity.

본 연구는 관세행정 환경의 급격한 변화로 관세행정 기능의 사명별 중요도가 변화되고 행정방향도 주변분야까지 확대되었다. 이에 위험관리의 패러다임도 업무별 개인 차원의 적발과 단기성과 위주에서 지능적이고 정부 차원의 장기성과 위주로의 변화가 요청된다. 연구 결과를 요약하면 첫째로 관세행정의 위험관리에서의 변수간의 통계적 상관관계는 높게 나타났다. 둘째로 계획, 점검, 개선 단계의 변수만이 위험관리 성과인 만족도에 영향을 미치고, 집행단계는 영향을 주지 않는 것으로 나타났다. 셋째로 각 단계에서 조직성과에 긍정적인 영향을 미치는 변수는 계획단계는 안정성과 민주성 및 투명성이, 점검단계에서는 신속성과 정확성 및 합법성이, 개선단계에서는 혁신성과 교육성 및 홍보성이 위험관리 만족도에 영향을 주는 것으로 나타났다. 향후 관세행정에서 통합전략적 위험관리를 위해 첫째로 취약성은 최소화하고 강점을 강화키는 사전예방적 기능이 확보되어야 한다. 둘째로 위협사건 최소화와 적출기능이 확보되어야 한다. 셋째로 발생손실의 복구와 교정기능이 확보되어 고객을 감동시켜야 한다. 넷째, 변화에 대응하여 지속적으로 성장할 수 있는 기능이 확보되어야 한다.

DSME has developed Sub-assembly Welding Robot System(SWRS) in order to increase the productivity of arc welding and to improve hazard and unclean environments in shipbuilding. DSME's SWRS includes a number of equipments such as four overhanging 6-axis articulated robot manipulators(10kg pay-load), gantry system, vision system detecting the workpiece automatically, and OLP system using the CAD data and a central control system integrating an anti-collision module. The SWRS was installed in CAS(Component Assembly Shop) of DSME's OKPO shipyard in August 2006, and now SWRS is running well in site.

Colistin produced from Penibacillius polymyxa was widely used as an antibiotic active against gram-negative bacteria and as feed additive. This research studied on increment of colistin productivity by mutation of P. polymyxa. As a result, several mutants were obtained from the strain by UV radiation and NTG treatment. They produced approximately 8.5${\sim}$9.0 g/L of colistin in flask and jar culture. Colistin productivity of the mutant, named Penibacillius polymyxa CBY, showed 100 times than that of wild type. When Penibacillius polymyxa CBY fermented in the optimal medium, it produced up to 18 g/L of colistin in jar fermentation.
