김철호 조선대학교 2011 국내박사

현대적 의미의 외식산업은 제공하고 있는 제품이 식사나 음료와 같은 유형의 상품 이외에도 더불어 제공되는 부수적인 인적 서비스, 분위기 등의 무형의 상품 등으로 구성된다. 따라서 유․무형의 상품에 대한 품질 문제로부터 고객을 보호하고 소비자들의 필요와 욕구에 부응할 수 있는 객관적 평가 기준에 부합한 시설환경과 서비스를 갖추고 운영되어야 한다. 그러나 최근 외식산업의 비약적인 발전과 한류열풍에도 불구하고, 국내 외식업을 이용하는 고객들은 우리 전통고유 음식의 맛, 가격, 분위기, 서비스 등에서 지역에 따라 혹은 비슷한 수준의 동종 업종에서도 많은 차이가 발생하여 그 수준을 신뢰하지 않고 있으며, 규모별, 지역별 공통 서비스 품질평가 체계가 없어 많은 혼란을 겪고 있다. 따라서 소비자들의 욕구(needs)와 필요(wants)에 부응할 수 있으며, 경영주들이 고객들로부터 인증된 고객 지향적 품질관리를 할 수 있는 평가기준 마련의 필요성이 대두되고 있는 실정이다. 그러나 지금까지 외식산업에 대한 연구는 매출증대 방안이나 메뉴계발 등 기업활동에 대한 연구와 외국연구에 바탕을 두어 국내 실정에 맞지 않는 이질적인 면을 내포하고 있으며, 부분적이고, 획일적인 속성과 기초적인 기술적 자료를 토대로 한 연구에 치우쳐 있는 실정이다. 그러다보니 현실적으로 외식산업을 종합적으로 평가할 수 있는 도구가 개발되어 있지 않고, 또한 정책적으로도 종합하여 집행하고 평가 할 수 있는 기구가 마련되어 있지 않다. 현재 각 시․도 차원의 위생과에서 종합적으로 처리하는 기능을 가지고 있으나 단지 식품 위생법에 관련된 내용에 국한되어 있으며, 외식업의 주요한 축을 담당하는 음식업중앙회가 있으나 그 역할의 한계 및 위생문제 등으로 종합적으로 외식업체를 평가, 심의하는 데에는 문제가 있다. 더욱이 외식산업에 대한 객관성에서 문제가 발생할 수 있다. 즉 객관적인 평가결과, 평가항목, 가중치 설정의 객관성문제, 고객의 만족도, 외래객의 이용평가 및 제반시설 등을 종합적으로 분석한 후 평가가 이루어져야 한다. 따라서 명확하고 객관성 있는 평가척도를 개발하여 외식업체를 종합적으로 평가하고, 집중 육성할 수 있는 발판을 마련해야 한다. 홍콩은 약 8천여개의 레스토랑을 대상으로 내부 위생 정도에 따라 ‘별(star)’로 레스토랑의 등급을 표시하고 있는데, 최고 수준인 ‘5개의 별’ 등급을 받은 식당은 로고(logo)를 공개할 수 있으나 그보다 낮은 등급을 받은 식당은 로고를 공개할 수 없도록 규정하고 있다. 이와 더불어 식당 위생 상태에 대한 검사는 매년 실시되며 그 결과에 따라 등급이 조정된다. 또한 멕시코의 관광부와 보건부는 식품위생기준을 확립하기 위한 법령을 제정하였는데, 법 제정의 목적은 호텔, 레스토랑을 비롯한 식품 취급업소가 위생의 중요성을 인식하고, 이를 실천하게 유도했다. 이러한 법적 제도적 기준 마련을 통해 많은 호텔과 레스토랑 경영자들은 종사원들에게 관광객에 대한 더 유익한 식사환경을 제공하기 위한 훈련을 시킬 것을 자발적으로 결정하였으며, 관광부는 음식의 조리와 서비스에 있어 높은 수준의 위생과 청결을 달성한 업소에 대해 ‘H’상을 수여하였다. 종업원의 60%이상에게 안전한 식품 취급요령을 훈련시킨 호텔과 레스토랑이 이 상의 수여 자격 대상이 되며 80개의 점검문항에 대해 85%이상의 점수를 획득하여야 한다. 이제 멕시코의 관광객들은 ‘H’상을 받은 업소에서는 더욱 안심하고 식사를 즐길 수 있게 된 것이다. 외국 사례에서 볼 수 있듯이 국내 외식업체도 이용 고객들에게 객관적이고 표준화된 선택기준을 제시할 필요성이 있으며, 세계화, 개방화 시대에 부응하여 한류음식의 선호도가 높은 현실에서 외식산업을 발전시키고 육성시키기 위해서는 외식업 품질평가척도에 대한 장기적이고 종합적인 연구가 필요하다. 그러나 지금까지 외식산업 서비스품질평가에 대한 연구는 매출증대 방안이나 메뉴계발 등 기업활동에 대한 제한된 연구와 외국연구에 바탕을 두어 국내 실정에 맞지 않았다. 특히, 한류에 따른 전통한식의 국제화와 더불어 표준 레시피와 서비스품질 평가척도가 정립되어 있어야 함에도 불구하고 한식의 선호도와 국제화에 따른 국제적 요구에 부응한 척도개발이 부진한 실정이다. 따라서 이러한 문제제기를 바탕으로 전통한식의 국제화를 위한 품질개선을 위해 서비스품질 평가 개발을 위해 본 연구의 필요성을 갖는다. This study was carried out with intent to positively respond to changing environment based on problem consciousness for improving irregular service quality systems of traditional Korean style restaurants, and develope and propose assessment items for a balanced service quality management of rational and future-oriented traditional Korean style restaurants. The result is summarized as follows. First, the all existing food service quality fields such as the flavor of food, menu materials, originality and specialty of menu that are now being taken care of, in terms of maintenance and strengthening, were positively judged, continuing to have to maintain and strengthen them. Second, in terms of sustenance and maintenance, continuous observation and management are needed to remove cases such as a correct publication and stamp of receipts and a collection of unfair charges. Third, for items that need gradual and phased improvement, improvement in service for internationalization is needed in soft items such as diversification of international credit cards, quality of containers use, open through comfortable space creation of kitchen, restriction on the use of disposable items, and improvement in international conversation through development of employees' communication ability that meet the global era. Fourth, division into non-smoking sections or the status of waste disposal, and the variety of side dishes were very restrictively pointed out for focused improvement in supplementation or urgently required items, but a general estimation was positively made. Overall, the importance of evaluation items was higher than the application for the service quality evaluation of traditional Korean food, and was somewhat low for the application proportionate to the importance. But because the proportion was formed in four-point bracket, it is very positive as an evaluation item for the internationalization of traditional Korean food, and items are suitable. Consequently, In four-quarters of menu, price, restaurant, kitchen, environment, facilities, human service, business management, toilet, institutional factor, location and size that had been in common evaluated in the field of the existing food service, the supplementation by maintenance and strengthening and gradual improvement can more improve the service quality of traditional Korean food, as well as become established as the quality for internationalization.

ISPH법을 이용한 2차원 비압축성 유체 유동의 수치시뮬레이션 기법 연구

김철호 인하대학교 대학원 2011 국내석사

연속적인 유체를 이산화 된 입자들로 근사시킴으로써 유체유동을 시뮬레이션 하는 SPH법에서는, 지배방정식인 Navier-Stokes 방정식과 연속방정식을 풀기 위하여, 유체가 약간의 압축성을 지닌다고 가정한다. 이러한 가정은 비 물리적인 압력변동과 작은 계산시간 간격의 제한과 같은 단점을 지니게 한다. 본 논문에서는 이러한 현상을 개선하기 위하여, 유체를 비압축성으로 가정하고 projection method를 이용하여 속도-압력의 연성 문제를 계산하였다(ISPH법). 본 연구를 통하여 개발된 수치해석 기법의 정도를 확인하기 위해 중력파를 계산으로 생성하여 이론적인 값과 비교하였고, 댐 붕괴 현상을 시뮬레이션 하여 유한체적법의 계산결과와 비교하였다. 비교결과 정성적, 정량적으로 서로 근접함을 확인하였다. 또한 비선형성이 강한 자유수면 유동과 유체의 충격하중을 동반하는 문제에의 적용가능성을 확인하기 위하여, 고정된 2차원 바지선에서의 갑판침입수를 시뮬레이션 하였으며, 계산결과를 기존의 실험결과와 비교하여 정성적으로 근사함을 확인하였다. In SPH(Smoothed Particle Hydrodynamics) method which represents the movement of fluidic physical volume with particles, the fluid has been assuming that it is weakly compressible to solve the basic equations composed of Navier-Stokes equations and continuity equation. That leads to some drawbacks such as non-physical pressure fluctuations and a limitation as like small time steps in computation. In this study, to improve these problems we assume that the fluid is incompressible and the velocity-pressure coupling problem is solved by a projection method(ISPH method). The two-dimensional computation results of gravitational wave generation and dam breaking are respectively compared with the results of analytical method and finite volume method to confirm the accuracy of the present numerical computation technique. And, the agreements are comparatively acceptable. Subsequently, the green water simulations of a two-dimensional fixed barge are carried out to inspect the possibility of practical application, those are corresponding the violent free surface motions and impact loads on the upper deck. The green water simulation results are compared with existing experimental results. The agreement between the experimental data and the present computational results is also comparatively good.

김철호 東京大學 1990 해외박사

Bacillus circulans F-2균은 균체외에 3가지의 중요한 효소 즉, 생전분분해효소, Cl-의존성amylase 및 다기능효소인 amylase-pullulanase효소를 분비한다. 이들효소는 유도인자가 존재할때에만 발현되는 유전자 발현조절계가 매우 특이하다. 따라서 이들효소 유전자의 분자생물학적인 해석을 통한 발현기구의 응용 및 효소들의 산업적인 응용연구를 목표로 하였다. 즉, 본 연구에서는 이들의 분자생화학적인 해석을 위하여 이들 요소유전자의 분리, DNA구조해석, 기질특이적 반응성을 해석하였으며 동시에 다기능효소 amylase-pullulanase enzyme의 효소활성부위를 mouse myeloma와 항체생선세포인 spleen의 세포융합을 통한 단클론항체의 제작과 이를 이용한 해석을 통하여 이들 효소의 입체구조와 활성과의 상관관계를 유전생화학적으로 해명하였다. 다음은 3가지 장의 내용을 요약하였다. 1) 생전분분해효소(RSDA; raw starch-digesting amylase) 유전자의 대장균에서의 클로닝과 해석연구 클로닝한 유전자를 pYKA-3라 명명하고 각각의 DNA부분을 subcloning하여 생전분분해활성부위를 해명하고 DNA염기배열을 결정하여 신규의 유전자를 최초로 해석하는 데 성공하였다. 또한 생전분분해능을 갖는 DNA영역을 찾아내어 단백질화학적으로도 부분분해하여 그 영역을 동정하였다. 즉, 본 효소단백질은 분자량 약 90,000달통이 약 50,000만과 40,000달톤의 2개의 domain으로 구성되었으며 각각의 도메인은 subtilisin과 같은 protease에 의해 나뉘어지는 입체구조를 가지는 것으로 확인되었다. 2) Cl-의존성amylase(CDA;치-dependent amylase) 유전자의 분자유전학적 연구 Cl-의존성amylase유전자를 대장균에 클로닝하여 대전균에서 발현된 효소의 정제, 효소활성상관관계 및 Cl에 특이적인 활성화를 해석하였다. 본 효소는 호염성효소보다 염소의온의존성이 약 10배 강하여 혈중내 염소이온의 검출지표로 이용가능성을 해석하였다. 3) 다기능효소 amylase-pullulanase enzyme(APE)의 분자유전학적 및 면역학적 연구 본 효소는 one polypeptide two enzyme의 다기능성효소로 최초로 동정되어 효소활성의 입체구조와 각각의 활성부위의 유전자내 위치결정을 행하였으며 동시에 단클론항체의 제작을 통한 그 위치를 결정하여 최초로 1단백질 2가지 효소의 각각 다른 active site를 검정하는데 성공하였다. 이상의 연구결과를 요약하였으나 본 결과들은 국제학술지에 4편 일본국내학회에 약 22회 발표되었으며 신기능효소의 산업적 이용연구로 중요성이 인식되었다. This dissertation investigates the role of the pioneer Korean christians in beginning indigenous Presbyterian churches in Korea and in translating the Gospels into the Korean vernacular. Protestant christianity was introduced in Korea at a time when traditional religions were in a state of decay. The peoples receptivity to Protestant Christianity was closely related to the religious climate, since they were looking for something new that would quench their religious thirst. They were quick to appreciate the gospel. In addition, the instability of the socio-political situation that wae created through a series of criese in the late nineteenth century encouraged people in Korea to turn to Protestant Christianity. Pioneer Korean Christians who came mainly from northwestern Korea established the first indigenous Presbyterian churches, beginning the first Protestant missions in the forbidden land in which bo missionary was allowed to work, Most of these indigenous churches were self-supporting and self-propagating from the beginning. The indigenous Christians also played a renarkable role in translating the Fospels into the Korean vernacular. They produced two indigenous versions of the Gospels, the Yesoo Shung-Kyo version in Manchuria and the Yi Soo-Chung version in Japan, before growth of Protestant Christianity in Korea, laying the biblical foundation for the Korean Protestant church. The foreign missionaries in Korea carried on their work in the indigenous Protestant churches. They did not claim to be the founders of the Protestan church in Korea, bur they played a remarkable role in training indigenous leadership the developing the soul-winning churches.

김철호 원광대학교 일반대학원 2011 국내석사

The SiC-ZrB2 composites were produced by subjecting a 40:60 vol.% mixture of zirconium diboride(ZrB2) powder and β-silicon carbide (SiC) matrix to spark plasma sintering(hereafter, SPS). Sintering was carried out for 60sec at 1400℃(designation as TP145 and TP146) , 1500℃(designation as TP155 and TP156) and uniaxial pressure 50MPa , 60MP under argon atmosphere. The physical, electrical, and mechanical properties of the SiC-ZrB2 composites were examined. The relative density of TP145, TP146, TP155 and TP156 were 94.75%, 94.13%, 97.88% and 95.80%, respectively. Reactions between β-SiC and ZrB2 were not observed via x-ray diffraction (hereafter, XRD) analysis. The flexural strength, 306.23MPa of TP156 was higher than that, 279.42MPa of TP146 at room temperature, but lower than that, 392.30MPa of TP155. The properties of a SiC-ZrB2 composites through SPS under argon atmosphere were positive temperature coefficient resistance (hereafter, PTCR) in the range from 25℃ to 500℃, and V-I characteristics of them were linear because the slope of the V-I plot increased with temperature. The electrical resistivities of TP145, TP146, TP155 and TP156 were 6.75×10-4, 7.22×10-4, 6.17×10-4 and 6.71×10-4Ω?cm at 25℃, respectively. SiC-ZrB2 복합체는 β-SiC와 ZrB2의 혼합비율 60:40 vol.%로 혼합하여 방전플라즈마소결(SPS)법으로 제조 되었다. SPS조건은 소결온도와 일축가압을 변화시켰고, 1400℃-50MPa, 1400℃-60MPa, 1500℃-50MPa, 1500℃-60MPa에서 각각 소결한 TP145, TP146, TP155, TP156의 SiC-ZrB2 복합체의 물리적, 전기적 및 기계적 특성을 분석하였다. SiC-ZrB2 복합체(TP145, TP146, TP155, TP15)의 상대밀도는 각각 94.75%, 94.13%, 97.88%, 95.80% 이고, XRD 분석결과 β-SiC과 ZrB2 분말 간에 반응이 일어나지 않은 것으로 관찰되었다. 꺾임강도 392.30MPa의 TP155 복합체는 소결온도가 낮은 TP145 복합체 273.23MPa와 소결압력이 높은 TP156 복합체 306.23MPa 보다 높다. Argon 분위기에서 SPS를 통한 SiC-ZrB2 복합체는 25℃?500℃에서 PTCR(positive temperature coefficient resistance)특성을 나타냈으며, V-I특성은 SiC-ZrB2 복합체 모두 선형성을 나타났다. 전기저항률은 실온에서 각각 6.75×10-4, 7.22×10-4, 6.17×10-4, 6.711×10-4Ω?cm이다.

This study examined prevalence and related factors of musculoskeletal symptoms on whole body and four areas of necks, upper limbs, backs and legs of shipbuilding workers in order to prevent musculoskeletal disorder and find out its managerial plans. For the purpose, this study targeted 1159 male shipbuilding workers who work for large suipbuilding companies, and interviewed them using organized questionnaire having short answer questions in February, 2003. And the results were presented as follows: The prevalence of musculoskeletal symptoms(pains, anesthesia, and numbing) of the subjects was as follows: 16.0% on necks, 37.4% on upper limb, 26.1% on back, and 21.7% on legs, and 69.5% on whole body area. As a result of multiple logistic regression analysis, the following results were obtained: sleeping hours, working departments, extra working hours, perceived amount of working, availability of dispensary were significantly related with symptoms on necks; number and kinds of insurance taken out, sleeping hours, his or her companies, working period, working departments, extra working hours, perceived amount of working, working posture, Karasek classification, and availability of dispensary were related with symptoms in upper limb; The symptoms on back was related with age, sleeping hours, working departments, extra working hours, number of tools used by him or her, working posture, and availability of dispensary; and the legs were significantly related with sleeping hours, working period, extra working time, perceived amount of working, working posture, and availability of dispensary. When the variables that had significant relation with prevalence of whole body area symptoms were analysed demo-sociologically, it was found that the odds ratio of the group who took out more than two personal insurances was 2.36 times higher than that of the group who did not. When they were examined in terms of occupational characteristics, the odds ratio of the subcontract company workers was 0.28 times lower than that of the parent company workers, and that of the group whose working period was five and nine years was 1.94 times higher than that of the group whose working period was less than four years. In terms of working departments, the odds ratio of outfitting workers was 3.19 times higher than that of workers of painting department and that of fabrication workers was 2.56 times higher. The odds ratio of the group who had two hours of extra working hours was 2.04 times higher than that of the group who did not, and that of the group who had more than three hours of extra working hours was 3.75 times higher than that of the group who did not. The odds ratio of the group who used one kind of tool was 3.16 times higher, that of the group who used two kinds of tools was 6.61 times higher, that of the group who used three kinds of tools was 3.25 times, that of the group who used four kinds of tools was 5.11 times higher and that of the group who used five kinds of tools was 6.62 times significantly higher than that of the group who did not use any tool. The odds ratio of the group who thought the perceived working amount was slightly over the proper level was 1.66 time higher, and that of the group who thought it was excessively over the proper level was 3.32 times significantly higher. In terms of working posture, the odds ratio of the Group 4 was 2.78 times significantly higher that of Group 1. Socio-psychologically, the odds ratio of the group who had high degree of social support and tension was 3.13 times higher than that of the group who had high social support and low tension. And the odds ratio. In conclusion, it was found that 70% of shipbuilding workers had musculoskeletal symptoms, and their demo-sociological, occupational, and socio-psychological characteristics affected the symptoms. Therefore, to decrease musculoskeletal symptoms of shipbuilding workers, working condition should be improved by considering occupational characteristics of the workers. And it was concluded that socio-psychological approaches such as decrease of tension from working by enlarging the degree of social support through encouragement from senior and fellow workers, recognition of working ability, and improvement of self-esteem are important.

As electricity has been used in ship's propulsion, it is necessary to increase the system voltage and current for the electrical distribution system. So it is required to improve the system safety and efficiency, the power stability, the efficiency of the generation through various analysis of ship's electric power system. In this paper, the electrical service reliability of the power distribution system of Semi Submersible Drilling Rigs(SSDRs) has been analysed and discussed using Electrical Transient Analysis Program(ETAP). In the case of Semi Submersible Drill Rigs that are being used in most of the deepwater drilling operations, it can move by thrusters with Dynamic Positioning System(DPS), and has equipped a drilling packages like pumps, pipes and drills. The electrical distribution system of Drilling rigs is quite similar to typical redundancy system of electric propulsion ships made for transportation. However it is required the electrical distribution system of 2 to 4 split bus or more because of the severe marine environment, the hazards of fire and explosion, 24-hours operation, the standards and regulations related to oil and gas drilling. There are some more difficulties in design and engineering of the off-shore plants electric power system because it is required more severe and strict conditions. In this paper, to verify the stability of designed power system, the power system of SSDRs is modeled at first and load flow is analysed on each operational mode and also analysed on transient characteristics due to start/stop action between generators and loads. On the basis of the analysis the voltage variation in the distribution feeder is discussed. As a result, the load flow analysis shows the resonable result with appropriate load distribution and the capacity of generators and transformers are enough to feed the maximum load. The capacity of generators and transformers have an acceptable margin for future load and emergency load.
