Even though hospitality industry of Mt. Kumgangsan is faced with contemporary growing heuristics and biases under uncertainty caused by unexpected military and political catastrophe, leisure-needs to meet rising demands from their constituents for more and better public administration services have been increasingly involved in running exclusively characteristic environment-friendly hotel business for their own Mt. Kumgangsan tourism development. Although Hyundai Asan has suffered from almost the same political and historical past as that of the Koreans with grave problems about political regime. Many have been known to be absolutely necessary for national reunification of south and north parts confronted by collapse, without making exclusive and monopoly profits from 2002 to 2052.

Korean board of directors were inside directors for the most part in the past days. The outside director has been introduced to improve the manager-monitoring capability of corporate boards of directors since the financial and currency crisis in Korea. it is the most conspicuous that the board directors was changed in the supervision and policy decision function of management. The outside director serve as components of board of directors with expert knowledge, experiences and potential power. But the korean commercial law is several problem concerning the outside director. The important thing that cause to come from problem of ownership structure and governance structure in their company. The competence of the general meeting of shareholders was decreased and Korean Commercial Law conceded the powerful executive competence to the board of directors. The major shareholders have possessed a great number of share and have made their exclusive governance structure in the company. The expectations for the independent director have never been higher than they are today in the U.S. and Korea. In Korea the role of corporate boards in corporation have been changed and the outside directors, and audit committee have been introduced, finding out the necessity to pay attention to the independence of outside directors from the management. it is necessary to change the recommendation system for outside director and introduce the limitation of liability and the business judgment rule for outside director. We must enforce the independence of the outside directors to promote the effectiveness of outside director. to do this, it is necessary that the board has no connections with that related director. and, listed companies must establish the nomination committee for outside director, to guarantee the objectiveness and fairness from the stage of recommendation. it must be compulsory to place the cumulative voting to represent the will of minority shareholder. and we must ensure the situation for outside director to fulfill his duty. to do this, it is needed to educate outside director properly, and publish outside director's activity. We know that the education of the own company business and providing information to outside directors are not sufficient. the attendance ratio of outside director in board meeting is very low, and the specialty of outside director is also low, because of the influence of the majority shareholder and manager in recommendation of the candidate outside director. In the study on improvement of the outside director, which is still on the improvement, as the lack the case study, the further will be needed in every part of the facets in the future.

In this paper, finite element analysis of a fine blanking process by a common mechanical press equipped with specifically designed and devised tools for manufacturing precision fine blanking parts in more economical manner than an expensive precision fine blanking press is conducted. New die and tools are tested to reveal their effects on the quality of fractured surface. Tensile test of standard sheet specimens are made to reveal the flow stress under the assumption that the material behaves like an isotropic material. Recursive and iterative method is applied to find out an appropriate flow stress curve which matches the finite-element predictions of the tensile test with the experiments. A three-dimensional rigid-plastic finite element method, which is more effective for shearing process simulation, is employed and a scheme of element deletion after element degradation based on the theory of ductile fracture is adopted to fracture the material. The comparison with emphasis on the fractured surface and plastically deformed region has shown that the predictions are in good agreement with the experiments from the qualitative or quantitative standpoints of view.

본 연구는 안경원에서 사용되는 자각식 굴절검사 장비인 시험테와 자동포롭터의 정확도를 알아보아 신뢰도를 평가하고자 하였으며 시험테와 자동포롭터를 완성된 안경과 비교하여 시력의 질적차이를 알아보고자 하였다. 시험렌즈의 마이너스 구면렌즈와 마이너스 원주렌즈의 도수를 실측하였으며 1매의 마이너스 구면렌즈와 1매의 마이너스 원주렌즈로 구성된 합성굴절계를 장입순서를 달리하여 얇은 렌즈의 합성굴절력 공식과 굴스트랜드의 합성굴절력 공식으로 계산된 굴절력을 실측한 굴절력과 상호비교 분석하였다. 자동포롭터의 마이너스 구면렌즈와 마이너스 원주렌즈의 도수를 실측하였으며 마이너스 구면굴절력과 마이너스 원주굴절력이 합성된 도수를 실측하여 입력한 굴절력과 실제로 장입된 굴절력 사이의 오차를 상호비교 분석하였다. 또한 시험테에 시험렌즈를 겹쳐 장입한 도수와 포롭터에 입력된 도수간에 오차의 정도를 비교해보았고 어느 검사법이 완성된 안경과 오차가 적은지 알아보기 위해 각각의 방법으로 교정시력을 검사하였고 Colenbrander's LogMAR score로 변환하여 시력의 질을 비교해보았다. 만20세~만50세 이하의 성인남녀 남30명, 여25명 총 110안을 대상으로 하였으며 자동포롭터, 시험렌즈 set, 완성된 안경에서 0.1이상~1.2이하의 교정시력을 갖는 근시 또는 근시성 복성난시인 자로, 시력에 영향을 끼칠 수 있는 내분비계 질환 및 기타 안질환이 없는 사람을 선정하였다. Lianyungang tiannuo의 시험렌즈set는 국제규격(ISO)의 굴절력 규격에 부합하였으나 Xingda의 시험렌즈set는 구면렌즈 2개가 규격에 부적합하였다. 구면렌즈가 시험테의 안쪽, 원주렌즈가 시험테의 바깥쪽에 장입된 경우 얇은 렌즈의 합성굴절력의 공식으로 계산된 원주굴절력이 음의 방향으로 가장 높게 나왔고 다음으로 실측된 원주굴절력, 굴스트랜드의 공식의 원주굴절력 순으로 높게 나왔다. 실측 원주굴절력과 얇은 렌즈의 합성굴절력 공식의 원주굴절력 오차는 C-6.00 D인 구간에서만 통계적으로 유의한 차이를 보였고, 실측 원주굴절력과 굴스트랜드 공식의 원주굴절력 오차는 C-4.00 D인 구간을 제외하고 통계적으로 유의한 차이를 보였다. 굴스트랜드 공식의 원주굴절력은 동일한 원주렌즈가 장입된 상태에서도 구면렌즈의 굴절력이 커질수록 낮아졌다. 얇은 렌즈의 합성굴절력 공식으로 계산된 구면굴절력과 굴스트랜드 공식으로 계산된 구면굴절력은 동일하였으며 Lianyungang tiannuo의 시험렌즈set를 실측한 구면굴절력은 얇은 렌즈의 합성굴절력의 구면굴절력과 굴스트랜드 공식의 구면굴절력보다 평균 -0.06 ±0.11 D만큼 음의 방향으로 높았고 Xingda의 시험렌즈set를 실측한 구면굴절력은 얇은 렌즈의 합성굴절력의 구면굴절력과 굴스트랜드 공식의 구면굴절력보다 평균 0.04 D ±0.09 D만큼 양의 방향으로 높았다. 원주렌즈가 시험테의 안쪽, 구면렌즈가 시험테의 바깥쪽에 장입되었을 때 구면굴절력의 크기는 평균적으로 얇은 렌즈의 합성굴절력, 실측값, 굴스트랜드공식 순으로 음의 방향으로 높게 나타났다. 실측 구면굴절력과 얇은 렌즈의 합성굴절력 공식으로 구한 구면굴절력의 오차는 구면굴절력이 증가함에 따라 유의하게 증가함을 보였으며 굴스트랜드 공식의 구면굴절력과는 원주굴절력 또한 통계적으로 유의하게 증가함을 보였다. 원주굴절력의 크기는 평균적으로 음의 방향으로 얇은 렌즈의 합성굴절력, 실측값, 굴스트랜드공식 순으로 높았으며 구면렌즈가 시험테의 안쪽, 원주렌즈가 시험테의 바깥쪽에 장입되었을 때보다는 적게 감소하였다. 얇은 렌즈의 합성굴절력에서 원주굴절력은 C -4.00 D인 구간을 제외하고 통계적으로 유의한 차이를 보였으며 굴스트랜드 공식의 원주굴절력은 C-2.00 D인 구간을 제외하고 통계적으로 유의한 차이를 보였다. 본 실험에서 Huvitz와 Viewm의 자동포롭터 구면굴절력은 -6.00 D부터 -0.125 D이상 음의 방향으로 낮은 차이를 나타내기 시작했다. 구면굴절력의 p value는 0.000로 통계적으로 유의한 차이를 보여 일정한 도수차를 보였고 원주굴절력 또한 Huvitz의 자동포롭터는 -6.00 D부터 -0.25 D이상 낮아졌고 p value는 0.002로 통계적으로 유의한 차이를 보였으며 Viewm의 자동포롭터는 -7.00 D부터 -0.25 D이상 낮아졌고 value는 0.002로 통계적으로 유의한 차이를 보였다. 자동포롭터는 구면렌즈 디스크가 안쪽에 장입된 구조로 구면굴절력의 오차는 보이지 않았으나 동일한 원주굴절력이 장입된 상태에서도 구면굴절력이 높아질수록 원주굴절력이 낮게 측정되었다. Lianyungang tiannuo의 시험렌즈set를 1매의 구면렌즈를 시험테의 안쪽, 1매의 원주렌즈를 시험테의 바깥쪽에 중첩하여 실측한 굴절력과 동일한 도수를 입력한 Huvitz의 자동포롭터의 굴절력을 비교하였을 때 총 30건 중 동일한 수치를 보인 경우 8건을 제외한 22건에서 자동포롭터의 원주굴절력이 시험테 보다 낮게 측정되었다. 앞선 실험을 바탕으로 동일한 도수가 장입된 시험테와 자동포롭터, 완성된 안경을 이용하여 교정시력을 측정하였고 교정시력을 Colenbrander's LogMAR score로 변환하여 시력의 질적평가를 수행한 결과 모든 경우 The present study was aimed to examine the accuracy and verify the reliability of a trial frame and auto phoroptor, which are used in subjective refraction test at an optician’s. Therefore, comparison was made between a trial frame and an auto phoroptor, and completed glasses to know the qualitative difference of their vision tests. For the test lenses, the power of minus spherical lenses and minus cylinder lenses were measured, respectively, and two lenses, one from each lenses, were equipped on a refractometer in different sequence. And then its refractive power was calculated based on the formula of composite refractive power of thin lens and Gullstrand’s lens and compared with the measured refractive power. Next, the same procedure was applied to the auto phoropter consisting of minus spherical lens and minus cylinder lens. The two lenses were also measured for their power of glasses to calculate the composite refractive power of those lenses and it was compared with the measured refractive power in order to know if there is difference between them. And then, the test lenses were applied to the trial frame and the power of glasses were measured to compare it with that entered in the phoroptor. To know which testing method (the trial frame and auto phoropter) has less distant power of glasses from that of the completed glasses, corrected vision was measured by each method. The measured visions were converted into Colenbrander‘s LogMAR scores and the quality of vision was compared. The test objects consisted of a total of 110 eyes from 30 males and 25 females in full age between 20 and 50. The participants had corrected vision in the range of 0.1~1.2 in a phoropter, test lenses and completed glasses. They didn’t have myopia (nearsightedness) or compound astigmatism with nearsightedness. Furthermore, they didn’t have endocrine disorders and other eye diseases that can affect vision. It was turned out that the test lens of Lianyungang Tiannuo Optical Instrument Co, Ltd conformed to ISO standard for refractive power standard, whereas 2 test lenses from Xingda Co. Ltd didn’t meet the criteria. When a spherical lens was placed inside the trial frame and a cylinder lens was positioned outside of it, cylinder refractive power, which was calculated using the formula of composite refractive power of the thin lens, was the highest in negative direction and followed by the measured cylinder refractive power and Gullstrand's formula. The error in cylinder refractive power between the actual measure and the formula of composite refractive power of the thin lens was statistically significant except in the section of C-4.00 D. Cylinder refractive power computed by Gullstrand's formula decreased as the refractive power of the spherical lens increased even when the same cylinder lenses were applied. The spherical refractive power turned out the same both when calculated by the compound refractive power formula of thin lens and Gullstrand's formula. The measured spherical refractive power of the set of test lenses (Lianyungang Tiannuo) was higher by -0.06 ±0.11 D in negative direction on average than that calculated by the formula of composite refractive power of the thin lens and Gullstarand's formula, respectively. In the meantime, the measured spherical refractive power of the set of test lenses (Xingda) was higher by 0.04 D ±0.09 D in positive direction than that calculated by the formula of composite refractive power of the thin lens and Gullstarand's formula, respectively. When a cylinder lens was placed inside the trial frame and a spherical lens was positioned outside of it, spherical refractive power turned out to be high in negative direction as the following order: calculated by the formula of composite refractive power of the thin lens, by actual measurement and by Gullstrand's formula. The difference in spherical refractive power between the actual measure and the formula of composite refractive power of the thin lens significantly increased as spherical refractive power increased while the difference of spherical refractive power between the actual measurement and Gullstrand's formula significantly increased as cylinder refractive power increased. On average, the magnitude of cylinder refractive power was high in negative direction in the order of the formula of composite refractive power of the thin lens, actual measurement and Gullstrand's formula. It decreased less than when a spherical cylinder lens was placed inside the trial frame and a cylinder lens was positioned outside of it. Looking into the composite refractive power of the thin lens, cylinder refractive power showed a statistically significant difference except in the section of C -4.00 D while that computed by Gullstrand's formula also revealed a statistically significant difference except in the section of C-2.00 D. In this experiment, the spherical refractive power of the auto phoropters (Huvitz Co., Ltd and Viewm Co., Ltd) began to decrease slightly by more than -0.125 D from -6.00 D, which was statistically significant at p value=0.000, and showed a certain difference in power of glasses. The cylinder refractive power of the auto phoropter (Huvitz Co., Ltd.) also decreased by more than -0.25 D from -6.00 D, which was statistically significant at p value=0.000 and that of the auto phoropter (Viewm Co., Ltd) decreased by more than -0.25 D from -7.00 D, too, which was statistically significant at p value=0.002. An auto phoropter has a spherical lens discs inside, so that no difference was observed in spherical refractive power. However, even when the same magnitude of cylinder refractive power was entered, cylinder refractive power decreased as spherical refractive power increased. Based on the results above, corrected vision was measured for the trial frame, the auto phoropter and the completed glasses, all of which the same power of glasses was applied to. The measured corrected visions were conv
