Today, due to the global recession car sales have been decreased rapidly and auto makers are competing continuously to expand their market share. Automakers are struggling in order to secure competitive cost and quality through continuous cost reduction and quality innovation activities to win in the competition. In this situation, auto parts makers are trying to reinforce price competitiveness by reducing COPQ (Cost Of Poor Quality) in the mass production stages by securing the quality of components in advance from the design stage through DFSS (Design For Six Sigma) activities which is 6 sigma approach in the R&D field. However, auto parts makers have been undergone various confusion, feeling difficulties to get interrelationship among various activities. Thus, this study is going to suggest approach method for much more effective R&D activities by securing interrelationship between ISO/TS 16949 system established in the auto parts industry and DFSS activities.

개혁개방과 그에 따른 중국사회 변화에 대한 지아장커(賈樟柯) 영화의 시대적 해석

이강인(Lee, Kang-In)(李康仁) 대한중국학회 2019 중국학 Vol.68 No.-

After reform and opening up, China rapidly developed social conflict and economic differentiation along with economic development. Among other things, the gap between urban and rural areas due to the permit of ownership patterns and the gap between businesses has resulted in China s new conflict as its economic speed is commensurate with that of its economy. In particular, the entry from rural areas into urban areas caused a drastic change in the social hierarchy, resulting in economic disparity and thought-provoking conflicts along with urban and rural gaps. As these problems developed remarkably, many young Chinese directors videotaped the urban poor, the farmers and the wandering young, who had been marginalized. In particular, Ziazhangker was the director who deals with social and hierarchical conflicts internationally with deep reflection in this sense of question. He is conveying the meanings of them to us in his films, not to mention them seriously. 개혁개방이후 중국은 경제적 발전에 따라 사회적 갈등과 경제적 분화가 급속히 일어났다. 그 중에서도 소유형태의 허용으로 인한 도시와 농촌간의 격차, 기업 간의 격차 등이 생기면서 중국은 새로운 갈등문제가 경제속도에 상응하면서 발생하게 된 것이다. 특히 농촌에서의 도시로의 진입은 사회 계층구조에 급격한 변화를 발생시켜서 도농간의 격차와 함께 경제적 격차와 사고적 갈등을 일으키게 되었다. 이러한 문제들이 현저하게 발생하게 되자 많은 중국의 젊은 감독들이 그동안 소외되어 왔던 도시 빈민들, 농공민, 방황하는 젊은이들을 소재로 영상으로 담아내었다. 특히 이러한 문제의식에 깊이 있는 성찰로 사회적, 계층적 갈등문제를 국제적으로 다루고 있는 감독이 지아장커(賈樟柯) 감독이었다. 그는 그의 영화들 속에서 그 의미들을 우리들에게 심각하지 않으면서도 신랄하게 전달해주고 있다.

Background/Aims: We performed this study to investigate the efficacy and safety of one-week triple therapy consisted of ranitidine bismuth citrate (RBC), amoxicillin and clarithromycin in the treatment of H. pylori-related peptic ulcers. Methods: Fifty patients with peptic ulcer and H. pylori infection were randomly divided into two groups. One group was administered with RBC 400 mg, amoxicillin 1 g, clarithromycin 500 mg twice daily (RAC group). The other group was administered with or omeprazole 20 mg, amoxicillin 1 g, clarithromycin 500 mg twice daily (OAC group). Four weeks after eradication therapy, H. pylori status, ulcer healing, histological improvement and side effects were assessed. Results: In the RAC group, the eradication rate was 80% (20/25) in the intention-to-treat (ITT) analysis and 95.2% (20/21) in the per protocol (PP) analysis. In the OAC group, the eradication rates in the ITT and PP analysis were 76% (19/25) and 86.4% (19/22), respectively. Ulcer healing rate of the RAC group was 94.7% in the PP analysis. The grade of gastritis was improved after treatment. No significant side effects were noticed in both groups. Conclusions: One-week triple therapy of RBC, amoxicillin, clarithromycin is effective and well tolerated in eradicating H. pylori and healing peptic ulcers. The efficacy is comparable to one-week course of omeprazole-based triple therapy. (Korean J Gastroenterol 2001;37:412-417)

사무.서비스 산업의 린 경영 활동에 관한 사례 연구

이강인,이순산,Lee, Kang-In,Lee, Soon-San 한국벤처창업학회 2012 벤처창업연구 Vol.7 No.1

최근 탈공업화와 산업의 서비스화로 서비스산업 뿐만 아니라 제조업 등 2차 산업에 있어서의 서비스 비중은 나날이 커지고 있어 금융 및 서비스업 그리고 제조업의 사무 서비스부문의 경영혁신이 절실한 실정이다. 급변하는 경영환경에 적극적으로 대처하기 위해 기업들은 여러 가지 경영혁신 방법을 도입하고 있다. 특히, 우리나라의 경우에는 선진기업의 혁신활동에 대해서는 유행적으로 도입하여 적용하고 있는 실정이다. 이러한 측면에서 1990년대 중반부터 6시그마(Six Sigma)가 도입되어 10년 이상을 경영혁신활동의 대명사가 되어 활발하게 추진하여 왔다. 그러나 6시그마는 도입 초기의 기대에 미치지 못하고 있다는 지적과 최근 들어 한국기업이 금융시장의 불안, 경기 침체 및 중국 등 후발 국가로부터 많은 도전을 받고 있는 상황에서 '린(Lean)' 이라는 혁신활동이 국내에 소개되고, 도요타자동차의 성장으로 린의 모태인 도요타 생산방식(Toyota Production System, TPS)이 다시 각광을 받으면서 린에 대한 관심이 집중되고 있다. 본 연구에서는 우선 린 경영의 진화과정 및 특징의 기존 연구를 고찰하고 제조부문과 사무 서비스부문과의 차이점을 비교 연구하였다. 다음으로 우리나라 기업의 혁신 담당자를 대상으로 설문조사를 실시한 다음, 사무 서비스부문에서의 린 적용에 대한 실행 모델을 제시하고 적용하였다. 그 동안 제조부문에서는 린에 대한 성공사례도 많고 이와 관련된 연구 또한 많이 수행되어 왔다. 그러나 사무 서비스부문에서의 린 적용에 대한 연구는 아직 그 활용이 초기 단계로 관련 연구가 많지 않은 상태이며 실증연구는 거의 찾아보기 어려운 실정이다. 본 연구는 린 경영의 이론적 고찰을 바탕으로 린 경영의 성공요인을 도출하고 기업에서 실질적으로 린을 추진하고 있는 추진자들을 대상으로 실증 연구를 하였다. 이는 린 경영이 최근 우리나라에 도입되고 있는 상황에서 어느 정도 향도로서의 역할을 할 수 있을 것으로 판단한다. 본 연구는 린을 적용하고 있는 기업 또는 경쟁력 강화를 위해 새롭게 린 경영 도입을 검토하고 있는 기업 및 동 주제에 대한 연구자들에 대하여 사무 서비스부문에서 효율적이고 성공적인 린 경영 추진을 위한 올바른 방향을 제시했다는데 의의가 있다 하겠다. It is urgently requested to innovate the management process of business-service areas in all industry such as financial business, services and manufacturing because of recent business trend - de-manufacturing trend and the weight increment of service in all industries. Many enterprises introduce various management - innovation methodologies in order to meet the rapidly changing business environment. Especially in Korea, it is a vogue to introduce the innovation methodology of the advanced company's. According to this style, the six sigma has been introduced over 10 years since late 1990's and it has become a synonym of innovation indeed. But the result of six sigma introduction has not reached to the level of expectation in its beginning. And the "Lean" have been introduced in Korea in the situation of global financial crisis, economic slump and the pursuit of developing country such as China. Many Korea companies pay attention to the "Lean" innovation activity because the TPS(Toyota Production System) is the matrix of Lean and is the motive power of Toyota growth. In this study, it was analyzed for the evolution course, distinctive features and effects of Lean management and was examined for the difference of Lean management between manufacturing industry and business-service areas. From this results, the characteristics of Lean management in business-service was analyzed. After survey of innovation agent in Korea company, the Lean model of business-service Industry was developed and applied. This study will be worthy to show the right direction to the enterprises which are to apply lean methodologies, or the enterprises which examine lean management for competitive advantages or the peoples who research the same topics.

중국문학과 노벨문학상의 의미적 해석

이강인(Lee, Kang-In) 동북아시아문화학회 2013 동북아 문화연구 Vol.1 No.35

There was an event that not only created a huge wave in the Chinese literary ideology, especially in the history of the Chinese modern literature of the last century, but also caused a significant sensation around the world. It was none other than the receiving of the Nobel Prize in Literature by Gao Xingiian, which was followed by another wave a decade later of receiving of the Nobel Prize in Literature by Mo Yan. In some ways, it was the unprecedented event in the history of the Chinese literary ideology. It was truly a shocking event that Chinese people became the consecutive recipients of the world-renowned Nobel Prize in Literature. It raised a controversy that there were impure political intentions behind such receipts even though its significance should be placed on the receiving of the Nobel Prize in Literature itself. The reason was because the receiving of the Prize by the two writers, Gao Xingiian and Mo Yan, has different interpretative meanings even though the both are Chinese. Accordingly, the purpose of this study is to analyze the literary significance of their receiving of the Nobel Prize in Literary, as well as their respective literary works, and analyze their literary and political significances to reexamine the significance of the Nobel Prize in Literature.

Background/Aims: The incidence and prevalence of Crohn’s disease are increasing in Korea. However, the guidelines for the management of Crohn``s disease have not been established in Korea. In the current study we determined the difference in the treatment methods between physicians in Korea for Crohn’s disease. Methods: We retrospectively analyzed the use of medical and surgical treatment modalities in 92 patients with newly diagnosed Crohn``s disease. We compared the treatment strategies among 4 physicians at 3 different institutions. Results: Prednisone, 5-aminosalicylates, antibiotics, immunomodulators, infliximab, and surgery were prescribed or preformed in 64%, 92%, 24%, 35%, 9%, and 22% of the patients, respectively. The surgical procedures included 12 bowel resections and 8 fistulectomies. The prescription rates for 5-aminosalicylates, prednisone, antibiotics, and infliximab did not differ, but of the use of immunomodulators was significantly different between physicians (p=0.012). The mean interval between diagnosis and the start of immunomodulators was 14 months, and was not different between physicians. The median dosage of immunomodulators was 50 mg per day, and was not different between physicians. Conclusions: A difference in medical treatment strategies for Crohn’s disease between physicians exists in Korea. Specifically, there was a significant difference in the use of immunodulators between physicians. The development of treatment guidelines for Crohn’s disease, together with efforts to decrease the inter-physician difference for treating Crohn’s disease are needed. (Intest Res 2009;7:41-46)

Gastric ulcer bleeding in neonatal period, mainly in preterm newborn babies or in neonates treated in intensive care units, is relatively frequent, However the occurrence of significant gastric ulcer bleeding in healthy full term infants is unusual. We experienced a case of massive upper gastrointestinal (GI) bleeding in a 3-day-old healthy full term infant. Endoscopic examination confirmed the presence of gastric ulcerations. Treatment was initiated with transfusion and histamine 2 receptor antagonist, and the clinical signs resolved. Mother`s serum antibody to Helicobacter pylori (H. pylori) was positive. We collected stool of the patient including other 17 infants in the intensive care unit. A highly sensitive semi-nested PCR for H. pylori DNA was performed, but all infants including the patient revealed negative. H. pylori infection is not related with upper GI bleeding in healthy full term infants. In conclusion, the diagnosis of upper GI bleeding in infant can be easily made by means of pediatric endoscopy, which is a simple and a well tolerated examination.

Objectives: Aims were to evaluate foot deformity in patients with rheumatoid arthritis for its types, prevalence, and relation with duration of the disease. Methods: Inspection, measuring of hallux valgus and calcaneal angle and footprint were done on 256 feet of 128 patients with rheumatoid arthritis. Transverse (metatarsal) arch and longitudinal arch were evaluated by foot printings. Results: 1) The most common type of foot deformities was hallux valgus in 175 of 256 feet (68.4%). Depressed transverse arches were in 169(66.0%), toe deformities including claw toe, hammer toe, curl toe and mallet toe in 125(48.9%), calcaneal valgus in 87(34.0%), callus in 67(26.2%), pes planus in 37(14.5%), and bunion in 25(9.8%) of 256 feet. 2) Foot involvements as the initial manifestation were seen in 41(32.0%) of 128 patients with rheumatoid arthritis. A duration of rheumatoid arthritis over 10 years were seen in 37 of 128 patients. In this patients mean number of involved toes per foot was 2.78 which was not statistically significant increase compared to that of all patients, 2.23 (p-value>0.05). Even with absence of foot symptoms in 28 of 128 patient with rheumatoid arthritis, toe deformities were seen in 1.55 toes per foot. And prevalence of hallux valgus, pes planus, depressed transverse arch and calcaneal valgus were 58.9%, 10.7%, 51.8% and 39.3% respectively. Conclusions: Foot deformities in patients with rheumatoid arthritis were usually inevitable complication. Even in the patients who had no foot symptom, there were foot deformities. So, we think that physicians should pay attention to the foot in all rheumatoid arthritis.

Background/Aims: The diagnosis of small bowel stricture was made by operation. Capsule endoscopy has been useful for diagnosis of small bowel diseases but has limited value in cases with stricture. Double balloon endoscopy is the useful method to visualize the entire small bowel. The aims of this study are to evaluate the feasibility of double balloon endoscopy and to differentiate the endoscopic findings in patients with small bowel stricture. Methods: Between March 2004 and February 2007, fifteen consecutive patients were referred for the evaluation of small bowel stricture. Small bowel strictures were suspected in small bowel series and CT in eleven patients. Capsule endoscopies were performed in six patients and entrapped in three patients. Double balloon endoscopy (EN-450P5/20, Fujinon, Japan) was performed with midazolam (median 5 mg, range 5-10 mg) and meperidine (median 50 mg, range 50-100 mg). All lesions except one were found within 60 minutes. One patient had been excluded because of false-positive finding of capsule endoscopy. Clinical and endoscopic findings were compared between strictures of Crohn’s disease (group I, n=6) and those of other causes (group II, n=8). Results: Double balloon endoscpies were performed with good tolerance without side effect. Age, chief complaints, duration of symptom, and initial hemoglobin and serum albumin levels were not different between two groups. The proportion of male sex was higher in group I than group II (100%, 38%, respectively; p=0.031). The strictures below 0.5 cm in diameter were 83% in group I and 13% in group II (p=0.026). The arrangement of stricture in group I was more eccentric than that in group II (100%, 17%, respectively; p=0.015). The location of stricture, appearance of surrounding mucosa, associated ulcer, and ulcer margin were not different between two groups. Conclusions: Endoscopic differentiation using double balloon endoscopy can be made easily and safely in patients with small bowel stricture. The strictures of small bowel in patients with Crohn``s disease were narrower and more eccentric than thosein patients with other diseases. (Intest Res 2007;5:38-44)

The purpose of this research is to suggest the promotive directions of Quality Circle activity. Since 1975, variety of organizations in Korea have widely the implemented Quality Circle activities for their management systems. Today, Companies are facing the harsh realities of a competitive environment. This is no time for revolutionary change. Instead, Companies are instituting revolutionary change meant to have impact within a very short time frame. The Worker`s Quality Circle activity is, essentially, a trouble shooting oriented voluntary small group within their working place to improve the surroundings creatively. The industries have enthusiastically used Quality Circle activities and were influenced from them. The Quality Circle activities can be regarded as a kind of Knowledge Management where new knowledge is created and knowledge is shared in the economy. However, the academics were less interested in this subject, as a result, there were no systematic guidances for Quality Circle activities. Also, the government was less interested in these activities, as a result, there were no systematic policy making for Quality Circle activities. Thus, in this research, the promotive directions for Quality Circle activities were suggested which were based on the results of survey Questionnaires presented to promoters of the domestic companies. As a results of this research, to maximize the effect of TQM(Total Quality Management) in the nationwide, Quality Circle activity as a bottom-up management should be more expanded and revitalized.
