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)
자회사의 지식창출 활동 결정 요인에 관한 연구 : 다국적기업의 한국 내 자회사 사례를 중심으로
이강문(Kangmun Lee),조동성(Dong-Sung Cho),이윤철(Yun-Cheol Lee) 한국전략경영학회 2010 전략경영연구 Vol.13 No.3
지식기반 관점에서 다국적기업의 자회사들은 자신이 창출한 지식을 본사 및 동료자회사들에게 이전함으로써 다국적기업의 경쟁우위 향상에 기여한다. 자회사의 지식 이전 활동은 자회사가 현지 시장내 재무적 성과 창출과 같은 기능적인 역할 수행을 넘어서 전략적 리더의 역할로 진화하는 과정에서 나타날 수 있다. 따라서 자회사 역할 진화의 결과물인 자회사 지식이전 활동에 대한 학술적 접근이 활발하게 이루어졌다. 그러나 상대적으로 자회사 역할 진화의 요인이 되는 자회사의 혁신 혹은 지식창출 활동에 대한 논의는 다루어지지 못한 것이 사실이다. 따라서 본 연구는 특정 자회사의 지식창출활동에 대한 추가적인 연구를 주요한 목표로 하고 있으며, 자회사 지식 창출에 관한 기존 변수인 자회사의 조직적 속성과 현지 환경적 속성과 함께 자회사가 다국적기업의 네트워크와 맺고 있는 관계의 속성이 자회사의 지식창출활동에 미치는 영향에 대해 분석을 시도하였다. 구체적으로 본 연구는 조직적 속성인 기업가 정신, 관계적 속성인 의사결정에 대한 자율성, 사회적 자본 및 다국적기업 네트워크내 자회사의 영향력 각각이 자회사의 지식 창출에 긍정적 효과를 미치는 것과 현지 환경적 속성으로 현지경쟁강도의 부정적 효과를 국내에 진출한 다국적기업 자회사의 설문자료를 통하여 통계적으로 실증하였다. In Knowledge-based view, the subsidiaries of MNC are able to contribute to improve MNC's competitiveness by transferring their self-creating knowledge. They share their knowledge with parent and peer subsidiaries. It means that the role of subsidiaries evolves from 'implementor' to 'strategic leader'. Therefore, many studies have focused on subsidiary's knowledge transferring. However, the discussions about subsidiary’s knowledge creation, which is the sufficient condition for the evolution of subsidiary’s role, are insufficient. This study investigates the effects of subsidiary's local environmental and organizational characteristics on subsidiary’s knowledge creation and especially adopts three relational factors between subsidiary and other MNC’s organizations that affect on its knowledge creation. We introduced 'subsidiary's autonomy', 'subsidiary's social capital in a MNC network', and 'strength of subsidiary in a MNC network' as the subsidiary's relational factors and investigated the effect of three factors on subsidiary knowledge creation. The results showed that subsidiary's entrepreneurship as an organizational factor has a positive effect on subsidiary's knowledge creation but the level of local competition as an local environmental factor has a negative effect on it. Especially, three relational factors (autonomy, social capital, and strength of subsidiary in a MNC network) all positively related to subsidiary’s knowledge creation.

본 연구는 신체중심의 위치에 따른 겨룸새 형태에 따라 돌려차기가 어떻게 달라지는지 비교, 분석하여 겨루기 지도와 기술 향상에 필요한 자료를 제공하는데 본 연구의 목적이 있다. 이를 위해 태권도 겨룸새에 있어서 신체 중심을 기저면의 중앙과 전방에 위치시킨 두 가지 형태로 구분하고, 차기는 각 겨룸새 형태에서 제자리 돌려차기와 두 발 물러딛기 후(이동) 돌려차기로 구분하여 국가대표 급 남자 태권도 선수 14명을 대상으로 실시하였다. 또한 250Hz/sec로 설정한 7대의 카메라를 이용하여 동작을 획득하였으며, 수집된 Raw Data를 이용, 산출된 운동학적 변인들을 분석하였다. 수행시간, 신체중심의 이동 및 속도, 각 분절의 속도를 분석하여 다음과 같은 결과를 얻었다. 첫째, 차기의 전체 소요시간은 제자리의 전방형과 이동의 중앙형이 빨랐다. 둘째, 신체중심이동에서 제자리 전방형이 중앙형보다 목표물 쪽으로 더 많은 이동을 하였으며 신체중심 속도에서 제자리는 전방형이 이동은 중앙형이 빠른 속도를 보였다. 셋째, 다리분절의 각각의 속도를 비교한 결과 넙다리를 제외하고 두 겨룸새 사이의 차이는 없었다. The purpose of this study is to provide the requisite materials for improvement of Gyeorugi coaching and skills by means of comparative analysis on how spin kick changes according to Gyeorumsai form. In order to do this research, whose subjects are 14 national-level male Taekwondo athletes, central body axis is divided into the central and frontal one and Chagi technique is divided into standing spin kick and two-feet back stepping one. For image analysis, seven Cameras set in 250Hz/sec were used to capture their movement and kinematics variables calculated by the collected Raw Date were analyzed. As the factors of analysis, the conducting time, the movement and speed of the body centroid, speed of each segment, it gained the following results. First, with regard to the total consuming time for the kick, the frontal standing position wasfaster than the central one, and at the movement. Second, about the moving distance of the body centroid, the frontal standing position moved more to the object than the central one did. In terms of the speed of the body centroid, the frontal standing position was faster than the central one, and at the movement, it was found that the central type was speedier than the frontal one. Third, the foot segment indicated no great change in its speed between two Gyeorumsai forms except for thai.

This study examines antecedent factors that influence subsidiaries` MNC (multinational corporation) knowledge adoption. I argue that subsidiary local environmental factors(local embeddedness, level of local competition), subsidiary organizational factors(parent investment, subsidiary CEO expatriation, scope of subsidiary value chain), and subsidiary relational factors(subsidiary autonomy, the strength of subsidiary in MNC, social capital) are the important enablers for subsidiaries to adopt knowledge from other MNC units. Especially, I use two data set (knowledge from ① peer subsidiaries, ② parent company) to estimate the effect of the factors. The results indicate that subsidiary local embeddedness and scope of subsidiary value chain negatively influence on subsidiary knowledge adoption from peer subsidiaries. Conversely, the strength of subsidiary in MNC and social capital positively influence on that. Subsidiary knowledge adoption from parent company is positively influenced by parent investment and social capital.
기업가 정신이 자회사 지식창출에 미치는 영향에 관한 실증연구

The knowledge-sharing activities of subsidiaries are expressed as knowledge reverse transfers, and the subsidiaries that contribute to the enhancement of the capabilities of multinational corporations in terms of knowledge are called centers of excellence (CoE). Moreover, we focus on active tendency as a proactive factor while prior studies have been conducted on knowledge accumulation and creation of subsidiaries as a passive role of subsidiaries. In this study, we focus on the entrepreneurial spirit of subsidiaries as the core of proactiveness. The attributes of subsidiaries are located at the bottom of the head office in the organizational structure and tend to be dependent on the head office. However, this study aims at statistically verifying the causal relationship between entrepreneurship and knowledge creation of subsidiaries. In addition, we examine the antecedents that may affect entrepreneurship to differentiate this study from previous studies. A total of 282 foreign companies with subsidiaries in Korea were selected as a sample and analyzed using the Structural Equation Method. Empirical results show that the degree of product autonomy and vision sharing of subsidiaries have a positive effect on entrepreneurship, and the effect of this has a positive effect on subsidiary company knowledge creation. On the other hand, market autonomy and influence of the subsidiaries’s position did not seem to have any effect on entrepreneurship.

Nutrition, as a definite environmental factor, has been implicated in the pathogenesis of inflammatory bowel disease (IBD). Although low-fiber, high-sugar, and high-animal fat diets have been proposed as a risk factor, the role of nutrition in IBD still needs more conclusive evidence. Nutritional deficiency is a common problem in IBD patients. The goals of nutritional intervention are the prevention and correction of malnutrition, the prevention of osteoporosis, and the promotion of optimal growth and development in childhood. Enteral nutrition is effective in induction and maintenance of the clinical remission in adults and promoting growth in children with Crohn`s disease. The n-3 polyunsaturated fatty acids contained in fish oil may provide short-term benefit to patients with IBD. (Korean J Gastroenterol 2008;52:1-8)
