이용규(Lee, Yong-Gyu) 한국경영교육학회 2020 경영교육연구 Vol.35 No.2

[연구목적] 본 연구는 상대적으로 연구가 부족했던 기업 간 거래관계에서 나타날 수 있는 상호의존성과 공급사슬통합 및 사회적 자본 간의 관계를 분석하는 것이다. 따라서 상호의존성이 공급사슬통합에 미치는 영향과 공급사슬통합이 사회적 자본에 미치는 영향을 실증하고 시사점을 제공하고자 하였다. [연구방법] 본 연구는 상호의존성, 공급사슬통합, 사회적 자본에 대한 선행연구들과 논의를 충분히 검토하였으며, 최종적으로 5개의 가설을 도출하였다. 국내 기업들을 대상으로 설문자료를 수집하였으며, 연구항목에 대한 신뢰성과 타당성을 분석하고 이를 충족하는 연구항목을 이용하여 Smart PLS 2.0을 활용하여 가설을 검정하였다. [연구결과] 연구가설의 검정결과 공급자 및 구매자 의존성은 공급자 통합과 구매자 통합에 유의한 정(+)의 영향을 미친다. 공급자 통합은 구조적, 관계적, 인지적 자본에 유의한 정(+)의 영향을 미친다. 구매자 통합은 구조적, 관계적 통합에 유의한 정(+)의 영향을 미친다. 또한 공급사슬통합은 매개변수의 역할을 하는 것으로 검정되었다. [연구의 시사점] 연구결과 거래기업들에 대한 필요성으로서 상호의존성 지각은 여러 거래기업들을 하나로 통합하는 공급사슬통합에 반드시 필요로 하는 요인이며, 나아가 공급사슬통합은 네트워크 자본으로서 사회적 자본의 형성과 구축에 영향을 미치는 것으로 나타나 개별기업들에게 공급사슬통합의 중요성에 대한 이론적, 실무적 시사점을 다시 한 번 제시하는 것이다. [Purpose] This study analyzes the relationship between interdependence, supply chain integration and social capital that can occur in the business relations between companies that have been relatively lacking in research. Therefore, this study attempts to demonstrate the effects of interdependence on supply chain integration and the effect of supply chain integration on social capital and to provide implications. [Methodology] This study thoroughly reviews previous studies and discussions on interdependence, supply chain integration, and social capital. Finally, five hypotheses were drawn. The survey data were collected from domestic companies, and the hypotheses were tested by using Smart PLS, using the research items that complied with the reliability and validity of the research items. [Findings] The hypothesis test shows that supplier and buyer dependencies have a significant positive effect on supplier integration and buyer integration. Supplier integration has a significant positive impact on structural, relational and cognitive capital. Buyer integration has a significant positive effect on structural relational integration. Supply chain integration has also been tested as a parameter. [Implications] As a result of the study, the perception of interdependence as a necessity for trading companies is a necessary factor for supply chain integration integrating several trading companies into one. It suggests to companies once again the theoretical and practical implications of the importance of supply chain integration.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

1996-1997년 겨울철에 유행한 인플루엔자의 임상역학적 분석 및 원인 바이러스의 분리

김수정,정규영,이용화,기창석,이남용,이상일,김지희 대한감염학회 1997 감염 Vol.29 No.4

목적: 인플루엔자는 매년 겨울 전 세계적인 유행을 일으키는 급성 호흡기 질환으로 높은 이환률과 사망율을 보인다. 국내에서도 1996-1997년 겨울철에 다수의 보고가 있었으나 아직 체계적인 감시가 이루어지고 있지 못하다. 저자들은 이 기간 동안 인플루엔자 바이러스 감염의 역학적 특성과 임상상을 연구하여 인플루엔자 감시의 기초 자료를 제공하고자 하였다. 방법: 1996년 10월부터 1997년 4월까지 삼성서울병원 임상병리과에 인플루엔자 바이러스 배양 검사가 의뢰된 모든 검체를 대상으로 인플루엔자 바이러스의 분리율과 유행 양상, 그리고 환자들의 임상상을 후향적으로 조사, 분석하였다. 결과: 총 461명의 환자로부터 525례의 검체가 의뢰되어 총 98명의 환자로부터 인플루엔자 바이러스가 분리되었다. 인플루엔자 A형은 54명의 소아 환자와 4명의 소아 환자로부터 분리되었다. 아형과 항원 특성 검사를 시행한 31례의 인플루엔자 A형 중 한 예에서 A/Wuhan/359/95 유사주로 확인되었고 12례의 인플루엔자 B형 중 5례에서 B/Guangdong/8/97 유사주로 확인되었다. 인플루엔자의 유행 양상은 3월과 4월 중순, 두 번의 인플루엔자 최고 분리 시점이 관찰되었고, 가장 많은 불리 빈도를 보인 연령층은 인플루엔자 A형의 경우 1세 미만이었고 인플루엔자 B형의 경우 3-5세였으며 폐렴이 가장 흔한 호흡기 질환이었다. 결론: 저자들은 3차 의료기관에서 분리된 인플루엔자 바이러스에 대한 역학적, 임상적 특성을 연구하였다. 지역사회에 대한 광범위한 연구가 아니므로 국내의 전반적 상황과는 차이가 있을 것으로 생각되지만 우리나라에서도 인플루엔자 바이러스의 이환률이 낮지 않을 것으로 생각되며, 보다 조직적이고 전국적인 인플루엔자 감시가 이루어져야 할 것으로 사료된다. Background: Although influenza has been a leading cause of global morbidity and mortality, we have few data regarding the epidemioloical and clinical characteristics of influenza activity in korea. Since an outbreak of influenza was recognized during winter of 1996-1997, we analysed the epidemiological and clinical features of influenza activity in the hospital seeting. Methods: All clinical specimens requested for isolation of influenza virus at Samsung Medical Center from October 1996 to April 1997 were included. Mardin-Darby canine kidney (MDCK) cell line was used for virus culture. Isolated viruses were confirmed with immunostain followed by subtyping. The demograpic and clinical characteristics of the patients were reviewed retrospectively. Results: Ninety eight influenza viruses were isolatd from 461 patients (21.3%). Influenza A and B virus were isolated from 58 (54 children and 4 adults) and 40 pediatric patients, respectively. One of 31 influenza A viruses was confirmed as A/Wuhan/359/95-like strain and 5 of 12 influenza B viruses were confiremd as B/Guangdong/8/97-like strains. Two distinctive peaks of influenza activity were recognized and the most common age of patients was less than 1 year for influenza A, and 3 to 5 years for influenza B. Common lower respiratory infections were pneumonia followed by croup, bronchiolitis and laryngitis. Conclusion: We analyzed the epidemiological and clinical features of influenza activity during winter of 1996-1997. Although this study was performed not in the community but in the hospital setting, the morbidity caused by influenza may not be low in Korea. Therefore, nationwide surveillance for influenza activity is warranted.

A discrete formulation of the optimum design structures is developed and methods of solution are presented. The design problem is the allocation of member sizes from catalog of commercially available sections within the working stress constraints, the buckling stress constraint and the displacement constraint. Multiple sets of static service loads are considered in the formulation. Constraints for optimization of truss structures is transformed into the constraint set of a successive binary programming problem. A computer program is developed for the implementation of the above formulations and algorithm. Example application include seven bar truss and ten bar truss.

Purpose : To measure the absorbed doses of cone beam computed tomography (CBCT), which is recently being more frequently used, and to compare them with those of panoramic radiography. Materials and Methods : To measure the absorbed doses of CBCT (PSR-9000N, Asahi Roentgen Ind. Co., Japan), we placed TLD chips on the skin regions above the parotid and thyroid glands, and on the dorsum of tongue in a dental head phantom. We used two image acquisition modes of the Dental and Panoramic modes of CBCT, which differed in the field of view. Also, panoramic radiographs (Auto IIIN, Asahi Roentgen Ind. Co., Japan) were taken to compare with the absorbed doses of CBCT. Result : In the Dental mode of CBCT, the absorbed doses of the parotid gland, dorsum of tongue, and thyroid gland were 3.53, 3.13, and 0.36 mGy, respectively. In the Panoramic mode of CBCT, they were 9.57, 9.15, and 0.85 mGy, respectively. The panoramic mode showed higher absorbed doses than those of the Dental mode. In the panoramic radiography, the absorbed doses of the parotid gland, dorsum of tongue, and thyroid gland were 1.21, 1.19, and 0.16 mGy, respectively. And they were about 1/3 of the Dental mode and 1/9 of the Panoramic mode of CBCT. Conclusion : Absorbed doses of CBCT are higher than those of panoramic radiography, and dependent upon the field of view.

李奎遠,李珍遠,梁昌容 全北大學校 1996 論文集 Vol.42 No.-

Fuzzy theory is useful in dealing with vagueness and ambiguities concerned with subjective judgement of human beings. In this research the optimization of the section area of truss structure has been tested by using fuzzy theory. The section area of member was chosen with design variable and the weight function of strucure was chosen with objective function. According to changing constraint conditions linearly with using fuzzy set, various optimum object functions will be obtained by feasible direction method. This algorithm was applied practically to the 10 bar truss structure and subsequently came to almost same value of objective function. Therefore this algorithm appers to be effective method of section area optimization. Accordingly, the optimization of truss structures which utilizes the results of this study can be helpful in economical design of truss stuctures.
