이철성 ( Lee Chul Sung ),김장현 ( Kim Janghyun ) 한국유통경영학회(구 한국유통정보학회) 2018 유통경영학회지 Vol.21 No.5

기존 전통시장에 대한 정부 정책은 대형유통업체와의 경쟁으로 인하여 전통시장의 매출감소를 방지하고 지역 경제의 기반을 유지하고 활성화시키기 위한 측면에서 이루어졌다. 그러나 대형유통업체는 SSM 및 상품공급점, 식자재 마트 등과 함께 최근에는 편의점을 통해 전통시장에 입점하고 있는 현실이다. 이러한 대형유통업체로 인한 전통시장잠식은 매출하락에 영향을 미치며, 장기적으로는 부동산 가치의 하락을 야기하여 전통시장이 사라질 수 있음을 의미한다. 그러나 소매경쟁의 측면에서 이에 대한 연구는 부족한 실정이다. 그러나 이에 대한 연구는 부족한 실정이다. 따라서 본 연구에서는 이철성, 김영기, 김승희(2018)과 김승희, 이철성, 김영기(2018)의 연구를 바탕으로 전통시장의 소매경쟁과 임대료의 관계를 살펴보려 한다. 이를 위하여 소상공인시장진흥공단과 한국감정원의 자료를 바탕으로 이들간의 관계를 실증분석하였다. 연구 결과는 다음과 같다. 첫째, 전통시장 내 SSM 및 상품공급점의 입점은 점포의 단위면적당 임대료를 낮추는 것으로 나타났다. 이러한 연구결과는 기존 김승희, 이철성, 김영기(2018)의 연구결과에서 이들 업체의 입점이 전통시장의 공실률에 부정적인 영향을 미친다는 결과와 일치한다. 둘째, 전통시장 내 하나로 마트의 입점은 점포 임대료에는 영향을 미치지는 것으로 나타났다. 이러한 연구결과는 하나로 마트가 유통산업발전법 제외 대상이나 실질적으로 대형유통업체로 간주해야 하며, 전통시장에 부정적인 영향을 미치고 있음을 의미한다. 마지막으로 전통시장 내 식자재 마트와 기타 마트의 입점은 점포 임대료에 영향을 미치지 않는 것으로 나타났다. The government policy on the traditional market has been made in order to prevent the decrease of sales in the traditional market due to competition with large retailers and to maintain and activate the foundation of local economy. However, large retailers have recently entered the traditional market through convenience stores, commodity supply stores, and food materials mart. Recently, it has been opened through convenience stores. Traditional market erosion caused by these large distributors affects sales decline, and in the long run, it may lead to a decline in real estate value and the traditional market may disappear. However, research on retail competition is lacking. Therefore, this study will examine the relationship between retail competition and rent in traditional markets based on the researches of Lee Chul-sung Kim Young ki, Kim Seung-hee (2018) and Kim Seung-hee, Lee Chul-sung and Kim Young-ki (2018). For this purpose, we conducted empirical analysis on the relationship between them based on the data of the market promotion corporation and the Korean appraisal agency. The results of the study are as follows. First, SSM and commodity supply store in traditional markets lower rent per unit area of stores. These findings are consistent with the findings of Kim Seung-hee, Lee Chul-sung, and Kim Young-ki (2018) that the entry of these firms negatively affects the vacancy rate of traditional markets. Second, Hanaro mart's entry has a negative effect on store rents. These results imply that Hanaro Mart should be regarded as a large-scale retailer or a target to be excluded from the retail industry development law and has a negative impact on the traditional market. Finally, it was found that the number of food materials mart and other mart in traditional markets did not affect store rents.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

This study was designed to investigate the position of anteroposterior center of resistance for genuine intrusion and the mode of change of the minimum distal force for simultanous intrusion and retraction of the upper and lower incisors according to the increase of labial inclination. For this purpose, we used the three-piece intrusion arch appliance and three-dimensional finite element models of upper and lower incisors. 1. Positions of the center of resistance in upper incisors according to the increase of the labial inclination were as follows; 1) In normal inclination situation, the center of resistance was located in 6mm behind the distal surface of the lateral incisor bracket. 2) In 10˚ increase of the labial inclination situation, the center of resistance was located in 9mm behind the distal surface of the lateral incisor bracket. 3) In 20˚ increase of the labial inclination situation, the center of resistance was located in 12m behind the distal surface of the lateral incisor bracket. 4) In 30˚ increase of the labial inclination situation, the center of resistance was located in 16m behind the distal surface of the lateral incisor bracket. 2. Positions of the center of resistance in lower incisors according to the increase of the labial inclination were as follows; 1) In normal inclination situation, the center of resistance was located in 10mm behind the distal surface of the lateral incisor bracket. 2) In 10˚ increase of the labial inclination situation, the center of resistance was located in 13mm behind the distal surface of the lateral incisor bracket. 3) In 20˚ increase of the labial inclination situation, the center of resistance was located in 15m behind the distal surface of the lateral incisor bracket. 4) In 30˚ increase of the labial inclination situation, the center of resistance was located in 18m behind the distal surface of the lateral incisor bracket. 3. The patterns of stress distribution were as follows; 1) There were even compressive stresses in and periodontal ligament when intrusion force was applied through determined center of resistance. 2) There were gradual increase of complexity in compressive stress distribution pattern with increase of the labial inclination when intrusion and retraction force were applied simultaneously. 4. With increase of the labial inclination of the upper and lower incisors, the position of the center of resistance moved posteriorly. And the distal force for pure intrusion was increased until 20˚ increase of the labial inclination.

김성용,남충현,주종우,채만규,백무준,이문수,김형철,안현철,김홍수,김창진,김창호 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.1

Purpose: Angiogenesis is important for the proliferation and the metastasis of solid tumors. The growth of a solid tumor is widely recognized to depend on the process of neovascularrozation. Without angiogenesis, tumors cease to grow beyond even a few milimeters in diameter. It has been shown that tumor vascular density is an independent prognostic marker in several types of human tumors and is known to correlate with poor prognosis. To date, many angiogenic factors have been identified, such as transforming growth factor-α(TGF-α), transforming growth factor-β(TGF-β), fibroblast growth factor family(FGF), vascular endothelial growth factor(VEGF), platelet derived endothelial cell growth factor(PD-ECGF), tumor necrosis factor-α(TNF-α), and angiogenin. Hepatocellular carcinoma(HCC) is the second most common tumor in Korean males and is known as a typical hypervascular tumor with frequent portal vein invastion. The authors identified the expreesion of VEGF, TGF-β1, and b-FGF in HCC specimens and evaluated the relationship between these growth factors and the clinicopathologic characteristics of HCC. Method: We reviewed the medical records of 30 patients who were diagnosed as hepatocellular carinoma treated with hepatic resection between January 1994 and December 1998 in Soonchunhyang University Chunan Hospital. The selection of the cases was decided according to the condition of paraffin block fixation. The prognostic factors such as age, sex, tumor size, concentration of serum α-fetoprotein, presence of liver cirrhosis, presence of tumor emboli in portal vein, TMN stage, amount of transfusion during the operation, hepatitis B virus(HBV) infection, and Edmonson-Steiner(E-S) grade were investigated. Relationship between the prognostic factors and the immunopathologic expression of the TGF-β1, b-FGF, and VEGF was examined. Result: Thirty patients (24 males, 6 females) were included in the current study. The patient's mean age was 50.6 years and the age ranged from 36 to 65 years. The mean size of the tumor was found to be 5.2cm. All the patients were follewed up for 7 to 63 months. Child's classification A patients were 23(76.7%)cases, B patients were 7(23.3%)cases, and C was none. Immunohistochemical staining of HCC tumor mass in VEGF expression patients were 17(56.7%), b-FGF expression patients were 10(33.3%), and TGF-β1 expression patients were 10(33.3%). VEGF expression or more than one positive expression among the three factors correlated with tumor size and the stage of HCC but did not correlated with other clinicopathological characteristics. TGF-β1 and b-FGF did not correlate with any clinicopathological characteristics. Conclusion: The results suggest that the expression of VEGF or more than one positive expression among the three factors in HCC cells may be a significant prognostic factor of HCC.

In mandibular tumor treatment case,mandibulectomy is frequently performed.This mandibulectomy may result in facial changes, esthetic and phonetic problems, reduced mastication and swallowing functions. When we treat this patients, using primary reconstruction with autogenous bine graft or secondary reconstruction with delayed bone graft after applied bridge plate removal. After bone graft is done, prosthodontic treatment is essential for the rehabilitation of facial esthetics, phonetics and mastications. But, tissue-supported prostheses have the problems of frequent breakdown of underlying bone anf soft tissue, increasing risk of intraoral infection, mobility of prostheses, unsatisfactory function, problems in esthetics, poor patient co-operation. Now, osseointegrated implants are used as the main treatment of fully or partially edentulois state of mandible, long term clinical data are satisfactory, too. So, we may choose the implant,as the useful prosthodontic treatment method of mandibular reconstruction using autogenous bone graft. Regardless of this harmful situation, as astivity(in malignant madibular tumor), and relatively poor condition of grafted bone, thoughtful treatment plan, delicate and technique, persistent follow-ups make much more satisfactory results than those of removable prostheses. So. we reported a good results in the case of implat-retained protheses after mandibulectomy and autogenous bone graft.
