본 연구의 목적은 베트남 커피변경지역이 글로벌 가치사슬에 통합되는 과정에서 나타나는 가치의 전유 및 실현관계를 고찰하고, 공유가치창출에 대한 지속가능한 커피 글로벌 가치사슬의 의미를 분석하고자 한다. 최근 베트남의 대표적 커피 변경지역인 닥락성은 일반 커피생산의 착취적 가치사슬에서 인증 커피 생산에 따른 공유가치사슬로의 전환을 경험하였다. 이와 같은 전환은 글로벌 가치사슬에서 지역의 교섭력과 경쟁우위를 강화시킴으로써 지속적인 가치 창출을 수반할 수 있을 것으로 기대되었다. 그러나 실질적으로 농가, 중개인, 외국 가공업체와 같은 지역 이해관계자간 이윤 분배의 위계성이 더욱 심화되는 현상이 나타났다. 이와 같은 현상의 원인은 크게 두 가지 측면에서 나타났다. 첫째, 다국적기업, 중개인, 농가 간 전속관계의 형성은 이해관계자에게 안정적인 시장을 확보해 주었지만, 다국적 기업이 전속 커피 중개인을 통해 농가를 간접적으로 통제함으로써 이해관계자 간 위계가 더욱 심화되었다. 둘째, 공유가치창출의 명목으로 농가로 전가된 사회적 및 생태적 비용이 농가의 경제적 이윤 획득을 악화시킨 반면에 다국적기업으로의 비대칭적이고 위계적인 이윤 분배를 가져왔다. 그 결과, 닥락성에 보다 위계적이고 종속적인 글로벌 가치사슬이 형성되었다.

Background and Objectives : Allergic rhinitis is one of the most common diseases in the otorhinolaryngology area. in oriental clinic, Hyunggaeyungyo-tang(HYT) has been used as a primary prescription to treat allergic rhinitis. However, there have been no studies so far performed on the effect of this HYT use. The purpose of this study was find out therapeutic effects of its exclusive use on the rat with allergic rhinitis. Material and Methods : Thirty BALB/c mice were divided into three group : normal group(NOR), control group(CON) inoculated with allergic rhinitis and sample group(SAM) treated with the HYT extract after it was treated the same as the control group. Rats were sensitized intraperitoneally with ovalbumin solution 4times at intervals of 2 days. After that time, rats in SAM were administered by HYT to treat the inflammation. Results : 1. The number of eosinophil in SAM noticeably decreased than CON and this decrease had probability. The inhibition of eosinophil distribution. The infiltration of eosinophil in SAM noticeably decreased than CON. 2. The damaged mucosa as disruption of cilia in respiratory cell, vacant mucose secreting cell and infiltration of inflammation intricate cells in CON were increased than NOR, but SAM same as normal configuration. Decrease of icthing and sneezing intricate neurotransmitter (substance P). Decrease of angiogenesis intricate cytokine(MIP-2). 3. Transcription factor(NF-${\kappa}B$ p65) was decreased. 4. Transcription factor inhibitor(p-$I{\kappa}B$) was decreased. 5. Inflammation cytokine(iNOS) was decreased. Conclusion : The results suggest that HYT is significantly effective in the treatment of inflammation caused by allergic rhinitis through the suppression of NF-${\kappa}B$ activation and iNOS production.

This paper examines the trend of restructuring and direction of management response in the Large Purse Seine Fishery. The large-scale fishing industry is one of the most popular fishing areas in the coastal area, and it has been developed by providing exclusive supplies of many types of catchy fish, such as mackerel and horse mackerel through physical productivity in fleet operations. However, the Large Purse Seine Fishery has been declining in profitability due to the deterioration of the business environment since 2000. It is at a crossroads whether it will disappear or regenerate as it is. The Large Purse Seine Fishery's current problems are: firstly, the continued deterioration of the fishery business balance and worsening labor problems, secondly, insufficient freshness management and quality control after landing, and thirdly, import competition. The fourth is the intensification of the market competition, which is the evolution of fishing variability and the increase in the proportion of small fish. The fifth is the reduction of the operating fishing ground due to the suspension of mutual fishing in Korea and Japan. To address these problems and suggest management response directions for the survival of large-scale fishing businesses is as follows. First, a sustainable production system should be established through strengthening resource management and promoting international fisheries cooperation. Second, the profitability of fishing management should be improved by introducing a low-cost supplier system and securing a stable labor force. Third, we should improve the leading and quality control of catch, improve the high value-added value of catch through brand development, and secure competitive advantage with imported produce. Finally, the government should establish a cooperative system among private sector, government, and research institutes to push ahead with these tasks and strengthen the competitiveness of the front and rear industries.

본 연구는 세월호 사고 관련 법령 조항들을 분석함으로써 행정입법(위임입법)의 문제점을 밝히고자 하였다. 분석결과에 따르면, 수난구호법과 해운법은 행정입법을 통한 보완이 불가피하게 되어 있었다. 따라서 공무원들은 국회의 의결을 거치지 않고 하위 법령을 제정할 수 있었고, 이 하위 법령들의 한계가 세월호 사고의 제도적 배경이 되었다. 다시 말해 과도한 행정입법으로 인해 한국해양구조협회가 수난구호에 대해 독점적인 권한을 행사할 수 있었으며, 한국해양구조협회에 대한 운영 및 감독뿐만 아니라 안전운항 관리도 부실화될 수 있었다. 이로 말미암아 공무원과 관련 업계의 유착이 발생했고, 국민의 안전은 뒷전으로 밀리는 결과가 초래됐다. 따라서 국회의 전문성을 높여 과도한 행정입법을 지양해야 하며 이와 동시에 행정부 스스로의 자율통제 역시 강화해 나가야 함을 알 수 있다. 본 연구의 이론적 함의는 추상적이고 규범적으로만 논의되던 행정입법의 문제점과 통제의 필요성을 경험적으로 밝혔다는 점이며, 정책적 함의는 세월호 사고가 발생하게 된 제도적 배경을 밝히고 보완할 지점들을 제시했다는 점이다.

Objective: To evaluate the factors that affect torque control during anterior retraction when utilizing the C-retractor with a palatal miniplate as an exclusive source of anchorage without posterior appliances. Methods: The C-retractor was modeled using a 3-dimensional beam element (0.9-mm-diameter stainless-steel wire) attached to mesh bonding pads. Various vertical heights and 2 attachment positions for the lingual anterior retraction hooks (LARHs) were evaluated. A force of 200 g was applied from each side hook of the miniplate to the splinted segment of 6 or 8 anterior teeth. Results: During anterior retraction, an increase in the LARH vertical height increased the amount of lingual root torque and intrusion of the incisors. In particular, with increasing vertical height, the tooth displacement pattern changed from controlled tipping to bodily displacement and then to lingual root displacement. The effects were enhanced when the LARH was located between the central and lateral incisors, as compared to when the LARH was located between the lateral incisors and canines. Conclusions: Three-dimensional lingual anterior retraction of the 6 or 8 anterior teeth can be accomplished using the palatal miniplate as the only anchorage source. Using LARHs at different heights or positions affects the quality of torque and intrusion.

Joint financial network of Korea Financial Telecommunications and Clearings Institute, which is an essential facility with a natural monopoly, maintained its closedness as monopoly/public utility model, but it has evolved in the form of open banking in order to obtain domestic fintech competitiveness in the rapidly changing digital financial ecosystem such as the acceleration of Big Blur. In accordance with digital transformation strategy of financial institutions, various ICT companies are actively participating in the financial industries, which has been exclusive to banks, through the link technology called Open API. For this reason, there has been a significant change in the financial service supply chain in which ICT companies participate as users. The level of security in the financial service supply chain is determined based on the weakest part of the individual components according to the law of minimum. In addition, there is a perceived risk of personal information and financial information leakage among the main factors that affect users' intention to accept services, and appropriate protective measures against perceived security risks can be a catalyst, which increases the acceptance of open banking. Therefore, this is a study on factors affecting the introduction of open banking to achieve financial innovation by developing an open banking security control model for financial institutions, as a protective measures to user organizations, from the perspectives of cyber financial security and customer information protection, respectively, and surveying financial security experts. It is expected, from this study, that effective information protection measures will be derived to protect the rights and interests of financial customers and will help promote open banking.

Objective: The study aimed to evaluate sugarcane bagasse as roughage in lactating cow on feed intake, digestibility, ingestive behavior, milk production and composition, and microbial protein synthesis. Methods: Ten Girolando cows at initial body weight of $450{\pm}25.6kg$ and at $143.7{\pm}30.7days$ in milk were assigned in two $5{\times}5$ Latin square designs. Five 21-day experimental periods were adopted ($1^{\circ}$ to 14-day: diets adaptation period; $15^{\circ}$ to 21-day: data collection and sampling period). The diets consisted of four different levels of sugarcane bagasse (45%, 50%, 55%, and 60%) and a control diet, commonly adopted in the region, based on spineless cactus (25% sugarcane bagasse), formulated to meet 12 kg/d milk yield. Results: The dry matter (DM), organic matter (OM), and total digestible nutrients intakes and DM and OM digestibilities observed for 45% and 50% bagasse inclusion were similar to control diet, while that 55% and 60% bagasse inclusion were lower. Cows fed control diet, and bagasse diets of 45%, and 50% levels had the nutritional requirements attended, that guaranteed 12 kg/d of milk yield. The crude protein intake and digestibility of cows fed 45%, 50%, and 55% of bagasse inclusion were similar to control diet. The neutral detergent fiber (NDF) intake and digestibility differ for all bagasse diets related to control diet, while the non-fiber carbohydrates intake and digestibility for cows fed 45% of bagasse were similar for control diet. The intakes and digestibilities of nutrients decreased linearly in function of bagasse inclusion; NDF and indigestible NDF intakes did not vary. The ruminating time, feeding and rumination efficiency, microbial protein synthesis and milk yield decreased linearly with sugarcane bagasse inclusion. Conclusion: Sugarcane bagasse decreases milk production; however, its inclusion level in between 45% to 50% associated to concentrate could replace diets based on spineless cactus for crossbred dairy cow's producing 12 kg/d of milk.

Objectives : The incidence of allergic rhinitis has increased but treatment in most cases has only dealt with the symptoms. Medicine has been developed that shows fewer side effects. However, some side effects and the psychological stress over taking medicine has remained. There have been no studies so far performed on the effect of this Jeulminmilmae-tang's use, only. The purpose of this study was find out the therapeutic effects of its exclusive use on an Animal Model with Allergic Rhinitis. Methods : Thirty Sprague-Dawley rats were divided into three group : normal group, control group and sample group. To induce the allergic rhinitis in control group and sample group, rats were sensitized intraperitoneally with 0.1$\%$ ovalumin solution 3 times at intervals of 1 week. Then intranasal sensitization was performed by diffusing 0.1$\%$ ovalumin solution 3 times at intervals of 2 days. After that time, rats in the sample group were oral administration treated by Jeulminmilmae-tang for 28 days. Compared with the sample group, rats in the control group were oral administration treated by normal saline for 28 days. We observed changes in nasal mucosa and submucosa; also changes in the segment of neutrophil, eosinophil, Iympocyte and monocyte in blood. We used the statistical methods of student t-test(p 〈0.05). And we observed the changes of AST, ALT of three groups and used anova test statistically. Results : The segment of eosinophil was significantly decreased in treated group when compared with the control group(p 〈0.05). The segment of neutrophil. in blood were decreased in the treated group when compared with the control group but. that was not significant statistically(p 〈0.05). There were some regrowth of the cilium in the treated group. Histologic changes showed edema congestion and expantion of grandular cells in nasal submucosa and hypertrophy of epithelium ill nasal mucosa were decreased in treated group when compared with control group. Effects of Jeulminmilmae-tang on the liver function were also studies in rats. Treatment of Jeulminmilmae-tang did not affected on AST and ALT. Conclusions : The results may suggest that oral administration treatment using Jeulminmilmae-tang decreases the inflammatory response on an Animal Model with Allergic Rhinitis.

본 논문에서는 주기억장치 DBMS(main memory DBMS: MMDBMS)를 위한 동시성 제어 관리자의 설계 및 구현에 관하여 논의한다. MMDBMS는 디스크 기반 DBMS와는 달리 주기억장치 액세스만으로 데이터 검색 및 갱신을 수행하므로 전체 수행 비용 중 동시성 제어 관리자의 수행 비용이 차지하는 비중은 매우 크다. 따라서 효율적인 동시성 제어 관리자의 개발은 MMDBMS의 성능에 큰 영향을 미치게 된다. 본 연구에서 개발된 동시성 제어 관리자는 이단계 라킹 규약을 기반으로 하며, 다음과 같은 특징을 갖는다. 첫째, 락의 단위를 주기억장치의 물리적인 할당 단위인 파티션으로 설정함으로써 응용 분야의 특성 분석을 통하여 동시성과 락 관리 비용을 유연하게 조정할 수 있다. 둘째, 락에 관한 정보를 파티션 내부에서 직접 관리함으로써 락 관리 비용을 크게 줄일 수 있다. 셋째, 시스템 데이터의 물리적 일관성 유지를 위한 수단으로서 래치를 제공한다. 개발된 래치는 공유 모드와 배제 모드를 모두 지원하며, CPU 이용률의 극대화를 위하여 Bakery 알고리즘과 Unix의 세마포어 기능을 결합하는 방법을 사용한다. 넷째, 락에 의한 교착 상태의 해결을 위하여 락 대기 정보를 기반으로 시스템의 교착 상태 여부를 주기적으로 검출하는 기능을 제공한다. 본 논문에서는 트랜잭션 테이블의 상호배제, 인덱스 혹은 시스템 카탈로그의 상호 배제, 실시간 응용의 지원 등 실제 구현에서 발생하는 중요한 이슈들에 관해서도 이울러 논의한다.
