With the increasing market share of retailer brands, many authors have paid considerable attention to retailer brands. Before market liberalisation in 1996 in Korea, retailer brand market was led by the supermarket retailing format, although the first retailer brand product was developed by the department store format. In parallel with the entry of foreign multiple retailers, the retailer brand market has experienced rapid growth. Particularly, the expansion of Tesco UK with well-established retailing know-how into Korea has encouraged Tesco Korea to actively get involved in retailer brand program. As a result, Tesco Korea has led retailer brand market in the Korean marketplace. The research starts with the question of why Tesco Korea has achieved such a higher retailer brand share. Accordingly, this study is to explore how Tesco UK has transferred its own retailing knowledge into Tesco Korea, in terms of retailer brand program development. In order to explore why the retailer brand share of Tesco Korea is higher than that of its counterparts, the author adopted in-depth interview with prepared-questions and store observation as a research methodology. To examine working process as well as information flows within Tesco Korea and from UK to Korea, in-depth interview method is one of the most suitable research methodologies, because of the difficulty of quantifying information or data related to work flows. In addition, to increase the validity of information, the researcher had interviews with Tesco Korea supplier and store personnel. Based on these research techniques, this research explored how Tesco UK has influenced or advised Tesco Korea, particularly, from the point of view of knowledge transfer. Since the entry of Tesco UK into Korea as a joint-venture, the retailer brand market share of Tesco Korea has continuously increased. It would be expected that Tesco UK has helped Tesco Korea to settle down in the Korean market. During interviews with Tesco and a Tesco supplier, the researcher found that Tesco Korea has obviously taken an advantage of retailing know-how created by Tesco UK. Furthermore, the retailer brand development and handling process of Tesco Korea has been operated with the help of Tesco UK. This might mean that Tesco UK has directly or indirectly an impact on the improvement of Korean retailer brand development skills. As a mechanism to transfer retailing knowledge developed in the home market into the host market, one of the international retailers, Tesco UK has adopted many different ways such as annual meeting, trading meeting to import or export own retailer brand products, offering of operation manual developed by Tesco UK and buyer cooperation between Tesco UK and Korea, in order to share information. Through these communication techniques, the knowledge of Tesco UK has been transferred to Tesco Korea. This research accordingly suggests that retailer brand market share is apparently related to how sophisticated or advanced the knowledge of the retailer brand development and handling process of retailers are. It is also demonstrated by this research that advanced development and handling skills make a considerable contribution to increasing retailer brand share in markets with a lower share or no presence of retailer brands.

본 연구에서는 한국 제조업의 노동소득분배율 변동요인을 1991-2009년 18개 산업 패널자료를 이용해 신고전파 경제학적 접근과 칼레키-포스트케인지안-정치경제학적 접근을 통합한 분석모형을 구축하고 실증 분석하였다. 분석결과, 수출과 수입 등 무역의 존도의 증가는 노동소득분배율을 높이고, 노동조합 조직률의 하락, 자본증진적 기술진보, 생산의 세계화가 노동소득분배율을 하락시킨 것으로 나타났다. 1997년 IMF 경제위기 이후 제도변화의 영향으로는 노동시장의 유연화와 노동조합의 고용규제력 약화로 노조조직률은 노동소득분배율에 영향을 미치지 못한 반면 외주비율 확대가 노동소득분배율을 하락시켰으며, 수출의 노동소득분배율 개선효과가 감소하여 낙수효과가 약화된 것으로 나타났다. 그밖에 주주 권한을 강화하는 기업지배구조 개편이 노동소득분배율을 하락시킨다는 포스트케인지안의 금융화 명제를 뒷받침하는 증거는 발견되지 않았다.

A method of conflict detection and resolution is described by using simple geometric approach. Two VAVs are dealt with and considered as point masses with constant velocity. This paper discusses en route aircraft which are assumed to be linked by real time data bases like ADS-B. With this data base, all DAVs share the information each other. Calculating PCA (Point of Closest Approach), we can evaluate the worst conflict condition between two VAVs. This paper proposes one resolution maneuvering logic, which can be called 'Vector Sharing Resolution'. In case of conflict, using miss distance vector in PCA, we can decide the directions for two VAVs to share the conflict region. With these directions, VAVs are going to maneuver cooperatively. First of all, this paper describes some '2-D' conflict scenarios and then extends to '3-D' conflict scenarios.

As internet streaming data increase, transport protocol such as TCP, TGP-Friendly is important to study control transmission rate and share of Internet bandwidth. In this paper, we propose a TCP-Friendly protocol using Neural Network for media delivery over wired Internet which has various traffic size(PTFRC). PTFRC can effectively send streaming data when occur congestion and predict one-step ahead round trip time and packet loss rate. A multi-layer perceptron structure is used as the prediction model, and the Levenberg-Marquardt algorithm is used as a traning algorithm. The performance of the PTFRC was evaluated by the share of Bandwidth and packet loss rate with various protocols.

In accordance with huge demand for capital to meet the expansion of steel production, there are more and more steel companies who have officially listed their stocks in HOSE and HNX. One of the key issues in successful initial public offerings and seasonal offerings for these companies is how to make stocks of steel companies become more attractive in the eyes of investors. The purpose of this research is to analyze the determinants of share prices of listed steel companies in Vietnam. This study utilized macro-economic variables, ratios and indicators representing characteristics of steel industry collected from Quarter 1/2006 to Quarter 4/2019 in association with the panel data and the feasible generalized least square (FGLS) model to evaluate the degree of these factors on the share prices. The results of the research show that ROE, Cons_rate, and CO2_rate are three main factors affecting the share prices of listed steel companies. Among which, ROE and Cons_rate have a positive effect, while CO2_rate has a negative effect on the share prices of listed steel companies. It also confirms the relationship between the environmental factor, construction industry factor and the stock prices. This lays foundations for recommendations for the future policies towards environmental protection and sustainable development.

본 연구는 2004년부터 2008년까지 8년간 국내 제약 기업들을 대상으로 소유 집중도가 기업의 연구개발투자에 미치는 영향을 실증적으로 분석한다. 특히 소유 경영 체제 또는 전문 경영 체제가 소유 집중도와 연구개발투자 간의 관계에 미치는 영향을 분석한다. 분석 결과 최대주주 지분율과 연구개발투자는 역 U자 형태의 상관관계가 있으며, 소유 또는 전문 경영 체제 여부는 역 U자 관계의 강도에 영향을 주는 것으로 나타났다. 즉, 전문 경영 체제하에서는 소유 집중도가 낮을 경우 소유 집중도의 추가적인 증가는 대리인 비용을 줄여 연구개발투자를 소유 경영 체제하에서 보다 더 크게 증가시키지만, 소유 집중도가 높을 경우 소유 집중도의 추가적인 증가는 지나친 위험 노출 증가에 대한 고려로 연구개발투자를 소유 경영 체제하에서 보다 더 빠르게 감소시킨다.

Korea ranks high among the OECD member countries with a high out-of-pocket share. In 2006, the government implemented in full scale the policy of extending the health insurance benefit coverage. Included in the policy are lowering the out-of-pocket share of patients of serious case and expanding the medical bill ceiling system to mention just a few. This study proposes to confirm effectiveness of the benefit extension policy by identifying changes in 'out-of-pocket expenditure as a share of the ability to pay' and 'incidence rate of catastrophic health care expenditure' of each individual household as manifested before and after the benefit extension policy was implemented. The 1st and 3rd year data from the Korea Welfare Panel Study (KoWePS), conducted by the Korea Institute for Health and Social Affairs (KIHASA), were used for the analysis, where low-income households and ordinary households are sampled separately. While the absolute amount of 'out-of-pocket expenditure' occurred to the average household increased for the period 2005-2007, the 'out-of-pocket expenditure as a share of the ability to pay' decreased. At the same time, the share decreased in the case of low-income households and households with patients of chronic or serious case as contrasted with ordinary households. 'Incidence rates of catastrophic health care expenditure' of ordinary households for 2007 stood at 14.6%, 5.9% and 2.8% at the threshold of 10%, 20% and 30%, respectively. The rates decreased overall between 2005 and 2007, while those of low-income households with patients of serious case statistically significantly increased. An analysis of this study indicates that it is related with the medical bill ceiling system regardless of incomes introduced in 2007.

Purpose - The purpose of this study is to analyze the effect of investment by the National Pension Service, which has a high share as a single fund, on the dividend payout ratio. Design/methodology/approach - This study secured a share through DART of the Financial Supervisory Service and disclosure of the National Pension Service. We also used a fixed-effects model and 2SLS to analyze the data. Findings - First, it was found that there was a possibility of conflicting interests among shareholders concerning the company's dividend payment policy. Second, in the range of 3% to 4.9% of the National Pension Service shareholding, an additional increase in the holding ratio was found to have a positive (+) effect on the dividend rate. Third, after the introduction of the Stewardship Code, it was found that the increase in ownership of the fund had a positive (+) effect on the company's dividend payout ratio, regardless of the share ratio range. Moreover, the relationship between the fund ownership and the dividend payout ratio showed a clear positive relationship when free cash flow was high along investment opportunities were low. Research implications or Originality - First, This study included less than 5% of the share in the analysis. Second, We used the recent changes in fund shareholder activities. Third, We tested an instrumental variable to confirm the relationship between the National Pension Service share and the dividend ratio.
