부산지역을 중심으로 한 수산물의 유통구조는 많은 변화를 보이고 있다. 1997년 자유 판매제의 전면 실시 이후 산지 수협을 중심으로 하는 "계통판매" 물량은 2001년을 제외한 2000년 이후는 위판량과 위판금액의 계통판매 비율이 계속 감소하여 2005년에는 물량 면에서는 54.7%, 금액 면에서는 53.2%까지 떨어지고 있다. 특히 단순한 위판기능을 필요로 하지 않는 양식수산물의 경우는 2005년도 기준 양식생산물 생산량의 73.8%, 생산 금액의 80.7%가 비계통판매이다. 또한 2006년도 부산수산물의 유통주체별 판매 점유율 중 대형할인점(백화점 포함)이 전체의 15%인 1,400억원(100,000톤)을 차지하고 있지만, 이 대형할인점의 판매비중은 매년 10%이상 크게 증가하고 있는 추세다. 따라서 급증하는 대형할인점의 수산물 유통시스템을 개선할 필요성이 있다. 이를 위해 대형할인점의 수산물 유통을 효율화하기 위한 수산정책 및 대형할인점에서 주로 판매되고 있는 냉동냉장 선어물의 보관시설 확충의 필요성이 증대하고 있으며, 수산물 가격 결정의 주도권이 소비지 도매시장에서 대형유통업체로 전환되고 있음을 감안하여 이에 부응하는 유통시스템 개선의 필요성도 증대되고 있다. 특히 대형할인점이 소비지 유통시장을 거치지 않고 생산지에서 직접 구매하여 판매경로를 단축시킴으로써 유통마진을 줄여 저렴한 가격에 소비자에게 수산물을 판매하는 형태는 시사하는 바가 크다.

Currently, Korea is actually increasing and increasing demand for leisure such as parts for A/S of automobile parts of the car, as well as trends in borrowing and finished parts are also required a steady increase in automobile traffic daetsu. There is one car and want to be driving a car A/S parts supplier smoothly for many years and that it is often the case if it is not supplied in a timely fashion, it is a reality that many eonseong hear from customers. These symptoms can be confirmed that the logistics systems of a system of selling auto parts supplier but above all a problem for several reasons, which will be considered as areas for improvement should be done urgently. Enterprises internally cooperation automotive supplier, but the need to get out to re-examine urgently complemented by the logistics system of systems to allow better respond to complex environmental changes of our customers grow, and now also the proliferation of small ship-run screen and Darvin, there is increasing distribution and logistics services, including logistics costs as a lack of work force that the company is itgetda can be called by the reality that the chances of getting a lot of jeyakreul own growth. Given this situation, the procurement of logistics enterprises. In-house logistics. Classified as sales logistics examined the long-term improvement of logistics distribution networks based on this part to derive into the problems of logistics and parts distribution system of Korean auto parts dealer.

Purpose - This study involves the following questions: "Does internalization theory fully explain reality?" and "Which additional factors may add extra value to the theory?" To answer these, this study divides market entry mode into two steps, initial and subsequent and then, focuses on the subsequent distribution step; that is, the post-entry strategy after initial entry. In addition, this study relies on finding strategic orientations that affect the decision of post-entry into foreign markets. Research design, data, and methodology - To investigate this, this study examines 252 cases of Korean online games for each foreign market and the distribution mode at the product-team level. Results - The result shows that companies use different distribution strategies as a post-entry mode, like licensing, or joint distribution rather than exclusive distribution, through subsidiaries even if they already have wholly owned local subsidiaries which have enough experience and resources to select the entry modes among various types and then provide full commitment and control. Additionally, it finds that strategic orientation affects post-entry strategies differently. Conclusions - Therefore, this study is noteworthy and significant, as it practically extends the existing theories such as an internalization and distribution for decision making regarding the overseas expansion of entertainment businesses.

본 논문에서는 효과적인 마커기반의 증강현실 구현을 위하여 영상 내 객체의 분포에 대한 분석과 반복 패턴을 포함하는 영상의 분류를 통한 마커영상의 평가 방법을 제안한다. 객체의 분포는 영상의 부분적 가림 현상에 따라 객체추적성능에 영향을 미치기 때문에 특징점 좌표의 분산을 이용하여 가림 현상에 취약한 마커영상을 구분할 수 있도록 하였고, 일반 영상과 반복 패턴을 포함하는 영상의 특징점 기술자 벡터의 분포가 현저하게 다르다는 사실에 기반하여 객체의 인식 및 추적에 적합한 영상을 구분할 수 있는 방법을 제안한다. 다양한 실험 결과 제안하는 마커 평가 방법이 가림 현상에 취약한 영상 및 반복 패턴 영상을 구분하는데 우수한 성능을 보이는 것을 확인하였다. 또한 마커영상에 대한 객체 추적 등의 안정성 측면에서 SURF보다 SIFT 기법이 우수한 성능을 보임을 확인할 수 있었다. 이러한 결과를 이용하여 다양한 종류의 마커영상에 대한 적합성 정보를 사용자에게 제공함으로써 효과적인 증강현실 시스템을 구현할 수 있을 것으로 판단된다.

Purpose - This study examines the changes in the mobile MMORPG market in recent years and the factors affecting the performance of mobile games through flow experience according to the characteristics of game content. Research design, data, and methodology - This study focuses on the fact that the cause of game use behavior changes is the flow experience which influences the duration of mobile game continuation. The flow experience and the influencing factors are divided into the relationship between first, second-leading factors, and lagged factors. Results - The user's sense of challenge, skillfulness, concentration, and reality influenced the flow experience as a leading factor influencing the performance of MMORPG games. On the other hand, fun and preference were found to be the outcomes of the flow experience. This is because the game content is experienced not through passive enjoyment but by intentionally enjoying the game content. The flow experience has a positive effect on the intention of continuous use as in the previous study. Conclusions - This study found that the flow experience of game users is necessary for continuous use by organizing relationships of flow experience in mobile MMORPG users' gaming behavior.

We frequently use Tukey's boxplot to identify outliers in the batch of observations of the continuous variable. In doing so, we implicitly assume that the underlying distribution belongs to the family of normal distributions. Such a practice of data handling is often superficial and improper, since in reality too many variables manifest the skewness. In this short paper, we build a modified boxplot and set the outlier identification procedure by assuming that the observations are generated from the skew normal distribution (Azzalini, 1985), which is an extension of the normal distribution. Statistical performance of the proposed procedure is examined with simulated datasets.

A method of calculation of temperature distribution during welding was studied and compared with the existing formulas and experimental results. In contrast to the existing formulas which are founded on the suppositions that the heat source is a point and that the dimensions of welded pieces are infinite, we tried to make the distribution of calorific density of heat source approach reality more closely, so we considered it as a normal distribution of Gauss, and we presented the formulas for calculation of temperature during welding. We also used the principle of superposition for the temperature calculations of finite welded pieces. We compared the formulas presented in this paper with the existing formulas by calculations for the welding of various materials, and considerable differences around the heat source were convinced. The thermal cycles of various points were traced through the welding experiments for the mild steel, and they were compared with the results of calculations.

The study explores factors that affect the performance of responsibility accounting at public universities in Vietnam. The study conducted a survey of 130, out of 154 public universities in Vietnam and uses regression analysis methods. The results identify eight groups of factors affecting the performance of responsibility accounting at these establishments of higher education: Division of the organization into responsibility centers, Estimation and Reality, Cost and income allocation, University autonomy, Management decentralization, Estimation, Reward, and Report. Costs and income allocation for responsibility centers, university autonomy, and the division of universities into responsibility centers are shown to significantly affect the performance of public universities in Vietnam. The results show that the performance of responsibility accounting at public universities in Vietnam is influenced by decentralization of management, division of the organization into responsibility centers, reward, cost and income allocation, estimation, evaluation of the results achieved between the estimation compared with reality, release of reports and university autonomy. Among the factors, cost and income allocation, university autonomy, division of the organization into responsibility centers, reward and evaluation of results achieved between estimation and reality have strong impacts. The study findings also indicate that the school council does not affect responsibility accounting at these universities.
