Purpose - This study aims to investigate the current state of distribution terminology usage by retailers and consumers nationwide, and to suggest a practical improvement plan for its standardization. The Korean distribution industry is closely related to consumers' daily lives. However, in reality, there exists a gap among producers, distributors, and consumers in terms of the definition, understanding, and perception of the terminology. Therefore, standardizing this terminology is essential for more smooth communication. This paper suggests the necessity of committing overall research and survey activities to the actual conditions of using Korean distribution terminology by organizations and their respective management situations, and further, the necessity of probing the problem and its measures in line with the objective and mission of the "Fundamental Law of the Korean Language." Research design, data, and methodology - This study's scope is limited to wholesale and retail including some information systems. First, the study covers most written material including lexicons and glossary of distribution terminology, university textbooks and teaching material for national certificate of qualification, and related laws and ordinances. Second, the survey covers retailers' management situations by store format. The retailers used as the sample for the survey include department stores, discount stores, SSM, and convenience stores. Altogether, 20 specialists were interviewed in their respective sectors or retail formats. Finally, the project team surveyed a sample of 1,300 consumers nationwide on 50 distribution terms mainly used by consumers, including those about awareness, understanding, usage, and attitude. Results - In total, 1,249 terms are drawn through literature research including distribution terminology used in the related literature, glossary and lexicons, distribution terminology in textbooks, and legal terminology. A classified table comprises four large categories including general distribution, distribution marketing, distribution information, and merchandise. The results of the three-step research including literature survey, field survey of retailers, and consumer survey were advised to be screened by academia (retail associations, faculty etc.), retailers (major retail management by store format), retail specialists and consultants, consumers, and Korean linguists. In total, 1,300 questionnaires for 50 terms of the distribution terminology closely associated with consumers were distributed to subjects nationwide. Conclusions - The desired and expected results from this study are summarized from three perspectives as follows: First, from retailers' perspective, a new concept, or coinage of new terms of the distribution industry stems from advanced countries such as America and Europe. However, the original meaning and definition are diluted and distorted with changes in the language users' situations and context. This study provides basic guidelines for standardization of distribution terms used among various retail formats in most daily life situations that consumers encounter. Second, from the nation's perspective, this study suggests optimal choices of distribution terminology in the context of laws and ordinances regarding concerned Ministries. Last, from the consumers' perspective, this paper enables consumers to understand and use distribution terms properly in their daily life.

Purpose: North Korea is a very close country geographically and culturally, but the nation has been one of the most secretive countries in the world. However, in recent years, North Korean society has been known to rapidly change its economic environment as well as its diplomatic and political environment. Since the gaining power of Jong-un, Kim in 2012, the North Korean government has implemented a new set of economic policies. North Korea has embraced limited market systems and mechanisms that have become a part of the formal planned economy. This study is concerned with the recent changes in the market and marketing activities of the communist country. It also seeks to gain an understanding of the changing market behavior of North Korean consumers. The purpose of this study is to enhance understanding of the market environments of North Korea and to provide appropriate implications for practitioners and researchers. Research design, data and methodology: Academic access to information that can understand North Korea's reality is minimal. Therefore, this study was conducted based on a qualitative analysis of secondary data. The existing literature on North Korea, related news and reports were the basis of the analysis. Analysis of secondary data related to North Korea was the main methodology of the study. Results: The official ideology of North Korea rejected most aspects of marketing, and yet there were marketing activities in North Korea. This article focuses on the development of market and marketing activities in North Korea during the recent years. This study indirectly confirmed that the market function is being activated in North Korea, and the basic functions of marketing such as advertisement, price, and distribution are being formed. In this process, the activation of the 'Jangmadang(market)' played a significant role. Conclusions: Research shows that North Korea is rapidly developing its own market function. In addition, marketing activities such as advertising and pricing strategies seem to be unprecedentedly active. However, due to changes in the political environment, the future development of North Korea's marketing is still in flux. Efforts to improve mutual understanding through continuous research are required.

디지털 환경의 전자 상거래는 종래의 물리적 환경(현실환경)에서의 상거래와는 마케팅, 유통구조 둥 여러 측면에서 차이를 나타내고 있으나 특히 소비자의 상품 구매형태에 큰 차이가 있다. 기존의 구매패턴은 제품을 보고 만지고 시험하면서 체험적으로 느껴, 제품의 가치를 판단하여 구매하였는데 이에 반해 디지털 환경하의 전자상거래는 컴퓨터 모니터화면에서 얻은 정보에 의해 제품의 가치를 판단하게 되어 구매 판단의사를 결정하게 된다. 현재 출시되고 있는 제품의 대다수는 상거래 공간이 디지털 환경이 아닌 현실환경으로 설정하여 일련의 디자인 프로세스에 따라 소비자에게 어필할 수 있게끔 디자인하였다. 그러나 하루가 다르게 디지털 환경인 사이버공간에서 전자 상거래가 이루어지는 이 현실을 감안하여 본다면 디지털 환경에 적극적으로 어필할 수 있는 디자인물을 내놓아야 할 것이다. 서로 다른 두 환경에서 또 같은 제품디자인의 이미지를 피험자들은 어떻게 인식하고 있는지를 파악하기 위하여 요인분석을 실시하였다. 그 결과 제1요인에서 서로 상이한 이미지를 가지고 있음을 알 수 있었다. 상이한 이미지를 가지고 있는 배경에는 각각의 환경에 따를 이미지에 영향을 미치는 조형적 요소의 전달이 상이하기 때문인 것을 알았다.

최근 VR(Virtual Reality)에 대한 사람들의 관심이 높아짐에 따라 주변기기 또한 많은 발전이 이루어졌다. VR 환경에서 그 환경내의 사물과 인터랙션 할 수 있는 여러 인터페이스 장치와 룸 단위의 스캐닝을 통한 VR 환경 구성까지 많은 연구가 이루어지고 있다. 현재 VR의 동향을 보았을 때 가정에서의 VR 활용법은 여러 햅틱 인터페이스를 이용하여 VR 환경 내에 구성된 사물들과 인터랙션 하는 것이 많으며 룸 스캐닝을 이용한 방법으로 공간상의 제약을 어느 정도 벗어나기도 하며, 트레킹 장비를 이용하여 실제 사물들과의 인터랙션을 하기도 한다. 3D 프린터의 발전으로 상업용 3D 프린터와 가정용 3D 프린터의 보급이 활성화 되었으며, 3D 프린팅 업체 또는 가정에서 쉽게 3D 프린터를 통해 자신이 원하는 모형을 만들 수 있게 되었다. 위 두 가지를 고려하였을 때 VR 환경에서 사람들이 쉽게 만들 수 있는 모형을 가지고 직접 인터랙션을 할 때 사람들이 느끼는 모형의 물체감과 VR 환경상에서 구성된 모형의 물체감 사이의 차이점에 대한 연구가 필요하다고 느껴진다. 따라서 이 논문에서는 3D 프린터로 제작한 사물을 VR 공간 내에 구현하고 실제로 구현된 그 사물과의 사용자 테스트를 통해 실제 사물과 인터랙션 할 때와 다른 일반 인터랙션 장비를 사용할 때의 차이에 대한 연구를 하고자 한다.

Background: Parametric statistical procedures are typically conducted under the condition in which a sample distribution is statistically identical with its population. In reality, investigators use inferential statistics to estimate parameters based on the sample drawn because population distributions are unknown. The uncertainty of limited data from the sample such as lack of sample size may be a challenge in most rehabilitation studies. Objects: The purpose of this study is to review the bootstrapping method to overcome shortcomings of limited sample size in rehabilitation studies. Methods: Articles were reviewed. Results: Bootstrapping method is a statistical procedure that permits the iterative re-sampling with replacement from a sample when the population distribution is unknown. This statistical procedure is to enhance the representativeness of the population being studied and to determine estimates of the parameters when sample size are too limited to generalize the study outcome to target population. The bootstrapping method would overcome limitations such as type II error resulting from small sample sizes. An application on a typical data of a study represented how to deal with challenges of estimating a parameter from small sample size and enhance the uncertainty with optimal confidence intervals and levels. Conclusion: Bootstrapping method may be an effective statistical procedure reducing the standard error of population parameters under the condition requiring both acceptable confidence intervals and confidence level (i.e., p=.05).

The Act on Distribution and Price Stabilization of Agricultural and Fisheries Product, which specifies rules and regulations on the trading system of fishery products wholesales markets, has been revised several times, mainly in order to improve the trading system. However, there is still a huge gap between the reality and law when it comes to the trading system of the fishery products wholesale market. This study aims to analyze the problems of the trading system of the fishery products wholesale market and to suggest ways to make improvement. The main problem facing the trading system of the fishery products wholesale market is sales on consignment by intermediate wholesalers, and this paper suggests two alternatives to solve the problem. First, intermediate wholesaler can be converted to market wholesalers, but it also entails other problems. The market wholesaler system has never been successfully adopted in the agricultural and fishery products wholesale market, and it is not clear which system is better between the wholesale market corporation and the market wholesaler system. Second, sales on consignment by intermediate wholesalers can be adopted with a positive view toward it. Negotiation transaction can be carried out for sales on consignment as a transaction method under the current Act on Distribution and Price Stabilization of Agricultural and Fisheries Products. However, since the act cannot provide a solution for listing, it is necessary to introduce Japan's negotiated transaction in advance system as a negotiation transaction method.

In practical design of girder bridges or reinforced concrete slab bridges with T-type piers, it is usually assumed that vertical movements of superstructures are completely restrained at the locations of bearings(shoes) on a cap beam of the pier, The resulting vertical reactions are applied to the bearing for the calculation of bending moments and shear forces in the cap beam. However, in reality, the overhang parts of the cap beam will deform under the dead load of superstructures and the live load so that it may act as an elastic foundation. Due to the settlement of the elastic foundation, the actual distribution of the reactions at the bearings along the cap beam may be different from that obtained under the assumption that the vertical movements are fixed at the bearings. In the present study, investigated is the effects of elastic deformations of the T-type pier on the distribution of reactions at the bearings along the cap beam through 3-dimensional finite element analysis. Herein, for this purpose the whole structural system including the superstructure and piers as well is analyzed. It appears that the conventional practice which neglects the elastic deformations of the cap beam exhibits considerably different distributions of the reactions as compared with those obtained from the present finite element analysis. It is, therefore, recommended that in order to assess the reactions at bearings correctly the whole structural system be analyzed using 3-dimensional finite element analysis.
