이 연구는 투자이론에서 활용되고 있는 토빈의 Q 개념을 적용하여 투자이익을 측정하고 이를 통해 서울 주택시장을 이해하고자 한다. 구체적으로 서울시 아파트와 연립·다세대주택을 대상으로 2010년부터 2018년까지 투자이익을 추정하고 공간계량모형을 이용하여 투자이익에 영향을 주는 요인들을 살펴보았다. 투자이익은 실거래가격에서 대체비용(토지비용+건축비용)을 빼는 방식과 실거래가격 대비 대체비용의 비율로 각각 추정하였다. 분석결과를 보면, 투자이익은 2018년으로 갈수록 더 커졌고 강남·서초구 및 한강 주변에서 투자이익이 높게 나타났으나 투자이익의 시공간적 변화양상은 아파트의 경우 뚜렷한 반면에 연립·다세대주택은 산발적·국지적으로 나타났다. 공간계량모형 분석결과는 주택유형과 상관없이 고밀·신축개발이 많은 지역에서 투자이익이 높았다. 이 연구의 접근방법과 결과는 향후 주택 공급 정책, 투자이익 환수, 지역 경쟁력 측정, 가격 거품 측정 등에 대한 논의를 위한 기초 자료가 될 것이다.

The paper aims to examine the factors affecting brand and student decision in buying fresh milk. Combining qualitative and quantitative research methods, this study used self-completed questionnaires to investigate 520 students in Ho Chi Minh City. The results of the study show that that there are five key determinants affecting the dairy brand and student decision in buying fresh milk, including: (1) product quality, (2) fair price, (3) product promotion and customer services, (4) product convenience, and (5) reference group's attitude to the brand. In addition, it is also found that product brand has a direct and positive impact on the student decision. The finding in this study is quite different from other existing literatures in terms of the importance level of the determinants of the student decision in buying fresh milk; specifically, in deciding to buy their fresh milk, students are often interested in the promotion and customer service, the product convenience, and the reference group for the purchase, more than in the quality and price of the product. From these findings, some managerial implications are proposed for policy-makers and relevant enterprises to have appropriate policies and strategies for their business development.

최근 부유층 주거지에 특정 목적에 의한 중 저소득층이 진입, 준거집단에 합류하며 과시효과를 누리고 싶어 한다. 이 현상으로 주거용부동산에 대해 유한계급층이 아닌 일반 소비자들의 과시효과에 대한 욕구를 유추할 수 있다. 과시소비를 함으로써 고가의 상품을 구매할 수 있는 준거집단에 속한다는 우월함과 고가를 지불할 수 있는 능력을 통해 부를 전시하는 효과를 얻는다고 볼 때 자신의 사회경제적 능력을 보이기 위한 과시적 소비성향은 주거용부동산에도 영향을 미치리라고 예상된다. 본 연구에서는 주거부동산의 거주유형에 따른 베블런효과를 확인하고자 하였다. 이를 위해 다양한 심리적 특성, 주거특성, 인구사회학적 특성이 베블런효과에 미치는 영향을 PLS 경로모형을 이용하여 분석하였다. 분석결과 차가거주자가 자가거주자에 비해 과시소비성향이 높은 것으로 나타났으며, 체면민감성은 자아존중감과 주거유형에 정(+)의 영향을 미치며 이는 과시소비성향으로 이어진다. 또한 거주면적이 크고 소득수준이 높을수록 과시소비성향이 큰 것으로 확인되었다.

이 연구는 다차원적 관점에 따라 개발된 관여척도를 적용하여 제품관여가 소비자 구매과정에 미치는 영향을 분석하였다. 실증자료 분석결과, 제품별 분석에서 보다 소비자별 분석에서 '구매전 정보탐색'을 비롯한 구매과정의 행동성향이 관여수준에 더 강하게 의존되는 것으로 나타났다. 이는 관여수준이 소비자선택행동의 변화를 설명해주는 구조물이며, 제품관여는 소비자가 제품에 관련되는 정도를 반영하는 변수로 인식되어야 함을 시사한다. 동시에, 관여가 소비자행동에 미치는 영향의 이해와 예언에는 관여수준과 함께 관여의 관저에 대한 이해가 필요하다는 시사를 얻었다.

This study proviedes GARCH model(Bollerslev, 1986) to analyze the structural characteristics of price volatility in domestic aquacultural fish market of Korea. As a case study, flatfish and rock-fish are analyzed as major species with relatively high portion in an aspect of production volume among fish captured in Korea. For analyzing, this study uses daily market data (dating from Jan 1 2000 to June 30, 2008) published by the Noryangjin Fisheries Wholesale Market which is located in Seoul of Korea. This study performs normality test on trading volume and price volatility of flatfish and rock-fish as an advanced empirical approach. The normality test adopted is Jarque-Bera test statistic. As a result, first, a null hypothesis that "an empirical distribution follows normal distribution" was rejected in both fishes. The distribution of daily market data of them were not only biased toward positive(+) direction in terms of kurtosis and skewness, but also characterized by leptokurtic distribution with long right tail. Secondly, serial correlations were found in data on market trading volume and price volatility of two species during very long period. Thirdly, the results of unit root test and ARCH-LM test showed that all data of time series were very stationary and demonstrated effects of ARCH. These statistical characteristics can be explained as a reasonable ground for supporting the fitness of GARCH model in order to estimate conditional variances that reveal price volatility in empirical analysis. From empirical data analysis above, this study drew the following conclusions. First of all, from an empirical analysis on potential effects of seasonality and the day of week on price volatility of aquacultural fish, Monday effects were found in both species and Thursday and Friday effects were also found in flatfish. This indicates that Monday is effective in expanding price volatility of aquacultural fish market and also Monday has higher effects upon the price volatility of fish than other days of week have since it has more new information for weekend. Secondly, the empirical analysis led to a common conclusion that there was very high price volatility of flatfish and rock-fish. This points out that the persistency parameter($\lambda$), an index of possibility for current volatility to sustain similarly in the future, was higher than 0.8-equivalently nearly to 1-in both flatfish and rock-fish, which presents volatility clustering. Also, this study estimated and compared and model that hypothesized normal distributions in order to determine fitness of respective models. As a result, the fitness of GARCH(1, 1)-t model was better than model where the distribution of error term was hypothesized through-distribution due to characteristics of fat-tailed distribution, was also better than model, as described in the results of basic statistic analysis. In conclusion, this study has an important mean in that it was introduced firstly in Korea to investigate in price volatility of Korean aquacultural fishery products, although there was partially a limited of official statistic data. Therefore, it is expected that the results of this study will be useful as a reference material for making and assessing governmental policies. Also, it is looked forward that the results will be helpful to build a fishery business plan as and aspect of producer, and also to take timely measures to potential price fluctuations of fishery products in market. Hence, it is advisable that further studies related to such price volatility in fishery market will extend and evolve into a wider variety of articles and issues in near future.

This paper presents a new approach for evaluating the transmission marginal loss factors (MLFs) considering the reactive power. Generally, MLFs are represented as the sensitivity of transmission losses, which is computed from the change of the generation at reference bus by the change of the load at the arbitrary bus-i. The conventional evaluation method for MLFs uses the only H matrix, which is a part of jacobian matrix. Therefore, the MLFs computed by the existing method, don't consider the effect of the reactive power, although the transmission losses are a function of the reactive power as well as the active power. To compensate the limits of the existing method for evaluating MLFs, the power factor at the bus-i is introduced for reflecting the effect of the reactive power in the evaluation method of the MLFs. Also, MLFs calculated by the developed method are applied to energy spot markets to reflect the impacts of reactive power. This method is tested with the sample system with 5-bus, and analyzed how much MLFs have an effect on the bidding/offer price, market clearing price(MCP), and settlement in the competitive energy spot market. This paper compared the results of MLFs calculated by the existing and proposed method for the IEEE 14-bus system, and the KEPCO system.

This study was to evaluate the taste of the wine assessment gap analysis to compare the taste of the wine intended for college student wine consumers and wine experts. Research analysis was carried out frequency analysis to the strength of the wine taste a difference in the intensity of the consistency review and wine for the wine flavor between the two groups. According to result, red wine, bitter and salty taste was perceived higher. For white wines are perceived sweetness of wine was sour and higher consumer groups. Body was found that wine experts perceive higher. The Second difficulty is when college student wine consumers selected wine got another show to the lack of information, lack of expertise, price, taste, the combination of food. Another wine on difficult points during the wine expert wine recommendations wine selection, price, prejudices then guest it showed a preference and communication, considering that the customer's budget, customer preferences, taste and aroma, the combination of the food and the customer response was configured. Although the criteria have different tastes for wine through college student wine consumers if future studies presented by symbolic reference to the wine tasting, can be self-objectification of subjective criteria subjective wine experts are wine consumers to take advantage of these data.

Korean agricultural and rural economics has been gotten more difficult through the introduction of economics system under the control of IMF before problems from open market system under WTO get to be settled. Export should be promoted to get the advantage of open market system and to get over today's economic crisis from shortage of foreign currency. Fortunately, Korea adjoins Japan that is largest importing country of agricultural products in a world, therefore Korean Agricultural products has advantage in export to Japan through open market system. Puyo tomato, specialized agricultural products in Chungman province, has been exported 42.2M/T to Japan from 1994 year to 1996 year. But such exported amount was so small that is less than a 1% of total tomato product in Puyo area. Reasons why export volume to Japan was so small were non standard commodities, non performance of export contract, unfavorable price condition, etc.. But it was major reason that missed optimal exporting period. Therefore this study is aimed at finding optimal period exporting Puyo mini tomato to Japan. According to result of analysis based on monthly price and carried quality data of major tomato market between Korea and Japan, it has more comparative advantage that we export tomato during Period of Dec-Feb. rather than March-May which is currently major exporting period.

Purpose: This study is to explore how Netflix Customers' Engagement was influenced by Instagram Content, Perceived Price, Exclusivity, and Motivation in the context of Media Streaming and the role of Willingness to Subscribe as the mediating variable. This study underlines millennial's willingness to engage and the form of engagement. Research design, data, and methodology: The data for this research were collected from 100 Netflix's Millennials subscribers who follow @netflixid Instagram. All the results were analyzed and verified using SEM-PLS. Results: Research findings indicated that Willingness to Subscribe, Exclusivity, Motivation, and Instagram Content positively influenced Customer Engagement among Netflix millennials' subscribers. In contrast, Perceived Price had a negative effect on Customer Engagement. Conclusions: As a consequence, the exclusivity that Netflix offers to its audience by a recommendation algorithm has been proven to increase the engagement. This study also disclosed that the most definite form of positive engagement shown by Netflix millennials' subscribers is a behavioral aspect, where they positively recommend Netflix (word of mouth). The study findings can be a reference for the media streaming industry in their efforts to strengthen the engagement with their customers, especially the millennials, and provide knowledge about consumer behavior in digital technology.
