The purpose of this study is to examine which factors are important in determining the amount of the apartment supply in Changwon City. Additionally, this study is to examine the changes in the determination of the amount of apartment supply in Changwon by dividing it into before and after 2016 as the city showed a large difference in apartment supply that caused structural changes during this time period. This study shows that the increase in the number of housing construction permits in Changwon before 2016 had a negative impact on the housing market as well as causing a decrease in the supply of apartments in Changwon after 2016. As a result of the shortsighted predictions on the housing market of Changwon from before 2016, it still affects the current housing market as of June 2020. The implication of this study is that through the housing market system of Changwon City, they can take the role as a control tower in Changwon City and propose principles and standards for supply control in order to better predict the demand of the housing market.

Market-oriented networks support various tasks in the market domain. We analyze trends in structural changes of such networks to adapt to preferences in general market movements. This analysis is different from conventional ones that focus on specific technologies. Instead, we focus on the paradigm shift of network technology from connectivity functionalities to platforms supporting business domains for direct modeling. Moreover, we analyze current development efforts of technologies based on popular and realistic solutions such as FIWARE, 5GinFIRE, IBN, IDN, and HNSP. Remarkably, we detail HNSP as an open research and development platform to experiment with business models and enable co-building with developers. We observe a clear paradigm shift of communications technology from a closed to an open job-shop style.

The study analyzed the current status of fisheries port market and presented the direction of developments. The fisheries port market has become increasingly widespread due to the aging of the facilities and the scale of the fish product trade, and the number of distribution workers has also increased. The problems of fisheries port market are as follows. First, the transaction structure was changed as the proportion of aquaculture products increased. Second, the trading structure has changed, but it has failed to keep pace with the changes in the production structure. Third, the volume and amount of fish traded in aquaculture products and fish stocks increased. As a result, the growth rate of the fisheries port market is decreasing and profitability is deteriorating. The development direction of the fisheries port market is as follows. First, it is necessary to standardize the fisheries port market facilities, according to the type of fish products. Second, it needs to diversify its trade targets such as processed fish products and imported fish products. Third, it is necessary to diversify the business of the fisheries port market in order to increase profitability.

로보어드바이저 서비스 제공업체가 금융시장에서 거래되는 ETF를 주력 투자대상으로 집중하고 있다. 이처럼 ETF가 활성화되고 있지만 ETF 위험관리에 관한 연구들은 이뤄지지 않고 있는 상태이다. 본 연구는 변동성의 구조적 변화를 반영한 ETF 손실추정과 ETF 위험관리모형을 평가하였다. 결합 검증통계량 분석결과, GARCH와 마르코프 국면전환 GARCH모형이 시장위험을 적절하게 나타내 주었다. 특히 마르코프 국면전환 GARCH모형이 GARCH모형에 비해 낮은 위반율을 보일뿐 아니라 초과발생들이 독립적이기 때문에 마르코프 국면전환 GARCH모형이 GARCH모형에 비해 좀 더 ETF VaR에 권고될 수 있다.

본 연구는 지속적으로 구조적 변화를 겪으며 증가하고 있는 외국인의 인구와 주택 소비의 변화가 본국과 이주국의 주택 시장 양쪽 모두에 영향을 미친다는 사실을 밝히는 것에 목적을 둔다. 서울의 조선족 주택 시장의 형성 원인과 변화는 임대료 시장에 있어서 내국인 주택 시장과는 다른 '임대료의 고정 효과'로 인하여 외국인의 유입이 지속적으로 발생하는 것으로 나타났다. 특히 순환 이주 의향이 강한 조선족 집단에 의해 분화된 주택 시장의 밀집은 더욱 심화된 형태로 변화하고 있다. 한편 한국에서 이주 경험이 있는 조선족들이 주요 주택 소비자로 부상하면서, 연길시의 부동산 붐을 일으켰다. 조선족의 주택 투자는 연변 대학을 기준으로 '서부'에 집중되어 있는데, 연길시의 주택 공급에 영향을 미치는 도시 기본 계획과 밀접한 연관 관계를 가지고 있다. 이와 같은 이주자의 초국가적 주택 소비로 인하여, 본국과 이주국의 주택 시장을 연결함으로써 두 주택 시장에서 발생하는 여과과정을 동시에 일으켜, '초국가적 주택 여과 과정(Transnational housing filtering process)'이 발생하게 되는 것으로 나타났다.

This paper investigates the presence of momentum profits in the Saudi stock market. The study applied a quantitative method by utilizing monthly closing prices of 194 listed firms on Tadawal (Saudi Stock Market). The data from January 2010 to February 2019 is taken from the Tadawal market database for analysis. The sample is further divided into two equal sub-samples based on the structural changes that occurred in the Saudi stock market. Moreover, the high- and low-value traded portfolios are also constructed to examine the presence of momentum profits. Sixteen investment strategies are formed for each sample. The results show a very strong presence of momentum profits in the Saudi stock market for the full sample as well as for the sub-samples. The momentum profits are observed for a longer investment horizon. The results confirm that the short or medium-term formation of portfolios produces negative momentum returns for high-value traded stocks. The low-value traded stocks portfolios give similar results to the full sample results in terms of momentum profits. The results suggest that an investor should keep an eye on the past performance of desired stocks for at least three-nine months in which they are willing to invest.

The customer has come to replace the product as a central figure in business competition. The domestic life insurance market has also experienced the rapid structural changes in IT time. The competition in the insurance industry to maintain the existing membership and to attract the new members gets stronger under such a new business circumstance. Accordingly, it is necessary for an individual insurance company to develop a systematic marketing plan, based on the customer information, to be competitive in the market. Unlike other studies in which customer characteristics are neglected, this study attempts to utilize the customer information by applying the data mining technique, and then suggests an efficient marketing strategy that could prevail in the competitive business environment.

본 연구는 룩셈부르크소득연구의 가구소득자료를 이용하여 1980년대 이래 서구 복지국가에서 빈곤의 실태는 어떻게 변화하고 있는가를 분석하고, 빈곤의 변화추세를 인구집단별 및 소득원별로 분해함으로써 경제사회구조 및 공적소득이전제도의 변화가 빈곤의 추세와 어떠한 관련을 맺고 있는지를 탐색하였다. 연구결과는 먼저 대부분의 서구 복지국가에서 빈곤이 심화되는 추세에 있음을 보여 준다. 이처럼 빈곤이 심화되는 추세에 있는 것은 노령층이나 편부모가구 등 전통적으로 빈곤의 위험이 높은 인구집단이 증가하고 있는 때문만은 아니다. 노령층의 경우 연금제도 등 공적소득이전의 영향으로 인해 생산연령층에 비해 빈곤상태가 낮은 수준을 보이고 있으며 시장소득의 빈곤도 점차적으로 감소하는 추세에 있다. 편부모가구는 전반적으로 생산연령층 일반가구에 비해 빈곤의 정도가 심한 편이나 빈곤의 변화추세는 노동시장정책 및 공적소득이전제도의 차이에 따라 국가별로 크게 다르게 나타난다. 서구 복지국가에서 빈곤이 심화되는 것은 무엇보다 생산연령층 인구의 빈곤, 특히 시장소득 빈곤이 심화되고 있는데서 그 원인을 찾을 수 있다. 경제의 세계화와 노동시장 유연화에 따른 실업 및 비정규직의 증가, 저임금 노동자의 증가 등 최근의 경제환경 변화가 생산연령층 인구의 빈곤을 증가시키는 요인으로 작용할 가능성이 높은데, 이에 대한 구체적이고 깊이 있는 분석과 함께 이 계층에 대한 빈곤정책이 확대될 필요가 있다.

This study aims to examine an effective path that links the use of export promotion programs(EPPs) to the export performance of SMEs. In particular, the study focuses on what role the export innovativeness of SMEs plays between EPPs and export performance. In order to verify the conceptual model, the structural equation modeling is applied, using the data collected from a sample of 152 Korean SME exporters. The study highlights the notion that the relationship between the use of EPPs and export performance is not direct and that higher performance can be achieved through export innovativeness, the ability to reconstruct internal resources and to respond quickly to changes in the export market. The results of the empirical analysis show that EPPs partially mediate the relationship between export market-orientation and export innovativeness, and that such mediated export innovativeness continues to fully mediate the relationship between EPPs and export performance. That is, if SMEs make good use of EPPs that meet their needs, they can be encouraged to re-bundle or strengthen their existing resources and capabilities, which in turn lead to higher export performance. The study thus helps extend understanding of EPPs and export performance literature.
