This study examined a long-standing issue with its perverse results in the Korean capital markets, such as any variant financial profiles over time, affecting capital structure for the firms belonging to the chaebols. It may be of interest to identify these components from the perspectives of international investors and domestic policy makers to implement their contingent strategies on the target leverage, since the U.S. financial turmoils in the late 2000s. Regarding the evidence from the three hypothesis tests on the firms in the chaebols, this research found that the control variabels measuring profitability, business risk, and non-debt tax shields, showed their statistically significant relationships with the different types of a debt ratio. While FCFF(free cash flow to the firm) showed its significant influence to discriminate between the firms in the chaebols and their counterparts, not belonging to the chaebols, BDRELY as the ratio of liabilities to total assets, comprising the enhanced 'Dupont' system, only showed its statistically significant effect on leverage in the context of the parametric and nonparametric tests. In line with the results obtained from the present research, one may expect that a firm in the Korean chaebol, may control or restructure its present level of capital structure to revert to its target optimal capital structure towards maximizing the shareholders' wealth.

The purpose of this study is to analyze the impact of merchants' perceptions of service quality, youth mall creation, and traditional market revitalization on management performance to derive factors that can improve the self-sustainability of the traditional market. In particular, it was intended to predict the practical effect of the youth mall creation project by including merchants' perceptions of the rapidly emerging youth mall to revitalize the traditional market. In this study, 430 small business owners from five private traditional markets in Iksan were surveyed, the research model was verified by analyzing the technical statistics, reliability, and validity of the data collected using the SPSS 21.0 program, and the hypothesis was verified through correlation and regression analysis. Although youth malls are actively promoted at the government level to revitalize traditional markets and improve management performance, this study confirmed that the creation of youth malls in traditional markets does not directly affect traditional market revitalization and management performance, confirming that policies to create youth malls that can actually help revitalize traditional markets and improve management performance in the future need to be promoted.

In most of studies on market efficiency, the stability of risk measures and the normality of residuals unexplained by the pricing model are presumed. This paper re-examines stock splits, taking the possible violation of two assumptions into accounts. The results does not change the previous studies. But, the size of excess returns during the 2-week period before announcements decreases by 43%. The results also support that betas change around announcements and the serial autocorrelation of residuals is caused by events. Based on the results, the existing excess returns are most likely explained as a compensation to old shareholders for unwanted risk increases in their portfolio, or by uses of incorrect betas in testing models. In addition, the model suggested in the paper provides a measure for the speed of adjustment of the market to the new information arrival and the intensity of information contents.

The purpose of this study is to test empirically the effects of Entry Barriers for the stock prices of Venture Business using the Ohlson Model which is modifying and extending in terms of growth and the potential growth energy. Because the traditional Ohlson model(1995) on which the firm's value is determined only based on abnormal earnings and book value have numerous limitations when we evaluate the value of venture Businesses with high technology and new emerging market. In order to overcome these limitations, We can introduce items of net sales growth ratios and industrial property-to-net asset ratios into as proxy variables of the growth and potential growth energy. In the process of analyzing these research tests, we have set three kinds of hypotheses and tested then empirically compared with KOSDAQ ordinary listing business and KOSDAQ venture businesses between long-term analysis and short-term analysis. According to the degree of concentration reflecting HHI index, our empirical research were performed in depth. Therefore, the results of this study show us that all three kinds of Hypotheses are accepted.

The social commerce is an innovative and emerging transaction. It is the result of combination with transaction and social media technology. This study analyzes Korean college students' social commerce behavior through extending technology acceptance model(TAM) with social influence(SI). We confirmed all proposed hypotheses are significant and supported by the given data through PLS path modeling method with SmartPLS. It indicates that SI is an important factor influencing intention to use, so SI should be consider for theorists to enhance explanation and prediction of TAM and for practitioners to earn higher performances as well. Finally, based on the findings, suggestions for future studies are discussed.

지난 두 회에 걸쳐 흔히 사람들이 이야기하는 파라메트릭 디자인의 전형에 가까우며 현재의 건축 및 시공 기술로 충분히 구현이 가능한 두 예를 살펴보았습니다. 조금 지루하다고 여기셨을 분들을 위해 앞으로 몇 회간은 시뮬레이션(simulation)에 대해 이야기를 해 볼까 합니다. 시뮬레이션은 단어가 의미하는 것처럼 실제의 현상을 모방하는 과정을 의미하며 이미 많은 분야에서 다양한 목적을 위해 사용되고 있습니다. 쉽게 머릿속에 떠오르는 시뮬레이션은 아마도 영화나 컴퓨터 게임에서 자연현상이나 물리적 법칙에 의한 사물의 거동 등을 본뜨고자 하는 목적의 특수효과를 위한 시뮬레이션, 과학자들이 자연의 현상의 이해 및 예측, 혹은 가설의 검증 등을 위해 사용하는 시뮬레이션, 엔지니어들이 물체의 물리적 화학적 거동을 시험해 보기 위해 사용하는 시뮬레이션 등이 아닐까 생각합니다. 시뮬레이션은 기본적으로 어떠한 현상에 대한 이해를 바탕으로 그러한 현상을 만들어 내는 법칙을 찾아내어 이를 디지털 모델화 하여야 합니다. 몇 회 전에 말씀드렸던 것처럼, 실험에 실험을 거듭하여 가장 영향력이 큰 변수를 찾아내고 미처 이해하지 못한 변수들을 보강하기 위해 도입하는 상수 등으로 이러한 과학적인 법칙을 도출하게 됩니다. 싸고 막강한 성능의 컴퓨터 및 데이터 저장방법 등을 등에 업은 빅 데이터(Big Data)를 통한 방법론이 이미 통계 및 확률의 분야에서 전통적인 알고리듬에 바탕을 둔 시뮬레이션에 우위를 점하고 있는 상황이긴 하지만, 개인적인 생각으로는 항상 다른 분야에 비해 기술적으로 한발 뒤쳐질 수밖에 없는 건축의 보수적인 속성 및 좀 더 많은 것에 대해 컨트롤을 하고 싶어 하는 많은 건축인들의 애착 등을 고려해 보았을 때 건축에서의 시뮬레이션이라는 영역은 아직도 알아야할 가치가 많다고 생각됩니다.

한국어 문법 연구에서 뿐만 아니라, 현대 언어학에서는 일반적으로 대명사들은 재귀적 대명사와 비재귀적 대명사라는 두 개의 구분된 통사 범주로 분류된다는 대명사의 이분법적 통사 분류 가설이 지배적이다. 그러나 최근 [Hertz 92ab]가 제시한 조응성의 등급(anaphoric scale)이라는 개념에 의거한 본 연구에서는 한국어 대명사들을 두 개의 구분된 통사 범주로 이분하지 않으며 오직 서로 다른 조응도(anaphoric degree)에 의해서만 구분하는 스칼라식 관점을 제안하였다. 한국어 대명사들의 조응도를 기술하기 위해 본 연구에서는 몇 가지 통사 의미적 준거 항목들을 제시하였다. 본 연구의 접근 방법은 그간 많은 연구들에 의해 밝혀진 바와 같은 대명사들의 다양하고도 이질적인 통사 의미 특성들을 자연스럽게 설명하여 줄 수 있다는 장점이 있다. 반면, 이와 같은 대명사들의 통사 의미적 다양성은 전통적인 이분법적 분류의 관점에서는 풀기 어려운 숙제로 남게 된다.

This study investigates human-robot interactions in a museum environment. Unlike robots in movies, robots in real life do not have 'personality,' but instead have a specific purpose and function. This research is primarily about the assignment of specific and appropriate personalities to robots in different contexts. Methods by which a definite personality can be imparted on a robot are discussed in this research. Previous research has addressed attempts to assign a robot personality based on the task context. However, the discussion of robot personality is incomplete. Therefore, we assumed that a robot's character was dependent on the characteristics of its location of use. We planned a $2{\times}2$ comparison of various robot personalities, i.e., introverted or extroverted paired with either a traditional museum or a process-oriented experiential experience. Based on Schmitt's (1999) strategic experiential modules, experiential factors were derived for each set of conditions. To achieve the objectives of the research, theoretical and empirical research were conducted simultaneously. The software JMP 9 was used to verify the research model and hypotheses.

전통적인 통화론자(通貨論者)의 화폐수량설(貨幣數量說)에 의하면 통화량(通貨量)만이 인플레에 영향을 주는 요인으로 파악되고 있다. 본고(本稿)는 인플레가 통화(通貨)의 공급경로(供給經路), 즉 중앙은행(中央銀行)의 발권대상자산(發卷對象資産)의 구성상(構成上)의 차이에 의해서도 영향(影響)을 받는다는 가설에 대한 역사적(歷史的) 이론적(理論的) 전개과정(展開過程)을 살펴보고, 이를 실증적(實證的)으로 검토하였다. 한국(韓國)을 포함한 41개국의 "패널"자료를 이용한 실증분석결과(實證分析結果)에 의하면 인플레가 총통화증가율(總通貨增加率)뿐만 아니라 중앙은행의 발권대상자산(發卷對象資産)의 구성(構成)에 의해서도 영향을 받는 것으로 확인되었다. 즉 국공임(國公賃) 등 정부부문(政府部門)을 대상으로 공급되는 본원통화(本源通貨)는 진성(眞性)어음재할인(再割引) 등 민간부문(民間部門)에 대한 본원통화공급에 비해 인플레에 미치는 영향이 큰 것으로 나타났다. 정부부문에 대한 통화공급은 미래의 재정정책(財政政策)에 대한 불확실성에 따른 정부의 채무상환능력(債務償還能力) 저하의 가능성이 상존하기 때문에 환수가 확실한 민간부문의 단기우량증권(短期優良證卷)을 대상으로 공급되는 통화와는 달리 인플레기대심리(期待心理)를 유발시킨다. 위의 실종분석결과는 향후 물가안정(物價安定)을 위해서 한국은행(韓國銀行)의 대예금은행(對預金銀行) 대출금이 현행의 재정자금적(財政資金的) 성격의 자금위주에서 진성(眞性)어음재할인(再割引) 등 순수민간부문에 대한 신용중심으로 재구성(再構成)되어야 함을 시사한다.

Objectives of this study were: First, the purpose of this study is to develope the factors affecting private brand based on past researches and to review effects of the consumer perception factors affecting private brand preference. Second, to set up research model specifying relationships among price perception, information search and experience, Quality perception and private brand preference. Third, to test hypotheses derived from the research model of this study and to attempts to explain how to have the effect the private brand preference. Marketing implications of this study were: As a result LISREL analysis, price perception, informations search and experience, quality perception increase and enhance private brand preference. Limitations of this study were: Data collection methods used in this study were questionable for the lack of general analysis in the difference of preference between characteristics of purchaser and characteristics of non-purchaser exactly because our sample was only limited to Changwon, Masan and Jinhae. So future study has to include samples in other regions.
