  • Speech act is the speaker's intentions indicated through utterances. It is important for understanding natural language dialogues and generating responses. This paper proposes the method of two stage that increases the performance of the korean speech act decision. The first stage is to select features from the part of speech results in sentence and from the context that uses previous speech acts. We use x$^2$ statistics(CHI) for selecting features that have showed high performance in text categorization. The second stage is to determine speech act with selected features and Neural Network. The proposed method shows the possibility of automatic speech act decision using only POS results, makes good performance by using the higher informative features and speed up by decreasing the number of features. We tested the system using our proposed method in Korean dialogue corpus transcribed from recording in real fields, and this corpus consists of 10,285 utterances and 17 speech acts. We trained it with 8,349 utterances and have test it with 1,936 utterances, obtained the correct speech act for 1,709 utterances(88.3%). This result is about 8% higher accuracy than without selecting features.

  • Competence-competence refers to an arbitratorpower to determine whether he or she has jurisdiction to decide a controversy. Although arbitrators power to rule on their own jurisdiction is generally recognized throughout the world, in the United States, neither the courts nor legislative bodies have recognized its significance or the reasoning behind its widespread adoption. Section 3 of the Federal Arbitration Act (FAA) is notorious among arbitration statues for its failure to incorporate competence-competence. When courts rule on an issue of competence-competence, it is referred to as a question of who decides the arbitrability of the case. In the United States, the use of competence-competence as a term of art is still limited to scholarly writings. The answer to the competence-competence inquiry is found in an interpretation of section 3 of the FAA which empowers the courts to decide arbitrability issues. The cases of the Supreme Court and most commentators interpreted sections 2 and 3 of the FAA as conferring issues of arbitrability on the federal courts, including the ability to rule on the validity and scope of the arbitral agreement. Traditionally, United States courts have denied the competence-competence to arbitral tribunal. Recently, however, they have confounded the rules by placing primary importance on the arbitration agreement between the parties. The Supreme Court, in a series of cases, has underscored the necessity of giving full effect to the intentions of the parties as expressed in their agreement to arbitrate. The result of the Supreme Court's emphasis on contractualism in determining the issue of arbitrability is most evident in the Courtdecision in the First Options case. Under First Options, courts are to decide arbitrability issues unless there is a clear and unmistakable contractual assignment of these issues to the tribunal itself. The Court is appraised that it has attempted to compromise between contractual freedom in the arbitration setting and the rule of law that is necessary in a society that depends on the concept of ordered liberty. In the decision in Howsam, the Court clarified the definition of arbitrability by attempting to draw a clear line between questions of arbitrability that are to be decided by courts and those matters that bear on the allocation of decisions between courts and arbitrators but are not questions of arbitrability.

  • There is a need to develop diverse cultivation species with reference to the favorites and farming experiences of allotment garden participants, in addition to the crops being cultivated in the gardens. In this study, therefore, a survey on the status of cultivation and the demand for herb crops for the garden participants was conducted. Current trend of the programmes related to allotment garden for city dwellers, executed by various relevant organizations was analyzed. A questionnaire was accomplished by adult participants experiencing farming in allotments. Likewise, interview with farm proprietors was conducted. The results showed that the number of crop species cultivated in allotments was about ten species. The purchase of seeds and nursery plants was mainly dependent on the farmland proprietors. The selection of the crops was made by both wife and husband. The status of herb utilization indicated that 5.7% of participants were cultivating or had cultivated herb plants. Sixty-two percent of participants were not cultivating herb plants because they did not know how. The purposes of using herbs were for medicine and beauty (22.0%), for spices (22.0%) and for enjoyment (29.0%). Thirty-four percent (34.0%) of participants were interested or would like to use the herbs in the future for medicine and beauty, 39.0% for spices and 31.7% for enjoyment. It is expected that the demand for herbs would increase. Also, 78.3% of participants had the intension or had taken into consideration to cultivate the herb plants, if the farmland proprietors would provide the plants. And, they had interest in planting, management and post harvest utilization and if a reference material would be provided as well. An approach to plant new crops might be possible to those who have more than four years of farming experience and possess relatively high level of cultivation techniques. In conclusion, the favorable crop cultivation strategy corresponding to the participants' abilities; and rental process were essential for the sustainable operation of allotment gardens and expanded number of participants. Moreover, there is a need to pay attention to the city dwellers who have a lot of farming experiences in allotment gardens to maintain agriculture and rural community. This is so, because they are interested in agriculture and rural community and most of them replied that they had intentions to move to rural areas in the future.

  • The purpose of this study is to examine the effects of personal characteristics and social entrepreneurship on social entrepreneurship intention, and to determine whether the moderating effect of gender influences on the relationship between personal characteristics and social entrepreneurship. In order to achieve these research objectives, the personal characteristics affecting social entrepreneurship were identified with moral obligation, self-efficacy, and emotional intelligence. Also, prior studies on social entrepreneurship and social enterprise entrepreneurship intention were reviewed. As a result of the study, we find that moral obligation, self-efficacy, and emotional intelligence all had a positive effect on social entrepreneurship. Second, social entrepreneurship had a positive effect on social enterprise entrepreneurship intentions. Third, analyzing the moderating effect of men and women in the relationship between personal characteristics and social entrepreneurship, it was found that there was a difference in the value of the path coefficient representing the relationship between moral obligation and social entrepreneurship. However, there was no moderating effect in the relationship between self-efficacy, emotional intelligence, and social entrepreneurship by gender. Therefore, this study is expected to serve as a reference for people who want to start a social enterprise in the future to verify their characteristics and use them as a way to improve their social entrepreneurship.

  • Purpose - The purpose of this study is to examine whether the cash policies of retail firms listed on Korean stock markets are consistent with the evidence provided in the study of Almeida et al. (2004). Liquidity management is an important issue for financially constrained firms relative to financially unconstrained firms. Because there are few sources of external funding, the optimal liquidity policies of financially constrained firms should reflect their own earnings or cash inflows to create opportunities for current and future real investments. According to this simple idea, we estimate the sensitivity of cash to cash flows and simply check whether the estimated sensitivity to cash flows of the cash retained by constrained retail firms is greater than that of the cash retained by unconstrained retail firms. Through this work, we aim to explain why the cash policies of the retail firms listed on the Korean stock markets differ from those of listed manufacturing enterprises. Research design, data, and methodology - To explain a firm's cash holdings, we use only three explanatory variables: earnings before interest and taxes (EBIT), Tobin's q, and size. All the variables are defined as the value of the numerator divided by aggregate assets. Thanks to this definition, it is possible to treat all the sample firms as a single large firm. The sample financial data for this study are collected from the retail enterprises listed on the KOSPI and KOSDAQ markets from 1991 to 2013. We can obtain these data from WISEfn, the financial information company. This study's methodology has its origin in Keynes's simple idea of precautionary liquidity demand: When a firm faces financial constraints, cash savings from earnings or cash inflows become important from the corporate finance perspective. Following this simple idea, Almeida et al. (2004) developed their theoretical model and found empirical evidence that the sensitivity of cash to cash flows varies systematically according to different types of financing frictions. To find more empirical evidence for this idea, we examined the cash flow sensitivity of the cash held by Korean retail firms. Results - Through several robustness tests, we empirically showed that financially constrained Korean retail firms display significant positive propensity to save cash from earnings before interest and taxes, while the estimated cash flow sensitivity of the cash held by unconstrained retail firms is not significant. Despite the relatively low earnings of retail firms, their sensitivity is three times greater than that of manufacturing enterprises. This implies that Korean retail firms have greater intentions of facilitating future investments rather than current investments. Conclusions - The characteristics of the cash policies of Korean retail firms differ from those of manufacturing firms. This contrast may be attributable to industry-oriented policy planning, regulations, and institutional differences. However, the industrial policymakers should observe signals of the long-term growth options of retail firms based on their high propensity to save from their cash inflows.

  • The problem of choosing the right product that will best fit a consumer's taste and preferences extends to the field of electronic commerce. However, e-commerce has been able to create a technological proxy for the social filtering process, known as online recommender systems (RSs). RSs aid users in filtering products and decisions on matters relating to personal taste. RSs have the potential to support and improve the quality of the decisions consumers make when searching for and selecting products and services online. However, most previous research on RSs has focused on the accuracy of the algorithms, with little emphasis on user interface and perspectives. This study identified transparency and feedback as possible ways to effectively evaluate RSs from the user's perspective. Thus, this research focused on examining and identifying the roles of transparency and feedback in recommender systems and how they affect users' attitudes toward the system. Results of the study showed that both transparency and feedback positively and significantly affected perceived trust, perceived value of the process, and perceived enjoyment. Furthermore, we found that perceived trust, perceived value of the process, and perceived enjoyment positively and directly affected users' intentions to use/reuse a recommender system.

  • The majority of previous research on start-ups consist of research on leading variables that affect the entrepreneurial intention related to start-ups established by young people, college students or senior citizens, and the influencing relationships regarding start-ups in the sense of their form such as independent start-ups, franchising start-ups, small business start-ups, etc. It is difficult to find research on entrepreneurial intention targeting office workers. This study investigates the question of how office workers' entrepreneurial mindset affects their entrepreneurial intentions, focusing on mediating role of social capital and moderating role of state-action orientation. We use survey data to empirically test the relationships between the variables in question. This study finds the presence of the positive effect of entrepreneurial mindset on social capital that significantly promotes entrepreneurial intention, demonstrating mediating role of social capital. We understand the existence of moderator, action state, showing that entrepreneurial intention is affected by interaction of entrepreneurial mindset and action state, not entrepreneurial mindset alone. We propose some policy implications based on the results of this study, and lists the limitations of the study.

  • Purpose - This study empirically analyzes the effect of improvements in the quality of service management performance of college education on traders' conscious change of business management innovation and diverse sales expertise for a year. The use of traders' conscious changes and sales expertise as variables for the verification of the effects of parameters related to the active trader's traditional education market is a desirable direction. The method of research reflects the quality of education service, management result, traders' conscious changes, and sales expertise to understand the precise essence and definition of teaching quality at merchant colleges through theoretical consideration. Moreover, its impact on traders' conscious changes and sales expertise in empirical analysis acts as an intermediary. Research design, data, methodology - The hypothesis of this study leverages the SPSS statistical program. To gather actual proof, sample survey for theoretical research examined 262 valid papers of the 300 papers written by 10 merchants who graduated from merchant's university. First, using the SERVQUAL model, Parasuraman et al. (1996) indicated that for quality of education service, the configuration of factors is the same as the sympathetic performance, that is, responsiveness and empathy, and traders are aware of these elements. However, our preliminary investigation revealed that traders' university education has been excluded as a component of quality of service in the earlier studies. Moreover, we found that certainty of knowledge, reliability, and sympathy are influenced by challenges and by the changing intentions of merchant consciousness. In addition, our study confirms that improvements in convincing abilities and sales technique have a positive impact. Second, merchants' and traders' expertise are proven to affect business performance. In other words, university education of traders and merchants affects the consciousness of consumers, and changes patterns of sales. Third, the quality of service management education and change in the consciousness has a considerable impact on the trader, thereby maximizing business performance and acting as an intermediary for verification. Fourth, the quality of service management education affects the trader's sales expertise to maximize business performance. Results - To summarize, the quality of college educational services relates to the improvement of business performance and the role of the resulting virtuous cycle. Consequently, we can look for suggestions in the traditional markets, where the Government pays attention to the exterior environmental factors as well as to the changing business environment. However, the most important aspect is the merchant awareness. That is, a merchant should understand the distribution environment. Several competitor and trend analyses should be conducted to meet customers' expectations positively and proactively cope with any challenges related to changes. Further, expertise in sales and marketing skills need to be acquired to improve customer convincing abilities and develop a customer-oriented mindset. Conclusions - According to the changes in consumption trends of business enterprises, new management techniques are required to survive competition by improving traditional markets, which will necessitate more competitive education programs in merchant universities.

  • The purpose of this study is to contribute the improvement of national welfare by presenting of pension welfare business of Korea and Japan. The reason why I take the management of Japan's pension accumulation as the object of comparative study is that the history of pension system of Japan is relatively longer than that of Korea. First of all, National Pension Fund comes into use for public sector, financial sector, and welfare sector, The scale of pension management for welfare sector is 50 small. Therefore, the study for welfare business investment reflecting the intentions of pension entries and pensioners is needs of times. This study defines the concept of welfare investment business and prospects welfare investment business of the future on the basis of Japanese experiences, and then suggests the direction of efficient propulsion of welfare investment business to the reasonable decision-makers. Especially this study redefine the concept of welfare investment business on the basis of pension entry's social benefits which are composed of pension entry's gains and pensioner's gain. Of course, welfare investment business has to be presupposed the stability of pension system and the continuous contribution to national economy. Thus, in order to efficiently perform welfare business, the policy-making for national welfare improvement has to be established after the good of business is set up like the results of this study.
