There have been vast amount studies regarding immunologic dysregulation in schizophrenia. The mechanism of immune pathogenesis in schizophrenia still is unclear, even though various immune dysfunction have been reported. We endeavored to report on two major hypothesis on immunologic dysregulation in schizophrenia, the infection hypothesis and autoimmune hypothesis. We went on to focus on the autoimmune hypothesis, which has received the most attention over the years. We explored the accumulated data and the rational behind the autoimmune hypothesis and the implications of the autoimmune hypothesis for future research in the pathogenesis of schizophrenia.

Previous research has demonstrated that happy moods are known to promote feeling-based processing, whereas sad moods promote reason-based processing. The current research investigates a boundary condition for the effects of a happy mood on feeling-based decision making. This research proposes that the level of control (low vs. high) one exercises in a happy situation can promote a greater reliance on feelings (vs. reasons) in making judgments and decisions. Specifically, we hypothesize that (1) a happy individual in a situation where control level is low (vs. high) will be more likely to choose a cognitively (vs. affectively) superior option (hypothesis 1), and (2) a happy individual in a situation where control level is low (vs. high) will exert reason- (vs. feeling-) based processing (hypothesis 2). Consistent with the hypothesis 1, the results of two experiments show that happy individuals are more likely to choose cognitively versus affectively superior options in a situation where control level is low (vs. high). Moreover, the mediation analysis confirms that happy individuals are more likely to rely on cognitive, reason-based decision making when their control level is low, which supports the hypothesis 2.

이 연구의 목적은 초등학생들이 과학적 가설을 생성하는 동안에 나타나는 동공크기의 변화를 분석하는데 있다. 연구 참여자는 서울소재의 B초등학교 5학년 학생들 중 자발적으로 연구에 참여하기를 희망하는 학생들 20명으로 구성하였다. 과제는 4개의 과학적 가설 생성과제로 이루어졌으며, 안구운동 데이터를 얻기 위해서 SMI사의 안구운동 추적기(iView $X^{TM}$ RED)기를 사용하였다. Experiment 3.6와 BeGaze 3.6 프로그램을 사용하여 실험을 계획하고 수행하였으며, 안구운동을 수집하여 분석하였다. 연구결과는 두 가지이다. 첫째, 실험과제에 대해 가설을 생성하는 유형으로 4가지 유형이 나타났다. 둘째, 가설을 생성할 때 동공크기의 특징 있는 변화가 있었으며, 가설을 생성하기 위해 생각하거나 가설을 정교화 하는 과정에서는 큰 변화가 없었다. 이와 같은 연구 결과로 볼 때, 가설을 생성하는 순간에는 인지적 요인 외에 감성적 요인의 영향을 받는 것으로 판단된다.

Efficient Market Hypothesis (EMH), states that at any point in time in a liquid market security prices fully reflect all available information. This paper presents a study of proving the hypothesis through daily Twitter sentiments using the hybrid approach of the lexicon-based approach and the naïve Bayes classifier. In this research we analyze the currency exchange rate movement of Indonesia Rupiah vs US dollar as a way of testing the Efficient Market Hypothesis. In order to find a correlation between the prediction sentiments from Twitter data and the actual currency exchange rate trends we collect Twitter data every day and compute the overall sentiment to label them as positive or negative. Experimental results have shown 69% correct prediction of sentiment analysis and 65.7% correlation with positive sentiments. This implies that EMH is semi-strong Efficient Market Hypothesis, and that public information provide by Twitter sentiment correlate with changes in the exchange market trends.

Purpose - This study is to classify quality characteristics of online environment-friendly agricultural products shopping malls into 6 categories and to empirically test their relationship with customer trust, perceived manageability, perceived utility and purchase intention. Research design, data, and methodology - This study targeted adults who have purchased ecofriendly agricultural production online malls for 4 weeks from September 3 to September 30, 2019. The survey type used was a structuralized self-report survey questionnaire made to meet the research purpose in 2019 as the time range. Out of 800 questionnaires, 500 copies are used after excluding surveys with insincere responses. Results - First, results to hypothesis 1, which was about independent variables and customer trust. Analysis showed that health, familiarity, platform reputation, reviews and product quality were found to have significant effect on customer trust; the hypothesis was adopted. On the other hand, system security did not affect customer trust significantly; it was rejected. Second, customer trust was shown to have significant effect on perceived manageability and perceived utility, so the hypothesis was adopted. Third, the hypothesis that perceived manageability moves onto perceived utility was adopted. Moreover, the hypothesis that perceived manageability moves onto purchase intention and the hypothesis that perceived utility moves onto purchase intention were adopted as well. Conclusions - Furthermore, the results of the study imply that it's imperative for online environment-friendly agricultural products shopping malls to consider their characteristics as the means to increase purchase intention of customers.

Purpose - Prior theories predict a negative correlation between stock liquidity and dividend payout propensity. We test this hypothesis by examining the sample Korean retail firms. Research design, data, and methodology - We construct four different types of stock liquidity measures and investigate how these stock liquidity variables affect dividend payout propensity by employing the logit regression model. The retail firms listed in the KOSPI and KOSDAQ markets are analyzed from 1990 to 2015. Results - Our estimation results support the liquidity hypothesis if we adopt the stock turnover rate as the stock liquidity measure, particularly for the retail firms listed in the KOSPI markets and for non-conglomerate firms. Yet, our estimation results adopting the illiquidity measure of Amihud (2002), the proportion of non-trading day, and the volume of trading do not support the liquidity hypothesis. Conclusions - Our findings provide mixed results for the validity of stock liquidity hypothesis, which enriches the existing literature. In terms of turnover rate, the stock liquidity hypothesis holds robustly. Yet, we are not able to find any empirical evidence supporting the hypothesis if we use the other three measures of stock liquidity.

The human resources play an important role in a hotel cooking department. The object of this study is to gain basic data for searching an effective human resources management method of cooking department in the hotel. To achieve this object, I proceeded like this. In the second chapter, I exerted myself to arrange the theoretical system on the content of the human resources management through an internal and external philological research. In the third chapter, I established conceptional research model to study factual research and three hypotheses. And I made all high-grade hotel cooking employee in Taegu and Kyung-Buk answer an questionnaire, so practiced interrelation analysis and dispersion analysis according to research hypothesis. The results are as follows. First, the result of hypothesis 1 was that three was rather a high interrelation between the human resources management factor of cooking department and its overall evaluation. Second, the result of hypothesis 2 was that three was a significant difference about the overall evaluation of cooking business management according to the position demographically. Third, the result of hypothesis 3 was that there was a significant difference according to the scholastic ability, position and the district of hotel in the demographical evaluation of human resources management factor. The limits of this study were that first, I defined the subject as the cook employee of high-grade hotel in Taegu and Kyung-Buk, second, I utilized partial variance among many variances affecting human resources management. Therefore after this study, these limits much be overcomed and multiple and scientific study must be accomplish. So human resources of cooking department in the hotel must improve more.
