The purpose of this study was to examine the mediating effects of self-perceived competence on the relation between covert narcissism and dysfunctional anger expression of middle school students. The data collected from the questionnaire was analyzed by using the SPSS 20.0 program. The main results were as follows: Firstly, covert narcissism has statistically a significantly negative correlation to self-perceived competency. It also has a significantly positive correlation to dysfunctional anger expression. Secondly, the results revealed that the relation between covert narcissism and dysfunctional anger expression was partially mediated by 'physical appearance', 'behavioral conduct', 'social acceptance' and 'athletic ability' competencies. The result of this study is significant for providing the basic data for understanding the characteristics of the middle school students who have narcissistic tendencies due to a weak inner-self as well as helping their adaptational relationship through functional anger expressions.

The popularization of the Internet brought about easy access to a huge amount of information, yet it is hardly easy for one to find information in need. Therefore, information users must have information retrieval abilities to gather, analyze and utilize data in efficient ways. In general the information retrieval strategies of each user are all different, and consequently the retrieved result also significantly varies from one to another. This paper describes an experimental study on information retrieval behaviors in elementary students, and analyzes the variation in retrieval strategies and results by examining cognitive patterns based on their personal characteristics, specifically their cognitive patterns. As a research result we propose a set of education requirements which can improve students' information retrieval abilities and the efficiency of the information retrieval system.

This research is a descriptive study that aimed to identify the health knowledge related stroke, optimistic bias, and social support of middle-aged adults and the effect these had on their health-promoting lifestyle This study was conducted by collecting 220 adults aged between 40 to 60 years from C City D city and K city. Data were analyzed using descriptive analysis, ANOVA, t-test, Pearson's correlation coefficients and multiple regression with the SPSS 23.0 program. The average health-promoting lifestyle was 44.27 points. The health-promoting lifestyle of the study participants showed a positive correlation between the optimistic bias(r=.18, p=.001) and social support(r= .61, p<.000). According to the results of multiple regression analysis, perception of Necessity for Stroke Education(β=.12, p=.010), optimistic bias(β=.18, p=.040), and social support(β=.48, p<.000) were shown to be significant factors that affected the health-promoting lifestyle of the participants. These variables explained 38.5%. Therefore, an health education program to improve the health-promoting lifestyle related to stroke in adults should be considered as a way to enhance social support and reduce optimistic bias.

Substantial amounts of research have been accumulated by the attempt to use linguistic styles as the dependent measure in conducting psychological research. This research was condoned to develope a Korean text analysis program(KLIWC) based on the English text analysis program, LIWC(Linguistic Inquiry and Word Count), and the program reflects the Korean linguistic characteristics and culture that is related with language. We made it possible to analyze agglutinative phrase of many morphemes by linguistic tagging, and basic form dictionary and inflection rule were built. In addition, the face-saving weeds and emotional words were included as the analysis variables. The process of development and characteristics of Korean text analysis have been reviewed, and future direction for the improvement of the program has been discussed.

The purpose of this study was to analyze physics problem solving processes according to students' cognitive style in the area of 'Force and Motion' at high school level. Students who have already learned t e area of 'Force and Motion' during the first semester of the 10th grade have taken physics test and cognitive style test to choose students who have basic knowledge of physics and reflective or impulsive style. Four students who got over 19 points in the cognitive style test were selected as reflective students, and another four students who got below 12 points were selected as impulsive students. After explaining the purpose and procedure of this study, think-aloud method was introduced to the students, and the students practiced it. After that, the students solved three quantitative and qualitative problems each. Then, the questionnaire on the belief system on physics and physics problem solving and prerequisite knowledge test were also administered. By recording the students' problem solving processes, protocol was made and analyzed. After solving the problems, the students expressed their confidence, intimacy, and preference on each problem by the five point Likert scale. Impulsive students tended to succeed in solving more problems, less intimate, and more spontaneous and positive in seeking alternative solution when confronted with unacquainted problems. On the other hand, reflective students used more time in executing the problems even without planning, and used more time in solving problems and verification. Whether making effective plan or not was important rather than how much time they used in the planning step. In addition, repeating steps were more likely shown to impulsive students; they tended to be attached to their first idea.

The present study applied cognitive continuum theory to university environment in order to demonstrate that students' cognitive modes move along the continuum to be adaptive to the certain situation. This study also compared students' cognitive modes and the generally required modes in the university. The results showed that the students used corresponding cognitive modes to each subject even though they had different cognitive styles in general. It means that the students are adaptive to various tasks. And, the comparisons of the students' cognitive modes with the require4 modes in the university showed that the university tended to induce the students to use analytical cognitive modes. Therefore, the university faculty should be aware that they usually induce the analytical modes, and that they need to use various kinds of cognitive modes in order for the students to have adaptability and flexibility. However, the study did not demonstrate that the students would perform better when they fitted their cognitive modes into each subject.

We examined risk judgment and the accuracy of inference based on two kinds of probabilities in a Bayesian inference task: the death probability from a disease (base rates) and the probability of having a disease with positive results in the screening test (posterior probabilities). Risk information were presented in either a probability or a frequency format. In Study 1, we found a numerical format effect for both base rate and posterior probability. Participants rated information as riskier and inferred more accurately in the frequency condition than in the probability condition for both base rate and posterior probability. However, there was no frequency range effect, which suggested that the ranges of frequency format did not influence risk ratings. In order to find out how the analytic thought system influences risk ratings, we compared the ratings of a computation condition and those of a no-computation condition and still found the numerical format effect in computation condition. In Study 2, we examined the numerical format effect and frequency range effect in a high and a low probability condition and found the numerical format effect at each probability level. This result suggests that people feel riskier in the frequency format than in the probability format regardless of the base rates and the posterior probability. We also found a frequency range effect only for the low base rate condition. Our results were discussed in terms of the dual process theories.

Lipids extracted from two kinds of sun-dried laver samples, wild Porphyra suborbiculata and cultured Porphyra tenera, produced at Wan-do in Korea were studied. Dried P. suborbiculata contained $0.8\%$ total lipid(TL) which consisted of $21.4\%$ neutral lipid(NL), $53.4\%$ glycolipid(GL) and $25.2\%$ phospholipid(PL), and dried P. tenera contained $1.2\%$ TL which consisted of $30.5\%$ NL, $50.3\%$ GL and $19.2\%$ PL. Among the NL of dried P. suborbiculate and P. tenera, free fatty acid ($41.4\%,\;39.0\%$), triglyceride($25.6\%,\;28.8\%$) and free sterol ($22.1\%,\;16.7\%$) were predominant. Digalactosyl diglyceride ($34.7\%,\;46.6\%$) and monogalactosyl diglyceride ($19.2\%,\;18.0\%$) were the major components among the GL. Sulfoquinovosyl digylceride ($4.2\%$) was also identified in P. tenera only. And main lipids in the PL of P. suborbiculata and P. tenera were phosphatidyl ethanolamine ($40.3\%,\;35.7\%$) and phosphatidyl choline ($28.6\%,\;30.7\%$) and followed by phosphatidyl serine($15.1\%,\;19.2\%$) and phosphatidyl inositol ($16.0\%,\;14.4\%$). The major fatty acids in the TL of the dried P. suborbiculata were 20:5 ($29.4\%$), 16:0 ($23.4\%$) and 20:4 ($13.0\%$), and those of the dried P. tenera were 20:5 ($36.7\%$), 16:0 ($16.2\%$), 16:1 ($10.7\%$) and 18:1 ($9.7\%$). The fatty acid composition of the both samples in the NL fraction were similar to the pattern in those of the TL. The abundant fatty acids in the PL of the both dried laver were 20:5, 16:0 and 18:1. In case of the GL fraction, the main fatty acids of the dried P. suborbiculata were 16:0, 20:5, 18:1 and 20:4, while those of the dried P. tenera were 20:5, 16:0 and 18:1.

The purpose of this study is to analyze the factors of the main selection criteria of the contract form used to conclude the sales contracts of used ships and to assist parties in selecting the most suitable contract form for trading situations. The methods of the study are based on identifying the factors from the questionnaires using analytic hierarchy process analysis, following the selection of typical details through interviews with the S&P Broker Group and finding the solutions that match each detail. The analysis shows that ship traders prefer the Norwegian Sales Form (NSF) to NIPPONSALE for various reasons. Considering the sellers' situations, NFS is the more reasonable option for major countries, except Japan. NIPPONSALE is relatively more focused on the advantages of the buyer's conditions, including for Japan. It is important to select the appropriate clauses from these types of contract, according to the trading conditions, including the main and additional terms, in order to create a mutual agreement between the shipper and the consignee that leads to more cooperation and balances the purposes of both parties in adjusting the time for securing and disposing of the vessels.
