The objective of this study was to determine the perception of monosodium glutamate (MSG) contents in eating out menu and MSG symptom complex. Respondents in the Seoul area were surveyed from Feb. 10 to 20, 2014. The results are summarized as follows. The 51.3% of respondents were male and 48.7% of them were female. As for age, 73.5% of respondents were 20~24 years old. Favorite menu of respondents' eating out were Korean food (57.8%), Western food (17.6%), Fast food (9.5%), Japanese food (6.2%), Chinese food (5.2%). Male respondents favored Korean food (62.4%), Fast food (10.2%) and Western food (9.6%), but female respondents favored Korean food (53.0%), Western food (26.2%) and Fast food (8.7%). The 48.7% of respondents considered Chinese food containing high amount of MSG. A few respondents (18.6%) recognized to usage amount of MSG as consideration factor to select eating out menu. However, most respondents (55.2%) perceived harmful to take excessive amount of MSG contained food. The 37.9% of respondents had experience of MSG symptom complex after eating out. Respondents' self recognized MSG symptom complex were thirstiness (84.5%), drowsiness (55.7%), weakness (34.5%), nausea (30.2%), tightness (20.7%) and headache (14.7%). The 19.9% of respondents like MSG contained food. The reason for disliking MSG contained food were 'bad for health' (66.3%) and 'MSG symptom' (33.2%). The reason for liking MSG contained food were 'good taste (83.6%) and 'habitual eating' (14.8%). The result of this study showed that some sensitive people have unpleasant reaction after eating out. Therefore, it is suggested that natural flavor enhancer may develop to replace the use of MSG.

자기치유형 아스팔트를 구현하기 위하여 치유제로 디메틸페놀을 사용하여 내부층을 이루고 바깥층이 멜라민 수지로 이루어진 마이크로켑슐을 제조하였다. 마이크로캡슐이 내재된 아스팔트는 일반 아스팔트에 비해 높은 기계적 성질을 나타내었다. 그대로 길어질수록 마이크로캡슐이 함유된 아스팔트는 함유되지 않은 아스팔트보다 더 높은 충격 강도를 나타내었으며 15일의 휴식기간에 최초의 물성을 회복하였다. 이는 X-선 사진에서 보듯이, 깨어진 아스팔트 경계면에 있던 마이크로캡슐이 아스팔트와 동시에 깨지면서 캡슐 안에 있던 단량체인 디메틸페놀이 흘러나와 외부의 반응촉매 투입 없이 아스팔트 자체의 금속촉매와 아민촉매 및 공기 중의 산소분자에 의하여 열가소성 고강성 플라스틱 고분자인 폴리페닐렌옥사이드가 자율적으로 중합되면서 깨어진 아스팔트의 경계면을 메우면서 최초의 물성으로 복구된 것이다. 이는 마이크로캡슐을 함유한 아스팔트는 자가복구능을 갖고 있음을 의미한다.

본 연구는 지속가능한 개발(ESSD)에 있어 신도시 자족성의 의미를 이론적으로 고찰하고, 일산신도시를 사해로 자족성을 실증적으로 분석함으로써 자족성 제고를 위한 정책 방안을 계시하고자 하였다. ESSD의 관점에서는 자족시설을 이용하는 주민의 행태분석이 연구의 중심이 된다. 이에 따라 일산신도시외 토지이용계획의 특성을 살펴보고 통학시설, 통근시설 및 상업 서비스시설의 각 부문별로 자족성을 분석하였다. 일산신도시는 수도권정비계획법상 과밀억제권역에 속해 기본적으로 자족시설을 건설할 여건이 조성되어 있지 못하기 때문에 통근자족률은 21.8%에 불과하였다. 상업 서비스시설의 자족율은 89.4%에 달하나, 공공서비스시설의 자족성이 낮은 것으로 분석되었다. 통학시설자족률은 94.0%로 매우 높게 나타났다. 따라서 수도권 내 새로운 신도시외 조성이 필요한 경우 거리와 법적규제를 고려하여, 과밀억제권역을 벗어난 지역에서 입지를 모색할 것을 제안하였다. 자족시설에 있어서는 공업기능보다는 3차산업 중심의 자족시설 계획을 수립하는 것이 바람직하며, 3차산업의 신도시 유치를 위란 유인책을 마련하고, 유사한 기능끼리 특성화시피 집적이익을 추구할 수 있는 여건을 조성해 주어야 한다. 아울러 유관 정부기능이 입지하면, 이와 관련된 업무시설의 입지는 보다 쉽게 이루어 질 수 있을 것이다. 공공서비스시설 등 주민편익시설을 적기에 공급하기 위해 주택과 자족시설의 공급시기를 조절하면서 장기적 안목에서 신도시가 건설되어야 할 것이다.

Compulsive buyers are individuals who experience and routinely act on powerful, uncontrollable urges to purchase. The relationships that existed between compulsive buying behaviors among college undergraduates are associated with intended majors, self-esteem and fashion orientation for female college students between the ages of 18 and 24 were investigated. A random sample of 182 undergraduate students completed a questionnaire that contained measures of compulsive buying, self-esteem, and fashion orientation. Based on literature review, three hypotheses were proposed. For data analysis, descriptive statistics, t-test, Pearson Correlation, and Cronbach Alpha were used. The results found that the compulsive buying tendency is negatively related to self-esteem among college students among female college students. Also, the tendency toward higher levels of fashion-orientation was positively related to compulsive buying tendencies. Fashion major was more prone to have compulsive buying tendency when compared to business major. Based on these results, some implications for educators, marketers, consumers and would be suggested.

A propellant mainly consisting of nitric ester including nitrocellulose and nitroglycerine is characteristic of being decomposed naturally. And this phenomenon is known as being affected mostly by its storing temperature and humidity. In this research, the effect of storing temperature and humidity on self life has been studied by measuring the contained quantity of residual stabilizer of propellant KM30Al, which are parts of 155MM propelling charge K676 and K677; the method for the measurement is acceleration aging test, and decomposition reaction equation, Eyring Equation and Berthlot Equation were used for the calculation. As result of this study, it was found that the storing temperature influenced seven times as large as the storing humidity upon the self life of the propellant KM30Al, Furthermore, especially in the high temperature region, the storing temperature had a dominant effect on the self life.

For the poor observability of azimuth misalignment angle and east gyro drift rate of the traditional initial alignment, a bran-new SINS stationary fast self-alignment approach is proposed. By means of analyzing the characteristic of the strapdown inertial navigation system (SINS) stationary alignment seriously, the new approach takes full advantage of the specific force and angular velocity information given by inertial measurement unit (IMU) instead of the mechanization of SINS. Firstly, coarse alignment algorithm is presented. Secondly, a new fine alignment model for SINS stationary self-alignment is derived, and the observability of the model is analysed. Then, a modified Sage-Husa adaptive Kalman filter is introduced to estimate the misalignment angles. Finally, some computer simulation results illustrate the efficiency of the new approach and its advantages, such as higher alignment accuracy, shorter alignment time, more self-contained and less calculation.

Lycopersicon peruvianum shows a gametophytic self-incompatibility (GSI). GSI is controlled by a single locus (S locus) with multiple alleles. S ribonucleases encoded in S alleles cosegregate with their phenotypes of GSI in genetic cross. To understand the genetic role of S allele in L peruvianum, two large genomic fragments isolated previously were analyzed with total genomic DNAs from several tomato lines generated by cross-pollination. Southern blot analysis with the S allele fragments as probes revealed that the flanking region of S allele contained the highly homologous regions. It is speculated that they may play an important role to prevent genetic cross by self-pollination.

This study explored pre-service English teachers' participation in the development of a rubric and examined evaluation of their own English poetry. The current study would investigate: 1) the pre-service English teachers' perception as a rubric developer and self-evaluator, 2) the number of analytic area that the participants included in their rubrics and the scoring scheme that they designed in their rubrics, and 3) the inter-rater differences between self-assessemnt and expert-assessment across analytic areas. Twenty-four EFL learners participated in the current study. The researchers analyzed the learners' own English poetry, their field notes which contained the process of their writing, their rubrics, scores of self-assessment, and expert raters' scores. The results revealed that learners showed positive responses on learner-directed assessment, that 'content' is the most important area, and that inter-rater difference is small across all analytic areas.

A propellant mainly consisting of nitric ester including nitrocellulose, nitroglycerine and nitroguanidine is characteristic of being decomposed naturally. And this phenomenon is known as being affected mostly by its storing temperature. In this research, the effect of storing temperature on self life has been studied by measuring the contained quantity of residual stabilizer of propellant KM30A1, ignition powder and combustible cartridge case, which are parts of 155MM propelling charge K676 and K677; the method for the measurement is acceleration aging test, and decomposition reaction equation and Berthlot Equation were used for the calculation. The result of this research shows that propellant KM30A1, ignition powder, combustible cartridge case in order of decreasing self life, and the self life decreases to 1/3 as the temperature increases by $10^{\circ}C$.
