This study was conducted to determine the elements that are required and that need improvement in the contents of dietary life education and the educational environment by analyzing the importance-satisfaction of a dietary life education program for dietary life education trainees. The results of the rank test for the satisfactory elements of dietary life education were in the order of competence of instructors, educational contents, time of education, educational environment and affordability of tuition. The importance-satisfaction analysis of the contents and construction of the dietary life education program showed that “suitable contents for the theme of the class”, “contents and construction of practice class”, “diversity of practice menu” and “diversity of educational contents” had high importance and satisfaction scores and therefore, could be maintained at their current levels. Meanwhile, “adequacy of class time” and “contents and construction of theory class” showed low importance and satisfaction scores, requiring a little effort. Whereas, “time and construction of group practice”, “structure of textbook for class” and “duration of course and number of classes” showed relatively low satisfaction compared to importance, requiring major efforts for improvement. Similarly, analysis of the lecture element from dietary life education showed that “professional lecture by instructors”, “lectures suitable for themes” and “lecture applicable in real life” had relatively low satisfaction compared to importance, requiring major efforts for improvement. In addition, analysis of the educational environment from dietary life education showed that “adequacy of lecture room space”, “cooking equipment”, “diversity of cooking utensils” and “sanitary condition of cooking utensils” also require major efforts for improvement. Therefore, dietary life education should not be executed with a simple delivery of knowledge but with both theory and practice classes to increase its application in real life, and active and specific efforts are required to nurture professional instructors and establish educational strategies.

The objective of this study was to investigate taste profiles and the correlation of Doenjang soup solution prepared with three different temperatures (5, 25, 45℃) and using an electronic nose (e-nose), electronic tongue (e-tongue), and descriptive analyses by trained panelists. A total of 17sensory attributes were generated from the descriptive analyses for the Doenjang soup solution. There were significant difference among the samples in the cooked soybean flavor, the cooked soybean odor, the soy sauce odor, the sweet odor, the sweet taste, and the sweet aftertaste attributes. The intensities of these sensory attributes tended to increase as the serving temperature of the Doenjang soup solution increased. There were seven volatile compounds detected by the electronic nose: ethanol, propanal, 2-methylpropanal, ethyl acetate, 3-methylbutanal, and beta-pinene. The intensities of the volatile compounds increased as the temperature of the Doenjang soup solution increased. On the other hand, the intensities of the basic tastes by the e-tongue decreased as the temperature of the Doenjang soup solution increased. In conclusion, the e-nose, e-tongue, and descriptive analysis results showed different correlations depending on the temperature of the Doenjang soup solutions.

2014년 2월 여객선의 타두재 상단 너트가 풀려 타가 작동하지 않은 사고가 발생하였다. 많은 여객과 화물의 이동을 목적으로 하는 여객선의 조타 장치 사고로 인한 인명사고는 통계에 의하면 2010~2016년 0명이지만 조타장치의 고장으로 선박의 요건인 이동성을 갖추지 못한다면 물살이 거센 해역이나 출입항 선박이 많은 협수로에서는 선박의 조종에 대한 제약으로 인명사고의 비율이 높은 전복 사고나 충돌 사고로 발전할 수 있다. “선박안전법” 및 관련 고시인 “강선의구조기준”에는 타판과 타심재의 체결에 관련된 내용은 기준화 되어 있으나 타 빠짐의 원인이 되는 상부 타두재와 너트의 체결에 대해서는 별도의 법령이 없다. 사고 이후 한국선급은 강선규칙 5편 제7장에 결합방법에 대해 개정을 하였다. 목포항과 주변 섬을 운항하는 여객선 12척에 대한 현장조사 결과 대부분 C형타 2개가 설치된 구조였으며, 체결방법으로는 9척이 용접에 의한 체결 방법을 적용하고 있었고 선박 자체적으로 예방 점검을 위해 체결 개소에 접근하기 어려운 구조로 되어 있었다. 1년에 한 번씩 타를 들어 올리거나 빼내야 하는 여객선의 특성을 고려하여 동종 사고를 방지할 수 있는 방안에 대해서 NAS 3350 시험을 통해 검토하였다.

We examined the characteristics of indium tin zinc oxide (ITZO) thin film transistors (TFTs) on polyimide (PI) substrates for next-generation flexible display application. In this study, the ITZO TFT was fabricated and analyzed with a SiOx/ SiNx gate insulator deposited using plasma enhanced chemical vapor deposition (PECVD) below 350℃. X-ray photoelectron spectroscopy (XPS) and secondary ion mass spectroscopy (SIMS) results revealed that the oxygen vacancies and impurities such as H, OH and H2O increased at ITZO/gate insulator interface. Our study suggests that the hydrogen related impurities existing in the PI and gate insulator were diffused into the channel during the fabrication process. We demonstrate that these impurities and oxygen vacancies in the ITZO channel/gate insulator may cause degradation of the electrical characteristics and bias stability. Therefore, in order to realize high performance oxide TFTs for flexible displays, it is necessary to develop a buffer layer (e.g., Al2O3) that can sufficiently prevent the diffusion of impurities into the channel.

This study investigated the chemical composition of burdock (Arctium lappa L.) leaves essential oil, and the quantitative changes of the major terpene compounds according to the specific harvesting season. The essential oils obtained by the hydrodistillation extraction (HDE) method from the aerial parts of the burdock leaves were analyzed by gas chromatography (GC) and GC-mass spectrometry (GC-MS). The essential oil composition of this plant was characterized by the higher content of phytol and 6,10,14-trimethyl-2-pentadecanone. Seventy seven (98.28%) volatile flavor compounds were identified in the essential oil from the burdock leaves harvested during the spring season of 2012, and phytol (33.47%) and 6,10,14-trimethyl-2-pentadecanone (32.47%) were the most abundant compounds. Eighty eight (99.08%) compounds were identified in the essential oil from the leaves harvested during the autumn season of 2012, and in this case, phytol (37.35%) and 6,10,14-trimethyl-2-pentadecanone (34.67%) were also the most abundant compounds. These two volatile components were confirmed as the major oil components of the burdock leaves during the time of any harvest. The ratio between the two components contained in the burdock essential oils did not differ significantly by harvesting season. But overall, the essential oil harvested during the spring season contained 65.94% of the two major components, while for the essential oil harvested during the autumn season, the total amount of these two major components was 72.02%. While the main ingredients of the essential oils were found to be unchanged from one harvest time to the next, it was found to differ in content. For the burdock leaves, the quality index of the volatile constituents according to the harvest time would be more useful for utilizing the total quantity other than the proportion between phytol and 6,10,4-trimethyl-2-pentadecone.
