Objective : This study was conducted to investigate the leisure activities and self-efficacy according to sensory processing feature of university students. Methods : The survey was conducted from March to June, 2018. A total of 235 university students in Jeolla and Gyeongsang area participated. We used Adolescent/Adult Sensory Profiles to investigate sensory processing feature, Leisure Activity Questionnaires to examine leisure activities, and Self-Efficacy Scale for self-efficacy. This study identified the frequency of leisure activities of university students, the frequency of leisure activities and self-efficiency according to the sensory processing feature, and the leisure activities according to the feature of sensory seeking. Results : For the frequency of leisure activities and self-efficacy according to sensory processing feature of university students, only sensory seeking showed significantly difference in the leisure activity frequency, and the self-efficacy was significantly difference according to the feature of all types of sensory processing (p<.05). In addition, this study identified that leisure activities according to the feature of sensory seeking showed a significantly difference in gym, watching TV, shopping, internet search and web surfing (p<.05, p<.01). Conclusion : According to sensory seeking feature of university students, leisure activities and self-efficacy showed a significant difference. In order to encourage leisure activities of university students and to improve their self-efficacy, an interventional approach based on an understanding of sensory processing characteristics will be needed.

반도체 및 디스플레이 공정등에서 고진공 및 급 배기 환경을 제공하기 위하여 사용되는 터보분자펌프 (Turbomolecular Pump, TMP)는 다층의 회전깃을 갖는 로터를 회전시켜 분자를 배출시키는 방식을 사용하는 진공펌프이다. 또한 최근에는 디스플레이 및 반도체 공정에서 높은 진공도뿐만 아니라, 높은 배기속도를 요구하는 추세에 따라, 터보 펌프와 드래그 펌프부분을 동시에 가지고 있어 상대적으로 작동 진공도 영역이 넓은 복합 분자펌프(Compound Turbomolecular Pump, CMP)의 활용도가 넓어지고 있다. 이러한 분자펌프가 장시간의 고속회전에 적합하고, 베어링에서의 오염을 없앨 수 있는 비접촉 방식인 자기부상 방식이 주로 적용된다. 자기베어링 시스템은 하드웨어와 소프트웨어로 나누어질 수 있는데, 하드웨어는 회전하게 되는 블레이드 로터 및 자기베어링 로터, 모터 로터 등이 포함된 축과 고정되어 있는 자기베어링 코어와 코일, 변위센서 등의 펌프 하우징 부분, 또한 이를 제어하기 위한 전력 증폭 시스템 등의 기전적인 요소들이 이루어져 있다. 소프트웨어라 할 수 있는 제어시스템에 있어서 자기 베어링이 불안정한 특성을 갖는 개루프계를 갖고 있으므로 안정화를 위한 능동제어 시스템이 필수적이며 진동제어 등의 기능을 갖도록 적용된다. 따라서 이러한 복합분자펌프의 성능은 이러한 시스템을 구성하는 개별 요소의 성능과 이를 통합한 제어시스템의 성능이 결정한다고 할 수 있다. 본 논문에서는 현재 개발중인 2,500 l/s급의 자기부상형 고진공 복합분자펌프의 시작품에 대하여 고속회전의 안정성에 대한 연구를 수행한 내용을 보고하고 있다. 디지털 제어시스템을 적용한 시작품의 최대 26,000 rpm까지의 고속회전시의 회전 응답 및 진동 특성을 측정 분석하였으며, 로터의 고유진동수 및 진동 모우드를 분석하였다. 또한 연속 작동시의 발열특성과 각 부분의 온도와 회전 안정성과의 관계를 평가하였다.

At the archaeological site, there are a variety of fired soil remains with which archaeomagnetic dating is measured, and there are also different kinds of kilns equipped with favorable plasticity conditions, so quality data can be gained. Among them, roof tile kilns indicate fairly great results of archaeomagnetic measuring. This should be associated with the properties of soil consisting of the kilns. With a lot of experimental results, it has been found that the fired soil samples of roof tile kilns have formed very stable residual magnetization. This author conducted archaeomagnetic research to present archaeomagnetic results of measuring about roof tile kilns from Goryeo in Gyeonggi. With the archaeomagnetic data of measuring 21 samples, this researcher tried to estimate the archaeomagnetic dating of roof tile kilns from Goryeo in Gyeonggi and divided them into three groups, group A (A.D.900~1150), group B (A.D.1150~1250), and group C (A.D.1300~1400) to figure out their relative order and arrange them in order. Through this kind of archaeomagnetic research, it will be possible to identify the dating of 21 roof tile kilns from Goryeo in Gyeonggi and also contribute considerably to chronological research on roof tile kilns from Goryeo. In the body, the remains and kilns belonging to each group are presented in detail.

This study examined resilience and career decision-making among specialized technical high school students with the aim of proposing preliminary data to suggest ways to improve self-efficacy in career decision-making through establishing proper resilience. The specific research questions were set as; first, to define the resilience status in relation to the students' personal characteristics among students; second, to describe the status of self-efficacy in career decision-making related to the students' personal characteristics among students; and last, to examine the influence of resilience on self-efficacy in career decision-making among specialized technical high school students. To accomplish such research objectives, the assessment survey was developed after reviewing the theoretical literature on specialized technical high school students' background, ego identity, and self-efficacy in career decision-making. The survey was comprised of 54 items including personal characteristics (3 items), resilience (27 items), and self-efficacy in career decision-making (24 items). A total of 990 students from industrial specialized high schools across the country completed the survey, and the responses from 775 students were used for the final analyses after excluding the surveys with unanswered items or untrustworthy responses. Results were as follows: The group with higher levels of school adaptation and satisfaction showed higher resilience and career decision-making than those with lower levels of school adaptation and satisfaction. Furthermore, for the influence of resilience on self-efficacy in career decision-making, the results showed that resilience had positive associations with self-efficacy in career decision-making, and all correlations and coefficients of determination showed a robust statistical significance. Therefore, to enhance self-efficacy in career decision-making, education that could help students better adapt to school, increase satisfaction with the school, and create positive resilience must precede.

본 연구에서는 전도성 분자로 잘 알려진 4,4-Di(ethynyl phenyl) -2'-nitro-1-(thioacetyl)-benzene(nitro - benzene) 분자를 Au (111) 표면에 자기조립하고, ultra high vacuum scanning tunneling microscopy (UHV-STM)을 사용하여 STM tip과 sample 사이의 거리를 변화시키면서 전기전도 특성을 측정하였다. Au 기판제작은 연증착시스템 (Thermal Evaporation System)으로 제작하였으며, piranha 용액 ($H_{2}SO_{4}\;:\;H_{2}O_{2}$=3:1)을 사용하여 전치리한 후, 자기조립 단분자막 (SAMs)을 형성하였다. 먼저 1-octanethiol을 ethanol solution용액 1 mM/L 농도에서 24시간 동안 자기조립한 후에, ethanol를 solution 용액으로 이용하여 nitro-benzene를 0.1 nM/L 농도로 암실에서 30분간 자기조립 하였다. 자기조림 후 solution을 제거하기 위해 에탄올로 세척하여 $N_2$로 건조시켰다. 이 조건하에서 UHV-STM을 사용하여 nitro-benzene SAMs의 실시간 모폴로지의 변화에 따른 nitro-benzene의 전기전도 특성을 STM tip - SAMs - Au 기판의 수직구조로 STM tip과 nitro-benzene의 거리를 변화시키면서, tunneling current을 조사하였다. 측정 결과 Z-position 변화에 대한 tunneling current와 resistance의 변화를 확인할 수 있었다.
