본 연구는 EV 충전 인프라 구축에 따라 이용자들이 인프라에 대하여 실질적으로 개선되었 다는 효능감을 느끼고 있는지 검증을 통해 제주지역 EV 충전 인프라 구축정책에 대한 효과성 을 분석하는 것이 목적이다. 연구 결과로는 충전기에 대한 ‘설치의 충분성’, ‘이용의 신속성’, ‘관련 정보 파악의 용이성’, ‘고장 충전기의 신속 고객서비스 대응’과 같은 세부 만족 요인이 EV 충전 인프라 개선 효능감에 영향을 주는 것으로 나타났다. 아울러 이용자의 ‘주택유형’에 따른 ‘EV 충전 이용 만족’이 ‘EV 충전 인프라 개선 효능감’에 유의미한 영향을 미치는 것으로 확인되었다. 공동주택 거주 전기차 이용자들의 효능감 제고를 위한 충전 인프라 구축 필요성 도 도출되었으며, 전반적인 정책 효과성은 높은 것으로 확인되었다. 본 연구는 제주지역 사례 를 통해 전기차 충전 인프라 구축정책의 효과성을 검증하는데 기여할 수 있다. In this study, factors affecting the efficacy of EV charging infrastructure improvement were investigated for EV users on Jeju Island. This study analyzed satisfaction with the EV charging infrastructure and demographic factors that affect the efficacy of EV charging infrastructure improvement. Factors found to affect the efficacy of EV charging infrastructure improvement include a sufficient number of charger installations, the speed in using EV chargers, the ease of obtaining additional information about charging, and fast customer service for faulty chargers. It was also confirmed that demographic factors such as user’s housing types had a significant effect. This study contributes to verifying user satisfaction with the construction of EV charging infrastructure throughout Jeju Island.

본 연구는 전기차를 렌트한 이용자의 만족도가 전기차 구매에 어떠한 영향을 미치는지에 대한 검증을 목적으로 한다. 연구 결과, 전기 렌터카 이용 후 만족도와 유의미한 상관관계를 가지는 요인으로 성별, 연령, 정숙성 및 승차감, 충전 인프라가 확인되었으며, 연령, 정숙성 및 승차감, 충전 인프라 요인은 전기 렌터카 이용 후 만족도를 통해 전기차 구매 관심 및 의도에 영향력을 미치는 것을 확인할 수 있었다. 연구의 차별성은 전기차 체험을 통한 전기차 보급 견인의 주요 수단으로서 전기 렌터카에 초점을 맞추어 실증연구를 통해 분석했다는 측면과 전 기 렌터카를 통해 전기차를 처음 경험한 이용자들을 분석 대상으로 한정했다는 측면을 들 수 있다. The purpose of this study is to verify how the EV rent-a-car satisfaction affect the purchase intention of the EV. As a result of the study, Gender, Age, Quietness & Ride comfort, Charging infrastructure had a significant correlation with the EV rent-a car satisfaction level. and It is confirmed that the factors of Age, Quietness & Ride comfort, Charging infrastructure affect the EV purchase intention of the EV through the EV rent-a-car satisfaction level. The differentiation of the study is that it was analyzed through empirical research, focusing on the EV rent-a-cars as a major means of spreading the EV. also the analysis target was limited to first-time the EV’s Users through the EV rent-a-car.

The recent studies regarding a motor memory indicated that off-line learning results from a memory consolidation process occurring during a rest period after a practice session. According to memory consolidation theory the off-line learning effect is the result of two types of consolidation processes:1) sleep-dependent consolidation and 2) wake-based consolidation. The purpose of the present study was to examine what type of consolidation process was responsible for the off-line learning effect found in practice of a golf putting. Twenty four participants putted the ball toward the target 5m away. The performance score was actual distance (in cm) from the target. Participants putted 60 balls in the practice phase, 15 balls in the test and 15 balls in the retest. Participants were randomly assigned to one of two experimental groups according to whether sleep was included during 12-hr rest period. The sleep group performed the practice and test trials at 9 p.m., and the retest trials at 9 a.m next day. The no sleep group performed the practice and test trials at 9 a.m., and the retest trials at 9 p.m. The sleep group revealed significantly improved putting performance after a 12-hr rest. However, the no sleep group did not show a significant performance difference between the test and retest. These results suggest that off-line learning effect in practice of a golf putting results from a sleep-dependent consolidation process.

The purpose of this study was to investigate the effect of heel height on women's dynamic balance. Seven female subjects, aged 19-22 years, volunteered to participate for the study. The subject was asked to lean forward, backward and sideways and to reach as far as possible without moving the feet or bending at the hip, in a plane parallel with the measuring tape attached on the wall at shoulder height. Maximal antero, posterior, and lateral distance reached were measured to evaluate a dynamic balance. Subjects were tested in bare feet and 4 pairs of shoes. Shoes were women's dress pumps identical except for heel height. Heel heights were 3, 5, 7, and 9 cm. The results indicated that increasing heel height did not influence the maximum reach distance in the backward and sideway direction. However, the maximum reach distance in the forward direction decreased significantly with increasing heel hight. Post-hoc analysis revealed that the reach distance was significantly smaller in the 7 and 9 cm heel height. These findings suggest that heel height has a detrimental effect on women's dynamic balance. The poor balance derives from a decrease of postural stability in the forward direction. A critical heel height for producing balance hazards locates between 5 and 7 cm. Key words:heel height, dynamic balance, maximum reach distance.

배추흰나비(Pieris rapae)의 vetellogenin과 vitellin을 전기영동을 이용하여 확인하였고 gel slice로 vitellin을 정제하여 vitellin의 물리화학적 성질들을 조사하였다. Vitellin은 등전점이 6.10이고 탄수화물, 지질, 인 등이 결합되어 있는 복합단백질로 나타났다. Vitellin은 nondenatured-PAGE로 결정된 분자량은 $380,000{\pm}10,000$ dalton이고 각각 150,000과 40,000 dalton의 분자량을 가지는 두 종류의 크고 작은 소단위로 구성된 구조를 지니는 것으로 나타났다. Double diffusion test와 Tandem-crossed immunoelectrophoresis에서 vitellogenin과 vitellin은 면역학적 동질성을 나타냈다. Rocket immunoelectrophoresis로 vitellogenesis 기간중 혈림프의 vitellogenin과 난소의 vitellin을 정량분석한 결과 vitellogenin과 vetellin은 용화 6일째 처음 나타난 이후 계속적으로 증가하였다. Juvenile hormone I은 용화 4일째의 암컷 지방체에서 vitellogenin을 합성시키도록 유도하였다. Vitellin from the cabbage butterfly, Pieris rapae L., was purified and characterized by electrophoresis. Vitellin from P. rapae is a phosphorylated glycolipoprotein of molecular weight of $380,000{\pm}10,000$ as determined by the nondenaturing polyacrylamide gel electrophoresis. Two subunits with $M_r$ of 150,000 and 40,000 were obtained from vitellin. The native molecule is thought to be a tetramer composed of two molecules of each of these subunits. The isoelectric point, as determined by isoelectric focusing on polyacrylamide gels, is 6.10. Vitellin and vitellogenin were indistinguishable by immunological methods such as double diffusion and tandem-crossed immunoelectrophoresis. Vitellogenin from the hemolymph and vitellin from the ovary were quantified by rocket immunoelectrophoresis. Vitellogenin and vitellin were first detected in 6-day-old pupae and their levels increased continuously during ovarian development. Vitellogein synthesis by the fat body in 4-day-old female pupae could be induced by juvenile hormone I.

공간 다수준 분석을 이용한 부산지역 암발생 및 암사망 추정

고영규,한준희,윤태호,김창훈,노맹석,Ko, Younggyu,Han, Junhee,Yoon, Taeho,Kim, Changhoon,Noh, Maengseok 한국데이터정보과학회 2016 한국데이터정보과학회지 Vol.27 No.5

한국인의 전형적인 사망 원인인 암은 보건 분야에서 중요한 문제이다. 통계청이 제시한 Cause of death statistics (2014)에 따르면, 7대 광역시 중 부산의 표준화 사망률 (standardized mortality rate; SMR)이 가장 높게 나타났다. 이 논문에서는 부산지역암센터의 암등록자료를 이용하여 암발생률과 암사망률의 정도를 추정하고자 한다. 2003~2009년 자료를 대상으로 구/동과 같은 소지역 단위를 고려하였으며, 전체 암과 4대 주요암 (위암, 대장암, 폐암, 간암)에 대해 분석하였다. 공간 상관성을 고려한 공간 다수준 모형을 통해 모형 선택과 모수 추정을 수행하였다. 공간 효과에 대해서는 조건부 자기회귀 (conditional autoregressive; CAR)를 가정하였으며 WinBUGS를 이용하였다. 분석의 결과로 각 지역에서의 공간 효과를 어떻게 분석하고 해석하는지 제시하였다. Cancer is a typical cause of death in Korea that becomes a major issue in health care. According to Cause of Death Statistics (2014) by National Statistical Office, SMRs (standardized mortality rates) in Busan were counted as the highest among all cities. In this paper, we used data of Busan Regional Cancer Center to estimate the extent of the cancer incidence rate and cancer mortality rate. The data are considered in small areas of administrative units such as Gu/Dong from years 2003 to 2009. All cancer including four major cancers (stomach cancer, colorectal cancer, lung cancer, liver cancer) have been analyzed. We carried out model selection and parameter estimation using spatial multi-level model incorporating a spatial correlation. For the spatial effects, CAR (conditional autoregressive model) has been assumed.
