본 연구는 의료기관 동일조직 내에서 인적자원관리 개별 활동들을 묶음(bundles) 형태로 보는 포괄적 접근법으로 병원조직의 인적자원관리 효율화를 위한 관리방안을 파악해 보고자 하였다. 인적자원관리 개별제도의 합인 인적자원관리의 포괄적 접근법에 의한 평균을 기준으로 평균이상의 집단과 평균미만의 집단으로 구분하여 인적자원관리 개별제도를 이용하여 집단분류 한 결과, 소속집단 판별에 이용되는 인적자원관리 개별제도는 직종에 따라 다소 차이가 있었다. 그러나 인적자원관리 개별제도 중 '경력개발기회 제공 및 경영정보 공개' 제도는 모든 직종에서 유의하게 판별함수에 포함되는 변수이었다.

현재 HCM 신호교차로의 운영평가는 차로군 단위로 이루어져 차로별 고유 특성을 일반화하여 실제교통류 특성을 반영하지 못하는 경우가 발생한다. 본 연구에서는 별도의 추가적인 자료수집을 요구하지 않고 현 HCM 분석방법과 관련 software를 활용하여 신호교차로 운영을 차로별로 분석하는 단계별 절차를 제시하였다. 차로별 분석결과는 현재 HCM 차로군 분석결과와 차로별 분석이 가능한 호주 HCM 분석방법을 따르는 aaSIDRA의 결과와 비교분석하였다. 차로별 분석방법은 현 HCM 방법에 비해 HCM 지체도 산정공식중 증분지체의 민감도에 따른 영향으로 미미하게 높은 지체도를 보였다. 포화도와 대기행렬길이 등의 부가적인 효과척도는 두 방식이 유사한 결과를 보였고 aaSIDRA와의 결과비교에서는 비보호좌회전차로의 분석결과를 제외하고는 유사한 결과를 보여주었다. 본 연구에서 제안한 차로별 분석방법은 보다 미시적인 신호교차로 분석을 통해 현 분석 방법의 취약점을 보완할 수 있을 것으로 기대한다.

콩 발아기간 중 몇 가지 면역활성제(자스몬산, 키토산, 베타글루칸 및 게르마늄)와 녹차 및 인삼 추출물이 이소플라본 함량 증대에 미치는 영향에 대하여 알아보았다. 1. 대부분의 처리에서 발아시간이 경과함에 따라 이소플라본 함량이 높아졌는데 면역활성제 중에서는 키토산 처리가 이소플라본 함량 증대에 가장 큰 효과가 있었으며 약초추출물 처리는 효과가 미미하였다. 2. 품종별 이소플라본 함량은 모든 처리에서 대풍2호>우람>풍산나물콩의 순서로 높았으며 이소플라본 함량은 품종과 biotic 물질 처리간 상호작용도 영향을 미치는 것으로 판단된다. 3. 개별 이소플라본 종류별 함량을 분석한 결과 malonyl-glucoside>glucoside>aglycone>acetyl-glucoside 순서로 함량이 높았으며 발아가 진행되면서 aglycone 함량이 증가하는 경향이었다. 따라서 콩 발아기간 중 biotic 물질 처리는 어느 정도 이소플라본 함량을 증대시키며 품종과 물질처리간 상호작용 효과도 있음을 확인할 수 있었다.

The problem of detecting individual differences of chemically similar liquids remains to be unsolved for various areas of the natural sciences, such as medicine, biology, nutrition, and cosmetics 1. This problem is of crucial importance for the cosmetic sciences, including perfumery and aromatherapy. For example, some certain subtle differences of smell and taste between chemically similar liquids are very difficult to detect by using conventional methods of analysis, such as gas chromatography (GC) and the like (except under unique advanced techniques that are expensive, time consuming, and are not readily available). However, a trained human nose and! or mouth of a perfumer and/ or taster can detect differences of that kind. There are two conventional ways to make a fragrance.(omitted)

In this study, the perceptions of science classroom climate were investigated for 360 elementary and middle school students in mixed classes. The instrument used was an adapted version of the Student Perception Questionnaire (SPQ), which consists of five elements-Participatory Climate, Personalized Interaction, Student Assertiveness, Positive Teacher, and Negative Teacher. The results indicated that the gender differences in the perceptions of the Participatory Climate and the Positive Teacher were not significant for middle school students. However, the differences were found to be significant in the perceptions of the Negative Teacher, the Personalized Interaction and the Student Assertiveness, which measure the climate for the individual student. On the other hand, elementary male and female students did not significantly differ in the perceptions of science classroom climate except one item on the Participatory Climate. Educational implications are discussed.

We aimed to see if approach-avoidance visual experience would have different effects in the valence rating of emojis. Previous literature has shown that approach-avoidance tendencies have influences people's emotional perceptions. Up until now, research on emojis have been heavily focused on static emojis, which gives room for exploration whether if movement added on to emoji would elicit different emotional responses. In the study, we examined the impact of approach-avoidance visual experience of emojis via mobile interface, categorized into 4 experimental conditions (positive approach, negative approach, positive avoid, and negative avoid), and conducted semi-structured interviews to identify users' reasonings towards their valence ratings on specific emojis with approach or avoid movements. We found that positive approach emojis were the highest valence rating and preferred by the participants, while there were no differences between negative emoji approach or avoidance. Based on these findings, we conclude that positive emojis could be intensified to be more positive with approach motion, yet for negative emojis, individual differences or contextual differences may arise in its emotional ratings.

To clarify the relationship between the timing and the duration of flowering among populations, plants, and individual flowers, the dates of flower budding, flowering and deflowering were monitored for ten woody species from March 1 to June 30, in 2005, 2006 and 2007, in temperate deciduous forests at three sites of Namsan, and individual plants from seven woody species were monitored from March 1 to May 31, in 2006. Total durations of flower budding, flowering, and deflowering varied among the plant species. Three durations of these phenological stages of Stephanandra incisa were the longest (74 days, 109 days, and 101 days, respectively), and those of Prunus serrulata var. spontanea were the shortest (7 days, 7 days, and 4 days, respectively). For each species, phenological durations varied among years but were similar among the study sites in the same year. There was no relationship between flowering time and flowering duration on the population level. On the plant level, the duration of flower budding was over 11 days in all specie; S. incisa had the longest duration (73.3 days), and that of Styrax japonica was long as well (29.0 days), while that of Prunus leveilleana was the shortest (11.3 days). The longer the mean flower budding duration, the greater the difference among the plants within a species. The flowering duration of for S. incisa was 92.2 days, while that of Forsythia koreana was 27.2 days. The flowering durations of all other species were $10{\sim}20$ days. The deflowering duration was 92.0 days in S. incisa and <15 days in all other species. Differences among the plants in deflowering duration were smaller than those of the other phenological stages. In the species that flowered in April, the correlation coefficient between the flowering duration and the first flowering date was negative and significant. However, in the species that flowered in May, the correlation between flowering duration and the first flowering date was not significant. For individual plants of all species except for S. alnifolia, the earlier the flowering time, the longer the flowering duration. Differences between flowering time and flowering duration across years were significant in six species.

Objective: This study aimed to investigate important human factors that should be considered when developing ultra-high definition TVs by reviewing measurement methods and main characteristics of ultra-high definition displays. Background: Although much attention has been paid to high-definition displays, there have been few studies for systematically evaluating human factors. Method: In order to determine human factors to be considered in developing human-friendly displays, we reviewed subjective and objective measurement methods to figure out the current limitations and establish a guideline for developing human-centered ultra-high definition TVs. In doing so, pros and cons of both subjective and objective measurement methods for assessing humans factors were discussed and specific aspects of ultra-high definition displays were also investigated in the literature. Results: Hazardous effects such as visually-induced motion sickness, visual fatigue, and mental fatigue in the brain caused by undesirable TV viewing are induced by not only temporal decay of visual function but also cognitive load in processing sophisticated external information. There has been a growing evidence that individual differences in visual and cognitive ability to process external information can make contrary responses after exposing to the same viewing situation. A wide vision, ultra-high definition TVs provide, can has positive and negative influences on viewers depending on their individual characteristics. Conclusion: Integrated measurement methods capable of considering individual differences in human visual system are required to clearly determine potential effects of super-high vision displays with a wide view on humans. All of brainwaves, autonomic responses, eye functions, and psychological responses should be simultaneously examined and correlated. Application: The results obtained in this review are expected to be a guideline for determining optimized viewing factors of ultra-high definition displays and accelerating successful penetration of the next-generation displays into our daily life.
