목적: 조명에 따른 동공 크기가 고위수차에 미치는 영향을 알아보고자 하였다. 방법: 안질환이나 전신질환이 없고, 기타 관련 수술 경험이 없는 평균연령 22.5±1.04세의 35명을 대상 자로 선정하여 수차를 측정하였다. i.Profiler plus 기기의 특성상 명소시 상태에서 설정된 동공 크기 ʻ3 mmʼ 를 명소시 유사 환경, 반암실 상태에서 설정된 동공 크기 ʻmaximumʼ을 박명시 유사 환경 상태로 가정하였다. 동공 크기와 등가디포커스와 등가착란원의 상관 분석을 실시하였다. 결과: 대상자의 동공 크기를 3 mm, maximum으로 나뉘어 고위수차를 측정하였을 때, RMS는 0.30±0.13 ㎛ 및 0.38±0.15 ㎛로 나타났다. 총 고위수차의 등가디포커스가 동공 크기 3mm에서 0.28±0.14 D와 maximum에서 0.41±0.16 D 이었고, 유의한 차이를 보였다(p=0.000). 동공 크기 3 mm와 maximum 에서 구면수차, 코마수차, 트레포일 수차의 등가디포커스의 차이는 각각 0.07 D, 0.04 D, 0.02 D 이었고, 구면수차(p=0.000) 및 코마수차(p=0.000)에서 유의한 차이가 있었다. 등가디포커스와 등가착란원 사이에서 유의한 양의 상관관계가 존재하였다(총 고위수차(R2=0.7045, p<0.01), 구면수차(R2=0.9376, p<0.01), 코마 수차(R2=0.8429, p<0.01), 트레포일수차(R2=0.7824, p<0.01)). 결론: 수차 측정 결과를 등가디포커스로 나타내어 교정이 필요한 정도를 디옵터로 표현할 수 있었다. 고 위수차의 교정이 고려되지 않았을 경우, 교정시력에 변화가 있을 것으로 예측되어 고위수차의 시각적 불편함에 대한 연구가 중요하다고 사료된다.

This paper aims to identify the impact on self-satisfaction of shopping tendencies and purchase behaviors for luxury goods. The research was conducted by survey method using questionnaires. The subjects of this study were female consumers from 20 to years old with a high pusrchasing capability for luxury goods. Using the statistics program SPSS 21.0, factor analysis, reliability analysis, one-way ANOVA, and multiple-regression analysis were executed. The analysis results are summarized below. For shopping tendency depending on ages, pleasure pursuit tendency showed insignificant difference in 40~50s, but significant difference in 20~30s. For the self-satisfaction, the interpersonal satisfaction showed the difference by age group, which was much higher in the respondents in 30~50s than those in 20s. Individuality pursuit tendency and rational shopping tendency had impact on self-satisfaction and rational shopping tendency on interpersonal satisfaction in 20s. Pleasure pursuit tendency and rational shopping tendency had impact on self-satisfaction and interpersonal satisfaction and pleasure pursuit tendency on the economic satisfaction in 30s. Pleasure pursuit tendency had impact on self-satisfaction and economic satisfaction and rational satisfaction on interpersonal satisfaction in 40s. Pleasure pursuit tendency and rational shopping tendency had impact on self-satisfaction and interpersonal satisfaction in 50s. High quality had impact on self-satisfaction and economic satisfaction and practicality on interpersonal satisfaction in 20s. High quality had impact on self-satisfaction and interpersonal satisfaction in 30s. High quality had impact on interpersonal satisfaction in 40s. High quality had impact on all elements of self-satisfaction for the respondents in 50s, practicality had negative impact on interpersonal satisfaction.

The large extracellular domain of glycoprotein hormone receptors is a unique feature within the G protein-coupled receptors (GPCRs) family. After interaction with the hormone, the receptor becomes coupled to Gs, which, in turn stimulates adenylyl cyclase and the production of cAMP. Potential phosphorylation sites exist in the C-terminal region of GPCRs. The experiments described herein represent attempts to determine the functions of the eel follicle-stimulating hormone receptor (eelFSHR). We constructed a mutant of eelFSHR, in which the C-terminal cytoplasmic tail was truncated at residue 614 (eelFSHR-t614). The eelFSHR-t614 lacked all potential phosphorylation sites present in the C-terminal region of eelFSHR. In order to obtain the eelFSHR ligand, we produced recombinant follicle-stimulating hormone (rec-eelFSHβ/α) in the CHO-suspension cells. The expression level was 2-3 times higher than that of the transient expression of eelFSH in attached CHO-K1 cells. The molecular weight of the rec-eelFSHβ/α protein was identified to be approximately 34 kDa. The cells expressing eelFSHR-t614 showed an increase in agonist-induced cAMP responsiveness. The maximal cAMP responses of cells expressing eelFSHR-t614 were lower than those of cells expressing eelFSHR-wild type (eelFSHR-WT). The EC50 following C-terminal deletion in CHO-K1 cells was approximately 60.4% of that of eelFSHR-WT. The maximal response in eelFSHR-t614 cells was also drastically lower than that of eelFSHR-WT. We also found similar results in PathHunter Parental cells expressing β-arrestin. Thus, these data provide evidence that the truncation of the C-terminal cytoplasmic tail phosphorylation sites in the eelFSHR greatly decreased cAMP responsiveness and maximal response in both CHO-K1 cells and Path-Hunter Parental cells expressing β-arrestin.

Phytochemical investigation of the sesame dregs of Sesamum indicum was conducted by open column and prep-HPLC chromatography. Two phytosterols (1 and 2) and two lignans (3 and 4) were isolated from the MeOH extracts of sesame dregs, and identified as β-sitosterol (1), daucosterol (2), sesamin (3), and sesamolin (4) by spectral analysis. Although these compounds were already isolated from sesame, it is important that they were still main phytochemical components in the sesame dregs.

High performance liquid chromatography (HPLC) was used for the analysis of chiisanoside in each stem and root of Acanthopanax senticosus collected from South Korea, North Korea, China and Russia. A reverse-phase system using a gradient of H2O and acetonitrile as the mobile phase was developed and detection was at 210nm. The analysis was successfully carried out within 30 min. Chiisanoside was measured in the stem and root of A. senticosus collected from various countries.
