Members of the glycoprotein family, which includes CG, LH, FSH and TSH, comprise two noncovalently linked $\alpha$- and $\beta$-subunits. Equine chorionic gonadotropin (eCG), known as PMSG, has a number of interesting and unique characteristics since it appears to be a single molecule that possesses both LH- and FSH-like activities in other species than the horse. This dual activity of eCG in heterologous species is of fundamental interest to the study of the structure-function relationships of gonadotropins and their receptors. CG and LH $\beta$ genes are different in primates. In horse, however, a single gene encodes both eCG and eLH $\beta$-subunits. The subunit mRNA levels seem to be independently regulated and their imbalance may account for differences in the quantities of $\alpha$ - and $\beta$ -subunits in the placenta and pituitary. The dual activities of eCG could be separated by removal of the N-linked oligosaccharide on the $\alpha$-subunit Asn 56 or CTP-associated O-linked oligosaccharides. The tethered-eCG was. efficiently secreted and showed similar LH-like activity to the dimeric eCG. Interestingly, the FSH-like activity of the tethered-eCG was increased markedly in comparison with the native and wild type eCG. These results also suggest that this molecular can implay particular models of FSH-like activity not LH-like activity in the eCG/indicate that the constructs of tethered molecule will be useful in the study of mutants that affect subunit association and/or secretion. A single-chain analog can also be constructed to include additional hormone-specific bioactive generating potentially efficacious compounds that have only FSH-like activity. The LH/CG receptor (LH/CGR), a membrane glycoprotein that is present on testicular Leydig cells and ovarian theca, granulosa, luteal, and interstitial cells, plays a pivotal role in the regulation of gonadal development and function in males as well as in nonpregnant and pregnant females. The LH/CGR is a member of the family of G protein-coupled receptors and its structure is predicted to consist of a large extracellular domain connected to a bundle of seven membrane-spanning a-helices. The LH/CGR phosphorylation can be induced with a phorbol ester, but not with a calcium ionophore. The truncated form of LHR also was down-regulated normally in response to hCG stimulation. In contrast, the cell lines expressing LHR-t63I or LHR-628, the two phosphorylation-negative receptor mutant, showed a delay in the early phase of hCG-induced desensitization, a complete loss of PMA-induced desensitization, and an increase in the rate of hCG-induced receptor down-regulation. These results clearly show that residues 632-653 in the C-terminal tail of the LHR are involved in PMA-induced desensitization, hCG-induced desensitization, and hCG-induced down-regulation. Recently, constitutively activating mutations of the receptor have been identified that are associated with familial male-precocious puberty. Cells expressing LHR-D556Y bind hCG with normal affinity, exhibit a 25-fold increase in basal cAMP and respond to hCG with a normal increase in cAMP accumulation. This mutation enhances the internalization of the free and agonist-occupied receptors ~2- and ~17-fold, respectively. We conclude that the state of activation of the LHR can modulate its basal and/or agonist-stimulated internalization. Since the internalization of hCG is involved in the termination of hCG actions, we suggest that the lack of responsiveness detected in cells expressing LHR-L435R is due to the fast rate of internalization of the bound hCG. This statement is supported by the finding that hCG responsiveness is restored when the cells are lysed and signal transduction is measured in a subcellular fraction (membranes) that cannot internalize the bound hormone.

Five experiments were conducted using finishing pigs (PIC L326 sires $\times$ C15 dams) to examine the effects of expander operating conditions on nutrient digestibility in finishing pigs. The effects of different expanding conditions (0, 11.7, 24.4, $32.5kg/cm^2$) for corn-SBM based diets (Exp. 1), wheat meddlings diet (Exp. 2), sorghum-SBM based diets (Exp. 3) and wheat-SBM based diet (Exp. 4). Exp. 5 was conducted as a $2{\times}4$ factorial arrangement and factors examined were 2 soy products (raw soybean and SBM) and 4 expanding conditions (0, 14.1, 28.1, $42.2kg/cm^2$). In experiment 1, total production rates (p>0.10) were similar among treatments. The amount of fines decreased (cubic effect, p<0.001) as cone pressure was increased from 0 to $11.7kg/cm^2$, with smaller differences as cone pressure was further increased to $35.2kg/cm^2$. Nutrient digestibilities increased (p<0.02) as the feed was subjected to higher cone pressures. Digestibilities of DM, N, and GE were maximized at $24.4kg/cm^2$ cone pressure. The DE of the diet expanded at 24.4 and $35.2kg/cm^2$ increased by 172 and 109 kcal/kg, respectively, compared to the diet processed at $0kg/cm^2$ cone pressure. In experiment 2, total production and screened pellets production rates were similar among the processing treatments (p>0.21). The amount of fines decreased (quadratic effect, p<0.03) by 9 kg/h as cone pressure was increased from 0 to $11.7kg/cm^2$. Digestibilities of DM (p<0.02), N (p<0.001), and GE (p<0.002) were increased as cone pressure was increased from 0 to $35.2kg/cm^2$. DM, N, and GE digestibility in the pigs fed the midds-based diet increased by 8, 13, and 10%, respectively, at the highest processing cone pressure compared to the diets without any cone pressure. In experiment 3, the conditioned mash moistures for the treatments were numerically similar around 15% moisture. As the expander cone pressure was increased from 0 to $11.7kg/cm^2$, energy consumption for the pellet mill decreased (quadratic effect, p<0.004) from 14.1 to 12.0 kWh/t. Dry matter and gross energy digestibility increased (cubic effects, p<0.006) as cone pressure was increased from 0 to $35.2kg/cm^2$ with the largest improvement occurring as cone pressure was increased from 0 to $11.7kg/cm^2$. Nitrogen digestibility increased (cubic effect, p<0.001) from 78.3 to 81.0% as the feed was subjected to the higher cone pressures, with N digestibility being maximized at $24.4kg/cm^2$ cone pressure. The DE of the diet increased (cubic effect, p<0.001) by 225 kcal/kg as cone pressure was increased from 0 to $11.7kg/cm^2$. In experiment 4, pellet moisture decreased and moisture loss increased as cone pressure was increased from 0 to $35.2kg/cm^2$. Also, starch gelatinization of the wheat-based diets increased from 16.8 to 49.1% as the diets were processed at 0 and $35.2kg/cm^2$ cone pressure. Nutrient digestibilities were not affected (p>0.18) by any increase in cone pressure. In experiment 5, pellet moisture decreased as cone pressure was increased 0 to $35.2kg/cm^2$. The amount of moisture loss for the diets expanded at $42.2kg/cm^2$ was 3.0 and 3.8% for the SBM and raw soybean (RB) diets, respectively. Starch gelatinization for the SBM diets were 19% greater than the RB diets. The RB diets had lower DM, N and GE digestibilities as compared to the SBM diets. The DE of the RB diets were lower (p<0.02) than the SBM diets. DM (p<0.06), N (p<0.02), and GE (p<0.001) digestibilities of the dietary treatments increased as cone pressure was increased 0 to $42.2kg/cm^2$.

The Immersion Grating Infrared Spectrometer (IGRINS) is the first astronomical spectrograph that uses a silicon immersion grating as its dispersive element. IGRINS fully covers the H and K band atmospheric transmission windows in a single exposure. It is a compact high-resolution cross-dispersion spectrometer whose resolving power R is 40,000. An individual volume phase holographic grating serves as a secondary dispersing element for each of the H and K spectrograph arms. On the 2.7m Harlan J. Smith telescope at the McDonald Observatory, the slit size is $1^{{\prime}{\prime}}{\times}15^{{\prime}{\prime}}$. IGRINS has a plate scale of 0.27" pixel-1 on a $2048{\times}2048$ pixel Teledyne Scientific & Imaging HAWAII-2RG detector with a SIDECAR ASIC cryogenic controller. The instrument includes four subsystems; a calibration unit, an input relay optics module, a slit-viewing camera, and nearly identical H and K spectrograph modules. The use of a silicon immersion grating and a compact white pupil design allows the spectrograph collimated beam size to be 25mm, which permits the entire cryogenic system to be contained in a moderately sized ($0.96m{\times}0.6m{\times}0.38m$) rectangular Dewar. The fabrication and assembly of the optical and mechanical components were completed in 2013. From January to July of this year, we completed the system optical alignment and carried out commissioning observations on three runs to improve the efficiency of the instrument software and hardware. We describe the major design characteristics of the instrument including the system requirements and the technical strategy to meet them. We also present the instrumental performance test results derived from the commissioning runs at the McDonald Observatory.

The purpose of this study was to investigate the status of the problematic behavior for the demented elderly and the stress among family members, and the effects of the problematic behavior upon the stress in order to offer the basic data for the adult and the elderly health education about dementia. For this purpose, 70 families who were resident in Seoul and Inchon were surveyed by quetionnaires. This was carried out from 26 July, 1994 to 11 September, 1994. Datum was analysed by using SPSS\PC+ including percentage, mean, t - test, ANOVA, Pearson correlation. So, the results of this study were as follows: 1. In view of socia-demographic characteristics, female were 82.9%, and of the female daughters-in-law of the demented elderly were 44.9%. 40th years old were 32.9% and 88.6% wase married. The christian were 34.8%, those who graduated university 47.1%, and those who had a job 32.9%. 2. Of the demented elderly, female were 74.3%, 80 years old were 37.1%, and their average age was seventy-seven point one years old. 66.2% of the elderly has been lived alone and the christian were 27.5%. In addition, those who graduated elementary school were 66.5%. 3. Of the behavior problem for the demented elderly, Activities of the Daily Living(ADL) was the most severe problem. The 2nd was cognitive function problem, the 3th, change of personality, the 4th, emotional disturbance, and the last, misconduct behavior. 4. For the status of behavior problems, females were more severe than male, and 80th years elderly ware the most severe groups. The longer disease period was, the severe problematic behaviors were, and in 4-6 years of the disease period the status was the highest(p＜0.05). Those who diagnosed the disease had more severe problems(p＜0.001). 5. The orders of the stress among family members caring for the demented elderly in this study were as follows : 1. The deficiency of supporting network 2. Decrease of elderly's cognitive activities 3. Assistance of BADL(Basic Activities of Daily Living) 6. Elderly's abnormal behavior 5. Assistance of IADL(Instrumental Activities of Daily Living), 6. As for the status of the stress among family members, female respondants were higher than male. On the ages, 20th years' stress score were the highest. Daughters-in-law were stressed more than other family members. The longer the time of caring per day was, the highest the status of the stress(p＜0.05), 7. Those who caring for female elderly and more than 80 years had more stressed. When the elderly was received the diagnosis, the family members were more stressed. On the disease period, 1-2 years was the highest and after 2 years the status of the stress was decreased and more than 6 years was the lowest(p＜0.05). 8. Behavior problems of the demented elderly were closely associated to the stress for family members. Of the problems, change of personality was the most related factor(r = 0.6552). The factors of Basic Activities of the Daily Living(BADL) was most correlated on assistance of Basic Activities of Daily Living (BADL), emotional disturbance the assistance of IADL(Instrumental Activities of Daily Living). Change of personality was most related to the stress of the decrease of cognitive activities and elderly's abnormal behavior. The deficiency of supporting network was most related to misconduct behavior.

서울시 간선축자전거도로의 경우 한강변을 중심으로 축이 형성되어 있어 이용자가 많은 한강변 주변에 거주자들의 이용이 높은 반면, 도심지역 거주자들의 한강변자전거도로의 이용도는 낮다. 이는 한강변자전거도로를 연결하는 자전거도로와 도심지역의 자전거도로와의 연계성이 떨어지는 것으로 판단되며, 한강이남자전거도로의 접근성을 높이기 위한 정책보다는 시설위주의 정책을 시행하고 있다. 한강변자전거도로의 이용만이 아닌 서울시 자전거도로의 연계성을 높이기 위한 합리적인 개선책이 필요한 시점이라 할 수 있다. 본 연구의 목적은 한강이남자전거도로를 대상으로 자전거도로의 접근성을 분석하기 위하여 한강이남지역의 공간구조를 Space Syntax Model을 이용하여 현재 및 자전거간선축설치계획 후와 일반도로설치 후를 비교하여 강서 강동지역간의 연계성을 분석하고, 그에 따른 변화를 예측하는 것이다. 본 연구에서 사용된 주요 분석방법은 Space Syntax Model을 이용한 한강이남자전거도로의 특성을 분석하였다. 결과적으로, 강서 강동지역간 자전거도로 연결 시 한강이 남자전거도로의 접근성은 향상하였으나, 공간구조명료도($R^2$)는 낮아지는 것으로 나타나 현재에 비해 지역 전체에 예측률이 낮다고 할 수 있다. 이는 현재의 한강이남자전거도로와 간선축 설치계획안 일반도로설치안 비교 시 상대적으로 가장 높은 공간구조명료도를 나타내어 자전거도로가 지역 간 연결이 이루어지기 전인 도로형태이기 때문인 것으로 분석되었다.

전라남도 연안에서 대량 생산되고 있는 해조류 5종(다시마 미역 김 파래 톳)을 대상으로 새로운 추출방법인 아임계 추출법을 도입하여 기존의 추출방법(열수, 용매추출)과 비교를 통하여 전남산 해조류의 기능성 측정 및 효율적인 추출물에 대한 자료를 확보하기 위해 조사를 실시하였다. 해조류 추출물 제조는 열수($80^{\circ}C$, 4시간), 용매추출(methanol, ethanol, 실온, 4시간)과 아임계 추출(압력 3 MPa, 온도 90, 150, $210^{\circ}C$)을 이용하여 제조하였다. 추출 수율은 아임계 추출＞열수 추출＞용매 추출 순으로 높게 나타났으며, 아임계 추출의 경우 추출 온도 조건이 높아지면서 수율 또한 증가하였으며 $210^{\circ}C$에서 가장 높은 수율 결과를 나타냈다. 해조류 추출물의 총당 분석 결과 열수와 용매 추출의 경우 모든 시료에서 열수 추출이 높은 총당 함량을 보였으며, 아임계 추출의 경우 모든 조건(90, 150, $210^{\circ}C$)의 추출물이 용매 추출보다는 높은 총당 함량을 보였다. 시료별 총당 함량의 경우 열수 추출물은 파래, 김, 톳, 미역, 다시마 순으로 당 함량이 높았으며, 이러한 결과는 아임계 추출의 경우에서도 동일한 결과를 보였다. 환원당 분석 결과도 총당 결과와 유사하였다. 5종 해조류 추출물의 총 폴리페놀 함량은 $210^{\circ}C$ 아임계 추출물＞ $150^{\circ}C$ 아임계 추출물＞ $90^{\circ}C$ 아임계 추출물＞열수 추출물＞methanol 추출물＞ethanol 추출물 순으로 높게 나타났다. 해조류 추출물의 DPPH radical 소거능을 측정한 결과, 모든 해조류 시료에서 열수 추출, 용매 추출, 3 MPa, $90^{\circ}C$ 아임계 추출물의 $SC_{50}$ 값은 서로 유사한 결과를 보였으며, $150^{\circ}C$ 아임계 추출물의 경우 농도가 조금 낮아졌으며, 특히 $210^{\circ}C$아임계 추출물의 경우 $SC_{50}$ 농도가 현저히 낮아져 항산화 활성이 크게 증가하는 것으로 나타났다. 미백효과 실험을 위해 tyrosinase 저해 효과를 살펴본 결과 톳과 김이 가장 효과가 좋았으며 미역, 다시마, 미역귀 순으로 나타났고, 파래의 경우 거의 효과가 없는 것으로 나타났다. 결론적으로 새로운 추출방법인 아임계 추출법은 다른 방법에 비하여 높은 항산화 활성을 보여준다는 사실을 확인할 수 있었고, 이러한 추출공정은 식품소재로부터 기능성 성분을 보다 더 효과적으로 추출하는 방법으로 적용할 수 있을 것으로 판단된다.

본 연구에서는 국내에서 다소비 되는 십자화과 새싹채소 7종(콜라비, 적무, 브로콜리, 배추, 유채, 무순 및 다채)의 항산화 및 지방세포 내 ROS 생성 억제 활성을 측정하였다. 총 페놀 및 총 플라보노이드 함량을 측정한 결과, 총 페놀 함량은 콜라비 새싹과 무순 추출물이 $23.97{\pm}0.46mg\;TAE/g$ 및 $24.40{\pm}1.24mg\;TAE/g$으로 유의적으로 가장 높은 값을 나타내었고, 총 플라보노이드 함량은 무순 추출물이 $15.30{\pm}1.35mg\;CE/g$으로 다른 새싹채소 추출물에 비해 높은 값을 나타내었다. DPPH radical 소거능과 ORAC value를 측정한 결과, 콜라비가 DPPH radical 소거능($IC_{50}=1.95mg/mL$)과 ORAC value($79,032.5{\mu}M\;TE/g$)에서 모두 항산화능이 뛰어난 것으로 나타났다. 한편, 다채를 제외한 새싹채소 추출물 6종 모두에서 세포 내 ROS 생성량을 감소시킴을 확인하였다. 이상의 결과로부터, 십자화과 새싹채소 중 콜라비 새싹과 무순 추출물의 경우 항산화활성 및 지방세포 내 ROS 생성 억제 활성을 가지며, 천연물 유래 항산화 소재로써 활용 가능성이 높은 것으로 기대된다.
