$Na_2CO_3$. Sodium orthosilicate (Na-OSi), Tetronix T-701 (T-701), Na-dioctyl sulfosuccinate (303C), Newpol PE-68 (PE-68), MJU-100A, and tetrasodium pyrophosphate were blended to prepare high performance alkaline cleaning agents (ACASs). The results of cleaning test with steel specimen showed that ACAS-6 ($Na_2CO_3$ 50g/Na-OSi 35g/T-701 20g/303C 18g/PE-68 17g/MJU-100A 10g/TSPP 20g/ water 180g mixture) had a good cleaning power. The cleaning power for press-rust preventing oil was 98% and 99% degreasing at 4wt%, $70^{\circ}C$ and $90^{\circ}C$, respectively ; for quenching oil, the cleaning power of ACAS-6 was 91% degreasing at 4wt% and $70^{\circ}C$. The foam heights measured immediately after foaming by Ross & Miles method and Ross & Clark method at 6wt%, $60^{\circ}C$ were 18mm and 65mm, respectively. It was concluded that ACAS-6 had a good low foaming cleaning agent.

Guinea pigs were fed a hypercholesterolemic diet (0.25 g/100 g cholesterol) and randomly allocated either to a Control group (n = 9) or to a Lutein (0.1 g/100 g) group (n = 10) for 12 weeks to evaluate oxidative stress and inflammation in both liver and eyes. Malondialdehyde (MDA) concentrations and inflammatory cytokines were measured as well as hepatic nuclear factor-kappaB (NF-${\kappa}B$) binding. Lutein concentrations were greater in eyes ($P$ < 0.01) and liver ($P$ < 0.001) in the Lutein group. All guinea pigs had high concentrations of hepatic cholesterol as well as high plasma ALT and AST levels indicative of liver injury. However, the Lutein group had 43% lower hepatic free cholesterol than the Controls ($P$ < 0.05). Hepatic MDA and MDA in the eye were lower in the Lutein compared to the Control group ($P$ < 0.05). Hepatic tumor necrosis factor-${\alpha}$ was 32% lower in the Lutein group ($P$ < 0.05). Lastly, the Lutein group presented lower NF-${\kappa}B$ DNA binding activity than the Control group ($P$ < 0.001). These results suggest that in the presence of high cholesterol, lutein exerts both antioxidant and anti-inflammatory effects, which can be explained by attenuated NF-${\kappa}B$ DNA binding activity. Furthermore, results also suggest that lutein accumulates in the eyes of guinea pigs to protect against oxidative stress.

This study is to delineate the watershed hydrological parameters such as area, slope, rain gauge weight, NRCS-CN and time of concentration (Tc) by using the Geographic Information Sytem (GIS) technique, and estimation of design flood for an ungauged watershed. Especially, we attempted to determine the Tc of ungauged watershed and develop simple program using the cell-based algorithm to calculates upstream or downstream flow time along a flow path for each cell. For a $19km^2$ watershed of tributary of Nakdong river (Seupmoon), the parameters including flow direction, flow accumulation, watershed boundary, stream network and Tc map were extracted from 30m Agreeburn DEM (Digital Elevation Model) and landcover map. And NRCS-CN was extracted from 30m landcover map and soil map. Design rainfall estimation for two rainfall gauge which are Sunsan and Jangcheon using FARD2006 that developed by National Institute for Disaster Prevention (NIDP). Using the parameters as input data of HEC-l model, the design flood was estimated by applying Clark unit hydrograph method. The results showed that the design flood of 50 year frequency of this study was $8m^3/sec$ less than that of the previous fundamental plan in 1994. The value difference came from the different application of watershed parameter, different rainfall distribution (Huff quartile vs. Mononobe) and critical durations. We could infer that the GIS-based parameter preparation is more reasonable than the previous hand-made extraction of watershed parameters.

Since the report in 1946 on the first isolation of Japanese encephalitis virus in Korea, the disease is known to occur every year and has occasionally spread in epidemic proportion among human populations. Because of its public health importance, it was deemed highly desirable to gain specific information as to natural history of the disease in Korea if we are to accomplish our ultimate objective of controling the disease in Korea. There still remain, however, unknown factors as to the ecology of Japanese encephalitis virus in Korea. This paper presents the results of serologic study on Korean cattle, hog and horse by means of hemagglutination inhibition (H.I.) test. The serum specimens were collected from Korean cattle, hog and horse their estimated ages being 3 to 9 years, 6 to 24 months and 2 to 14 years respectively, by jugular puncture; in Seoul and Kyung-Ki are a from the first part of May to November last, 1968. The strain used was designated by M 5/596. The methods of H.I. test employed in this study were essentially simillar to those employed by Clark and Fred. The results obtained summarized as follows; 1. Of samples of cattle sera tested, 183 (98%) was found to be positive, H.I. antibodies showing the highest proportion, on September. The lowest proportion showed 81 (68%) of 117 samples, on June. 2. One hundred and ninety-five and 114 swine serum samples tested were all of positive in both on September and October respectively. The lowest proportion showed 92 (29%) of 314 on June too. 3. Ninety (99%) of 91 equine serum samples tested contained demonstrable H.I. antibodies the highest proportion, on August. The lowest proportion was 19 (27%) of 70 samples on June. 4. Implications of these findings in the ecology of Japanese encephalitis Seoul and Kyung-Ki area were discussed.

Background: This study was performed to evaluate the amplification of HER-2/neu in patients with melanoma. Materials and Methods: Amplification of HER-2/neu was evaluated in a group of patients with melanoma, referred to two referral centers in Tehran, using immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH) techniques. Results: Forty patients with mean age $57.9{\pm}19.5years$ were enrolled in this study. The most frequent type of melanoma was acral, while lower limbs were the most frequent sites. The amplification of HER2/neu was negative in 97.5% of patients with IHC and in 100% of patients with CISH technique. Only one case (2.5%) shows weak positive staining (+2) in IHC method. Fifty five percent of melanoma was ulcerative, and the most common stages of tumors were stages 4b and 3b. More than 47% of cases were in Clark level III, while the mean of Breslow thickness was $3.56{\pm}2.87mm$. The stage of the case that showed weakly positive staining (2+) in IHC was 4b. Conclusions: The amplification of HER2/neu biomarker was negative in patients with melanoma, using both CISH and IHC techniques.

Background: Colorectal cancer (CRC) is a leading cause of cancer death among Vietnamese Americans, yet screening remains underutilized. We investigated the effectiveness of a culturally tailored DVD intervention in promoting CRC screening among unscreened Vietnamese Americans age 50 and over. Materials and Methods: Using a community-based participatory research approach, we conducted a trial comparing twenty-eight subjects who received a mailed DVD in Vietnamese, with twenty-eight subjects who received a mailed brochure in Vietnamese. Subjects completed telephone surveys at baseline, One-month, and one-year. The primary outcome was receipt of screening. Secondary measures were participants' knowledge, attitudes, and beliefs about CRC screening. Two focus groups explored the intervention's acceptability and effectiveness. Results: At one year, CRC screening rates of 57.1% and 42.9% were observed in experimental and control group respectively (p=0.42), Subjects in both groups showed increased knowledge about CRC after one month. Focus group findings revealed that the DVD was an effective method of communicating information and would help promote screening. Conclusions: The findings suggest that culturally tailored, linguistically appropriate content is more important than the type of media used. This relatively low intensity, low cost intervention utilizing a DVD can be another useful method for outreach to the often hard-to-reach unscreened population.

This study was a cross-sectional survey of the effects of pregnancy necessity recognition on emotional happiness and mediation effect of health control behavior on it. A total of 200 participants in the study were collected from structured questionnaire online and the data collection was from July $1^{st}$ to July $31^{st}$, 2018. Health control behavior questionnaire was developed by Wallston, K.A., Wallston, B.S. & Devellis, R (1978), Emotional happiness was analyzed by using PANAS (positive and negative affect schedule) developed by Watson, Clark and Tellegen (1988). The collected data were chai-square($X^2$), Pearson correlation, Dummy regression analysis, simple regression analysis, and the mediated effect analysis by SPSS 18.0. As a result, Under statistical significance, there were differences in the recognition of pregnancy necessity were depending on religion, participant's age, number of siblings, thought of optimal marriage age(p<0.05). More siblings, more religious, older age, and more recognized the pregnancy necessity. The analysis of Pearson correlation with the pregnancy necessity, health control behavior, and emotional happiness reveled that it was relevant (p<0.01). Dummy regression analysis showed that people who thought that pregnancy was necessary were 0.700 times more likely to felt emotional happiness that people who thought it was unnecessary (p<0.01). Analysis on the mediation of health control behavior, in which the effects of pregnancy recognition on emotional happiness, showed that it was effect (other people's health control behavior: B:.299, p<0.01, internal health control behavior : B:.217, p<0.05). Based on these results, this study suggested that to promote pregnancy recognition, families with brother and sister should be programmed with recommendations for exercise and alcohol abstinence, religious belief and health control programs.

The objective of this study is to clarify the early state of modern architecture, specifically mission architecture, with the introduction of the Christianity, and for the goal it deals with the architectural activities of pioneer missionaries. Especially it is a piece in a series of those researches after on Graham Lee, and it is focused on the other representative missionary, R. M. Wilson, A. M. Sharrocks, and C. A. Clark. Although coming in the capacity of a medical doctor or an educator, they should play all kinds of roles, such as carpenters, educators, and officers. For this mission, even they didn't have a professional knowledge for construction, they should carried on to establish mission compounds, only with their experience and informations. In this process they needed to be assisted by Korean carpenters, surely. The architectures born by them-selves are designed with a unique eclectic style compounded with those of Korean traditional and occidental. That is to say, the pioneer missionaries made a profound influence to create a new tradition of modern architecture in Korea, which is called as Korean-occidental eclectic style in the period of transition. Moreover, some pioneer missionary, such as Sharrocks, took a part in education of architectural skills. The educated carpenters seemed to be called from outside, and the unique styles could get spread away. On this point this paper has the meaning to clarify historically the continuous development of the Korean architecture through the survey on their activities, on the contrary of the existed recognition that Korean modern architecture has been evaluated to be imported from outside; therefore having a crevice with the its own architectural tradition.

본 논문의 목적은 우리나라 도시공간구조 변화를 시계열적으로 분석하고, 지역별 규모별 그 특성을 도출하는 것이다. 본 논문에서 도시공간구조는 인구밀도경사함수(population gradient curve)를 통해 분석하였고, 분석의 시간적 범위는 자료구축의 가능성을 고려하여 2000년부터 2010년까지로 설정하였으며, 공간적 범위는 광역시를 제외한 70개 도시이다. 본 논문의 분석결과를 요약하면 다음과 같다. 첫째, 우리나라 도시들은 평균적으로 도심 인구밀도는 감소하고, 인구밀도 경사도는 완만해져 도심 집중현상보다 외곽지역으로의 확산이 활발하게 진행되는 것으로 나타났다. 둘째, 비수도권 지역은 전국 평균과 동일한 형태의 공간구조 변화를 경험하였지만, 수도권 지역은 외곽지역뿐만 아니라 도심까지 인구밀도가 함께 높아지는 현상이 나타났다. 셋째, 인구 20만 이상의 중도시와 대도시에서는 도심 집중현상보다는 도시 외곽지역으로의 확산이 우세하게 나타난 반면, 인구 20만 미만의 소도시에서는 도심 인구밀도가 높아지면서 인구밀도 경사도의 절댓값이 커지는 도심 집중현상, 즉 압축도시의 특성이 나타나는 것으로 분석되었다.

본 연구는 은행 자동화기기(CD/ATM기)의 공간적 분포와 입지요인 분석을 통해 금융정보화 시대의 역동적인 공간 변화의 한 면모를 밝히고자 하였다. 자동화기기의 공간적 분포는 은행 점포와 비슷한 양상을 보였으므로. 입지계수 분석을 통해 두 분포의 상대적 차이를 밝혔다. 또한, 본 연구에서는 자동화기기의 입지에 중요한 영향을 끼치는 네 가지 요인을 규명하였다. 은행 점포의 입지에는 자동화기기에 비해 지역 경제기반 및 지역경제력 요인의 영향이 상대적으로 중요한데 반해. 자동화기기의 입지에는 인구나 수요유발 요인의 영향이 상대적으로 크게 작용하였다. 이러한 차이는 자동화기기와 은행 점포에서 제공되는 서비스가 차별적이라는 데 기인한다. 한편, 지역별로 점포와 자동화기기의 상대적 분포 차이를 가져오는 데 가장 큰 영향을 미치는 요인은 수요유발 요인으로 나타났다. 이는 점포에 비해 자동화기기의 설치 및 운영비용이 현저히 낮아 현금 수요가 빈번한 곳에 유동적으로 설치될 수 있기 때문이다.
