To determine the contents of sodium (Na) and potassium (K) for restaurant dishes, 194 cases classified 26 kinds of restaurant dishes were collected from restaurants in Seoul and were analysed using the atomic absorption spectroscopy. Average contents of Na and K in Kimchi among restaurant dishes were highest as $554.9{\pm}155.5mg/100g$, $225.1{\pm}69.1mg/100g$, while average contents of Na and K were lowest in Seolleongtang as $24.2{\pm}5.8mg/100g$, $12.7{\pm}3.9mg/100g$ respectively. The contents between Na and K in restaurant dishes had a strong correlation of positive linear judging from 0.782 (p-value < 0.01) of the correlation coefficient. The Na/K ratio of Bulgogi was appropriate as $1.17{\pm}0.44$, while those of Udon, banquet noodles, Kalguksu were very high as shown more than 10. The contents of Na and K were examined 5 dish groups as Gook/Tang, Jjigae/Jeongol, stir-fried dish, noodle and Kimchi. Average contents of Na and K classified by dish groups were significantly difference (p-value < 0.001). Average content of Na among dish groups was highest in Kimchi as $554.9{\pm}155.5mg/100g$ followed by Jjigae/Jeongol, Gook/Tang, stir-fried dish and noodle. Similar to Na content, average content of K was highest in Kimchi as $225.1{\pm}69.1mg/100g$ followed by stir-fried dish, Jjigae/Jeongol, Gook/Tang and noodle. The ratio of Na/K by classified groups of dishes was shown as significantly difference (p-value < 0.001). Stir-fried dish was $1.18{\pm}0.44$ close to 1 followed by Kimchi, Jjigae/Jeongol, Gook/Tang, and noodle.

This study was carried out to investigate the quality characteristics of bread containing Houttuynia cordata Thunb. powder (HTP; in ratios of 0, 0.3, 0.5 and 1.0% of the total flour). We found that addition of HTP decreased the pH of dough, whereas the pH of bread remained unchanged. HTP caused no significant change in dough volume during fermentation. Baking loss did not show significant difference between HTP containing bread and control. However, we found changes in bread volume with the most pronounced decrease observed in bread containing 0.1% HTP. Lightness and redness of the inner crumb were decreased by the addition of HTP, whereas yellowness was increased. 2,2-diphenyl-1-picrylhydrazyl-radical scavenging activity and total polyphenol contents were increased significantly by the addition of HTP. The overall acceptability of bread containing 0.5% HTP was better than that of control.

근래 한국에서도 대표적 공공공간인 공원의 조성 및 관리와 관련하여 파트너십에 대한 관심이 일고 있다. 주민들이 만들어가는 공원, 다양한 힘의 역학구조 속에서 공공성 유지, 지속 가능한 사회 구현에 도움이 될 것이라는 전망 때문이다. 이에 본 연구에서는 추후 한국에서의 실천과 제도정비에 도움이 될 수 있도록, 영국에서는 어떻게 정책적으로 파트너쉽을 유도하는지 그리고 커뮤니티는 이를 어떻게 수용하여 자신들의 사례를 만들어 가는가를 살펴보았다. 사례연구에 있어서는 질적 연구방법을 택했으며, 분석보다는 사례가 갖는 내러티브(narratives)를 다층적으로 서술하는데 초점을 두었다. 이것은 거대 내러티브가 사라지고 있는 현대 사회에서 일반적 원칙보다는 개별 사례의 구체성을 밝히는 것이 보다 중요하다는 일부 사회학 연구자들의 견해를 수용한 것이다. 더욱이, 주민참여 관련 사례는 지역특성과 주민의 영향을 많이 받기 때문에 이러한 연구방법이 유용할 것이다. 더불어, 이러한 방식은 자못 추상적 이해에 그칠 외국 사례를 보다 구체적으로 이해하는데 적합할 것이다. 연구결과에 있어, 먼저 영국에서는 지방의제21(LA21)이 지방정부의 서비스에 대한 근본적 태도와 체계를 바꾸는데 기여했다는 것을 알 수 있었다. 일례로, 뉴캐슬(Newcastle upon Tyne)시는 직접 서비스를 제공하기 보다는 주민들의 참여를 촉진하고 도와주는 방향으로 역할을 전환하고 있었다. 그리고 다양한 자금지원체계는 직접적으로 파트너십을 독려하고 있었다. 영국 뉴캐슬(Newcastle upon Tyne) 웨이브리 파크(Waverley Park) 사례를 살펴본 바에 따르면, 파트너십에 대한 지방정부의 태도가 성공적 파트너십에 있어 중요한 요소임을 확인할 수 있었다. 이 사례에서는 프렌즈그룹 이외, 커뮤니티 외부의 비영리 단체가 참여하지 않았는데, 이는 지방정부가 적극적으로 주민들의 참여를 촉구하고 도왔기 때문이다. 이외, 커뮤니티의 구성원과 공무원들의 개인적 역할도 중요하다는 것을 알 수 있었다. 중앙정부는 단지 자금뿐만이 아니라 다양한 사례에서 축적한 정보를 커뮤니티에 지원하고 전 과정을 모니터링 하고 있었는데, 간접적 참여라고 할 수 있다. 앞에서 언급했듯이, 본 연구는 영국에서의 파트너십과 관련된 제도, 그리고 제도가 구체적 현실에서 작동되면서 나타나는 특수성을 살펴보는 데 주력했다. 그런데 사례 연구에서 발견한 특수성을 한국에서의 시사점으로 명시하는 것은 한계가 있을 수 있다. 그래서 시사점은, 제도적 차원에서 한국과 영국을 비교하여 간략하게 제시했다. 첫째, 지방의제 21의 수용 방식이다. 한국의 지방정부 또한 지방의제 21을 실천하기 위해 협의회 등을 설치하였지만 행정 시스템을 전반적으로 변화시키고 있는 영국과는 차이점이 있다. 둘째, 공원과 녹지에 대한 지원금이 제공될 때, 지역주민의 동의를 요구하는 것은 커뮤니티의 참여를 독려하고 주인의식을 갖도록 하는데 효과적이라는 것도 시사점이 될 수 있다. 한국에서도 녹색복권 등 세원 이외의 자금이 공원 및 녹지 공간에 투입되고 있으나 주민들이 직접 이를 이용하도록 되어 있지는 않다. 즉, 커뮤니티의 참여와 관련되어 쓰이고 있지는 않다. 세 번째는, 커뮤니티와 공원과의 관계로 공원 설계와 관리에 있어서 영국에서는 커뮤니티가 직접 고객(client)으로서 역할을 하고 있었다. 한국에서도 계획 및 설계 과정에 주민을 참여시키는 경우가 있으나 의견청취 정도에 머물고 있고, 몇몇 시민단체를 중심으로 시민들이 직접 공원 관리에 참여하는 경우도 있으나 운동(movement)차원에 머물고 있을 뿐 이를 위한 제도적, 법적 토대가 구축되어 있지는 않다.

The effects of Zr/Ti concentration ratio in PLZT (10/y/z) thin films prepared by sol-gel method are investigated for the NVFRAM application. Rosette and pyrochlore phase are observed in PLZT (10/40/60) thin film and the (100) orientation, the grain size, and the surface roughness of PLZT thin films increase due to the increase of Ti amount in Zr/Ti concentration ratio. As Ti amount of Zr/Ti concentration ratio increases, the dielectric constants at 10KHz decrease from 600 to 400, while the loss tangents increase from 0.028 to 0.053 and the leakage current densities at 170 kY/cm decrease from 1.64$\times$10$^{-6}$ to 1.26$\times$10$^{-7}$ A/$\textrm{cm}^2$. In the results of hysteresis loops measured at $\pm$ 170 ㎸/cm, the remanent polarization and the coercive field increase from 6.62 to 12.86 $\mu$C/$\textrm{cm}^2$ and from 32.15 to 56.45 ㎸/cm, respectively, according to the change from 40/60 to 0/100 in Zr/Ti concentration ratio. Fatigue and retention properties also improve much as the Zr/Ti concentration ratio change from 40/60 to 0/100. After applying 10$^{9}$ square pulses with $\pm$5V, the remanent polarization of the PLZT (10/40/60) thin film decreases 50％ from the initial state while that of the PLZT (10/0/100) thin film decreases 30％. In the results of retention measurements of 10$^{5}$ s, the remanent polarization of the PLZT (10/0/100) thin film decreases only 11％ from the initial state, while that of the PLZT (10/40/60) thin film decreases 40%.

Trend surface analysis (TSA) was selected to estimate a natural trend in precipitation and to examine urban influences on precipitation over five urban areas (Houston, Dallas, and San Antonio, TX; New Orleans, LA; and Memphis, TN) in the southern United States. TSA was applied to monthly, seasonal and annual normal precipitation data for the period of 1961-1990. Winter and spring have more trends than summer and fall and the period of November through March have more marked trends than the period of April through October in all study areas except the Houston area. Residual maps for Houston, Dallas and San Antonio have positive residuals in the city and downwind during summer indicating that urban effects on precipitation enhancement in these areas do exist during these seasons after eliminating the natural precipitation variations. Summer residual maps for New Orleans and Memphis have no distinct precipitation increases due to urban effects. The June residual map in New Orleans and the July residual map in Memphis have positive values in the city, but the magnitude of values is smaller than other cities.

This study aimed to compare the differences in sexual function and sexual preference according to demographic characteristics of women, sexual experience, preference penile type, and sexual dysfunction. 72 adult women responded to the survey. 54 respondents were analyzed except respondents who did have incomplete response and no sexual experience. All collected data were analyzed using independent t-test and chi-square test using SPSS 22. In results, Married was significantly higher in intercourse frequency and sexual function than unmarried(p<.05). In economic status, high or middle was significantly higher in the subjective sexual experience and sexual function than the low(p<.05). In subjective sexual experience, high was higher in intercourse frequency than the low, and penile length and type were important(p<.05). preference of glans> penis was significantly higher in subjective sexual experience than preference of glans $${\frac{._-}{.}}$$ penis, and importance of penile girth and size(p<.05). In sexual function, normal function was lower in intercourse frequency than dysfunction, and penile length was not considered significant(p<.05). The results of this study suggest that there may be differences in sexual function and sexual preference according to various causes and can be used as basic data for the development of psychological counseling program for sexual function rehabilitation of women.

Modern disasters prevent accidents in advance and recover after accidents are very important. Our government's current response to these accidents is not appropriate. As for disaster management so far, it has been the center of disaster response and recovery efforts, and has been led by the government against it. The reality is that most private organizations and agencies have only subsidized government disaster management agencies. Korea is no longer a safe zone for earthquakes. Now for the establishment of effective disaster management system for earthquakes in the diagnosis is very urgent and the problems of the operational disaster management, which the problems of the nation.Policies to improve academic efforts to seek alternative proposal is also at a time when volume can be said to be very big need to mine. This study from 2016 to 2019, about the earthquake that took place between National Statistical Office, based on analysis of data to. First of all, research 1: What was the government's plan on Pohang earthquake? The results showed that the residents' evacuation of Pohang was important in the Pohang earthquake, but for the sake of students' safety, they were directly assigned to the test site to cope with the emergency situation. Therefore, the research and analysis shows that the nation should continue to think about the causes and responses of the damage at the disaster site and strive to develop technologies and methods to minimize the damage.

RF 마그네트론 스퍼터링법을 이용하여 Ar과 $O_2$의 유량을 25sccm씩 흘리면서 $SiO_2$/Si기판 위에 Sn $O_2$ 박막을 증착하였다. 증착된 박막은 columnar 구조로 성장하였으며 많은 입자들이 뭉쳐서 형성된 양배추꽃(cauliflower) 형태의 뭉친 입자(agglomerates)를 가지는 표면형상이 관찰되었다. 분위기에 따른 어닐링 효과를 확인하기 위하여 50$0^{\circ}C$에서 공기와 질소 분위기하에서 열처리하였다. 열처리한 후 표면거칠기가 개선되었으며, 표면형상의 변화가 발생하였다. 특히 50$0^{\circ}C$, 질소분위기에서 어닐링한 경우는 양배추꽃 형태의 표면형상이 소수의 작은 입자가 뭉친 형태로 분리되면서 입도분포가 개선되었다. 이러한 결과는 어닐링 과정에서 발생되는 응력을 완화시키기 위하여 표면형상의 변화가 발생하는 것으로 판단된다. XPS 측정 결과, 질소 분위기에서 어닐링한 후에 OIs와 Sn5/3d 피크가 낮은 결합에너지에 위치하고 있어 산소공공의 농도가 어닐링 전에 비하여 증가하였음을 확인할 수 있다. 어닐링 전후에 Sn $O_2$ 박막의 면저항 측정 값은 XPS 결과와는 달리 질소 분위기 어닐링한 후에 오히려 면저항값이 크게 증가하였다. 이러한 결과는 질소 분위기 어닐링한 후 표면형상의 변화에 기인하여 입자간의 연결성이 저하되어 면저항값이 증가한 것으로 추정된다. 산소분위기에서 어닐링한 후에 전체적으로 전기적 특성의 재현성이 개선되었으며 Sensitivity( $R_{air}$/ $R_{gas}$)가 향상되었음을 확인하였다.하였다.석을 통하여 La의 분포를 확인하였으며, HRTEM 분석을 통하여 미세구조분석을 실시하였다.2463eV였다. 10K에서 광발광 봉우리의 919.8nm (1.3479eV)는 free exciton(Ex), 954.5nm (1.2989eV)는 donor-bound exciton 인 I2(DO,X)와 959.5nm (1.2921eV)는 acceptor-bound exciton 인 I1(AO,X) 이고, 964.6nm(1.2853eV)는 donor-acceptor pair(DAP) 발광, 1341.9nm (0.9239eV)는 self activated(SA)에 기인하는 광발광 봉우리로 고찰되었다.가 높을수록 방출전류가 시간에 따라 급격히 감소하였다. 각 duty비에서 방출전류의 양이 1/2로 감소하는 시점을 에미터의 수명으로 볼 때 duty비 대 에미터 수명관계를 구해 높은 duty비에서 전계방출을 시킴으로써 실제의 구동조건인 낮은 duty비에서의 수명을 단시간에 예측할 수 있었다. 단속적으로 일어난 것으로 생각된다.리 폐 관류는 정맥주입 방법에 비해 고농도의 cisplatin 투여로 인한 다른 장기에서의 농도 증가 없이 폐 조직에 약 50배 정도의 고농도 cisplatin을 투여할 수 있었으며, 또한 분리 폐 관류 시 cisplatin에 의한 직접적 폐 독성은 발견되지 않았다이 낮았으나 통계학적 의의는 없었다[10.0%(4/40) : 8.2%(20/244), p>0.05]. 결론: 비디오흉강경술에서 재발을 낮추기 위해 수술시 폐야 전체를 관찰하여 존재하는 폐기포를 놓치지 않는 것이 중요하며, 폐기포를 확인하지 못한 경우와 이차성 자연기흉에 대해서는 흉막유착술에 더 세심한 주의가 필요하다는 것을 확인하였다. 비디오흉강경수술은 통증이 적고, 입원기간이 짧고,

Studies of atmospheric general circulation in the troposphere and stratosphere are very important to understand the influence of human activities on the global climate and its change. Recently, the existence of an annual cycle in the circulation has been reported by a number of studies. In this study, the residual mean meridional circulation is calculated by the TEM momentum and continuity equations for the period from December 1985 to November 1995 (10 years), and the long-term variations of the circulation and mass fluxes across the 100hPa surface are examined. The multiple regression statistical model is used to obtain quantitatively the long-term variations. This study is focused especially on mean meridional circulation in the troposphere and stratosphere associated with ENSO (El Ni${\tilde{n}}$o-Southern Oscillation) which is known as a cause of the unusual weather, global climate, and its change. The results show that the global scale troposphere-stratosphere mean meridional circulation is intensified during El Ni${\tilde{n}}$o event and QBO (quasi-biennal oscillation) easterly phase and weakened during La Ni${\tilde{n}}$o event and QBO westerly phase. The signal of Mount Pinatubo volcanic eruption in June 1991 is obtained. Due to the volcanic eruption the global scale troposphere-stratosphere mean meridional circulation is abruptly intensified.

Jung, Sang Won, Sung-Sik Park, Yong-Cheol Park" Tae Kwang Oh2, and Jin-Ho Seo*, Department of Food Science and Technology, Seoul National University, Suwon 441-744, Korea, 1lnterdisciplinary program [or Biochemical Engineering & Biotechnology, Seoul National Univer5it}~ Seoul 151 "7421 Koreal 2Microbial Enzyme RU, Korea Research Institute of Bioscience & Biotechnology, Po. Box 1151 Yusong, Taejon 305"6001 Korea - This research was undertaken to analyze fermentation properties of Thermoactinomyces sp. E79 for production of a thermostable alkaline protease, which is able to specifically hydrolyze defatted soybean meal (DSM) to amino acids. TIle optimum pH for cell growth and protease production was pH 6.7, Thermoactinomyces sp. E79 did not grow at pHlO Among carbon sources tested, soluble starch was the best for protease production, while glucose repressed protease production. Tryptone was found to be the best nitrogen source for cell growth and soytone was good tor protease production. Oxygen transfer rate played an important role in producing thermostable alkaline protease. Ma'<..imum values of 6.58 glL of dry cell weight and 43.0 UJmL of protease activity were obtained in a batch fermentation using a 2.5 L jar fermentor at 1.93 X 102 hr-l of volumetric oxygen transfer coeff'jcient (kLa). Addition of 200 mgIL humic acid to the growth medium resulted in 1.64 times higher protease activity and 1.77 times higher cell growth than the case without humic acid addition.
