Background: In this paper, the relationship between the Cranio-Vertebral Angle (CVA) and the vital capacity in each position is reviewed, and the vital capacity in the position is studied. Methods: This study targeted 20 non-smoking female students of U university, which is located in Gyeongju-si. To review the Forward Head Posture (FHP) of each subject, CVA was measured, and FVC, FEV1, and FEF (25-75%) were measured and analyzed using a spirometer. Subjects were ordered to exhale three times with ease and then inhale up to their total lung capacity. After then, they were requested to exhale longer than six seconds. Then the inspiration and expiration were repeated. The measurement was executed in three positions, including supine, prone, and sitting. In each position the measurement was repeated twice, and a one-minute break was given between each cycle, so it was measured six times in total. SPSS 14.0 for Windows was used to analyze the data. The subjects' general properties were analyzed using descriptive statistics, and the correlation between the angle and the respiration variable result in each position was analyzed. The result of the respiration variable in each position was analyzed using the one-way ANOVA, and then a Scheffe post-hoc comparison was executed. Results: According to the analysis result of the correlation between the angle and respiration variable in each position, the sitting position and FEF (25-75%) showed a positive correlation (P<0.05). The respiration variable in each position showed a significant difference in FVC (p<0.05), and the Scheffe post-hoc comparison differed in prone and sitting positions. Conclusion: To increase the FVC of FHP patients, different exercises for each position can be applied, and the result of this study can be utilized as background data for further research.

We report the structural and electrical properties of hafnium oxide (HfO$_2$) films with tungsten silicide (WSi$_2$) metal gate. In this study, HfO$_2$thin films were fabricated by oxidation of sputtered Hf metal films on Si, and WSi$_2$was deposited directly on HfO$_2$by LPCVD. The hysteresis windows in C-V curves of the WSi$_2$HfO$_2$/Si MOS capacitors were negligible (<20 mV), and had no dependence on frequency from 10 kHz to 1 MHz and bias ramp rate from 10 mV to 1 V. In addition, leakage current was very low in the range of 10$^{-9}$ ~10$^{-10}$ A to ~ 1 V, which was due to the formation of interfacial hafnium silicate layer between HfO$_2$and Si. After PMA (post metallization annealing) of the WSi$_2$/HfO$_2$/Si MOS capacitors at 500 $^{\circ}C$ EOT (equivalent oxide thickness) was reduced from 26 to 22 $\AA$ and the leakage current was reduced by approximately one order as compared to that measured before annealing. These results indicate that the effect of fluorine diffusion is negligible and annealing minimizes the etching damage.

본 연구에서는 TBM터널의 설계 및 평가를 위한4가지 분석시스템을 소개하고 그 특징들과 입력자료들을 비교 분석하였다. 그 중 두가지 시스템은 수리 및 고장등에 사용된 시간과 설치 및 이동시간 등이 입력자료로 사용되므로 터널 완료후 평가할 수 있는 방법이며, 나머지 두가지 시스템은 초기 기본적인 암석 및 암반 조건 그리고 TBM 제원 등으로 계산이 가능하므로 TBM 터널설계시 예측이 가능한 방법이다. 그러나 이러한 방법의 적용을 위해서는 많은 수식, 그래프 그리고 도표 등의 사용이 요구되므로 TBM 터널 평가를 위한 분석시스템의 이용이 매우 불편하고 복잡하다. 본 연구에서는 터널 기술자들이 쉽게 사용할 수 있도록 사용자 친화적인 윈도우용 프로그램을 개발하였으며, 개발된 프로그램은 입력자료가 서로 일치하는 각각의 방법을 적용할 수 있는 장점이 있다. 개발된 프로그램을 이용하여 다양한 프로젝트 현장 조건 및 목적에 맞는 분석시스템의 선택과 용이한 적용이 가능할 것으로 기대된다.

An SHGC(Solar Heat Gain Coefficient) is a determinant of total flux of solar radiation coming indoor and a critical factor in evaluating heating and cooling load. U-value represents heat loss while SHGC denominates heat gain. Recently, windows with high solar gain, mid solar gain or low solar gain are being produced with the development of Low-E coating technology. This study evaluated changes in energy consumption for heating and cooling according to changes in SHGC when using double-layered Low-E glass and triple layered Low-E glass in relation to double layered clear glass as base glass. An Office was chosen for the evaluation. For deriving optical properties of each window, WINDOW 5 by LBNL, an U.S. based company. and the results were analyzed to evaluate performance of heat and cooling energy on anannual basis using ESP-r, an energy interpretation program. Compared to the energy consumption of the double layered clear glass, the double layered Low-E glass with high solar gain consumed $69.5kWh/m^2,yr$, 9% more than the double layered clear glass in cooling energy. The one with mid solar gain consumed $63.1kWh/m^2,yr$, 1% less than the base glass while the one with low solar gain consumed $57.6kWh/m^2,yr$, 10% less than the base glass. When it comes to tripled layered glass, the ones with high solar showed 2% of increase respectively while the one with mid solar gain and low solar gain resulted 5% and 11% in decrease in energy consumption due to low acquisition of solar radiation. With respect to cooling energy. it was found that the lower the SHGC. the less energy consumption becomes.

The purpose of this study is to explore factors influencing them and properties of exercise behaviors among rural elderly in Korea. To implementing it, data were gathered from a total of 356 elderly aged 65 and over living at the Seniors Well-being Villages being developed by the Rural Development Administration in Korea, using the structured questionnaires. also, data were analyzed by the SPSS / windows program. Results show that the exercise behavior of rural elderly was medium level as the average of 3.06 score($1{\sim}5$ score) and 44.2 percent among them didn't exercise regularly and 66.8% didn't participate in sports groups. Second, there were the difference in exercise behavior according to sex and age. Specifically, elderly men exercised more regularly and were aware of proper exercise methods than elderly women. However, there were no difference in exercise behavior according to age. Third, when we analyzed the difference in exercise behavior with the regularity of execution, the elderly who exercise regularly showed higher preference, awareness of necessity, regularity of execution, execution of stretching, participation in sports gatherings and awareness of proper methods than the counterparts. Fourth, we found that unhealthy elderly were more aware of necessity of exercise, exercised regularly, and participated in sports groups frequently than healthy elderly. Also, there was a positive influence of regularity of execution on exercise behavior. These results suggested that regular exercising is very important in health of rural elderly. Therefore, to improve their health, above all, exercise program must be developed

This study focuses on the regional characteristics observed in the composition and floor plan of folk houses in the Young-cheon region situated in the Southern East inland of Gyungsangbukdo. According to the typical characteristics of the Korean folk house, Young-cheon region is supposed to be classified as the Young-Nam region. Our study shows that the open inverse 'ㄱ' type composition is the most common among others, which consists the living room, UtChae and one BoosokChae that serves as a living room and a farm shop. The typical floor plan is called 'Young Nam type' 'H$\hat{o}$tjib' composed of four rooms. Young Nam type of house has a wall in front of the room floor with a door to make the space with the room floor as the internal space. This can be explained by the climatic conditions in the Southern region of Gyungsangbukdo, which has a very cold winter and has a harsh spring wind in Young-cheon. The structural feature to which we should pay attention is the Young Nam type house has a gambrel roof. The evolutions of the house in the 70s are observed in the roof during the Saemaeul Movement from a hut to a modernized roof. In the 80s, the replacement of the heating system, expansion of rooms, modernization of kitchen, replacement of paper windows, modernization of roof, and construction of amenities had taken place to change the space, construction and structure following the modern house features.
