기존의 NATM 터널에서는 숏크리트가 임시적인 지보재로 사용되었으나 싱글쉘에서는 영구적인 구조물의 역할을 담당하게 된다. 따라서 숏크리트에 작용하는 하중과 변위를 신뢰성 있게 예측하는 것이 터널의 안정성을 확보하기 위한 필수조건이므로 지반정수 산정의 정확성이 매우 중요하다. 특히, 국내의 지질상태는 외국과 다르므로 싱글쉘 공법을 국내에 적용하기 위해서는 국내 지질상태를 고려한 지반정수 산정기법의 기술 개발이 필수적이다. 본 연구에서는 국내 25개 터널 현장에서의 암반분류 사례 및 지반정수 사례를 조사하였다. 국내 싱글쉘 터널공법을 위한 지보 패턴안을, Q분류에서 수정된 NMT방법과 국내 암반상태를 고려하여 제안하였다. 또한 사례연구를 통한 Q시스템과 RMR값의 상관성을 이용하여 RMR을 이용한 지보량을 제시하였다.

이 연구는 질적 단일 사례연구로, 배우자 사별 경험이 있는 중년여성이 상호작용적 독서치료를 경험하면서 나타나는 변화를 탐색하기 위한 목적으로 수행되었다. 연구 참여자는 배우자 사별 외상 경험이 있는 40대 후반의 중년여성 1명이다. 본 연구에서는 상호작용적 독서치료 진행 중에는 회기 별로 참여자의 경험에서 나타나는 변화를, 상호작용적 독서치료 회기가 종결된 이후에는 참여자의 내적인 그리고 외적인 경험으로 구분하여 변화를 탐색하였다. 연구결과, 상호작용적 독서치료는 참여자의 자작시를 포함한 읽기 자료와 쓰기 기법이 참여자의 반응을 촉진하고 표출하는 역할을 하였다. 또한, 매체를 통하여 촉진된 감정과 자각된 인식은 상담자와의 치료적 상호작용을 통하여 현실에서의 자신을 이해하고 수용하게 하였다. 그리고 이러한 변화는 생활에서 내적, 외적 경험으로 나타났으며 회기 종결 이후에도 지속되었다. 여기에서 연구 참여자에게서 나타난 내적/외적 변화는 독서치료의 효과를 의미하고, 이는 텍스트와 더불어 상담자의 진실한 반응을 통하여 촉진된 결과임을 알 수 있었다.

As a way to use energy effectively, the present study is aimed at investigating the performance characteristics of a Single Effect LiBr/Water Absorption Refrigerator using a low temperature driving heat-source. It was carried out by changing the driving heat-source temperature, the cold water outlet temperature(the refrigeration load), the cooling water inlet temperature, and the weak solution flow rate and this study compares the performance characteristics of refrigerator against the existence and non-existence of the Recirculation of the Weak solution which is used as a method to improve the performance of refrigerator. In case of Recirculation of the weak solution, more improved the Refrigeration Capacity and COP was obtained, and these effects became more larger in the high temperature of driving heat-source and large quantity of solution.

In this study, the retractable-roof spatial structure was chosen as the analytical model and a tuned mass damper (TMD) was installed in the analytical model in order to control the seismic response. The analysis model is mainly consisted of runway trusses (RT) and transverse trusses (TT), and the displacement response was analyzed by installing TMD on those trusses. The mass of the single TMD which is installed in the analytical model was set to 1% of the total structure mass and the total TMD mass ratio was set to be 8% or 6%. In addition, the mass of a single TMD was varied depending on the number of installations. As a result of analyzing the optimal number of installations of TMD, the displacement response was reduced in all cases compared to the case without TMD. Above all, the case with 8 TMDs was the most effective in reducing he displacement response. However, in this case, as the load on the upper structure of the retractable-roof spatial structure increases, the total mass ratio of TMD was maintained and the number of TMDs was increased to reduce the mass ratio of one TMD.

Objective: This study was conducted to provide basic data for the establishment of effective health policies for the unmet medical experience that may occur among the elderly depending on whether they live in a singleperson household or not. Methodology: This study used data from the 8th National Health and Nutrition Examination Survey (2019-2020) and excluded cases with missing values in variables for the total number of respondent participants of 15,469. Finally, 2,850 subjects aged 65 or older were selected for final analysis. This study examined the relationship between experiences of unmet medical needs, attempting to confirm the relationship between single-person households and unmet medical needs through subgroup analysis considering gender, age, and household income. Results: According to the results, in the case of single-person households, the odds ratio (OR) for unmet medical needs was significantly higher at 1.60 times (95% CI: 1.16-2.21). Upon conducting subgroup analyses for gender, age, and household income quintiles, the OR was significantly higher at 2.24 times (95% CI: 1.14-4.41) for males and 1.48 times (95% CI: 1.02-2.14) for females, statistically significant in both cases. For individuals aged 65-69, the OR was significantly higher at 1.90 times (95% CI: 1.04-3.47), but for those aged 70-74 and over 75, it was not statistically significant. In the case of households with 'low' income, the OR was higher at 1.62 times (95% CI: 1.16-2.26), and for 'middle' income, it was significantly higher at 3.21 times (95% CI: 1.08-9.51). Conclusion: This study confirmed that the experience of unmet medical care is high among men who make up single-person households and low-income seniors. Therefore, this study suggests that policies to expand medical services and support welfare for single-person households should be established to resolve these problems, showing that health policies that take into account individual and regional characteristics are needed to improve medical accessibility for single-person households.

In the case of making large vocabulary speech recognition system, it is better to use the segment than the syllable or the word as the recognition unit. In this paper, we study on the basis of making biphone for Korean speech recognition. For experiments, we use the speech toolkit of OGI in U.S.A. The result shows that the recognition rate of the case in which the diphthong is established as a single unit is superior to that of the case in which the diphthong Is established as two units, i.e. a glide plus a vowel. And also, the recognition rate of the case in which the biphone is used as the recognition unit is better than that of the case in which the mono-phoneme is used.

Single household is expected to be the typical form of future Korean elderly household from reduction of household size and rapid growth of the elderly. As Japanese solve the same problem with Senior Sharehouse, a case study on Senior Sharehouse in japan focused on the Spatial Arrangement and Spatial Composition could suggest an potential applications in Korea. In conclusion, compare to Korea, the Senior Sharehouse in Japan supplies additional $7.5{\sim}9.3m^2$ more space to support the physical movement of the elderly and to help the elderly to solve various functions at one space. The independence and privacy of residents are also assured by supplying single occupancy. Space analysis shows that public space is as spacious (47.3~55%) as personal space. The result of the Space analysis suggests that the sharehouse provides rational ratio of space to assure residents' independence. It was supposed that the center type would be the main stream of the Spatial Arrangement for sharehouse considering its characteristic of sharing space. But, the Senior Sharehouse in Japan prefers corner type. The guarantee of personal space is being considered as a important characteristic. As a result of case analysis, Senior Sharehouse can be a proper type of house for single elderly household and present study can be used for the baseline data to solve the residence problem for single elderly household in Korea.

In case of favourable irradiation conditions, the ratio of irradiation to the total irradiation went up and then the irradiation increased in the area with high angle of inclination. The study showed that on a clear day with the irradiation of more than 80$[W/m^2]$, the pattern of alternating current power change in the fixed system was similar with that in the single-axis tracker. On the contrary, in case of unfavourable irradiation conditions, the ratio of diffuse irradiation to the total irradiation went up and then the horizontal irradiation increased. In the demo system, the fixed system, the single-axis tracker and the dual-axis tracker all had low generation power and similar generation pattern with each other. The study showed the generation power varied with the irradiation in the fixed system, while in the single-axis tracker and the dual-axis tracker, the amount of the generation Power variation was much more than the irradiation variation. The demo system was operated from 11:00 AM to 2:00 PM for generating power, during which time, 46[%] to 56[%] of the total generation power was produced. In this study, the generation power was increased by 147[%] in the fixed system, by 136[%] in the single-axis tracker, and by 164[%] in the dual-axis tracker, and the pattern of generation power was similar with the generation power variation in the situation where the irradiation increased by 140[%] in the spring with plenty of insolation. The alternating current power was more sensitive to variation of the irradiation than to that of the surface temperature of a module. The variation of the irradiation had a more positive effect on the generation power than the type of array.
