본 연구의 목적은 간호대학생들의 아르바이트 실태를 파악하고, 아르바이트 경험의 다양한 요인들 중 간호사에게 필요한 의사소통능력, 자기 효능감, 사회적 기술에 미치는 효과와 요인과의 상관관계를 파악하고자 하였다. 본 연구의 대상은 S, B, G시 소재의 간호대학에 재학 중인 대학생 362명을 참여자로 선정하였다. 자료분석방법으로 대상자의 아르바이트 경험유무와 일반적 특성과의 관계는 Chi-square(${\chi}^2$) test, Fisher's exact test검정으로, 일반적 특성에 따른 의사소통능력, 자기 효능감, 사회적 기술척도의 집단 간의 차이는 t-test, Analys of variance(ANOVA)검정으로 분석하였다. 연구에서 나타난 결과는 간호대학생의 91.7%가 아르바이트를 경험하였으며, 8.3%는 아르바이트를 경험하지 않았다. 아르바이트 경험유무와 일반적 특성과의 관련성에서 경제적 수준이 낮을수록 아르바이트를 경험하는 것으로 나타났다. 아르바이트를 하게 된 요인으로는 '용돈 마련'이 77.9%로 가장 높았으며, 아르바이트 분류항목에서 '카운터 및 서빙' 부분이 62.2%로 가장 많았다. 아르바이트 경험에 따른 간호대학생의 의사소통능력, 자기 효능감, 사회적 기술의 정도와 관련하여 아르바이트 시작시기와 통계적으로 유의한 차이가 있는 것으로 나타났다. 특히 중학교 시기에 아르바이트를 경험한 학생들의 의사소통능력, 사회적 기술 능력이 고등학교 시기 이후에 아르바이트를 경험한 학생들에 비해 낮은 점수를 보여주었다. 본 연구결과를 토대로 간호대학생의 아르바이트 경험에 대한 강점을 파악하고 이를 적용할 수 있도록 하는 지속적인 연구가 요구된다.

This study is to review the costumes of female Shamans through Gamrotaenghwa(甘露幀畵) in the late Joseon Dynasty of the 18th and 19th centuries. The picture of Mudangnaeryeok(巫堂來歷) showing Shamanic performances which is kept in Kyujanggak, Seoul National University was the only one thing enabling to compare with the Shamanic costumes shown in Gamrotaenghwa. The earlier Gamrotaenghwa doesn't show the Shamanic features but that of the later part of 18th century shows specific costumes so that the scene of Shamanic performance can be guessed. The Shamanic costumes are classified into 5 types. Type A is considered to have followed the figures shown commonly in earlier Gamrotaenghwa of the 16th and 17th centuries, rather than the traditional costumes. Types B through E show the costumes of the Joseon dynasty. With the basic costumes of skirt and Chogori(a kind of jacket, Type B), the variable costumes worn for each type of Shamanic performances are Mongduri(蒙頭里, Type C), Jeonbok(戰服, Type D) and Cheolrik(天翼, Type E). Reviewing the general style of those costumes, the upper part was tight and the lower part was silhouette of big volume, and the length of Chogori was a little long in the early of 18th century but it became shorter with narrower sleeves from the later part of the same century. According to the general literatures about the outer collars were not overlapped and its side parts were open, with half or no sleeves. In case that the target of Shamanic performance is male god, the Shaman wore the male costumes represented by Cheolrik and Jeonbok. Because these Cheolrik and Jeonbok which were worn during the Shamanic performance have the symbolic meaning to correspond with the male god, they didn't function as ordinary costumes.

Two-phase flow through a T-junction has been studied by numerous researchers so far. The dividing characteristics of the gas and liquid phases at the T-junction are very complicated due to a lot of related variables. The prediction models have been suggested by using experimental data for a specific condition or working fluid. But, they showed the application limitation for the most of the other conditions or fluids. Since most of them are applicable for their own experimental range, the generalized model for the wide range of conditions and fluids is needed. Even though it's not available now, some of the models developed for air-water flow at a T-junction might be applicable for the part of refrigerants with some modifications. Especially, for the two-phase flow of refrigerants at the T-junction, very few studies have been performed. Further experimental study is required to be performed for the wide range of test conditions and fluids to predict properly the two-phase flow distribution and phase separation through the T-junction.

ITU(International Telecommunication Union)를 비롯한 IMTC 등의 국제 표준기구에서는 멀티미디어 회의서비스를 제공하기 위하여 필요한 여러 가지 응용들과 프로토콜 등에 대하여 ITU-T T.120 시리즈로 표준화 작업을 진행하고 있다[1-10]. 그 중 원격 기기 제어는 멀티미디어 회의에 다음의 능력을 제공한다. 첫째, 회의 참가자가 회의 내 기기 및 기기가 제공하는 속성들을 파악할 수 있게 해준다. 둘째, 회의 참가자가 기기를 배타적 및 비 배타적으로 제어할 수 있게 해준다. 셋째, 회의 참가자가 기기의 상태를 파악하고, 사건통지를 받을 수 있게 해준다. 넷째, 회의 참가자가 외부 기기를 선택하여 그 정보를 받을 수 있게 해준다. 본 논문에서는 멀티미디어 회의에서 원격 기기 제어를 수행하기 위하여 사용되는 RDC(Remote Device Control) 및 구현된 시스템을 소개한다. RDC 프로토콜은 현재 T.136[1]으로 표준화되고 있으며 T.120 모델에서 응용 프로그램 실체[2]로 등록하여 운용되고 있다. 소개되는 시스템은 T.136을 근거로 하여 구현되었으며, 다수의 기능을 추가하여 그 기능을 개선하였다.

This paper proposes a variable sampling interval multivariate $T^2$ control chart with sampling at fixed times, where samples are taken at specified equally spaced fixed time points and additional samples are allowed between these fixed times when indicated by the preceding $T^2$ statistics. At fixed sampling points, the $T^2$ statistics are composed of all quality characteristics and a part of quality characteristics are selected to obtain $T^2$ statistics at additional sampling points. A Markov chain approach is used to evaluate the performance of the proposed chart. Numerical studies for the performance of the proposed chart show that the proposed chart reduces the observations obtained from a process and detects the assignable cause of a process with low correlated quality characteristics quickly.

Let { $A_{>o}$ t= exp(M log t)} $_{t}$ be a dilation group where M is a real n$\times$n matrix whose eigenvalues has strictly positive real part, and let $\rho$be an $A_{t}$ -homogeneous distance function defined on ( $R^{n}$ ).

For f$\in$ $L_{1}$ ( $R^{n}$ ), define f(x)=sup t>0 Kt*f(x)=t-v K(Al/tx) and v is the trace of M. Then we show that \ulcorner is a bounded operator of $L_{-{1}( $R^{n}$ ) into $L^1$,$\infty$( $R^{n}$).

Accurate flow rate distribution has been become a very important part for controling of air change rate since the introduction of house ventilation system. An inappropriate selection of fan due to Incorrect prediction of friction loss makes waste energy. The purpose of this study is to recognize applicability of T-Method at house ventilation system by comparing experiment with T-method, The result of this study is as follows Flow rate is small amount in a house, so duct size must be accurate. And duct design with Equal Friction Loss Method presented large error range. Equal friction loss method is not fit to applicate small amount air flow rate. T-Method predicts accurate flow rate comparatively in a house ventilation system. Error range was 3.5%.

To make the research and development in IoT networks witness a significant improvement and last for a long period, it is always important to attract new researchers to work on this area and be a part of it. The best way to attract researchers to work in any research area and have their interest is to give them a clear background and roadmap about it. In this way, researchers can easily find a deep point to start their research based on their interest. This paper presents an overview and roadmap about IoT technologies from the most five vital aspects: IoT architecture, communication technologies, type of IoT applications, IoT applications protocols and IoT challenges.

Cancer immunotherapies continue to face numerous obstacles in the successful treatment of solid malignancies. While immunotherapy has emerged as an extremely effective treatment option for hematologic malignancies, it is largely ineffective against solid tumors due in part to metabolic challenges present in the tumor microenvironment (TME). Tumor-infiltrating CD8⁺ T cells face fierce competition with cancer cells for limited nutrients. The strong metabolic suppression in the TME often leads to impaired T-cell recruitment to the tumor site and hyporesponsive effector functions via T-cell exhaustion. Growing evidence suggests that mitochondria play a key role in CD8⁺ T-cell activation, migration, effector functions, and persistence in tumors. Therefore, targeting the mitochondrial metabolism of adoptively transferred T cells has the potential to greatly improve the effectiveness of cancer immunotherapies in treating solid malignancies.
