오늘날 병원마케팅에서 간호서비스는 병원 내 어느 전문직보다도 가장 많은 시간을 고객인 환자와 합께 나누며 환자의 욕구 충족을 위하여 고도의 분업화된 제반 부서들간의 활동을 조정하고 융화시키는 역할올 통하여 환자들이 지각하는 병원서비스의 만족도에 종요 한 부분을 차지하고 있으므로 병원마케팅의 전략적 초점으로 전환될 필요가 있다. 의료 서비스는 특성상 전문성이 강해서 정보가 소비자에게 공유되지 못하고 있으며 비영리조직이라는 인식하에 의료 서비스에 대한 광고를 제한합으로써 실제적으로 소비자에게 필요한 의료 관련 정보들마저도 제한을 받는 경우가 많이 있다. 그리고 의료서비스의 무형성, 비분리성, 이질성, 소멸성의 특성으로 어떠한 의료 서비스를 이용할 것인지해 대한 결정을 고객이 하기 어렵기 때문에 오늘날 의료 소비자들이 의료제공 기관을 선택 할 때는 밑올만한 다른 사랑의 추천에 크게 의존하고 있는 것으로 알려져 있으며, 국내의 연구에서도 의료소비자들이 병원을 선택하는 주된 정보 획득 원천이 주변의 제 3자인 것으로 알려져 있다. 이러한 정보 전달에 구전 커뮤니케이션이 주요한 제3자적 억할을 한다. 이러 한 관접에서 불 때 의료 소비자둘 사이의 구전 커뮤니케이션은 마케 팅 전략상 매우 종요하 며 마케팅 관리측면에서 의료 소비자들의 구전 커뮤니케이션 형태톨 파악하는 것은 매우 중요한 일이라고 할 수 있다. 이에 본 연구는 구전 커뮤니케이션의 내용 및 경로 그리고 유형을 파악하고 이들 유형간 의료서비스의 만족도를 알아봄으로써 효파적인 병원 마케팅 전략을 수립하는데 필요한 자료를 제공하고자 한다. 본 연구의 결과를 증합해 보면 의료소비자들이 연령 성별 학력, 소득, 직업, 주거지가 비슷한 사람과 구전이 활발하게 일어냐는 것을 파악 할 수 있어 특히 상업적 광고가 제한 된 병원의 마케팅 전략에 oH우 유용한 것이 훨 수 있다. 또한 불만족한 소비자일수록 발신 자적 입장에 서서 주위의 사람들에게 활발한 구전 활동을 수행하고 었음을 알 수 있다. 이 는 의료 소비자들이 만족한 경우보다는 불만족한 경우에 더욱 구전을 수행하려는 의지가 강해짐올 시사한다. 따라서 병원은 소비자들의 불만을 감소시키기 위해 노력해야 한다. 특히 의료인의 친절함이 가장 많이 구전이 되는 것을 알 수 있었는데 의사나 간호사는 치료 나 간호의 직접적인 제공자로서 의료 소비자들의 만족도에 중요한 영향을 미치므로 의료소 비자들의 요구에 부응하는 서비스를 충족시켜 줄 수 있도록 노력해야하며 이러한 바탕 위에 병원마케팅 전략이 수립되어야 할 것이다.

Objectives : The aim of this study was to analyze the relationship between depressive symptoms and sociodemographic factors associated with geriatric depression and insomnia and to examine the effects of these factors on depression. Methods : The severities of insomnia and depression in elderly aged 60 and older lived in Gwangmyeong city were evaluated and the related sociodemographic factors were investigated. From April 20, 2016 to December 1, 2016, Gwangmyeong city Mental Health Sevices consignment by department of psychiatry of a university-affiliated general hospital conducted surveys and interviews for total 837 elderly peoples lived in Gwangmyeong city by visiting welfare center and wards located in the city. Structured interviews were conducted using Insomnia Severity Index(ISI) and Short form-Geriatric Depression Scale(S-GDS) to examine the relationship between sociodemographic factors and the severities of insomnia and depression. Results : There were significant differences in S-GDS mean scores and age(below 70 years old, 70s, 80s, above 90 years old), type of health care(health insurance, medical aid), type of residency(own, not own) and marital status(single, married, divorced or widowed).There was a significant difference in education level, especially between not educated(and/or) elementary graduates and college graduate(F=3.227, p=0.012). Also, there were significant differences in age, type of health care, type of residency, number of household on divided S-GDS score above and below 10 scores(p<0.05). Insomnia measured by ISI was not significantly associated with sociodemographic factors(p>0.05), but was significantly associated with depressive symptoms(p<0.05). These findings suggest more severe insomnia symptom indicated the higher probability of depression and elderly with depressive symptoms had more severe insomnia. Conclusions : Geriatric depression has significant relationships with age, type of health care, type of residency, marital status, education and number of households. In addition, insomnia which is main symptom of depression in elderly, has important role in predicting the severity and diagnosis of depression.

Recently, It is increasing popularity to research on the soil remediation in aspect of management by reason of the hazardous impact on the contaminated soil in Korea. It was investigated high levels of arsenic salts in soil near abandoned five mines(Darak, Daduk, Jingok, Dalsung, Ilkwang) located in Youngnam area. Arsenic, classified as group A(Human Carcinogens) from IRIS, have shown statistically significant increment in skin cancer with oral exposure. This paper was conducted to predict excess cancer risk value (to the skin cancer) based on multiple pathway such as soil ingestion, dermal uptake and food(plant) ingestion contaminated by arsenic, and also, to identify the remedial goal regarded in future land use. The mine having the highest arsenic level was Daduk(mean : 1950mg/kg) and the next rank was Jingok(1690mg/kg), Ilkwang(352.37mg/kg), Dalsung(86.08mg/kg), Darak(0.83mg/kg). The chronic daily intake to the multiple exposure were calculated using Monte-Carlo simulation regarded in future land use and used q: value was $1.5(mg/kg/day)^{-1}$ to the oral proposed by IRIS(1997). The computated excess cancer risk 95th value to all the mine regarding future land use as residential and rural area were more than $10^{-4}$. If the level of acceptable risk is aimed for 1$\times$$10^{-6}$, it could be used Darak as commercial and industrial area without soil remediation due to the lowest risk value(6$\times$$10^{-8}$ and 3$\times$$10^{-8}$). Computated remedial goal based on 1$\times$$10^{-6}$ of acceptable risk to the future land use as the residential, rural, commercial and industrial area were 0.02mg/kg, 0.003mg/kg, 97.31mg/kg and 194.62mg/kg, respectively.

An investigation was conducted on the activities around Europe in order to solve the problem of the thermal bridging of steel studs, which had caused a significant disadvantage. This study included the following: diminishing the contact area between the studs and the sheathing, lengthening the heat transfer route, replacing the steel web with a less conductive material, and placing foam insulation in locations where the thermal shorts are most critical. Although energy efficiency is usually the focus of such foreign cases because their stud application is mostly limited to low-rise residential buildings, both structural and thermal performance are taken into consideration in this study because these target middle-story buildings. A hybrid stud composed of steel and polymer was also developed. This hybrid stud, which is 150 SL in size, is made of a galvanized steel sheet (SGC58) and a glass fiber reinforced polymer (GFRP) withepoxy bonding. A total of 32 specimens were manufactured. Its parameters comprise two types of connection detail,s: the thickness of steel (1.0mm and 1.2mm) and of the GFRP (4mm-4ply and 6mm-6ply), and the ratio of the length to the depth (L/D = 3, 6, 9, 12). Steel stud specimens with the same conditions were compared to the hybrid stud. The test revealed that in the case of the steel specimen with a thickness of 1.0mm, the maximum load of hybrid studs increased an average of 1.62 times comparedto that of the steel stud. In the case of the steel specimen with a thickness of 1.2mm, on the other hand, the average increase was 1.46times. All specimens showed full composite action until the collapse.

IEEE802.15.4a, which is started to realize the PHY layer including high precision ranging/positioning and low data rate communication functions, requires a simple and low power consumable transceiver architecture. To satisfy this requirements, the simple noncoherent on-off keying (OOK) UWB transceiver with the parallel energy window banks (PEWB) giving high precision signal processing interface is proposed. The flexibility of the proposed system in multipath fading channel environments is acquired with the pulse and bit repetition method. To analyze the bit error rate (BER) performance of this proposed system, a noise model in receiver is derived with commonly used random variable distribution, chi-square. BER of $10^{-5}$ under the line-of-sight (LOS) residential channel is achieved with the integration time of 32 ns and signal to noise ratio (SNR) of 15.3 dB. For the non-line-of-sight (NLOS) outdoor channel, the integration time of 72 ns and SNR of 16.2 dB are needed. The integrated energy to total received energy (IRR) for the best BER performance is about $86\%$.

While universities are making every effort to improve the housing welfare of university students by establishing new dormitories, the construction of school dormitories has intensified the conflict with other certified real estate businesses on the basis of their right to survival. Thus, it is necessary to analyze the causality in the conflict to coherently understand the conflict between these stakeholders. To do so, this study conducted a survey questionnaire on certified real estate businesses in the vicinity of private universities with dormitories in the metropolitan area. This study targeted licensed real estate brokerage agencies that conclude rental contracts in view of different stances, and control the real estate rental market by controling their conflict. Investigated the influence relationship between universities and licensed real estate brokerage agencies in relation to construction of private university dormitories and the effect of this conflict on management performance of licensed real estate brokerage agencies, and analyzed the relationship among relevant variables to see if their dormitory recognitions have a moderating effect. In addition to analyzing the causality of conflict level (perceived conflict, expressed conflict), conflict management, conflict outcome, and management performance, the study also verified the moderating effect of perception on dormitory and the mediating effect of conflict management. The results showed that conflict level had a negative (-) effect on conflict management, while the perceived conflict and conflict management of the conflict level had a negative (-) effect on the conflict outcome. In the relationship between perceived conflict and conflict outcome, conflict management had a complete mediating effect while expressed conflict had a partial mediating effect. Lastly, the perception of university dormitories did not have a moderating effect for the influence of conflict management on conflict outcome.

Urbanization brings many challenges such as traffic, housing, and environment. To solve these problems, researchers are working on new transportation systems like urban air mobility (UAM). UAM aircraft should fly safely without burdening the existing air traffic system in the early stage of low-density operation. The airspace should also be managed and operated efficiently. Therefore it is important to make urban air traffic predictable by using corridors and collecting data on low-density operations in the early stage. For this purpose various simulations are needed before operation to create scenarios that estimate potential collisions between UAM aircraft and to evaluate the risks of aircraft spacing, loss of separation (LoS), and near mid air collision (NMAC). This paper focuses on identifying the requirements and considerations for setting separation standards for urban air traffic based on the results of studies.

The safety related components in the nuclear power plant should be designed to withstand the seismic load. Among these components the integrity of reactor internals under earthquake load is important in stand points of safety and economics, because these are classified to Seismic Class I components. So far the modelling methods of reactor internals have been investigated by many authors. In this paper, the dynamic behaviour of reactor internals of Yong Gwang 1&2 nuclear power plants under SSE(Safe Shutdown Earthquake) load is analyzed by using of the simpled Global Beam Model. For this, as a first step, the characteristic analysis of reactor internal components are performed by using of the finite element code ANSYS. And the Global Beam Model for reactor internals which includes beam elements, nonlinear impact springs which have gaps in upper and lower positions, and hydrodynamical couplings which simulate the fluid-filled cylinders of reactor vessel and core barrel structures is established. And for the exciting external force the response spectrum which is applied to reactor support is converted to the time history input. With this excitation and the model the dynamic behaviour of reactor internals is obtained. As the results, the structural integrity of reactor internal components under seismic excitation is verified and the input for the detailed duel assembly series model could be obtained. And the simplicity and effectiveness of Global Beam Model and the economics of the explicit Runge-Kutta-Gills algorithm in impact problem of high frequency interface components are confirmed.
