In order to analyze the shifts in the volume and profits of Computed Tomography(CT) and Magnetic Resonance Imagine(MRI) utilization for a year before and after the implementation of insurance coverage for CT, this study has been undertaken examining CT and MRI cost data from 'Y' University Hospital situated in Seoul, Korea. Following are the results of this study : 1. The medical insurance payment for CT, implemented on January 1, 1996, increased CT utilization from January 1996 to April 1996 due to low insurance premiums : however, from May 1996 the number of CT cases significantly decreased as a result of strengthened medical cost reviews and the new 'Detailed standards for approval of CT' announced near the end of April 1996 by the insurer. 2. Since the implementation of insurance coverage for CT, CT fee reduction rates for reimbursements by the insurer to the hospital were 50% and 40% for January and February, respectively, and 31% and 15% for March and April. A significant point in the lowering of the reduction rate was reached in May at 11% : furthermore, since June the reduction rate fell below the average reduction rate for reimbursements for all procedures. If the 'Detailed standards for approval of CT' had been announced before the implementation of insurance coverage for CT, CT utilization would not have been so high due to the need to meet those 'standards'. In addition, loss of hospital profits resulting from the reduction for reimbursements would not have occurred. 3. The shifts in MRI utilization showed that there was no particular change with the beginning of insurance coverage for CT, and the introduction of the 'Detailed standards for approval of CT' made MRI utilization increase because MRI is free of restrictions imposed by the insurer. 4. The relationship between CT utilization and MRI utilization shoed that they were supplementary to each other before insurance coverage for CT, but that CT was substituted for MRI because of strengthened medical cost reviews after the beginning of insurance coverage for CT. 5. The shifts in volume by patient characteristics showed that the number of inappropriate case patients, according to the insurer's "Standards for approval", decreased more than the number of appropriate case patients after the introduction of insurance coverage for CT. Therefore, the health insurance fee schemes for CT have influenced patient care. 6. The shifts in profits from CT utilization showed a net profit decrease of 31.6%. In order to match the pre-coverage profit level, 5,471 more cases would need to be seen and productivity would need to be increased by 32.7%. This profit decrease resulted from a decrease of CT utilization and low reimbursements. With insurance coverage, net profits from CT were 24.4%, and a margin of safety ratio was 39.6%. Because of the net profits and margin of safety ratio, CT utilization fees for insured appropriate cases could not be considered inappropriate. 7. The shifts in profits from MRI utilization before and after the introduction of CT coverage showed that in order to match pre-CT coverage profit levels, 2,011 more cases would need to be seen and productivity would need to be increased by 9.2%. The reasons for needing to increase the number of cases and productivity result from cost burdens created by adding new MRI units. But with CT coverage already begun, MRI utilization increased. Combined with a minor increase in the MRI fee schedule, MRI utilization showed a net profit increase of 18.5%. Net profits of 62.8% and a 'margin of safety ratio' of 43.1% for MRI utilization showed that the hospital relied on this non-covered procedure for profits. 8. The shifts in profits from CT and MRI utilization showed the net profits from CT decreased by 2.33 billion Won while the net profits from MRI increased by 815.7 million Won. Overall, these two together showed a net profit decrease of 1.51 billion Won. The shifts in utilization showed a functional substitution relationship, but the shifts in profits did not show a substitutionary relationship. From these results, We can conclude that if insurance is to be expanded to include previously uncovered procedures using expensive medical equipment, detailed standards should be prepared in advance. The decrease in profits from the shifts in coverage and changes in fees is a difficult burden that should be shared, not carried by the hospital alone. Also, a new or improved fee schedule system should include revised standards between items listed and the appropriateness of the fee schedule should constantly be ensured. This study focused on one university hospital in Seoul and is therefore limited in general applicability. But it is valuable for considering current issues and problems, such as the influence of CT coverage on hospital management. Future studies will hopefully expand the scope of the issues considered here.

Glow방전법에 의해서 SiH_4를 분해하여 α-Si 박막을 얻을수 있는 장치를 제작하였다. 이 SiH_4기체는 수소기체속에서 10%로 희석되였으며, 진공방전함속에서 rf 전압에 의하여 분해된 Si는 유리기판위에 증착된다. α-Si박막은 1~1.6 A˚/sec의 증착율로 약 7000 A˚의 두께까지 증착되였다. α-Si 박막의 흡수계수는, 2.3 eV의 photon energy 영역에서 약 10^4 cm^-1이고, 그 optical gap은 약 2.1 eV였다. 이 박막의 증착율은 전극간격에 따라 변하고 있으나, 최적전극간격과 기체유입량은 각각 2.6cm와 1~2cc/min였다. Apparatus capable of producing α-Si film by the glow discharge method was designed and constructed in this study. The monosilane gas which is diluted in H_2 gas to 10% is decomposed in the reaction chamber by rf oscillation. The apparatus is composed of a reaction chamber, a rf generator, a cooling system, etc. The α-Si thin film is produced at a deposition rate of 1~1.6 A˚/sec to a thickness of about 7000 A˚. Its absorption coefficient is about 10^4 cm^-1 in the photon energy region of ~2.3 eV, and its optical gap is about 2.1 eV. The deposition rate for the film is controlled by varying the distance between electrode and substrate. The optimum distance and gas flow is about 2.6 cm and 1~2 cc/min, respectively.

SiH_4 기체에 PH_3 및 B_2H_6 기체를 0.7% 체적비로 혼합하여 rf glow 방전법으로 n형 및 p형 a-Si:H 박막을 기판온도 120℃에서 제작하여, 광투과도 측정, 열처리에 따른 전기 전도도의 변화 등을 조사하여 이들의 doping 효과를 연구하였다. n형, p형 및 undoped a-Si:H 박막의 optical gap은 각각 1.73eV, 1.86eV 및 1.86eV로 doping이 많이 이루어질수록 줄어 들었다. 250℃에서 열처리한 시료들의 상온에서의 전도도는 각각 2×10^-2Ω^-1㎝^-1, 5×10^-8Ω^-1㎝^-1, 5×10^-7Ω^-1㎝^-1이었고, 활성화 에너지 ??E는 각각 0.16eV, 0.49eV 및 0.48eV이었다. 300℃에서 열처리한 결과, ??E는 줄어 들고 전도도는 증가하였다. 350℃ 및 450℃에서 열처리한 결과 dehydrogenation 효과로 인하여 n형과 p형은 서로 상반되는 결과를 보였다. 즉, n형 시료의 전도도는 감소하고 ??E는 증가하였지만, P형 시료의 전도도는 증가하고 ??E는 감소하였다. 저온 영역에서 구한 n형 시료의 전도도로부터 hopping 활성화 에너지를 구한 결과 0.085eV이었다. Thin n-type and p-type a-Si:H films were prepared by rf glow discharge decomposition of silane mixed with 7×10^-3 parts per volume of phospine or diborane. All specimens were deposited on glass substrates held at 120℃. In order to determine the doping effects the opital absorption and dc conductivity of these specimens were measured after annealing at various temperatures. The optical gap was 1.73eV in the case of the n-type specimens, 1.80eV for the p-type, and 1.86eV undoped. This showed that the gap width decreased as the doping increased. The room temperatuer conductivities of these specimens annealed at 250℃ were 2×10^-2Ω^-1㎝^-1, 5×10^-8Ω^-1㎝^-1, and 5×10^-7Ω^-1㎝^-1, respectively, and the activation energies, ??E, of these specimens were 0.16eV, 0.49eV, and 0.48eV, respectively. For specimens annealed at 300℃, ??E decreased and the conductivity increased. When these specimens were annealed at 350℃ and 450℃, dehydrogenation caused opposite effects on the n-type and p-type specimens; the conductivities of n-type specimens decreased and ??E increased, but the conductivities of p-type specimens increased and ??E decreased.From an investigation of the temperature dependence of the conductivity of the n-type specimen in the low temperature region, we determined that the hopping activation energy was 0.085eV.

태양 전지의 제작시 투명 전극막으로 쓰이는 ITO 박막을 제조하기 위하여 cathode 접지 방식의 전자총을 가진 정전 편향 집속형의 전자선 증착 장치를 제작하였다. 가속전압이 0∼15kV, 필라멘트 전류가 0∼28A, 두 전극판 사이의 간격이 11mm, anode와 deflector 사이의 간격이 30mm인 최적 실험조건하에서 생성된 전자선 spot의 크기는 길이가 20mm 폭이 1mm였으며, 전자선의 출력은 약 400W였다. 이 전자선 증착 장치를 이용하여 1600℃까지의 증발 온도를 가진 도체와 절연체 등을 쉽게 증착시킬 수 있었으며, 만드어진 ITO 박막은 약 5000Å의 두께에서 10^-1∼10^-2Ω·㎝의 비저항과 95%의 광투과율을 갖는다. An electron beam evaporator with a cathode grounded type electron gun was designed and constructed in order to deposit ITO thin films for photovoltaic applications. The optimum condition was observed with electode spacing of 11mm, 30mm between anode and deflector, a cathode inner diameter of 3mm and an anode inner diameter of 5mm. As the accelerating voltage varies from 0 to 15kV and ghe filament current from 0 to 28 A, the minimum electron beam spot has a 20mm length, and 1mm width and the output power ranges from 0 to 400W under the above optimum conditions. We can deposit materials whose evaporation temperature is over 1600℃ using this evaporator. And as a result ITO thin film showed a low resistivity of 10^-1∼10^-2Ω·㎝ and the transmittance of 95%.

정희정(Chung Hee Chung),구철모(Koo Chul mo),정남호(Chung Nam ho) 대한관광경영학회 2017 觀光硏究 Vol.32 No.2

최근 기술의 발전에 따라 관람객의 유용한 경험을 위해 많은 박람회에서 새로운 정보기술을 도입하고 있다. 그러나 박람회의 정보기술 중 NFC 도입에 관한 연구는 매우 드물다. 따라서 본 연구는 최근 박람회에서 주로 도입하고 있는 정보기술 중 하나인 NFC(Near Field Communication) 서비스 기술에 대한 관람객들의 지속적인 사용의도를 통합기술수용모형과 신뢰를 결합하여 파악하고자 한다. 본 연구는 2013 오송 국제 화장품·뷰티 박람회의 관람객을 대상으로 총 310부의 표본을 수집하여 분석에 사용하였다. 분석결과, 성과기대, 노력기대, 사회적 영향이 NFC 서비스의 지속적인 사용의도에 유의한 영향을 미치는 것으로 나타났다. 또한 NFC 신뢰는 성과기대에 유의한 영향을 미치는 것으로 나타났다. 이러한 연구결과를 바탕으로 본 연구는 이론적, 실무적 시사점을 제공한다. Recently, as technology advances, many exhibitions have introduced new information technology for their visitors’ useful experience. However, there is little research that has investigated this phenomenon. Thus, this study explains the process of continuous adoption of near field communication (NFC) service as new information technology by the users of exhibition visitor. We employed UTAUT model incorporating the concept of trust, and then we proposed comprehensive research model. Though on-site survey, this study collected 310 samples from those using NFC service in an exhibition and analyzed the data. This study found that performance expectancy, effort expectancy, social influence had an influence on NFC service continuous intention of use. Additionally, trust had an influence on performance expectancy. These findings have theoretical and practical implications.

The purpose of this study is to classify elderly patient in long-term care facilities using RUG(Resource Utilization Group)-Ⅲ. It is designed by measuring patient medical characteristics and medical staff time. Elderly patients are classified into 7 categories by clinical(medical and behavioral) hierarchical typology of patients. Through the tertiary split, all 44 groups are formulated. This classification is explained by each patient resource(staff time) utilization level which is called CMI(Case-Mix Index). Major findings are as follows ; 1. The objects in this study were classified into 35 groups out of 44 groups. The most frequent category is clinical complex category(CCC; 38.9%). And extensive service category(ESC; 18.8%), reduced physical function category(RPC; 13.1%), special rehabilitation category(SRC; 12.8%), and impaired cognitive category(ICC; 0.96%) are followed. 2. The mean of total CMI was 1.02±0.36, ranging from 0.68 to 1.44(1 vs 2.12). The mean of CMI of SRC is only 1.17 which should be the highest. The means of ESC and SCC are equally 1.20. The means of CMI of CCI, ICC, BPC, and RPC were 0.90, 0.75, 0.83 and 0.96, respectively. 3. The validity of this classification was tested. Trend-test using Regression Analysis was done in the secondary split level. SCC, CCC, ICC, and RPC which covered 68.4% of this research objects showed linear trend of CMI in interim classification. This results were statistically significant. 4. In clinical hierarchy, the trend were showed linearity. But the multiple comparison of categories using Scheffe-test showed that SRC, ESC and SCC had same level of CMI means and CCC and ICC, too. This results were statistically significant. Classifying elderly patients with RUG-Ⅲ, the results showed partly linear trend in clinical hierarchy and in interim classification in conclusion. But, in clinical hierarchy, it was failed to show the consistent order of CMI. It can be explained by two reasons. One is that this research subjects were overlapped in each clinical hierarchy group. And the other is that the some of the characteristics for clinical hierarchy is not appropriate for them. For the further study, it needs to have proper sample size and to modify RUG-Ⅲ to K-RUG to consider our medical environment.
