Objectives : The purpose of this study is to investigate the clinical effectiveness of Korean medical combination treatment for cervical disc herniation. Methods : This is an observational study. 102 patients diagnosed with cervical disc herniation by MRI (Magnetic Resonance Imaging) were investigated from January, 2015 through to December, 2015 at Daejeon Jaseng Hospital of Korean Medicine. They were sorted according to the distribution of sex, age, causing factor, the period of disease, admission day and pain area. All patients were treated with acupuncture, Chuna treatment, and herbal therapy and physical therapy during the admission period. After treatment, NRS (Numeric Rating Scale), NDI (Neck Disability Index) and EQ-5D were assessed to evaluate the treatment efficacy. Results : There were more females than Males with a ratio of 1 : 1.37, the age of fifty was the most with 35.29 %, reason unknown was the most with 72.55 % and the subacute stage was the most with 38.24 %. According to disc herniation types, patients with protruded disc types were the most with 66.67 % and a lesion of C5/6 was the most with 41.18 %. For patients diagnosed with cervical disc herniation, neck and shoulder pain NRS decreased from $6.43{\pm}1.77$ to $3.96{\pm}1.96$(p<0.001) and radiating pain NRS decreased from $5.64{\pm}1.96$ to $3.57{\pm}1.88$ (p<0.001). NDI decreased from $41.72{\pm}14.04$ to $30.84{\pm}15.34$(p<0.001), and the EQ-5D index increased from $0.68{\pm}0.17$ to $0.79{\pm}0.14$(p<0.001) after treating cervical disc patients. Conclusion : Korean medical combination treatment might be effective in decreasing pain and raising the life quality of patients with cervical disc herniation.

본 연구는 산림치유를 불교적 관점에서 분석하여 그 효과를 향상시키는데 목적이 있다. 숲은 어떤 종교보다도 불교와 깊은 인연과 밀접한 관계를 맺고 있다. 붓다의 일생은 숲과 나무와 이어져 있으며, 이는 숲의 영성적 본질과 역할에 기인한다. 치유(治癒)란 심신(心身)의 고통문제를 다루는 것으로 불교에서는 실천수행법을 통해서 해결한다. 감각제어에 대한 생각, 탐욕, 좋지 않는 감정 등 망상이 일어나는 현상을 정확하게 이해함으로써 불필요한 자극이나 외부대상을 추구하려는 욕망에서 벗어나게 해준다. 인간은 아름다운 자연경관 속에서 오감(五感)을 통해 감각기관상의 쾌적함과 즐거움을 얻을 수 있으며, 마음의 안정을 찾게 된다. 산림(숲)에 들어가면 오감의 작동으로 제 6 의식(意識)이 망상(妄想)을 자라지 못하도록 하는 좋은 환경들이 숲속에 들어있기 때문이다. 본 연구는 산림이라는 자연 환경적 치유인자와 불교이론에 근거한 효과를 선행연구를 토대로 분석한 예비연구다. 불교가 산림치유에 미치는 치유효과를 극대화할 수 있는지를 고찰한 결과, 기존 산림치유기법과 더불어 활성화에 기여할 수 있음을 확인하였다. 그 효과성 검증은 차후 실험연구 등을 통한 후속연구과제로 남겨두고 본 연구가 산림치유효과의 활성화에 기여할 수 있기를 기대한다.

Purpose - Recently, the importance of rapid change in business models is more and more increasing as the change of information technology environment. Therefore, a variety of business models have emerged. On the other hand, there is no company that can generate revenue. Many enterprises are still maintained while they are changing only their appearance of the business model. Business model is important in e-commerce. However, a lot of researches are targeted only in Web sites. Thus, e-commerce companies do not have the infrastructure for measuring and business models. The purpose of paper is to evaluate factors which are related with the structuring of the e-commerce success. And it proposed a financial items and non-financial items. From the perspectives of administrators and managers, the paper researches the possibility for E-Commerce Evaluation Model as a valuable criteria in measuring business model. Research design, data and methodology - The methods are taken by the classification for the type of business-to-business transactions, transactions subject, and the degree of integration and innovation capabilities. Financial and Non-financial value is used to build E-Commerce Evaluation Model. Evaluation items in Administration's perspective are composed with enhance the effectiveness of the mission, improving efficiency of the administration, and control of costs. Evaluation items in the customer's perspective were measured by customer participation and cooperation with customer Satisfaction. In the case of researching the information system's perspective, three criteria are used such as adequacy of the development process, improvement of the quality of service, and maintenance of standardized information technology. In researching for the ICT competence's perspective, evaluation items were composed of enhanced user capabilities, utilizing new technologies, and empowerment of information workers. Results - In this paper, E-Commerce Evaluation Model with financial and non-financial perspectives shows the possibility to be criteria in the case of measuring business model. Moreover, it gives the positive expectation to be successful criteria. But the research may have ambiguity in its essential concept because it cannot avoid the limitation in selecting evaluation tools from merely the model. It is impossible to exclude the possibility in omitting specific properties which may take place in actual case study. Therefore, In hereafter research, it is necessary to include actual case study research in selecting evaluation tools in order to improve the limit point. Actual measurement items which are derived from actual case study should be subdivided, and it would be more effective to complete the research. Conclusions - In rapid change in business models, there are various kinds of business models. But it is general situation that companies which adopted business models have not brought in revenue. For this reason, E-Commerce Evaluation Model is needed as an important factor for the structuring of the e-commerce success. Although it has the limitation in selecting evaluation tools from model, E-Commerce Evaluation Model proposes the implication for measuring business models as a valuable criteria.

Numerous factors are known to affect the accuracy of elastomeric impression materials. Factor often overlooked is the quality of the bond between putty and wash during corrective reline impression technique. The putty-wash bond strength must be strong enough to over-come the local stress at putty-wash interface. It is not always possible to avoid saliva contamination in making corrective wash impres-sion. And putty preliminary impression material con be used as a template for provisional restoration. Human saliva and the residual monomer of autopolymerizing acrylic resin are thought to affect the bond strength and the failure type. This study examined the effect of contaminants like human saliva, and residual resin monomer on the putty-wash bond strength and the effectiveness of treatment. 1. Of the tested three brands of Vinyl Polysiloxane impession meterial, Express Exhibited the greatest bond strength followed by Eamix and Perfect showed the lowest putty-wah bond strength. 2. Coating the putty substrates with human saliva did not produce decreased failure load in all the breands of Vinyl Polysiloxane impression meterail. 3. Of the three brands of VPS impression material that were exposed to methhylmethacry-late resin(Jet), only the putty-wash bond strength of the Perfect group diminished signifi-cantly. Moreover, all the specimens from group C of Perfect exhibited adhesive failure. 4. Exposing the substrates to ethylmethacrylate resin(SNAP. diminished the putty-wash bond strength significantly. With Perfect and Examix, failure occurred cohesively through the light-body, whereas with Express, failure occurred adhesive-cohesively. 5. Removing approximately 1mm thickness of the contaminated putty interface was the most effective treatment in countering the undesirable effect caused by residual resin monomer. The putty-wash bond strength of the groups that were treated with 1mm even putty reduction was not significantly different from those of control groups. With Perfect and Examix, cleaning the specimens with gauze soaked in 70% isopropyl alcohol increased the putty-wash bond strength, but was not as effective as 1mm even reduction of contaminated putty substrates. With Express, 70% isoproryl alcohol treatment exhibi0ted comparable putty-wash bond strength to that of control group.

Currently the oriental medical care services in the health centers is getting popularity because of their unique aspects which western medicine can not cover. This study was conducted to speculate the current status of oriental medical care services in health centers and possibility of how to effectively provide the oriental medical care services(or traditional medical care services) in health centers. For the study, the survey questionnaires were distributed to all 269 health centers and 138(51.3%) of them were collected. Eight of the collected were inadequate for the analysis and 130 of 269 questionnaires were finally chosen for the study. The SPSS/PC WIN 8.0 was used for the statistical analysis. The results are as follows. First, 91 out of 130 sample health centers(70%) are providing oriental medical care services. The results show that the willingness of the directors and the public awareness in community are the most important factors to provide oriental medical care services in health centers. In contrast, the lack of cooperative efforts between western and oriental medical doctors and the lack of government supports are considered as factors that intervene the oriental medical care services in health centers. About 80% of the sample health centers respond that the government supports is needed for oriental medical care services in health centers. Second, it was asked to the directors of 39 health centers which do not provide oriental medical care services regarding their future plan to include the services. About 70% of health centers respond that no plan is available now. They acknowledge that the demand on the services is the most important factor to consider the oriental services as their future medical services. Third, 69.2% of the oriental medical doctors in health centers are public health doctor. 95.6% of the sample health centers have space for the oriental medical care services in their facilities and some health centers provide the services through the private clinics nearby facilities. Finally, the surveyors consider both budgetary constraints and difficulty in recruiting doctors as barriers for the effective oriental medical care services in health centers. Finally, t-test and LSD were employed to find out the difference among several groups. The analysis shows statistically significant difference among groups about their recognition on health care policy, health care system, and effectiveness of oriental medical care services. To be conclude, the study shows the necessity of oriental medical care services in health centers. To do so, the government supports, cooperative efforts between oriental and western medical doctors, and providing job security for doctors should proceed to provide effective oriental medical care services in health centers.

Purpose: For periodontal tissue engineering, it is a primary requisite and a challenge to select the optimum types of cells, properties of scaffold, and growth factor combination to reconstruct a specific tissue in its natural form and with the appropriate function. Owing to fundamental disadvantages associated with using a two-dimensional substrate, several methods of seeding cells into three-dimensional scaffolds have been reported and the authors have asserted its usefulness and effectiveness. In this study, we explore the cell attachment of periodontal ligament fibroblasts on nanohydroxyapatite (n-HA) scaffold using avidin biotin binding system (ABBS). Methods: Human periodontal ligament fibroblasts were isolated from the health tooth extracted for the purpose of orthodontic procedure. HA nanoparticles were prepared and $Ca(NO_3)_2-_4H_2O$ and $(OC_2H_5)_3P$ were selected as precursors of HA sol. The final scaffold was 8 mm in diameter and 3 mm in height disk with porosity value of 81.55%. $1{\times}10^5$ periodontal ligament fibroblasts were applied to each scaffold. The cells were seeded into scaffolds by static, agitating and ABBS seeding method. Results: The number of periodontal ligament fibroblasts attached was greater for ABBS seeding method than for static or agitating method (P<0.05). No meaningful difference has been observed among seeding methods with scanning electron microscopy images. However, increased strength of cell attachment of ABBS could be deduced from the high affinity between avidin and biotin ($Kd=10^{-15}\;M$). Conclusions: The high-affinity ABBS enhances the ability of periodontal ligament fibroblasts to attach to three-dimensionally constructed n-HA scaffold.

This study was intended to assess the need of home nursing care and analyze the effect of home nursing care, and find out the problems during the performance of home nursing care for the chronic patients among the low-income people in urban area. Data collection by interview was carried out from Nov. 1991 to Jul. 1992. The main results were as follows; 1) Total subjects for the need assessment of home nursing care were 123 households wi th 488 persons in a urban poor area. Over half of households $(57.7\%)$ was teenage family. The overall living conditions were poor and the average monthly income was 580 thousands won. $74.8\%$ of subjects was covered by medical care insurance and only $4.7\%$ was covered by public assistance. The morbidity rate was $8.2\%$ among 488 subjects and $27.5\%$ of them was not treated at all, $30\%$ was treated in utilizing pharmacies or local clinics. 2) The subjects of home nursing care were 46 with Hypertension or DM who agreeded the participation of study among registered patients at a public health center in Incheon. Home visiting was performed at intervals per one month for one year. Most of them were the elder(mean age=61 years) and long term patients(7.8 years continued). Home nursing care was effective. That is, blood pressure(including systolic and diastolic pressure) was significantly reduced (t(n=22)=2.31, P=.031, t(n=24)=4.16, P=.000 respectively) and knowledge of disease(t(N=46)=-7.63, P=.000), attitude of disease (t(N =46) = -4.92, P=.000), and self-care(t(N =46) = -4.89, P= .000) were significantly improved through home nursing care. But there was no difference in blood sugar for diabetics between the beginning and the end of visits. At the beginning of visit for home nursing care, sex$(\beta=-0414,\;t=-3.012)$ and nursing need({3=.310, t=2.164) were influencing self-care, and duration of disease$(\beta=.297,\;t=2.106)$ and nursing need $(\beta=.385, t=20417)$ were influencing blood pressure, blood sugar level. Namely, the subjects who were male and had higher nursing need showed better self-care and the longer duration of disease and the higher nursing need were relationship with the better blood pressure and blood sugar level. At the end of visit for home nursing care after one year, the blood pressure and blood sugar level was influenced by age $(\beta.320,\;t= 2.242)$, duration of disease ($(\beta.352,\;t= 2.395)$ and nursing need $(\beta=.350,\;t=2.623)$ and self-care had no influencing factor. The higher age and the longer duration of disease and the higher nursing need were relationship with the better blood pressure and blood sugar level. 3) The problems that were found out during the performance of home nursing care were the absent of useful protocols for services and the clear evaluation base, and the difficulty of teaching elders who were the major part of our subjects.
