The purpose of this study is the investigation of the effects of user participation, network effect, social influence, and usefulness on stickiness and continued use on Internet communities. In this research, stickiness refers to repeat visit and visit duration to an Internet community. Continued use means the willingness to continue to use an Internet community in the future. Internet community-based companies can earn money through selling the digital contents such as game, music, and avatar, advertizing on internet site, or offering an affiliate marketing. For such money making, stickiness and continued use of Internet users is much more important than the number of Internet users. We tried to answer following three questions. Fist, what is the effects of user participation on stickiness and continued use on Internet communities? Second, by what is user participation formed? Third, are network effect, social influence, and usefulness that was significant at prior research about technology acceptance model(TAM) still significant on internet communities? In this study, user participation, network effect, social influence, and usefulness are independent variables, stickiness is mediating variable, and continued use is dependent variable. Among independent variables, we are focused on user participation. User participation means that Internet user participates in the development of Internet community site (called mini-hompy or blog in Korea). User participation was studied from 1970 to 1997 at the research area of information system. But since 1997 when Internet started to spread to the public, user participation has hardly been studied. Given the importance of user participation at the success of Internet-based companies, it is very meaningful to study the research topic of user participation. To test the proposed model, we used a data set generated from the survey. The survey instrument was designed on the basis of a comprehensive literature review and interviews of experts, and was refined through several rounds of pretests, revisions, and pilot tests. The respondents of survey were the undergraduates and the graduate students who mainly used Internet communities. Data analysis was conducted using 217 respondents(response rate, 97.7 percent). We used structural equation modeling(SEM) implemented in partial least square(PLS). We chose PLS for two reason. First, our model has formative constructs. PLS uses components-based algorithm and can estimated formative constructs. Second, PLS is more appropriate when the research model is in an early stage of development. A review of the literature suggests that empirical tests of user participation is still sparse. The test of model was executed in the order of three research questions. First user participation had the direct effects on stickiness(${\beta}$=0.150, p<0.01) and continued use (${\beta}$=0.119, p<0.05). And user participation, as a partial mediation model, had a indirect effect on continued use mediated through stickiness (${\beta}$=0.007, p<0.05). Second, optional participation and prosuming participation significantly formed user participation. Optional participation, with a path magnitude as high as 0.986 (p<0.001), is a key determinant for the strength of user participation. Third, Network effect (${\beta}$=0.236, p<0.001). social influence (${\beta}$=0.135, p<0.05), and usefulness (${\beta}$=0.343, p<0.001) had directly significant impacts on stickiness. But network effect and social influence, as a full mediation model, had both indirectly significant impacts on continued use mediated through stickiness (${\beta}$=0.11, p<0.001, and ${\beta}$=0.063, p<0.05, respectively). Compared with this result, usefulness, as a partial mediation model, had a direct impact on continued use and a indirect impact on continued use mediated through stickiness. This study has three contributions. First this is the first empirical study showing that user participation is the significant driver of continued use. The researchers of information system have hardly studies user participation since late 1990s. And the researchers of marketing have studied a few lately. Second, this study enhanced the understanding of user participation. Up to recently, user participation has been studied from the bipolar viewpoint of participation v.s non-participation. Also, even the study on participation has been studied from the point of limited optional participation. But, this study proved the existence of prosuming participation to design and produce products or services, besides optional participation. And this study empirically proved that optional participation and prosuming participation were the key determinant for user participation. Third, our study compliments traditional studies of TAM. According prior literature about of TAM, the constructs of network effect, social influence, and usefulness had effects on the technology adoption. This study proved that these constructs still are significant on Internet communities.

Within the traditional medical delivery system, patients residing in medically vulnerable areas, those with body movement difficulties, and nursing facility residents have had limited access to good healthcare services. However, Information and Communication Technology (ICT) provides us with a convenient and useful means of overcoming distance and time constraints. ICT is integrated with biomedical science and technology in a way that offers a new high-quality medical service. As a result, rapid technological advancement is expected to play a pivotal role bringing about innovation in a wide range of medical service areas, such as medical management, testing, diagnosis, and treatment; offering new and improved healthcare services; and effecting dramatic changes in current medical services. The increase in aging population and chronic diseases has caused an increase in medical expenses. In response to the increasing demand for efficient healthcare services, a telehealth service based on ICT is being emphasized on a global level. Telehealth services have been implemented especially in pilot projects and system development and technological research. With the service about to be implemented in earnest, it is necessary to study its overall acceptance by consumers, which is expected to contribute to the development and activation of a variety of services. In this sense, the study aims at positively examining the structural relationship among the acceptance factors for telehealth services based on the Technology Acceptance Model (TAM). Data were collected by showing audiovisual material on telehealth services to online panels and requesting them to respond to a structured questionnaire sheet, which is known as the information acceleration method. Among the 1,165 adult respondents, 608 valid samples were finally chosen, while the remaining were excluded because of incomplete answers or allotted time overrun. In order to test the reliability and validity of the assessment scale items, we carried out reliability and factor analyses, and in order to explore the causal relation among potential variables, we conducted a structural equation modeling analysis using AMOS 7.0 and SPSS 17.0. The research outcomes are as follows. First, service quality, innovativeness of medical technology, and social influence were shown to affect perceived ease of use and perceived usefulness of the telehealth service, which was statistically significant, and the two factors had a positive impact on willingness to accept the telehealth service. In addition, social influence had a direct, significant effect on intention to use, which is paralleled by the TAM used in previous research on technology acceptance. This shows that the research model proposed in the study effectively explains the acceptance of the telehealth service. Second, the research model reveals that information privacy concerns had a insignificant impact on perceived ease of use of the telehealth service. From this, it can be gathered that the concerns over information protection and security are reduced further due to advancements in information technology compared to the initial period in the information technology industry, and thus the improvement in quality of medical services appeared to ensure that information privacy concerns did not act as a prohibiting factor in the acceptance of the telehealth service. Thus, if other factors have an enormous impact on ease of use and usefulness, concerns over these results in the initial period of technology acceptance may become irrelevant. However, it is clear that users' information privacy concerns, as other studies have revealed, is a major factor affecting technology acceptance. Thus, caution must be exercised while interpreting the result, and further study is required on the issue. Numerous information technologies with outstanding performance and innovativeness often attract few consumers. A revised bill for those urgently in need of telehealth services is about to be approved in the national assembly. As telemedicine is implemented between doctors and patients, a wide range of systems that will improve the quality of healthcare services will be designed. In this sense, the study on the consumer acceptance of telehealth services is meaningful and offers strong academic evidence. Based on the implications, it can be expected to contribute to the activation of telehealth services. Further study is needed to assess the acceptance factors for telehealth services, such as motivation to remain healthy, health care involvement, knowledge on health, and control of health-related behavior, in order to develop unique services according to the categorization of customers based on health factors. In addition, further study may focus on various theoretical cognitive behavior models other than the TAM, such as the health belief model.

Developing an agile recommender system for nomadic users has been regarded as a promising application in mobile and ubiquitous settings. To increase the quality of personalized recommendation in terms of accuracy and elapsed time, estimating future context of the user in a correct way is highly crucial. Traditionally, time series analysis and Makovian process have been adopted for such forecasting. However, these methods are not adequate in predicting context data, only because most of context data are represented as nominal scale. To resolve these limitations, the alignment-prediction algorithm has been suggested for context prediction, especially for future context from the low-level context. Recently, an ontological approach has been proposed for guided context prediction without context history. However, due to variety of context information, acquiring sufficient context prediction knowledge a priori is not easy in most of service domains. Hence, the purpose of this paper is to propose a novel context prediction methodology, which does not require a priori knowledge, and to increase accuracy and decrease elapsed time for service response. To do so, we have newly developed pattern-based context prediction approach. First of ail, a set of individual rules is derived from each context attribute using context history. Then a pattern consisted of results from reasoning individual rules, is developed for pattern learning. If at least one context property matches, say R, then regard the pattern as right. If the pattern is new, add right pattern, set the value of mismatched properties = 0, freq = 1 and w(R, 1). Otherwise, increase the frequency of the matched right pattern by 1 and then set w(R,freq). After finishing training, if the frequency is greater than a threshold value, then save the right pattern in knowledge base. On the other hand, if at least one context property matches, say W, then regard the pattern as wrong. If the pattern is new, modify the result into wrong answer, add right pattern, and set frequency to 1 and w(W, 1). Or, increase the matched wrong pattern's frequency by 1 and then set w(W, freq). After finishing training, if the frequency value is greater than a threshold level, then save the wrong pattern on the knowledge basis. Then, context prediction is performed with combinatorial rules as follows: first, identify current context. Second, find matched patterns from right patterns. If there is no pattern matched, then find a matching pattern from wrong patterns. If a matching pattern is not found, then choose one context property whose predictability is higher than that of any other properties. To show the feasibility of the methodology proposed in this paper, we collected actual context history from the travelers who had visited the largest amusement park in Korea. As a result, 400 context records were collected in 2009. Then we randomly selected 70% of the records as training data. The rest were selected as testing data. To examine the performance of the methodology, prediction accuracy and elapsed time were chosen as measures. We compared the performance with case-based reasoning and voting methods. Through a simulation test, we conclude that our methodology is clearly better than CBR and voting methods in terms of accuracy and elapsed time. This shows that the methodology is relatively valid and scalable. As a second round of the experiment, we compared a full model to a partial model. A full model indicates that right and wrong patterns are used for reasoning the future context. On the other hand, a partial model means that the reasoning is performed only with right patterns, which is generally adopted in the legacy alignment-prediction method. It turned out that a full model is better than a partial model in terms of the accuracy while partial model is better when considering elapsed time. As a last experiment, we took into our consideration potential privacy problems that might arise among the users. To mediate such concern, we excluded such context properties as date of tour and user profiles such as gender and age. The outcome shows that preserving privacy is endurable. Contributions of this paper are as follows: First, academically, we have improved sequential matching methods to predict accuracy and service time by considering individual rules of each context property and learning from wrong patterns. Second, the proposed method is found to be quite effective for privacy preserving applications, which are frequently required by B2C context-aware services; the privacy preserving system applying the proposed method successfully can also decrease elapsed time. Hence, the method is very practical in establishing privacy preserving context-aware services. Our future research issues taking into account some limitations in this paper can be summarized as follows. First, user acceptance or usability will be tested with actual users in order to prove the value of the prototype system. Second, we will apply the proposed method to more general application domains as this paper focused on tourism in amusement park.

This study is carrying out a before and after experiment design for the non-equal comparative group to identify the effects of the breast self-examination education on breast self-examination participant education compliance and health promotion in women. The subject of this study was 58 women residing in Chungju. Their age ranged from 20 to 40. These women were not pregnant or did not breast feed, as well as they did not have any breast disease, at the time of survey. They were available for the response to the questionnaires, and understood the purpose of this study. They also agreed to participate in the study, and responded to the 3rd time questionnaires to the end. Thus, brochures and lectures were provided side by side to a group of 19 of those women, and only brochures were provided to another group of 39 of those women. With regard to education, a brochure and a program using a breast model were applied. Then, the frequency of the breast self examination compliance, breast self examination capability and the relations between the breast self examination and activities to promote health were measured, before the education, after 4 weeks of education and after 12 weeks of education. Before education and after 4 weeks of education. I collected the questionnaires myself visiting them, and after 12 weeks of education, the questionnaires were collected by mail. In relation to the study tool, the breast self examination activity was measured by two measuring tools: breast self examination activity frequency and breast self examination compliance capability. As for the frequency, the number of self examination for the period of 3 months, before the questionnaire survey, was measured in the form of self report. In relation to the tool to measure the breast self examination capability, the BSEPRI tool, which was developed by Wood in 1994, was used. Here, as the score was higher, the capability was indicated to be higher. The translated and revised version of Health Promoting Lifestyle Profile II (Walker, Sechrist & Pender. 2002) was used as a tool for health promotion. As the measured score was higher, the health promoting activity was indicated to be higher. The results of this study were as follows: 1. As a result of checking the breast self examination compliance frequency between the experiment group that received the breast self examination participant education and the comparative group that did not receive the education, there was a significant difference in interaction between groups by time, as time passed by. 2. As a result of checking the breast self examination compliance capability between the experiment group and the comparative group, there was a significant difference in interaction between groups by time, as time passed by. 3. As a result of carrying out a repetitive measurement analysis, between the experiment group that received the breast self examination education and the comparative group that did not receive the education, which was carried out to validate the hypothesis that the former would have higher health promoting activities than the latter, there was no significant difference after the breast self examination education was conducted.

고래회충유충증은 해산어류에 기생하는 고래회충과(family Anisakidae)에 속하는 선충류 유충에 의한 질병으로 유충의 직접적인 위장관내 침입으로 인한 병변과 더불어 유충의 분비 배설물에 의한 알레르기 질환도 유발될 수 있다. 고래회충유충증은 A. simplex를 비롯하여 Contracaecum, Pseudoterranova, Hysterothylacium 등의 유충에 의해 야기될 수 있으나 이들에 대한 형태학적 감별 진단은 유충의 형태적 유사성으로 인하여 매우 어려운 경우가 많다. 이러한 형태학적 진단의 어려움을 극복하고 분자생물학적 감별진단 방법을 확립하기 위하여 A. simplex, Contracaecum type A. type C' 및 Goezia 유충을 숭어, 도다리, 고등어, 아나고, 참돔 등 5종의 어류에서 분리하였다. 각각의 유충으로부터 분리한 18S rDNA를 PCR로 증폭한 후 Taq 1, Hinf I, Hha I, Alu 1, Dde I, Hae III, Sau 96I, Sau 3AI 등 8종의 제한효소를 사용하여 PCR-RFLP를 시행하였다. PCR product의 크기는 약 2.0 Kb였으며 Hinf l, Alu 1, Hha I, Dde 1 및 Hae III로 A. simplex와 Contracaecum type C'을 구분할 수 있었다. 그러나 Contracaecum type A의 경우에는 Taq I, Hinf I, Alu I 및 Dde I의 경우에는 2가지 패턴으로 나타났으며 이들 가운데 일부는 A. simplex, Contracaecum type C', 및 Goezia와 동일한 분석 패턴을 보이기도 하였다. Goezia는 사용한 8개의 제한 효소 모두에서 A. simplex 및 Contracaecum type A 및 type C'과 각기 다른 양상을 보였다. 이러한 결과로 18S rDNA PCR-RFLP 방법은 A. simplex와 Contracaecum type C'의 감별 진단에 유용한 것으로 밝혀졌으며, Contracaecum type A의 분류에는 제한적으로 사용되어야 함은 물론 형태학적 분류 기준에 대한 재검토가 뒤따라야 할 것으로 사료되었다.

본 연구에서는 Keyhole limpet hemocyanin (KLH)에 대한 체액성 및 세포성 면역반응 유도에 대한 PAMAM dendrimer G4 (PAMAM)의 증강 효과를 조사하였다. PAMAM을 KLH와 2주 간격으로 2회 피하주사로 면역한 후, KLH에 대한 특이항체를 측정한 결과, KLH+PAMAM 면역 그룹은 KLH만을 단독으로 면역한 그룹에 약 30배이상 높은 유의한 항체가(IgG+IgA+IgM) 상승을 나타냈다. ELISA 분석에 의해 KLH 특이적인 면역글로부린의 isotype을 측정한 결과, PAMAM를 혼합하여 면역함으로서 IgG1, IgG2a, IgG2b, IgG3 및 IgM 항체의 역가가 유의하게 증가하는 것으로 확인되었다. 또한 면역 개시 7주째에 면역동물에 KLH 항원을 피하주사하고 swelling reaction을 통해 세포성 면역반응인 지연형 과민반응(DTH)을 측정한 결과, KLH+PAMAM으로 면역한 그룹에서 KLH만을 단독으로 면역한 그룹에 비해 높은 DTH 유도활성이 관찰되었다. 한편 면역동물의 비장세포를 취하여 in vitro에서 KLH로 재자극한 후 림프구 증식반응과 사이토카인 유도활성을 측정한 결과, PAMAM을 혼합하여 면역한 그룹에서 KLH 단독 면역 그룹에 비해 림프구의 증식반응에 유의하게 증가하였으며, Th1 type (IFN-γ)과 Th2 type (IL-4) 사이토카인의 생성도 모두 상승하는 것으로 확인되었다. 이상의 결과로부터 PAMAM dendrimer는 함께 투여된 항원물질에 의해 유도되는 세포성 면역과 체액성 면역을 상승시키는 활성이 있는 것으로 확인되었으며, 이는 PAMAM dendrimer가 면역 adjuvant로서 응용 가능한 소재임을 입증하는 것이다.

This paper empirically examines factors that potentially influence the success of a Web-based semantic search engine. A research model has been proposed that shows the impact of quality-related factors upon the effectiveness of a semantic search engine, based on DeLone and McLean's(2003) information systems success model. An empirical study has been conducted to test hypotheses formulated around the research model, and statistical methods were applied to analyze gathered data and draw conclusions. Implications for academics and practitioners are offered based on the findings of the study. The proposed model includes three quality dimensions of a Web-based semantic search engine-namely, information quality, system quality and service quality. These three dimensions each have measures designed to collectively assess the respective dimension. The model is intended to examine the relationship between measures of these quality dimensions and measures of two dependent constructs, including individuals' net benefit and user satisfaction. Individuals' net benefit was measured by the extent to which the user's information needs were adequately met, whereas user satisfaction was measured by a combination of the perceived satisfaction with search results and the perceived satisfaction with the overall system. A total of 23 hypotheses have been formulated around the model, and a questionnaire survey has been conducted using a functional semantic search website created by KT and Hakia, so as to collect data to validate the model. Copies of a questionnaire form were handed out in person to 160 research associates and employees working in the area of designing and developing semantic search engines. Those who received the form, 148 respondents returned valid responses. The survey form asked respondents to use the given website to answer questions concerning the system. The results of the empirical study have indicated that, of the three quality dimensions, information quality was found to have the strongest association with the effectiveness of a Web-based semantic search engine. This finding is consistent with the observation in the literature that the aspects of the information quality should serve as a basis for evaluating the search outcomes from a semantic search engine. Measures under the information quality dimension that have a positive effect on informational gratification and user satisfaction were found to be recall and currency. Under the system quality dimension, response time and interactivity, were positively related to informational gratification. On the other hand, only one measure under the service quality dimension, reliability was found to have a positive relationship with user satisfaction. The results were based on the seven hypotheses that have been accepted. One may wonder why 15 out of the 23 hypotheses have been rejected and question the theoretical soundness of the model. However, the correlations between independent variables and dependent variables came out to be fairly high. This suggests that the structural equation model yielded results inconsistent with those of coefficient analysis, because the structural equation model intends to examine the relationship among independent variables as well as the relationship between independent variables and dependent variables. The findings offer some useful implications for owners of a semantic search engine, as far as the design and maintenance of the website is concerned. First, the system should be designed to respond to the user's query as fast as possible. Also it should be designed to support the search process by recommending, revising, and choosing a search query, so as to maximize users' interactions with the system. Second, the system should present search results with maximum recall and currency to effectively meet the users' expectations. Third, it should be capable of providing online services in a reliable and trustworthy manner. Finally, effective increase in user satisfaction requires the improvement of quality factors associated with a semantic search engine, which would in turn help increase the informational gratification for users. The proposed model can serve as a useful framework for measuring the success of a Web-based semantic search engine. Applying the search engine success framework to the measurement of search engine effectiveness has the potential to provide an outline of what areas of a semantic search engine needs improvement, in order to better meet information needs of users. Further research will be needed to make this idea a reality.

정도관리(Quality Control)는 오차를 최소한으로 하여 검사의 신뢰도를 증진 시키는 것을 목적으로 하고 있으며 이러한 정도관리 활동을 통해 환자의 진단과 치료방침에 영향을 주는 핵의학 혈액 검사의 신뢰도가 확보되고 있다. 이에 연구자들은 신뢰도 향상의 추가적인 기법으로 건강검진 수검자를 대상으로 시행한 핵의학 혈액검사의 모집단 분포를 이용한 통계적 품질관리의 유용성을 평가해 보고자 한다. 2014년 1월부터 2014년 12월까지 서울아산병원 건강증진센터를 이용한 건강검진 수검자 41,341명을 대상으로 핵의학 혈액 검사 12종목에 대해 통계 분석을 시행 하였다. 통계분석은 핵의학 혈액 검사 12종목에 대한 결과 보고 치를 참고치 이내, 참고치 이상, 참고치 이하의 세 가지 그룹의 월간 백분율로 구분하여 모집단 분포의 평균값과 표준편차, 그리고 표준편차 지수(Standard Deviation Index: SDI)를 산출 하였고 그 결과 모집단 분포의 표준편차는 모든 그룹에서 대부분 ${\pm}2SD$ 이내의 결과를 보였다. 건강검진 수검자에 대한 핵의학 혈액검사 12종목(AFP, CEA, CA19-9, CA125, PSA, TSH, FT4, Anti-Tg-Ab, Anti-TPO-Ab, Calcitonin, 25-OH-VitD3, Insulin)의 모집단 분포를 분석한 결과 월간 백분율의 표준편차 지수(SDI)가 ${\pm}2.0$ 이상인 경우는, 1월과 3월 Insulin검사에서 각각 2.3, 2.4, 5월 Anti-Tg-Ab검사에서 2.2, 그리고 9월 CA19-9에서 2.2의 결과를 보였다. 이는 검사 Kit 시약의 이상 (동위원소 시약의 최대 결합률 저하), 검사반응 시간의 저하가 원인 이었다. 연구대상이 되는 전체의 속성을 포함하고 모집단 분포의 특성을 이용한 통계적 품질관리는 검사실에서 시행하고 있는 내부정도관리 프로그램을 보완하는 역할을 할 수 있으리라 생각된다.

Objective: To investigate the association of FSH receptor (FSHR) polymorphism at position 680 with outcomes of controlled ovarian hyper-stimulation for IVF-ET in Korean women. Design: Genetic polymorphism analysis. Materials and Methods: The FSHR polymorphism was analyzed by PCR-RFLP in 172 ovulatory women below the age of 40 year. Patients with polycystic ovary syndrome, endometriosis, or previous history of ovarian surgery were excluded. Results: Genotype distribution was 41.9% for the Asn/Asn, 47.7% for the Asn/Ser, and 10.5% for the Ser/Ser FSHR genotype group. There was no difference in age of subjects and infertility diagnosis between genotype groups. When the patients were grouped according to their FSHR genotype, the basal levels of FSH (day 3) were significantly different among the three groups ($6.0{\pm}0.3\;IU/L$ (mean $\pm$ SEM), $5.8{\pm}0.3\;IU/L$, and $8.6{\pm}1.2\;IU/L$ for the Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively, p=0.002). The Ser/Ser group showed a higher total doses of gonadotropins required to achieve ovulation induction, and a lower serum estradiol levels at the time of hCG administration compared with other two groups, but the differences were of no statistical significance. The numbers of oocytes retrieved were significantly different among the three groups ($8.6{\pm}0.8$, $9.9{\pm}0.6$, and $6.3{\pm}0.9$, for the Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively, p=0.049). Clinical pregnancy rates were 42.4%, 25.9%, and 29.4% for the Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively. Conclusion: Homozygous Ser/Ser genotype of FSHR polymorphism at position 680 was associated with decreased ovarian response to gonadotropin stimulation for IVF-ET.

본 연구는 일개 보건지소에 등록된 고혈압 환자의 치료율 및 관리율을 구하고 치료지속성과 관련성이 있는 변수를 파악하고 치료중단 이유를 조사하기 위하여 2000년 11월 이전에 군남면 보건지소에 등록되어 치료받고 있는 고혈압 환자 295명을 대상으로 하여, 의무기록조사와 전화설문조사를 병행하여 실시되었다. 그 결과는 다음과 같다. 1. 대상자 295명중 남자가 108명(36.6%), 여자가 187명 (62.7%)이었으며 평균연령은 남자 64.6세, 여자 66.3 세로 여성에서 더 높았다(p<0.05). 2. 대상자의 54.9%가 지속적인 치료를 받는 것으로 조사되었고, 간헐적 치료군이 19.3%, 치료중단군이 25.8%였다. 3. 성, 연령, 의료보장, 거주지 등 연구대상자의 특성중 거주지로부터 보건지소까지 이동시 소요되는 시간만이 치료지속성과 통계적으로 유의한 관련성이 있었다(p<0.01). 3. 치료중단의 이유로는 증상 또는 몸의 불편함이 없어서가 23.9%를 차지하였고 그 다음으로 타의료기관 이용(18.4%), 교통의 불편(17.9%), 약국 이용(14.9%), 거동 불가능(7.5%), 경제적인 이유(6.0%), 보건지소 서비스에 불만족(4.4%) 순이었다. 4. 전체 대상자 295명의 평균 치료혈압은 $144.9{\pm}12.9/86.9{\pm}8.6mmHg$이었고, 이들 중 평균 치료혈압 이 140/90mmHg 미만으로 적절히 조절되는 환자는 32.5%였다. 이러한 연구결과를 종합해 볼 때, 보건지소 고혈압 환자들의 낮은 치료율, 관리율을 개선하기 위해서는, 적극적인 추후관리와 고혈압에 대한 환자의 잘못된 인식을 교정해주는 효과적인 보건교육을 포함하는 보다 체계적인 고혈압 관리 사업이 요구된다고 하겠다.
