  • 구조물의 건전성 모니터링은 구조물의 안전 및 사용성을 위하여 중요하다. 구조물의 변위는 직접적인 구조물 강성의 평가 지표가 되기 때문에 정확하고 주기적으로 모니터 되어야 한다. 그러나 이러한 변위 모니터를 위한 실용적인 방법이 아직까진 없고, 특히 고층 건물이나 장 스팬 교량과 같이 접근성이 어려운 구조물의 경우는 더욱 그러하다. 이러한 문제점을 해결하기 위하여 레이저 펄스를 이용하여 원격으로 물체 표면을 탐사하고 수많은 좌표를 생성할 수 있는 라이다 시스템을 제안하였다. 본 연구에서는 지상 라이다를 이용하여 구조물의 헬스 모니터링을 위한 새로운 변위계측모델을 개발하였고 검증을 위한 실험이 수행되었다.

  • This paper classifies the success factors of collaboration system in the shipbuilding industry. We propose the structural model that identifies the relationship between the success factors and organizational performance. To test empirically the relationship between the factors, we developed the measurement of each factors. This paper has examined the relationship between the independent variables and the mediating variables, also has examined the relationship between the parameters and a final dependent variable. The independent variables are as follows, (1) quality of system including reliability, flexibility, and accessibility, (2) the quality of information including contents, expressiveness, and (3) the partner relationship including the information sharing and the compatibility of strategies. The mediating variables are user involvement, parter trust, and user satisfaction. The final dependent variable is business performance. The hypotheses test proved that the system quality significantly affect user satisfaction, the information quality positively influence on the user participation, and the information sharing and strategic fit of partner relationship positively affect partner trust. Also, the user participation and partner trust significantly affect user satisfaction. Finally, the user participation, user satisfaction, and partner trust have a decisive effect on the organizational performance. The results of hypothesis test verified that the quality of information and system, also partner relationship are important to operate successfully the collaboration system in the shipbuilding industry. Also, the mediating variables are important to explain the structural relationship between the independent variables and organizational performance.

  • Background Postoperative pain is one of the most common concerns of patients undergoing hair transplantation surgery. Because most patients are satisfied with the cosmetic improvement after transplantation, amelioration of postoperative pain would help to increase patient accessibility to hair restorative surgery and greatly impact patient satisfaction with the final cosmetic results. This study was performed to investigate postoperative pain after hair transplantation. Methods In total, 241 patients (202 who underwent follicular unit transplantation [FUT] and 39 who underwent follicular unit extraction [FUE]) were eligible for the study. Postoperative pain was evaluated on postoperative days 1, 2, 3, 4, 5, and 7 using the Wong-Baker Faces Pain Scale. The patients' medical records were retrospectively reviewed for information on the harvesting method, number of transplanted grafts, size of donor design, and laxity, elasticity, and glidability of the scalp in relation to postoperative pain. Results Postoperative pain after hair transplantation, assessed with the Wong-Baker Faces Pain Scale, seemed to provide very subjective results. None of the variables were correlated with postoperative pain in the FUT group. Such pain, however, tended to disappear by postoperative day 3. Patients in the FUE group experienced significantly less severe pain than those in the FUT group. Conclusions Postoperative pain was significantly less severe in patients whose donor hair was harvested by the FUE than FUT method. Postoperative pain had almost disappeared by postoperative day 3 in the FUT group, whereas only minimal pain was present even on postoperative day 1 in the FUE group.

  • This study aims to propose a framework for evaluating the impact of artificial intelligence (AI) services, based on the concept of AI service impact. It also suggests a model for evaluating this impact and identifies relevant factors and measurement approaches for each item of the model. The study classifies the impact of AI services into five categories: ethics, safety and reliability, compliance, user rights, and environmental friendliness. It discusses these five categories from a broad perspective and provides 21 detailed factors for evaluating each category. In terms of ethics, the study introduces three additional factors-accessibility, openness, and fairness-to the ten items initially developed by KISDI. In the safety and reliability category, the study excludes factors such as dependability, policy, compliance, and awareness improvement as they can be better addressed from a technical perspective. The compliance category includes factors such as human rights protection, privacy protection, non-infringement, publicness, accountability, safety, transparency, policy compliance, and explainability.For the user rights category, the study excludes factors such as publicness, data management, policy compliance, awareness improvement, recoverability, openness, and accuracy. The environmental friendliness category encompasses diversity, publicness, dependability, transparency, awareness improvement, recoverability, and openness.This study lays the foundation for further related research and contributes to the establishment of relevant policies by establishing a model for evaluating the impact of AI services. Future research is required to assess the validity of the developed indicators and provide specific evaluation items for practical use, based on expert evaluations.

  • The purpose of this study was to develop a basic framework and criteria for evaluation of quality care provided to patients with the attributes of disease in the home care nursing field, and to provide measurement tools for home health care in the future. The study design was a developmental study for evaluation of hospital-based HCN(home care nursing) in Korea. The study process was as follows: a home care nursing study team of College of Nursing. Yonsei University reviewed the nursing records of 47 patients who were enrolled at Yonsei University Medical Center Home Care Center in March, 1995. Twenty-five patients were insured at that time, were selected from 47 patients receiving home care service for study feasibility with six disease groups; Caesarean Section (C/S), simple nephrectomy, Liver cirrhosis(LC), chronic obstructive pulmonary disease(COPD), Lung cancer or cerebrovascular accident(CVA). In this study, the following items were selected : First step : Preliminary study 1. Criteria and items were selected on the basis of related literature on each disease area. 2. Items were identified by home care nurses. 3. A physician in charge reviewed the criteria and content of selected items. 4. Items were revised through preliminary study offered to both HCN patients and discharged patients from the home care center. Second step : Pretest 1. To verify the content of the items, a pretest was conducted with 18 patients of which there were three patients in each of the six selected disease groups. Third step : Test of reliability and validity of tools 1. Using the collected data from 25 patients with either cis, Simple nephrectomy, LC, COPD, Lung cancer, or CVA. the final items were revised through a panel discussion among experts in medical care who were researchers, doctors, or nurses. 2. Reliability and validity of the completed tool were verified with both inpatients and HCN patients in each of field for researches. The study results are as follows: 1. Standard for discharge with HCN referral The referral standard for home care, which included criteria for discharge with HCN referral and criteria leaving the hospital were established. These were developed through content analysis from the results of an open-ended questionnaire to related doctors concerning characteristic for discharge with HCN referral for each of the disease groups. The final criteria was decided by discussion among the researchers. 2. Instrument for measurement of health statusPatient health status was measured pre and post home care by direct observation and interview with an open-ended questionnaire which consisted of 61 items based on Gorden's nursing diagnosis classification. These included seven items on health knowledge and health management, eight items on nutrition and metabolism, three items on elimination, five items on activity and exercise, seven items on perception and cognition, three items on sleep and rest, three items on self-perception, three items on role and interpersonal relations, five items on sexuality and reproduction, five items on coping and stress, four items on value and religion, three items on family. and three items on facilities and environment. 3. Instrument for measurement of self-care The instrument for self-care measurement was classified with scales according to the attributes of the disease. Each scale measured understanding level and practice level by a Yes or No scale. Understanding level was measured by interview but practice level was measured by both observation and interview. Items for self-care measurement included 14 for patients with a CVA, five for women who had a cis, ten for patients with lung cancer, 12 for patients with COPD, five for patients with a simple nephrectomy, and 11 for patients with LC. 4. Record for follow-up management This included (1) OPD visit sheet, (2) ER visit form, (3) complications problem form, (4) readmission sheet. and (5) visit note for others medical centers which included visit date, reason for visit, patient name, caregivers, sex, age, time and cost required for visit, and traffic expenses, that is, there were open-end items that investigated OPD visits, emergency room visits, the problem and solution of complications, readmissions and visits to other medical institution to measure health problems and expenditures during the follow up period. 5. Instrument to measure patients satisfaction The satisfaction measurement instrument by Reisseer(1975) was referred to for the development of a tool to measure patient home care satisfaction. The instrument was an open-ended questionnaire which consisted of 11 domains; treatment, nursing care, information, time consumption, accessibility, rapidity, treatment skill, service relevance, attitude, satisfaction factors, dissatisfaction factors, overall satisfaction about nursing care, and others. In conclusion, Five evaluation instruments were developed for home care nursing. These were (1)standard for discharge with HCN referral. (2)instrument for measurement of health status, (3)instrument for measurement of self-care. (4)record for follow-up management, and (5)instrument to measure patient satisfaction. Also, the five instruments can be used to evaluate the effectiveness of the service to assure quality. Further research is needed to increase the reliability and validity of instrument through a community-based HCN evaluation.

  • 저탄소 녹색성장 패러다임에 맞춰 지하철은 대중교통 활성화를 위한 도시 교통의 핵심 운송 수단이다. 지하철은 대량 수송 교통체증완화 교통사고 감소 등의 역할 뿐 아니라 노선 확장에 따라 도시 공간과 네트워크상의 승객 수요의 변화를 촉진시킨다. 현재 수요예측을 주축으로 노선계획이 이루어지고 있어, 지하철 노선 변화에 따른 교통 접근성과 승객 수요 변화를 위한 실증적인 연구가 미비하다. 이에 본 연구의 목적은 공간구문론을 이용한 사전사후 분석을 통해 지하철 개통에 따른 대중교통 영향성을 네트워크의 연결성, 승객 이동성 측면에서 정량적으로 예측 할 수 있는 대안적 평가 방법론을 제시하는 것이다. 우선 2009년 개통된 서울시 지하철 9호 선을 중심으로 도시 철도 네트워크를 구축하고, 공간 구문 모델을 통해 9호선이 개통됨에 따른 네트워크의 위상적 변화 패턴을 분석하였다. 또한, 모델 측정 결과를 검증하기위해, 서울시 교통 카드시스템의 역간 지하철 승차 인원수와 버스 노선별 승차 인원수 자료를 이용하여, 경쟁 노선을 대상으로 버스 이용객의 수단 전환과 주요 환승역에서 승객 수요 변화를 분석하였다. 결론적으로 본 연구 방법론을 통해 지하철 노선 계획에 있어 승객수요변화를 가시화하고 노선 추가에 따른 전후 시공간적 변화 분석이 가능하였으며 향후 주변 대중교통의 영향성과 실제 대중교통 이용자의 이동패턴에 대한 효과적인 공간적 변화 분석에 활용될 것으로 기대한다.

  • Periodontal defects of the furcation are characterized by several inherent anatomic factors that can make successful periodontal therapy difficult and results unpredictable. The severity and rate of occurrence of periodontal disease are directly related to the location of the furcation relative to the cementa-enamel junction and anatomical form of the root by limiting the accessibility and effectiveness of the periodontal instrumentation. This study investigated the reliability and accuracy of panoramic radiograph diagnoses of the periodontal state of mandibular molars, particularly regarding the diagnosis of furcation area periodontal defects, treatment planning, and prognosis prediction. This study examined a total of 110 teeth belonging to 33 subjects (19 male, 14 female) presenting with incipient to moderate periodontitis 4-7mmpocket depth. The alveolar bone level, length and width of the root trunk, and root separation angle were measured using the panoramic radiograph and compared to the results taken directly by retracting a full-thickness flap. The results of the study are as follows: 1. Data regarding the alveolar bone level of the mandibular first molar showed that the directly taken surgical measurements resulted in $5.1{\pm}0.9mm$ that was slightly deeper than the corresponding panoramic measurement resulted in $4.8{\pm}0.8mm$, but these differences were statistically insignificant (p>0.05). 2. The data of the directly taken surgical measurement of the mandibular second molar $(5.1{\pm}1.1mm)$ was slightly deeper than the corresponding panoramic measurement $(4.7{\pm}1.2mm)$, but these differences were statistically insignificant (p>0.05). 3. The measured values of the length and width of the mandibular first molar root trunks were determined to be $4.1{\pm}0.6mm$ and $7.3{\pm}0.9mm$, respectively, while the values of the mandibular second molar root trunks were determined to be $4.6{\pm}1.3mm$ and $7.6{\pm}0.9mm$ respectively. The differences between these values were found to be statistically significant (p<0.01). 4. The measured values of the root separation angle showed that the mandibular first molars averaged $34.5{\pm}4.4^{\circ}$, while the mandibular second molars averaged $23.0{\pm}10.0^{\circ}$. The differences between these values were found to be statistically significant (p<0.01).

  • 본 연구에서는 토지적성평가 평가결과의 정확성을 향상시킬 수 있는 방안을 제시하였다. 이를 위해 지표값 측정 및 임계치 설정을 중심으로 현 제도에서 적용하고 있는 평가방법과 이를 개선할 수 있는 방안을 검토하고, 사례지역을 대상으로 두 가지 방법을 적용함으로써 기존의 방법에 비해 지니는 효과를 파악하였다. 구체적인 분석과정은 1) 공간적 입지특성에 대한 거리측정시 저항을 고려한 분석, 2) 보전적성값 산정시 물리적 특성지표에 적용되는 귀속도 함수의 임계치 설정에 따른 평가결과를 측정하였다. 평가결과 첫째, 저항을 고려한 측정방법이 단순한 직선거리에 의한 방법에 비해 하천이나 임야 등 접근성이 떨어지는 지역적 특성을 보다 잘 반영하고 있는 것으로 나타났다. 둘째, 대상지역의 최고값을 최대임계치로 설정하는 현재의 방법이 지표의 측정값 분포를 고려한 임계치 설정 때보다 상대적으로 평가절하된 점수값을 도출할 수 있음을 예측할 수 있었다. 마지막으로 인공위성영상자료를 평가결과에 중첩시켜 보았을 때 본 연구의 방법에 의한 적성등급이 현황과 보다 잘 부합하는 것으로 나타났다. 본 연구에서 제시한 평가방법은 토지적성평가 결과의 정확성을 향상시켜 준다는 점에서 의의가 크다. 더불어 그간 제도의 시행과정에서 나타난 문제점--평가단위의 문제, 평가절차상의 문제, 기초자료 정비의 문제 등--이 보완된다면 국토 및 도시정책 수립시 이를 효과적으로 지원할 수 있는 공간의사결정지원체계(SDSS)로서도 활용될 수 있을 것이다.

  • This study is an empirical investigation and study on the measurement of nursing service quality as perceived by patients. A series of H1. H2. H3 alternative hypotheses were tested using a sample of 250 patients in Taegu City. Korea. HI hypothese were tested for application of five component of service quality (SERVQlTAL and SE RPERF : tangiblity. reliability. responsiveness. accessibility. understandability) in Taegu area Hospitals. Validity test - the five components of service quality were rearranged into two components of service quality (personal factor. nonpersonal factor). Although SERVQUAL was verified in USA. application for five components of service quality in Korea indicated that it need more analytical studies. Nobody can deny the fact that the recent growth of the nursing service quality is one of the most important driving forces of hospital management. In many hospitals. the nursing quality charges more than 50% of the medical service quality. As a result. many hospital managers should be enormous interests in the investment potentiality of the nursing service. However. doesn't many researchers invest their time and effort on the research of the quality control in nursing service. Nursing service management is the process to satisfy customer's desires and expectations through the various service activities. Presently nursing service are being faced with three Common tasks of improving quality of nursing service. competitively differential advantage and productivity because of quantitative expansion of Nursing service. Such a phenomenon is also found in our medical service industry. resulting from increasing demands for medical service owing to national medical insurance policy and consumer's attitude change emphasizing prevention of illness. excessiveness of medical facilities in large cities and increasing medical lawsuits due to influence of consumerism. Therefore. under such circumstances. this research on nursing service is conducted from nursing managements to improve the nursing service quality problems faced by medical institutions. The results of this theoretical/empirical research are as follows: 1. Nursing service Quality is regarded as patients' perceived quality and evaluated on the basis (5 dimension) of technical and functional quality. 2. Nursing service Quality is a concept of patients evaluation on the measurable multi-dimensions intrinsic and extrinsic attributes of service. 3. Nursing service Quality is conceptually defined as the difference between the perceived service and the expected service. 4. Korean consumers trend to evaluate nursing service quality based on such dimensions as responsiveness and reliability. understandability. accessibility. tangibility. 5. After analyzing whether or not there are some differences in respective medical institution. it was found that there are significant difference on understandability. reliability. communicability. courtesy. competence. 6. After analyzing the difference between the expected nursing service and the nursing perceived service, it was found that the expected nursing service is higher than the perceived service in every medical institution. 7. HI hypothesis was tested with regard to the validity test between SERVQUAL and SERVPERF in nursing service quality. The result of validity test between SERVQUAL and SERVPERF was found to have differential result. That is the R2 of SERVPERF is higher than that of SERVQUAL. Therefore. HI was verified in nursing management. H2. H3 hypotheses were tested whether or not the nursing service quality and patient satisfaction is the preceding variable. The result of H2 hypothes is that the nursing service quality is the preceding variable of patient satisfaction and the patient satisfaction is that of revisiting intention. After analyzing whether or not there is any differences on the demographic variable of five nursing service quality factor. it was found that there are statistically significant differences on communicability and courtesy at the sex. understand ability. accessibility and tangibility at the age. understandability at the academic background respectively.
