모바일 환경에서 브로드캐스트는 그 확장성 때문에 매우 유용한 데이터 전송 방법이다. 'push-based' 데이터 전송 방식에서 서버는 넓은 대역폭을 통해 클라이언트에게 다양한 데이터를 반복적으로 브로드캐스트 한다. 〔1,2〕 브로드캐스트에 기반을 둔 정보 시스템의 데이터간의 연관성에 관한 연구는 미흡한 실정이다. 상호 연관 데이터의 브로드캐스트에서, 클라이언트는 자연스럽게 상호 연관된 데이터의 집합을 요청하게 되며, 데이터의 상호 연관성을 고려할 때 기존의 스케줄링 및 캐싱 기법 등은 달라져야 한다. CBS〔3〕에서는 모든 데이터간의 연관도를 계산하여 최소 비용 경로를 구해, 이 순서대로 브로드캐스트하는 기법을 제안하였다. CBS 기법은, 클라이언트가 연관된 데이터를 동시에 요청하지 않고, NP-문제인 최소 비용 경로를 많은 데이터에 대해서 실시간에 계산해야 되며, 데이터 아이템간의 상호 연관성이 클라이언트마다 다르게 정의되는 문제점이 있다. 따라서 본 논문에서는 응답 시간을 줄이기 위해, 브로드캐스트 되는 상호 연관 데이터의 prefetching기법을 제안한다, 제안된 CT 기법은 상호 연관도와 브로드캐스트 대기시간을 고려하여 캐시를 관리한다. CT를 현실적으로 적용한 ACT의 알고리즘을 소개하였으며, 시뮬레이션을 통해 CT의 성능과 특징을 실험하였다.

Purpose : The aim of this study was to investigate patterns of medical use among juveniles and adolescents, including for chronic disease, in Korea. The study sought to do the following: (a) investigate the extent to which chronic diseases account for medical expenditures, (b) investigate and the socio-demographic characteristics associated with medical use, and (c) identify the differences in medical use between juveniles and adolescents. Methods : We used data from the 2015 Korean Health Panel and selected 12 variables. The socio-demographic characteristics investigated included, growth period (juvenile, adolescents), gender, family income, national basic livelihood act status, disability registration, and degree of disability. There were five medical factors that were considered: emergency room use, hospitalization use, hospital outpatient use, chronic disease, and medical expenditure. Data were analyzed using stepwise multiple and logistic regression. Results : The prevalence of chronic disability in juveniles and adolescents was 31.1 % and 1 %, respectively. The factors affecting medical expenditures included hospitalization use, hospital outpatient use, family income, disability, gender, chronic disease, and emergency room use ($R^2=.160$, p<.05). For national basic livelihood act recipients, the probability of having chronic disease was about 1.6 times higher (OR=1.597, 95 % CI=1.092-2.335, p=.016), compared with non-national basic livelihood act recipients. People with disabilities were 6.6 times more likely than those without disabilities to suffer from chronic disease (OR =6.571, 95 % CI=2.776-15.556, p<.001). Hospital outpatient user was 2.3 times higher than non-user (OR=2.260, 95 % CI=1.702-3.001, p<.001). Juveniles had a 1.7 times and 6.2 times higher likelihood of emergency rooms user (OR=1.654, 95 % CI=1.270-2.155, p<.001), and hospital outpatient user than adolescents (OR=6.208, 95 % CI=4.443-8.676, p<.001). Conclusion : The findings of this study suggest that health care services for juveniles is needed to manage chronic diseases that have an effect on medical expenditures.

I have practiced this reserch for the purpose of proposition of basic data for amendment and addition of computer system after I surveyed the degree of abilities and satisfaction on the computerization in nursing\ practice. Subjects were collected from September 1 to September 30, 1998. Study subjects are 151 clinical nurses who are working at university hospital in Chonbuk area. Study instrument consists of 116 questionnaire which was developed by Kim H. K(1998). The data were analized number, mean ,t-test, ANOVA by using SPSS. The study results are as follows: 1. Most of the nurses who answered the questions were educated computerizing(96%). The abilities of computer program utilities were the most in inputting data(74%). The program nurses wanted computerizing education was wordprocess, dealing internet and statistics. 2. As for applying parts of computer system in nursing, the most nurses were Dr's order check (96%), treatment activity(91.4%), medication(89.4%), lab. test(87 .4%), transfering department(85.4%), transfering room(79.5%), diet(71.8%), discharge (70.2%), Barcord Sticker(70.2%) , reservation(62.2%) in order that were all conected order system mutually to other part. It showed that computer system was not applied for treating the original nursing work such as nursing record (13%), duty scheduling(6.0%) , nursing process(4.6%) , Q.I(1.3%), nursing research(1.3%), education(1.3%), 3. As for the benefit when computer system is applied for, the most respondence was promptness of work and convenience(90.6%) , exactness of work (82.8%), offering information exactily and efficiently(36.3%), offering good quality of nursing (6.0%) in order. 4. The degree of contentment on computerizing in nursing practice showed average 3.24%. The best marking item is that they are eager to participate in the computer education. Next, the automatic output of label and giving the number automatically is to prevent loss and mentioned items of patient registration from being changed(3.95) and to prevent mistakes possibly happening because of doctor's difficult order(3.85). 5. The problems which may happen to in nurses' utilization of computerization for the nursing practice showed average 3.18. The most problem is that the practice may stop because of the problem of computer itself(3.67), and the next, the indication of act can be imperfect(3.66) , manual training may overlap because of incomplete computerization (3.60), practical education for the computerizing is lack(3.41), and the computer literate nurses are lack(3.40) . 6. Study subject's contentment by age was significant difference(F=3.10,P=0.0119). Study subject's contentment by job posision was significant difference(F=6.001P=0.0034) I will propose the following according to the above results. The domain of original nursing practice is urgernt. Manual and indication of act should be made before long in computer obstacle. Nursing department should support the nurses so that they could receive the education needed for the nurses themselves.

It is important to measure the rotational accuracy of NC lathe spindle as it affects to the qualities of all machines machined by the NC lathe using in industries. The bad rotational accuracy of NC lathe spindle are caused mainly by wearness of the spindle in using and quality of spindle when machining and using low level bearings. It occurs especially in case of NC lathes because the cutting force acting to work-piece act on one side to the spindle not to both sides symmetrically. Therefore in this study, constructing experimental appratus for measuring of rotational accuracy by using eddy current type gap sensors, converters, screw terminal, data acquisition board inserted in computer and software f3r data acquisition, DT VEE ver. 5.0 and then error data acquired in the rotational accuracy test of NC lathe spindle are analysed in plots and statistical treatments.

Background: It has been proven that an individuals health behavior is determined through a series of processes. This study aimed to assess the stages of adoption of breast cancer screening, and to identify the factors relating to progress through these stages. Materials and Methods: There were 202 female participants aged 20-59 years who were living in Chungbuk, South Korea. They were informed of the study purpose and agreed to participate. Data were collected from October 2010 to January 2011 by assessing the breast cancer screening stage, health beliefs, socio-demographic factors, and other facilitating factors. The participant current stage of adoption of breast cancer screening was classified using the Precaution Adoption Process Model (PAPM), and the various PAPM stages were compared with each other to identify factors likely to determine progress between stages. The data were analyzed using the ${\chi}^2$-test, ANOVA, Duncan test, and multiple logistic regression. Results: Approximately half of all participants were not on-schedule for breast self-examination and mammography (unaware, 9.4% and 11.4%, unengaged, 8.4% and 5.0%, undecided, 20.3% and 17.8%, decided not to act, 1.5% and 1.0%, decided to act, 13.4% and 15.3%, respectively). The factors likely to determine the progress from one stage to another were age, marital status, exposure to media information about breast cancer, self-efficacy, and perceived severity. Conclusions: These results suggest that it is necessary to develop a tailored message for breast cancer screening behavior.

이 연구는 미국 연방통신품위법 230조의 개정 논의를 신제도주의의 관점에서 분석하였다. 지금까지 내구력을 유지하며 미국 인터넷 내용규제의 기본틀을 구성해왔던 연방통신품위법 230조의 면책 조항은 오늘날 중대한 전환에 직면해 있다. 이 조항을 개폐하려는 정치적 시도들이 초당적인 협력으로 진행되고 있기 때문이다. 역사적 제도주의의 관점으로 연방통신품위법 230조의 개폐 논의를 분석한 결과, 미국 인터넷 내용규제 레짐의 변동은 가짜뉴스나 개인 정보 유출과 같은 외생적 사건과 함께, 행위자 간의 경쟁과 갈등이라는 내생적 요인이 복합적으로 작용해 발생한 것으로 여겨진다. 이상의 분석은 한국의 인터넷 내용규제 거버넌스의 제도개선과 방향성에 대해서도 함의를 지닐 수 있다.

The Public Data Act mandates that every public institution must make efforts to facilitate convenient access to public data for all and take necessary measures to universally expand the right to use such data. Furthermore, it specifies that the head of a public institution must provide the data held and managed by that institution to the citizens. The Construction Project Information Disclosure Service aims to increase the utilization of data within the Construction CALS System, creating new added value by disclosing information and fostering communication. This service seeks to enhance public interest and transparency, support the creation of new businesses based on construction project data, and stimulate related industries. Since 2019, a total of 26 types of information have been disclosed through this service. As the volume of disclosed information continues to increase, there has been a consistent demand for reducing burden on data providers and enhancing user functionality. This study analyzes the current status of the Construction CALS Information Disclosure System to identify its existing challenges. Subsequently, it establishes a systematic approach to the data opening process and proposes enhancements to information disclosure and search functionalities for addressing these challenges.
