기록관의 온라인 서비스 향상을 위한 웹사이트 평가기준설계에 관한 연구

이윤주,Lee, Yoon-Ju 한국기록학회 2007 기록학연구 Vol.0 No.16

인터넷의 확산은 기록관의 서비스환경에 많은 변화를 가지고 왔다. 즉, 기록관의 웹사이트를 통하여 이용자에게 기록관에 대한 정보와 이용, 접근을 보다 편리하고 신속하게 서비스 할 수 있게 되었으며, 앞으로 그 비중이 더욱 증대하게 될 것이다. 이제 기록관 웹사이트는 기록관 안내나 마케팅의 도구 또는 단순히 인터넷 기반 자료에 대한 게이트웨이로서의 기능만 하는 곳이 아니라, 이용자에게 서비스에 대한 안내 및 지식을 제공할 뿐만 아니라 기록관 서비스에 직접 연결 할 수 있는 능력을 제공하는 기록관의 모든 서비스의 가상공간이라 할 수 있다. 현재 우리나라에 존재하고 있는 기록관들은 웹사이트 구축을 진행하고 있거나, 구축된 웹사이트를 발전시키고 있는 실정이다. 또한 이용자들의 웹 서비스의 이용도와 의존도 또한 높아지고 있다. 그러나 현재까지 웹사이트 평가에 관한 다양한 연구가 있었지만, 기록관의 웹사이트 평가에 관한 연구는 이루어지지 않고 있다. 다양한 계층의 이용자를 대상으로 정보서비스를 제공하는 기록관의 웹사이트는 이용자 중심의 편리성과 알권리, 정보제공을 중심으로 한 정보서비스 여부에 보다 많은 연구와 관심을 가질 필요성이 있으며, 기록관 웹사이트 구축의 질적 수준을 높일 수 있도록 웹사이트의 평가기준 또한 연구할 필요가 있다는 것은 두말할 나위가 없을 것이다. 따라서 기록관의 목적과 기능에 적합한 웹사이트 평가기준을 개발 및 제시하고, 국 내외기록관을 직접 평가해 봄으로써 취약점과 보완점을 지적하여, 기록관 웹사이트 구축 및 재개발을 위한 개선방안을 제시하였다. Archives provide users with easier and more convenient access to and use of archival data through their Internet websites. Now, archival websites function not only as a tool of information provision or marketing, or as a gateway of Internet-based materials, but also as cyber space for all services of archives, providing users with information and knowledge and direct accessibility to the services in the archives. At present, Korean archives are proceeding with establishing websites or upgrading existing websites, and the use rates and reliability of web services by users are becoming higher. However, although there have been various studies for the evaluation of general websites, few are found with regard to the evaluation of archival websites. It is necessary for archival websites that provide information service to users of every stripe to make more efforts and have more interest in user-centered convenience, right to know, and information provision-centered service. Accordingly, needless to say, it is necessary to study evaluation criteria of websites so that high quality archival websites can be established. With this background, this study establishes evaluation criteria for archival websites, which are appropriate to their objectives and functions and directly evaluates archives, presenting ways to establish and redevelop archival websites. More detailed purposes are as follows: First, analyzes existing theories of evaluation through reviews on previous literature and elicits evaluation criteria for websites, which are appropriate to archives; Second, based on the elicited evaluation criteria for archival websites, examines the current state of domestic archival websites through analytic evaluation; and Third, presents ways to improve archival websites that may be helpful in establishing or improving them in the future. The expectancy effects of this study are as follows: First, it will be helpful when one wishes to identify the current state of archival websites and to improve or redevelop existing websites, or to develop online service through website; Second, it will function as a checklist when a developer who is to establish an archival website wishes to develop evaluation criteria; and Third, it may be used as an inspection tool when an archives contracts out the establishment of its website.

Mushrooms are valued as a nutritional food and also as an important source of useful medicinal components. They produce various secondary metabolites which have interesting biological activities and unique chemical structures. As part of our ongoing investigation on chemical constituents and bioactive components of Korean native mushrooms, compound 1, an indole alkaloid, was isolated from the fruiting body of Boletus umbriniporus. B. umbriniporus is characterized by its yellow flesh, which changes to pallid blue when exposed to air, and its chemical constituent has not been reported. Chemical structure of compound 1 was determined to be flazin on the basis of ESI-mass, $^1H$ NMR, $^{13}C$ NMR, $^1H-^1H$ COSY, HMQC, and HMBC analysis. This compound was isolated from the fruiting body of B. umbriniporus for the first time. 우리나라 자생 버섯에 함유된 화학적 구성성분을 조사하던 중 암갈색그물버섯에서 indole alkaloid 화합물을 분리하고 mass 및 NMR 분석을 통하여 화학구조를 flazin으로 동정하였다. 비록 Flazin 화합물이 젖비단그물버섯에서 분리되어 보고된 적은 있으나 본 연구에 의하여 암갈색그물버섯에도 flazin 성분을 함유하고 있음이 처음으로 밝혀졌다.

ABR 형태의 데이터 서비스를 위한 무선 MAC:APRMA

이윤주,강상욱,여현,최승철,Lee, Yoon-Ju,Kang, Sang-Wook,Yoe, Hyun,Choi, Seung-Chul 한국통신학회 1997 韓國通信學會論文誌 Vol.22 No.10

본 논문에서는 PRMA의 구조를 사용하여 ABR 형태의 데이터 서비스를 수행 할 수 있는 알고리즘을 도입하므로서 그 개념을 확장하고, 채널의 이용효율을 극대화하도록 설계된 무선 MAC 알고리즘인 APRMA를 제안한다. 기존의 PRMA에서는 랜덤 데이터를 전송하고자 하는 단말들은 슬롯을 예약할 수 없다. 즉, 슬롯의 예약은 시간 지연에 엄격한 음성에만 국한된다. 그러나 데이터들도 요구하는 서비스 품질을 만족시켜 주어야 하며, 이를 위해 데이터에 대해서도 예약을 가능하게 하므로서 채널의 처리율도 높일 수 있다. 따라서 무선 MAC에서는 음성 뿐 아니라 데이터에 대해서도 예약이 수행되어야 한다. 이때, 데이터에 고정된 전송율을 갖도록 슬롯을 예약해줄 수도 있겠지만 이로 인해 시간 지연에 민감한 서비스들의 효율이 떨어질 수 있다. 따라서, APRMA에서는 초기에는 최소한의 대역만을 할당해주며, 잉여의 대역이 존재하면 계속 그 전송율을 높여나갈 수 있게 하므로서 채널의 이용율을 높이고, 음성과 같은 상대적으로 우선순위가 높은 서비스 요청에 대해서도 동시에 그 서비스 품질을 만족시킬 수 있다. In this paper, we propose a wireless MAC protocol named APRMA, which is capable of supporting the ABR type data service and maximizing channel utilization. In PRMA protocol, data terminals with random data packets cannot reserve slot. That is, slot reservation is applicable to the time constraint voice packet exclusively. But the reservation scheme has to be performed for loss sensitive data packet, and so data packets can get their quality of service. Therefore, in wireless MAC, reservation technique has to be used for both voice and data services. But in service aspects, if a fixed bandwidth is allocated to data terminals, time constraint voice packets may have a low efficiency. So in this study, the terminal which wants to request for ABR tyupe service, acquires a minimum bandwidth from system for thefirst time. If the system has extra available bandwidth, ABR terminals would acquire additional bandwidth slot by slot. As a result, APRMA protocol cansupporty the data service with loss sensitivity and maintain their channel utilization high. Also high priority services like voice can be satisfied with their QoS by APRMA.

Neural network is used in many fields of control systems, but input-output patterns of a control system are not easy to be obtained and by using as single feedback neural network controller. And also it is difficult to get a satisfied performance when the changes of rapid load and disturbance are applied. To resolve those problems, this paper proposes a new algorithm which is the neural network controller. The new algorithm uses the neural network instead of activation function to control object at the output node. As the controller is designed in simple structure neural network, input-output pattern problem is solved naturally and real-time learning become possible through general error back propagation algorithm. Application of the new algorithm of neural network controller gives excellent performance for initial and tracking response and it shows the robust performance for rapid load change and disturbance.

The purpose of this study is to discover how people can obtain the effects of Physical Self-Concept on the Self-Esteem, a mental well-being and Life satisfaction. The earlier studies about sports science show that continuous physical exercise influences human beings to develop self-concept and self-esteem. On the base of this assumption that exercise is effective not only to enhance physical strength but also to develop self-esteem by affecting physical self-concept, the study was proceeded. For the study, 450 pieces of questionnaire, which consist of 108 questions to evaluate self-esteem, emotional satisfaction and satisfaction in daily life were contributed to a group of students who are dance majors, gymnastics majors and other non-physical related majors in Universities located in Gwang-ju. This study investigated the self-esteem, mental well-being and life satisfaction by the high and low physical self concept. The data were analysed using two-way ANOVA, correlationship analysis, and post hoc comparison method using Tukey HSD. Through the questionnaire analysis, following conclusion turned out. First of all, it proves that a group of people who dance or exercise for continuous physical activities have high physical self-concept. In particular, a group of people who exercise showed higher physical self-concept. Second, a group of people who have high physical self-concept showed higher self-esteem and emotional satisfaction compared to a group of people who have less. Accordingly, it showed. that physical self-perception, self-esteem and emotional satisfaction are highly interrelated.

이윤주(Yoon-Ju Lee),최준호(Jun-Ho Choi),정소연(So-Yeon Jeong),이재원(Jae-Won Lee) 한국신재생에너지학회 2019 신재생에너지 Vol.15 No.2

In this study, a hydrothermal pretreatment of an empty fruit bunch (EFB) was carried out to improve the fuel properties. The possibility of reusing the hydrolysate generated from this process was examined using three different adsorbents (XAD 4, XAD 16 resin, and activated carbon). The degradation rate was 19.46% during the hydrothermal pretreatment, which increased to 20.05-26.77% by the reuse of hydrolysate depending on the adsorbent. The inorganic compound and degradation products contained in the hydrolysate were removed by the adsorbent. In particular, the total phenolic compounds were removed effectively (3.9-49.6%) by activated carbon. The inorganic compounds were removed by activated carbon with a 2.8-12.4% removal rate. The heating value was increased slightly by the reuse of hydrolysate. Finally, the fuel properties were improved by removing the inorganic compounds and improving the heating value.

이윤주(Lee, Yoon Ju) 한국모델콘텐츠학회 2021 한국모델콘텐츠학회지 Vol.2 No.2

이 연구는 국내 모델전공자의 DISC 행동유형에 따른 전공만족도와 수업참여도의 차이가 있는지를 알아보기 위해 이루어졌다. 이를 위해 국내에서 모델을 전공하는 대학생을 모집단으로 선정하였다. 설문지의 표본추출은 비확률 표집방법(non-probability sampling) 중 하나인 편의 표본 표집법(convenience sampling)을 사용하였고, 설문작성은 연구대상자가 읽고 직접 작성하는 자기평가기입법(self-administration method)을 통해 이루어졌다. 자료처리는 빈도분석(frequency analysis), 탐색적 요인분석(Exploatory Factory Anaysis: EFA), 내적일관성 검사를 통해 얻은 Cronbach’s ⍺ 계수를 이용하여 신뢰도 분석, 일원분산분석(one way-ANOVA) 분석을 실시하였다. 결과는 다음과 같다. 첫째, 국내 모델전공자의 DISC 행동유형에 따른 전공만족도는 I형=사교형(M=4.19)이 S형=안정형(M=3.79)과 D형=주도형(M=3.71)보다 높았다(F=7.655***). 둘째, 국내 모델전공자의 DISC 행동유형에 따른 수업참여도는 C형=신중형(M=3.82)과 I형=사교형(M=3.53)이 D형=주도형(M=3.15)과 S형=안정형(M=3.11)보다 높았다(F=14.602***). 종합적으로 이 연구를 통해 모델전공자들의 행동유형에 따라 전공만족도와 수업참여도에 차이가 있음을 알 수 있었다. 이에 이 연구는 다양한 행동유형에 맞는 맞춤형 형태의 교수법과 수업구성원들과의 확장된 상호작용, 커리큘럼(curriculum)이 필요함을 시사한다. This study aimed to investigate the differences of major satisfaction level and class participation according to the behavioral types of DISC in the model majors in Korea. To do so, the university students majoring in model were selected as the study population in the colleges and universities located in Seoul, North Gyungsang Province, and South Cholla Province. Samples were selected using convenience sampling which is one of non-probability sampling methods and the survey forms were collected after preparations by self-administration method which the study subjects read and answered directly. Upon the survey results from October 2017 to June 2018 for 9 months, the total number of respondents was 238 and 234 survey forms were used as the final analysis excluding 4 data with continuous answers which would lower the reliability of the study. Data processing to verify the study problems was performed by frequency analysis, Exploratory Factory Analysis(EFA), reliability analysis using Cronbach's a coefficient from internal consistency test, K-cluster analysis, and one way ANOVA. Based on the study methods and data analysis, the following results were deducted: First, I type= Influence (n=77) was the most prevalent while C type = Conscientiousness (n=32) was the least upon the distribution result of DISC types among the model majors in Korea. Second, the major satisfaction level of I type=Influence (M=4.19) was higher than those of S type = Steadiness (M=3.79) and D type = Dominance (M=3.71) upon the result of post-hoc analysis (Scheffe) according to the behavioral types of DISC among the model majors in Korea (F=7.655***). Third, C type = Conscientiousness (M=3.82) and I type = Influence (M=3.53) showed higher class participation than D type = Dominance (M=3.15) and S type - Steadiness (M=3.11) upon the result of post-hoc analysis (Scheffe) according to the behavioral types of DISC among the model majors in Korea (F=14.602***). Overall, it was found through this study that various behavioral types were shown in the model majors and class satisfaction and participation rate were different by the behavioral types. Hence, this study implicates the needs of customized teaching methods and curricula to meet a variety of behavioral types.
