Presence Agent Server는 사용자의 Presence 정보를 PUBLISH를 통해 전달 받고, SUBSCRIBE에 의해 맺어진 Subscription으로 NOTIFY 메시지를 사용하여 전달해주는 역할을 한다. IMPP 단말은 PUA(Presence User Agent)의 기능을 기본으로 가지며, 경우에 따라서는 PA(Presence Agent)의 기능까지 포함하는 경우도 있으나, Presence Agent Server는 주로 단말이 PUA의 기능만을 가지고 있을때 유의미한 동작을 수행한다. Presence Agent Server는 오직 PA의 기능만을 담당하며, 타 Subscriber로부터의 subscription 요청을 처리한다. 그리고 확장된 개념의 presence Agent 서버는 Resource List Event Package까지 지원을 하며, Subscriber는 단 한번의 subscription으로 N개 이상의 Presence 정보를 가지게 할 수도 있다. 본 고에서는 Presence Agent Server의 기능을 구현하기 위하여 기능별로 구현 모듈을 분리시키고 각 모듈별 기능을 기술하는 것을 목적으로 한다. 그리고 각 모듈간 연동을 위한 APT를 단순화 하기 위하여 이벤트 매니저/핸들러로 분리를 시킨 방법과 정보 저장을 위한 데이터베이스 API Instruction Set을 나열 및 설명한다.

The purpose of this study is to develop a Framework for Performance Assessment in Science Education(FPASE). Science educators in the past have paid more attention to science curriculum and teaching strategies than assessment. In recent years, attention has turned toward performance assessment which addresses the concerns of science curriculum and instruction, and which is consistent with goals of science education at various levels of interests. Science educators are trying to do performance assessment, yet they don't have a framework that is highly qualified in terms of science educational objectives for the future, and advantages of performance assessment. We, therefore, have developed a framework for performance assessment in science education, which may be useful for science teachers to understand and assess their students' abilities. We have extracted seven domains covering students' various abilities as the important objectives of science performance assessment and grouped them into three categories: General, Science specific, and Intermediate abilities. And we developed a F-PASE with a three dimensional solid figured structure, and illustrated it as the configuration of a com. F-PASE is useful for science teachers to develop and select a science performance assessment as well as have a more advanced understanding of their students' abilities. It is a creative and novel assessment framework in terms of structure, configuration, functions and meanings. It also suggests a new vision of an assessment framework in science education.

Purpose: The purpose of this study is to provide a disease management, nutrition education, and group exercise program for three months to the moderately frail elderly whose physical functions have deteriorated, and to investigate its effects in order to develop an intervention program. Methods: As a quasi-experiment, this study was conducted based on non-equivalence studies designed as a similar experiment. The milk intake group and calcium intake group participated in the disease education, individual nutrition education, and group exercise program for three months, and the control group was visited once in the three months by a nurse who provided disease education, nutrition education, and oral instruction of exercise, and asked them to exercise on their own every day. For the data analysis, ${\chi}^2$-test, ANOVA and $Scheff{\acute{e}}$ test were used. Results: After three months of intervention, there was a significant difference in the frailty level (p=.029) and bone density (p=.001) between the groups. Conclusion: The comprehensive intervention program had an effect on the bone density and the frailty level of the socially-vulnerable and moderately frail elderly, suggesting that the program can be used as a nursing intervention to prevent functional deterioration and damage of the moderately frail elderly.

The purpose of this study is to investigate the effect of real-time remote video instruction using zoom on learners' English reading achievement. The study also sought to identify the efficiency of zoom video lectures and consider supplementing them by surveying learners' opinions and satisfaction regarding zoom video lectures. To this end, control and experimental groups were set up, and two achievement tests and a questionnaire were conducted. The study's results demonstrated that zoom video lectures have a positive effect on learners' English reading achievement. The questionnaire found that learners are satisfied with zoom video lectures for the following reasons: 'increased interest in and motivation towards learning', 'self-directed learning', 'active interaction', 'ease of access', 'ease of information retrieval'. At the same time, the questionnaire also found that some learners are dissatisfied with zoom video lectures due to 'mechanical errors or defects', 'poor audio quality', and 'the need to add customized functions for efficient classes'. In practice, zoom video lectures must be supplemented with automatic attendance processing, convenient data upload and download, and more efficient video screen management. Given the recent increase in online classes, we, as instructors, must develop teaching activities and/or strategies for video lectures that can encourage active participation by learners.

This article examines the ways in which language can be exploited in the manipulation of the reader's interpretation of a text to make him/her take certain lines of thought according to the writer's persuasive intents. Such functions of language provide valid foundations to support the teaching of critical reading skills and to explore an adequate approach to discourse analysis. A pilot study was conducted to find out the extent to which the reader can be coaxed into thinking in some fashions guided by specific linguistic devices employed for ideological texts. Forty-seven subjects divided into two groups (humanities majors and natural science majors at undergraduate level) joined the two-fold questionnaire surveys intended to look at their critical reading abilities. The empirical results indicate that college students whose majors are humanities were more inclined to take a holistic approach in processing commercial advertisement texts and their abilities for critical interpretation appeared to be lower than those of the subjects whose majors are natural sciences, who showed a relatively high tendency to take an analytical approach in decoding the textual facts. As a consequence, pedagogic implications for increasing critical reading abilities have resulted in a set of analytical procedures concerning ideological texts which is linked with instructional guidelines to emphasize the importance of the reader's logical and analytical reasoning power, entirely accepted as a general prerequisite for cracking the covert language gambits.

The Arithmetic Logic Unit (ALU) is a core element of a computer processor that performs arithmetic and logic operations on the operands in computer instruction words. We have developed and tested an RSFQ multi-bit ALU constructed with half adder unit cells. To reduce the complexity of the ALU, We used half adder unit cells. The unit cells were constructed of one half adder and three de switches. The timing problem in the complex circuits has been a very important issue. We have calculated the delay time of all components in the circuit by using Josephson circuit simulation tools of XIC, $WRspice^{TM}$, and Julia. To make the circuit work faster, we used a forward clocking scheme. This required a careful design of timing between clock and data pulses in ALU. The designed ALU had limited operation functions of OR, AND, XOR, and ADD. It had a pipeline structure. The fabricated 1-bit, 2-bit, and 4-bit ALU circuits were tested at a few kilo-hertz clock frequency as well as a few tens giga-hertz clock frequency, respectively. For high-speed tests, we used an eye-diagram technique. Our 4-bit ALU operated correctly at up to 5 GHz clock frequency.

One of the key tools in assessing the seismic vulnerability of the structures is the use of fragile functions, which is the possibility of damage from a particular damage surface for several levels of risk from the seismic movements of the earth. The aim of this study is to investigate the effect of two categories of earthquake events on the fragile curve (FRC) of the steel construction system. In this study, the relative lateral displacement of the structures is considered as a damage criterion. The limits set for modifying the relative lateral position in the HAZUS instruction are used to determine the failure modes, which include: slight, moderate, extensive and complete. The results show, as time strong-motion increases, the probability of exceeding (PoE) increases (for Peak ground acceleration (PGA) less than 0.5). The increase in seismic demand increases the probability of exceeding. In other words, it increases the probability of exceeding, if the maximum earthquake acceleration increases. Also, 7-storey model in extensive mode has 20 and 26.5% PoE larger than 5- and 3-storey models, respectively.

Purpose: This research study not only examine the relationship between cognitive function, IADL, depression and quality of life, but also clarifies factors impacting quality of life for the elderly. The purpose of this study is to administer health promotion programs and to improve quality of life for the elderly. Methods: Data were collected from May 20, to June 10, 2014. The participants were 157 elderly persons with mild cognitive injury (MCI), who had under 23 points on MoCa-K from three different senior welfare centers in Daejeon. The questionnaires were conducted by four university students after receiving instruction from the researcher and consisted of general characteristics, cognitive function, depression and quality of life. SPSS WIN 19.0 program was used for data analysis. Results: Cognitive function showed positive correlation with quality of life (r=175, p=.028). IADL did not show correlation with quality of life (r=-.005, p=.947). However cognitive function(r=-.344, p<.001) and depression (r=-.623, p<.001) showed negative correlation with quality of life. In addition, the factors impacting quality of life were cognitive function (${\beta}=.14$, p=.29) and depression (${\beta}=-.61$, p<.001) which accounted for 39% of quality of life. Conclusion: These findings showed that the participants had depression and their cognitive function was low. As a result, the more participants' cognitive function decreased, the more their quality of life decreased. In addition, the more their depression decreased, the more their quality of life improved.

This study examines spoken interlanguage of Korean learners of English, focusing on the distribution of modal verbs and devices of epistemic modality. (Semi-) spontaneous speech data were collected from four students participating in a self-organized study group for seven months, which produced a corpus of about 55,000 words. The data analysis reveals the following: 1) The frequency of the modal verbs produced by the learners was lower than that of native speakers; 1.99 vs. 2.32 tokens per 100 words. The range of the modal verbs used by the learners was also very limited, with over-reliance on can (43%). 2) The grammatical categories of the devices marking epistemic modality were in the order of adverbs, lexical verbs, and modal verbs, with a high frequency of a few items in each category. 3) Lexical items conveying certainty and modals of obligation were preferred over markers of weaker commitment, resulting in speech characterized by firmer assertions and a more authoritative tone, a potential cause for pragmatic failure. 4) A weak developmental change was observed in the frequency of modal verbs, but not in their functions over the seven month period of data collection. L1 influence, L2 proficiency, mode of communication, and instruction effects are discussed as possible variables involved in the distribution patterns observed.
