Purpose: This study aimed to systematically analyze the reliability and validity of Korean versions of mobility and gait assessment tools for patients with stroke. Methods: Two reviewers conducted an independent literature search and systematically reviewed the literature. Literature published until June of 2017 was searched using search engines for electronic databases. The 2 reviewers reviewed the title and abstract of each article. Among the articles examined, we read the full text of those judged to be suitable for our study. We classified the selected data into research methods and results. The determination was made through mutual agreement. Results: The reviewers selected 5 articles related to the purpose of this study. The DGI was found to be moderately associated with BBS, 10MWT, and TUG in intra-rater reliability (ICC=0.92), inter-rater reliability (ICC=0.88), and concurrent validity tests. The FGA demonstrated a high level of reliability with intra-rater (ICC=0.92-0.95) and inter-rater reliability (ICC=0.91, 0.95). The intra-rater reliability of the RMI was high at ICC=0.98. Its concurrent validity showed a high association with STREAM and BI. The intra-rater reliability of the MAS was ICC=0.75-0.99. Its inter-rater reliability was very high, exceeding 0.99. The inter-rater reliability of the Tinetti-gait Scale was ICC=0.91, and its concurrent validity was moderately associated with the DGI, 10WMT, OLST, FM-L/E, and STS. Conclusion: The results of this study revealed that the reliability and validity of the Korean versions of the mobility and gait assessment tools were high.

This thesis has two objects： Firstly, the arrangement of basic data and formulating a system of experiment and practice in home economics and Secondly, the groping the way of improving the problems raised in the home economics education spot. A questinaire is used as the research tools for the fitness of content, of experiment and practice in the home economics and SPSS/PC(sup)+ and Scheffe Test are used for investigation. The results are as follows. 1. Students recognize the importance of experiment & practice more than the teacher. In the type of middle school teachers engaged in the girl’s middle school recognize the importance of experiment & practice more than those of coeducation middle school. 2. The percent of the school which executes over the 50% of experiment & practice in the contents of text book is 70%. The most numerous in the sphere of guiding is ‘seperate practice of student’. The reason of not executing the experiment & practice are ‘the concentration of the theory education’and ‘the lack of equipment and tools’3. Practice room for cooking was mostly established, but practice room of sewing was established only 5.6%. The contents of textbook for clothing sphere can be executed by using the equipment & tools of school only 9.2%. 4. 40% of the students feel that the content level of experiment & practice is difficult. Most of the students feel that the content level of experiment & practice, especially in the sphere of clothing, in unproper on the level fitness of contents by grade. 5. Most of the students assent on the positive effect for the degree and the most important cause for its not contributing to the everday life is the lack of experiment & practice in school. 6. Most of the students feels positively on the interest degree of content and the students who though much of the experment & practice feels positively on the interest degree of content.

The importance of the standards and its related texts established by Codex Alimentarius Commission (CAC) had been increased by the Agreement of Application of Sanitary and Phytosanitary Measures (SPS Agreement) in World Trade Organization (WTO). To meet the needs of WTO SPS Agreement, biennial CAC meeting had been changed to every year. This study was conducted to analyze the effects on interval between CAC meetings. The years of adoption, revision and amendment of CAC texts were collected from the official standard list and individual texts from CAC homepage. The period since establishment of CAC was divided into four groups by starting negotiation of Uruguay Round, WTO foundation and reducing the interval between CAC meetings. The collected data were analyzed by SPSS program. The numbers of CAC standards, guidelines, recommendations, maximum residue levels, and miscellaneous texts were 202, 56, 46, 3 and 5, respectively. Since 8 documents didn't contain the adoption year, these texts were eliminated to analyze adoption year. For adoption, annually 11.26 texts were established since establishment of CAC and there were no significant difference among the 4 groups. However the average numbers of revisions and amendments of adopted texts for overall periods and for each period were 7.56, 0.93, 6.50, 17.20 and 19.75, respectively. The average numbers of overall decisions, defined as summation of adoption, revision and amendment of texts, for overall periods and for each period were 12.37, 6.27, 9.00, 17.40 and 29.25, respectively. There were significant differences by the WTO foundation and the interval between CAC meetings. The reduced interval of CAC meetings influenced to increase number of revisions and amendments of adopted texts, but not yet adoption of new text.

Purpose : The purpose of this study is to investigate the corneal topography changes as a result of near task in myopes and emmetropes. Methods : Thirty university students, aged from 18 to 24 years old, were randomly selected. They were divided into two refractive groups of fifteen each : myopia and emmetropia. The corneal topography of each subject was measured with the Eye-Sys Videokeratography system. Measurements were taken : before and after 30 minutes of near task (copy N10 text at 20 cm working distance). Both simulated keratometry and semi-meridian keratometric map program were used in the data analysis. Results : Our results reveal no significant changes in both simulated keratometry and semi-meridian presentation as a result of near task for both myopes and emmetropes, except a significant change (p<0.05) found at the flattest meridian of the central (3 mm) portion of the corneal topography after near task for emmetropes only. Conclusions : We conclude that the corneal topography, does not change significantly as a result of near task in both myopes and emmetropes.

The purpose of this study is to describe the experience of visually impaired academic researchers' use of scholarly contents and to explore intrinsic nature of the experience. In-depth interview was conducted with a total number of twelve visually impaired academic researchers and the data were analyzed using Colaizzi's phenomenological research method. A total of 107 significant statements were extracted, divided into 44 themes and 12 theme clusters. The statements were then classified into four categories. The 'scholarly contents acquisition and use' category has to do with difficulties that these experience when negotiating with internet sites with poor web accessibility and full-text availability. The 'changes in perception and emotions' category deals with transitions in perception and mood experienced by visually impaired academic researchers' over time. The 'relationships with support personnel' category includes issues related with the difficulty of securing support person, support person's inadequate level of competence, and establishing/sustaining personal relationships. Finally, the 'improvement requirements' category includes issues that these researchers want resolved with regard to contents acquisition and use.

Recently, with improvement of internet service technology, web service has been affecting the environment for computing user. Not only current events, economics, game, entertainment, but also personal financial system is processed by web pages through internet. When data transmission is implemented on the internet, webpage acquire text form code and transform them to DOM information, and then shows processed display to user by web browser. However, those information are not only easily accessed by diversified route, but also easily deformed by intentional purpose. Furthermore, it is also possible to acquire logon information of users and certification information by detouring security mechanism. Therefore, this dissertation propose the method to verify integrity of web contents by using BHO which is one of the Add-On program based on MS Internet Explorer platform which is one of major web browser program designed by MicroSoft to detect any action of webpage deformation.

Objectives : This study was designed to evaluate clinical evidence of moxibustion treatment for knee pain. Methods : All processes were independently carried out by three investigators. A literature search was performed in 3 databases from their inception to May 2015. Ten reports were found based on their title, abstract and text. Following this, data extraction and analysis were done using a risk of bias(ROB) and through an assessment of multiple systematic reviews(AMSTAR). Results : 10 studies(6RCT, 2SR, 2CR) were included. Generally, indirect moxibustion was used for knee pain, but only one study indicated the use of direct moxibustion. Moxibustion was shown to be effective in treating knee pain, and the number of required treatments was fourteen on average. In assessing risk of bias, indefinite and uncertain information made all included trials subject to a high risk of bias. On the other hand, SR showed all evaluation items in the assessment of multiple systematic reviews, with the exception of an included or excluded studies list. Conclusions : Because of deficient study design or limited research planning, there is not sufficient evidence to allow for any conclusion about the efficacy of moxibustion for knee pain. Therefore, well-designed high quality trials are needed from now on.
