As the number of blog users has been increasing significantly, a lot of studies have been carried out to find out what makes people use a blog or feel satisfied with it. However, most of the previous studies assumed that dissatisfaction is the opposite of satisfaction and a person who is dissatisfied with a blog does not use it, failing to explain about blog users who do not feel satisfied with their blogs but use them continually. In addition, the studies found out just blog users' motives and satisfying factors in using blogs, and did not suggest any way to improve and promote blog services. Against this backdrop, this study conducted a survey of blog users in order to examine how the satisfying factors of a blog selected through a prior study affect both satisfaction and dissatisfaction of a user. The survey results showed that the satisfying factors are divided into two groups: group A which affect satisfaction and dissatisfaction equally, and group B which affect them differently. Based on the results, this study subdivides group A into high involvement factors and low involvement ones, and group B into motivators, which strongly affect satisfaction, and hygiene factors, which strongly affect dissatisfaction. According to characteristics of each group, this study suggests ways to improve and promote blog services.

This research examines educational effects on students' scientific process skills after applying a robot utilized MBL learning. Surveys and interviews concerning robot based science lessons were also conducted. The students were divided into experiment group who used the robots and controlled group who used traditional learning method with textbook and experiments. The result showed some significant differences in scientific measurement, prediction and inference(<.05). In contrast, no significant differences were found in observation and classification. The students answered the survey that the robots helped them understand science better and made science lessons more interesting.

The computed tomography(CT) simulation tool provides virtual experimental environment without using a high cost medical equipment. We made teaching materials for the CT simulation tools and educated the students and entry level of radio-technologists. We divided the experimental objects into two groups; students who took only theoretical classes (group 1) and students who took both theoretical and simulation classes (group 2). The results showed that the group 2 outperformed group 1 significantly, which indicates that the simulation program provides a good educational material for not only students but also radio-technologists.

The purpose of this research is to define body characteristics of middle-aged men at ages between 35 and 55 whose physical changes are very prominent, by comparing the measurement data collected from this age group. This research also classifies different body types, and provides basic data for designing slacks' original forms according to each body type. Based on factor analysis of the measured data, seven key factors are grouped. And five different body types are classified based on the cluster analysis using factor marks. Type 1 refers to those who are tall and standard. This body type is characterized by trapezoid body shape when looked from the front, and slim abdomen when looked from the side. Type 2 refers to short and a little fat body shapes, with trapezoid front and protruding hip and abdomen. Type 3 refers to tall and fat body shapes, with rectangular front, protruding abdomen, and slim hip. Type 4 refers to those who are of medium height and a little obese, with rectangular front and protruding abdomen and hip. Type 5 refers to short and obese body shapes, with rectangular front, slim abdomen, and protruding hip. 12 items are available to judge middle-aged men's low body types and the hit ratio is 90%.

Purpose: The purpose of this study was to determine whether, in patients with acute coronary syndrome (ACS), according to the mode of arrival affect the emergency medical process. Methods: The participants of this study were 118 adult patients (46 patients admitted by emergency medical services (EMS), 48 walk-in patients, and 24 transferred from other hospitals) admitted to the emergency departments at one regional-level medical center who underwent coronary angiography between January 1, 2016 and December 31, 2017. To compare treatment courses, the median values of the following variables were compared among groups: symptom to door time; door to triage time; and door to ECG time. All data were analyzed using SPSS program. Results: Based on the initial assessment at triage, there was a significantly greater proportion of Korean Triage and Acuity Stage (KTAS) Level 1 or 2 among patients admitted by EMS than among walk-in patients. All three analyzed variables were lower in patients admitted by EMS than in the other two groups. Conclusion: Our results show that ACS patients who accessed EMS reached the emergency center faster after symptom onset, received initial triage assessment at earlier stages, and underwent sooner important examinations (i.e., the 12-lead ECG).

Purpose : The purpose of this study is to get higher discriminability of the QSCCII on Taeumin. Methods : I analysed each item response rates on QSCCII of those who had been tested and diagnosed as Taeumin, Soeumin, Soyangin respectively by frequency analysis and reviewed Taeum scale of the current QSCCII by reliabiliry analysis and discriminant analysis. Results : 1. From the 758 results of QSCCII of those who were examined by professors, I made a revised Taeum scale which is consists of 17 items including 14 existing Taeum scale items and 3 new items from the other scales. 2. Reliability of revised Taeum scale is 0.5983, higher than that of existing Taeum scale, 0.5922. This means that revised Taeum scale reflects Taeumin's character more reliably than the existing one. 3. Hit-ratio of revised QSCCII on Taeumin is 60.3%, 2% lower than that of existing QSCCII.

The study aims to furnish the data for the study of invigorating communities of various ages including old people living alone. Furthermore, it seems that the laddering method and kj method can be useful for the study of various attitude survey. This study attempted to extract necessary factors for space for community behavior of elderly people living alone using laddering survey method and KJ rule on a sample of elderly people who live alone in three different rental housings. The keywords that were drawn from the perception survey through laddering were divided into small, middle and large classification using KJ rule. Mostly identical keywords were extracted in the three complexes, implying that there is no difference of perception among the three complexes in this survey. According to the large classification where KJ rule was applied, there were six necessary factors for space for community activity of elderly people living alone in rental housing including spatial consideration, communication, resting space, nature-friendliness, health promotion and Secure identity, which were the same for all of the three complexes.

This study examined how news has covered games since the decision to include gaming disorder in ICD-11. Data were 694 news article on games in five major newspapers. The results indicated the following: While the proportion of reports on game industry was high, those reports were mainly straight news announcing industry status and corporate management status. Reports on game policy focused on regulations, particularly game addiction or disorder. Reports on game uses and effects showed very low rates, but they have followed the existing practices of reporting games as the cause of extreme crimes and deviant behaviors.
