Recently with the development of Web services by utilizing a variety of web content, the studies on user experience and personalization based on web usage has attracted much attention. Majority of personalized analysis are have been carried out based on existing data, primarily using the database and statistical models. These approaches are difficult to reflect in a timely mannerm, and are limited to reflect the true behavioral characteristics because the data itself was just a result of customers' behaviors. However, recent studies and commercial products on web analytics try to track and analyze all of the actions from landing to exit to provide personalized service. In this study, by analyzing the customer's click-stream behaviors, we define U-Score(Usage Score), P-Score (Preference Score), M-Score(Mania Score) to indicate variety of customer preferences. With the devised three indicators, we can identify the customer's preferences more precisely, provide in-depth customer reports and customer relationship management, and utilize personalized recommender services.

The purpose of the study was to investigate the characteristics of energy use behaviors and energy saving consciousness of multi-family housing residents. The energy referred to in this study includes electric energy, heating energy and water usage. This study was conducted from a survey carried out in Seoul and Gyeonggi-do. The results of the study are as follows: First, among the survey questions, the only positive energy saving behaviors shown by the occupants was turning off the lights and the television, and in the use of kitchen appliances; it could therefore be concluded that, in general, energy saving attitude and consciousness were not sufficient to reduce energy consumption. Second, the results showed high mean scores for the behaviors which were easy to control, such as turning off lights and televisions, and low mean scores for the behaviors which required extra effort to completely cut off electricity energy such as pulling out the plugs of electronic appliances. Third, it was found that the occupants generally showed the tendency to save heating energy. However, in cases where the occupants were required to continuously and directly experience indoor temperatures, they expressed passive attitudes toward saving energy. Fourth, they showed wasteful attitudes toward water usage by leaving the tap running when taking showers and washing their faces. Fifth, while they showed a strong energy saving consciousness, they also showed a passive attitude about putting this into practice; there was therefore some gap between attitude and behavior. Lastly, among the socio-demographic factors, age and family lifecycle were very important factors affecting energy use and energy saving consciousness.

The purpose of this study was to investigation the variables that affected the generational transmission of household work form mothers to their married daughter. The subjects were 415 married daughters and their mothers living in Seoul and metropolitan areas. Statistical techniques used for this study included descriptive statistics and multiple regression analysis. The results of this study were as follows : First, married daughters; value of household work was significantly affected by total periods of marriage of daughters, daughter's perceived similarity to their mothers' household work. Second, married daughters' preference for household work was significantly affected by mother's occupation (managerialㆍprofessional), mother's perceived similarity, daughter's experience of living with mother-in-law, daughter's sex-role attitude, and daughter's perceived similarity. Third, married daughters' ability to do household work was significantly affected by total periods of marriage for mothers, mother's perceived similarity, and daughter's perceived similarity. Fourth, married daughters' standard of household work was significantly affected by mother's perceived similarity, daughter's occupation (techniciansㆍclerk), daughter's monthly income, and daughter's perceived similarity. Fifth, married daughters' usage level of home equipments was significantly affected by mother's birth order, mother's education, mother's occupation (managerialㆍprofessional), daughter's birth order, daughter's education, and daughter's monthly income. Sixth, Mother related variables had greater power than daughter related ones in explaining daughters' values and preference for household work value and preferences and usage of home equipments. In conclusion, married daughter's consciousness and performance of household work were significantly influenced by their mothers. It was especially so in daughter's usage level of hoe equipments. Accordingly, the results of this study support the existence of generational transmission of household work from mothers to their married daughters with regard to its consciousness and performance. Findings of this study have implications for counsellors, practitioners and educators.

The purpose of this study is to investigate the impacts of individual difference toward technology and situational influences on use intention of Self-Service Technology. While the previous research related to SSTs focuses on individual tendency toward technology, little research has been done on the impact of situational influences on usage intention of SSTs. This study proposed Technology Readiness Index for measuring individual tendency toward technology and categorized situational influences into two dimensions: location convenience, employee presence. The empirical testing of the research was conducted on 20' users who have prior experience in using SSTs except for ATMs in bank. This study demonstrated that the people who are favorable emotions positively affect SSTs. Also this study confirmed that it is effective to build strategies to form favorable attitude and usage intention of knowledge of SSTs rather than method through service employees. Finally, SSTs were distributed for customers.

The purposes of this study were to assess current status of respirator usage among workers in the small-scale industries and to identify those factors causing respirator wearers not to continuously wear respirators during work. Total 168 workers participated voluntarily in the survey. In order to cover all possible reasons, though not exclusive, 33 diverse questions were developed based upon the results in the published literatures and from researchers' own experience. The most common type of respirator worn was the disposable single-use respirator(42%). However, masks made of gauze, which should not be considered as a respirator, were widely used (38%). Only 28% of respondents indicated they wear respirators continuously during work. The major reasons for removing respirators include, in descending order of frequency, difficulty in breathing (46%), sweating (39%), bothered by frequent removal (21%), inadequate mask size (19%) and hot air temperature inside the respirator (19%), etc. In addition, minor reasons including mask design, administrative, and personal reasons were also identified. These reasons should be considered in a well designed respirator program in order to improve workers' acceptance and usage of respirators.

The purpose of this study is to find any contradictions which arise with the use of Wiki in the classroom, and to address such contradictions in order to promote learning among LIS students. This study employed a multi-methodology, including Wiki usage analysis, and interviews with 12 students who participated in an LIS class. Observations revealed that group projects are common in academic classes. Interviewees agreed that their performance through collaborative efforts was higher than that through individually performed activities. However, there were no pre-experiences with Wiki in learning and task-oriented cooperation which gave rise to a controversy. In addition, even though a new technology, as a more advanced form, was suggested, students cooperated with their peers according to their tradition without using the recommended new technology. Therefore, students should be taught about Wiki usage and experience the effective learning which is available to them through collaboration with their peers. Additionally, LIS curriculum should incorporate relationship-oriented activities using Web 2.0 applications with the expectation of enhanced learning among students.

Purpose - This study aims to empirically verify the impact of media richness, social presence, and prior life satisfaction on various continual usage or withdrawal behaviors of SNS users via both a positive path of satisfaction and a negative path of relative deprivation. By identifying these causal paths, we observe dynamic interactions of SNS user psychology in a balanced view, and provide some implications about design principles for SNS providers. Research design, data, and methodology - We developed 16 hypothesis based on media richness theory, social presence theory, social comparison theory, the literature about relative deprivation, and the literature about the various reactions of IS users. The rich SNS media, social presence recognition among peer SNS users, and prior life satisfaction could generate positive experience, attitude, and virtuous behavioral intentions among SNS users. At the same time, rich media, low social presence, and low prior life satisfaction could generate relative deprivation and could increase withdrawal behavioral intentions such as refusal to provide information, misrepresentation of information, and removal of uploaded information in SNS. Scenario surveys were conducted to collect data from potential SNS users. Data from 357 surveys were collected and analyzed through a PLS algorithm to test the hypotheses. Results - Media richness, social presence, and prior life satisfaction could significantly increase perceived enjoyment, satisfaction, and behavioral intention of continual usage and knowledge sharing. They also could significantly decrease refusal and misrepresentation intention. Relative deprivation is significantly decreased only by prior life satisfaction. Relative deprivation could not significantly decrease satisfaction, but it could significantly increase misrepresentation and removal intention, which could be regarded as information distortion intention. Conclusions - SNS providers should focus on developing rich media and social presence support because these two variables could impact the positive experiences of SNS users. Moreover, the positive experiences could heavily influence SNS user behavior. Some management is needed to prevent relative deprivation and its consequences of misrepresentation and removal intention. SNS providers should prevent SNS users from excessive image misrepresentation and removal as this information distortion could be the source of relative deprivation.

The purpose of this study is to investigate the effect of wearing a weightlifting belt, which is an auxiliary equipment used during squat, by measuring and analyzing biomechanical difference in lower limb and proposing safer and to suggest a more effective exercise method for general population. Selected 8 male participants in their 20s who have not performed regular resistance exercise for at least a year, but have experience of performing squat. The comprehensive method of study is as follows: subjects were notified of the purpose of the study and were told to practice warm-up and the squat motion for the experiment for 20 minutes. When the participant believed they were ready to begin, the experiment was started. At controlled points, foot pressure distribution sensor has been installed. Then left and right feet have been placed on the pressure distribution sensor, from which data for successful squat position that does not satisfy the criteria for failure have been collected and computed with Kwon3D XP program and TPScan program. For data processing of this study, SPSS 21.0 was used to calculated mean (M) and standard deviation (SD) of the analyzed values, and paired t-test has been conducted to investigate the difference before and after wearing the weightlifting belt, with p-value of ${\alpha}<.05$. As for time consumed depending on usage of weightlifting belt in squat, statistically significant difference has been found in P2, which is recovery movement. Lower limb angle depending on usage of weightlifting belt in squat has shown statistically significant difference in E1 foot joint(p<. 001). There has been statistically significant difference in E2 knee joint. Foot pressure percentage depending on usage of weightlifting belt in squat were found to be statistically significant (p<. 01) in both regions of anterior and posterior foot.

Objectives: Pharmacopuncture is a Korean medicine treatment that combines acupuncture and herbal medicines. The aim of this study was to investigate the current usage status of pharmacopuncture for insomnia among Korean medicine doctors (KMDs). Methods: We conducted a self-reporting online survey targeting KMDs from February 23 to March 15, 2021 with cooperation of the Association of Korean Medicine. Responses of 957 KMDs were analyzed. Results: Types of pharmacopuncture mainly used in treatment for insomnia were placenta pharmacopuncture and Hwangryunhaedok-tang pharmacopuncture. Cephalic and facial region were preferred as the treatment site. For one treatment, total usage of pharmacopuncture was more than 0.5 cc but less than 1 cc. Among respondents, the largest number of respondents thought that clinical experience and patient symptoms were important as selection criteria of acupoints using Pharmacopuncture for insomnia. Average treatment duration of using Pharmacopuncture for insmonia was more than 4 weeks. Most KMDs preferred treatment for one to four times a week regarding the treatment cycle. The use of Pharmacopuncture for insomnia was recognized as having a good effect, although other KMDs were concerned about the insufficient evidence and the high cost due to non-reimbursement of pharmacopuncture therapy. Conclusions: In order to activate pharmacopuncture treatment for insomnia, it is necessary to secure effectiveness and safety through basic research, create evidence through clinical research, and reduce costs for patients.
