Objectives : The purpose of this report is to introduce a rare case of a patient with Chorea Hyperglycemia Basal Ganglia syndrome (C-H-BG) whose initial medical interventions were started 2 weeks after the onset, and to suggest the possibility of treatment using a combined Western-Korean medicine approach. Methods : A 75-year-old female C-H-BG patient complaining of persistent right-sided hemichorea was treated with a therapy that combined Korean and Western medicine from April 4, 2015 to April 29, 2015. Improvements of symptoms were measured by a motor assessment of Unified Huntington's Disease Rating Scale (UHDRS), Visual Analog Scale (VAS) and the number of involuntary movements. Results : Motor assessment of UHDRS, VAS and the number of involuntary movements all showed a gradually improving tendency during 26 days of admission treatment. However, the patient's hemichorea persisted. Conclusion : Rapid blood sugar control is the most important treatment for C-H-BG, because pathologic changes of basal ganglia seem to become irreversible as time goes by. A combined Western-Korean medicine approach to treating C-H-BG seems effective not only in reducing hemichorea, but also in the management of accompanying symptoms such as muscle pain and general weakness.

In order to see the effects of talker sidetone on a talker's speech level quantitatively when he converses with others on a telephone, we reviewed the measuring algorithm of speech level and assessed variation of speech level due to that of sidetone masking rating(STMR). We measured room noise effects on speech level, when STMR values were changed, as well. If we consider the effects of talker sidetone and room noise on speech level, the results of experiments suggest that a talker continuously tries to keep the psychological loudness of his own speech, heard by himeself via a telephone handset, at the constant and comfortable level by controlling his speaking level according as STMR value and room noise are change. That is, because the amount of his speech masked by his talker sidetone and room noise is different when STMR value and room noise are changed, we can see the tendency that he controls his speaking level in order to keep the perceived psychological loudness of his own speech to be constant.

Purpose: The aim of this study is to calculate U-factor of the window using international standard methods and compare quantitative and tendency difference focused on ISO standard 15099 and ISO standard 10077. And the result of ISO standard calculation methods is verified using thermal performance experiment to evaluate applicability of domestic certification system. This study is utilized a basis for activation of domestic window certification system. Method: First, 16 cases are selected that is combined a variety of frame, Glazing, spacer, etc. The selected cases were simulated using WINDOW&THERM based on ISO 15099 and 10077 calculation method. Second, experiment was conducted based on Korean standard condition. Then, it was compared the error of experiment and simulation results. Through this process, ISO 15099 and 10077 calculation methods were evaluated accuracy and utilization. Result: The results show that the difference of ISO 15099 and ISO 10077-2 is maximum 5.4%. The results of comparing U-factor errors based on the Korea standard experiment test found 2.4%. Consequently, it will be possible to combination calculation methods of ISO 15099 and ISO 10077 for a single window.

Background : Clinical practice guidelines are an increasingly familiar part of clinical practice. Moreover, rigorously developed evidence based guidelines has been widely used. However, in Korea, some of published documents as clinical practice guidelines have shown considerable disparity in structure, contents and quality. This is mainly because there is no consensus on the definition and quality standard of clinical practice guidelines. The purpose of this study was to draw consensus on the definition and the quality standard about clinical practice guidelines. Method : We developed a questionnaire about the definition of clinical practice guidelines with inclusion criteria(23 items) and the quality standard(30 items). We selected 9 experts who had prior experience in developing and implementing guidelines. Rating methods for appropriateness of items were adopted from the RAND method. Consensus was drawn in three rounds. Results : Of the 47 items agreed, 40 items were determined to be appropriate. Clinical practice guidelines were defined as "scientifically and systematically developed statements to assist practitioners and patients on making decisions about appropriate health care for specific clinical circumstances." Narrative reviews, systematic reviews or health technology assessment without recommendations, translation of foreign guidelines, guidelines for patients only and training manuals were not considered as clinical practice guidelines. For the quality standard of clinical practice guidelines, 27 items were deemed necessary. Conclusions : The consensus on the definition with inclusion criteria and the quality standard of clinical practice guidelines carries an important meaning as the first attempt to draw a general agreement in our society. The unique achievement of the consensus reflects the current status of clinical practice guidelines that there has been a high tendency to adapt foreign guidelines. We hope efforts of this kind will continue to bring improvement in clinical practice guidelines.

Background: Although the original version of the health-related quality of life (HRQOL) questionnaires are found to be acceptable, the cross-culturally adapted versions may not be comparable to their original version. Objects: To examine dimensionality and construct validity of two Korean versions of the brief version of the World Health Organization Quality of Life (WHOQOL-BREF) and EuroQOL-5 dimension (EQ-5D) questionnaires. Methods: A total of 77 cancer survivors undergoing palliative rehabilitation programs from two rehabilitation institutes was recruited from April 16, 2018 to June 26, 2019. The WHOQOL-BREF and the EQ-5D were filled out by the various cancer survivors following a particular session of rehabilitation programs. The scores were analyzed with Winsteps Rasch analysis computer program using the rating scale model. Rasch fit statistics were used to determine the dimensionality and the item difficulty calibrations of WHOQOL-BREF and EQ-5D. Results: All items except two, negative feeling, need treatment function and pain prevent activity (mean square [MnSq] = 2.42, 1.82 and 2.51, respectively), were found to be acceptable, while two items of the EQ-5D, anxiety/depression and self-care, were misfit (infit MnSq = 1.65 and 0.38, respectively). Item difficulty calibrations of WHOQOL-BREF match person ability measures (i.e., HRQOL) fairly well. However, the person ability distribution showed obvious ceiling effects for EQ-5D. All items of EQ-5D were appeared to be less challenged in comparison with those of WHOQOL-BREF. Conclusion: Item-level analysis using the Rasch model supports the quality of culturally adapted items used to measure the HRQOL one exception; that is, whether or not to include misfit items as part of the HRQOL measurements. Additionally, cancer survivors undergoing palliative rehabilitation programs appear to have more of a tendency to view the EQ-5D items as being more challenging than the WHOQOL-BREF.

Objective : This study was performed to confirm the hypothesis that the more one applies positive thinking, the less severe the symptoms of stress and the better the therapeutic responsein panic disorder and major depressive disorders. Methods : The study included 50 subjects with confirmed diagnoses of panic disorder or major depressive disorders. Positive thinking was assessed using Positive thinking scale. Beck Depression Inventory was used as a subjective measure for depression, and to ensure an objective measure for depression and anxiety, the Hamilton Depression and Hamilton Anxiety rating scales were implemented. Results : The positive thinking scale measured at the initial visit had shown a strong negative correlation with objective depression. Although patients with a high level of positive thinking had shown a tendency to respond better to the treatment, as compared with those with a lower level, the differences were not statistically significant. Conclusion : Positive thinking is likely to ameliorate major depressive disorder, panic disorder-induced depression, and anxiety. Nevertheless, it was not possible to confirm the effects of positive thinking on the patients' treatment responses.

In a flood of information, most users will want to get a proper recommendation. If a recommender system fails to give appropriate contents, then quality of experience (QoE) will be drastically decreased. In this paper, we propose a recommender system based on the intra-cluster users' item preference for improving recommendation accuracy indices such as precision, recall, and F1 score. To this end, first, users are divided into several clusters based on the actual rating data and Pearson correlation coefficient (PCC). Afterwards, we give each item an advantage/disadvantage according to the preference tendency by users within the same cluster. Specifically, an item will be received an advantage/disadvantage when the item which has been averagely rated by other users within the same cluster is above/below a predefined threshold. The proposed algorithm shows a statistically significant performance improvement over the item-based collaborative filtering algorithm with no clustering in terms of recommendation accuracy indices such as precision, recall, and F1 score.

Recently, consumers have shown an increasing tendency to seek information related to environmental, social, and governance (ESG) aspects in order to choose products with higher social value and environmental friendliness. In this paper, we proposes a product recommendation system applying ESG indicators tailored to the recent consumer trend of value-based consumption, utilizing a model called MultiSAGE that combines GraphSAGE and GAT. To achieve this, ESG rating data for 1,033 companies in 2022 collected from the Korea ESG Standard Institute and actual product data from N companies were transformed into a Heterogeneous Graph format through a data processing pipeline. The MultiSAGE model was then applied in machine learning to implement a recommendation system that, given a specific product, suggests eco-friendly alternatives. The implementation results indicate that consumers can easily compare and purchase products with ESG indicators applied, and it is anticipated that this system will be utilized in recommending products with social value and environmental friendliness.

Identifiable victim effect refers to the tendency of greater sympathy and helping behavior to identifiable victims than to abstract, unidentifiable ones. This research tested whether this tendency also affects third-party's punishment and compensation judgments in jury context for public's legal judgments. In addition, through the Identifiable victim effect in such legal judgment, we intended to explain the effect of 'the bill named for victim', putting the victim's real name and identity at the forefront, which is aimed at strengthening the punishment of related crimes by gaining public attention and support. To do so, we conducted experiments with hypothetical traffic accident scenarios that controlled legal components while manipulating victim's identifying information. In experiment 1, each participant read a scenario of an anonymous victim (unidentifiable condition) or a nonanonymous victim that included personal information such as name and age (identifiable condition) and made judgments on the degree of punishment and compensation. The results showed no effect of identifiability on third-party's punishment and compensation judgments, but moderation effect of BJW was obtained in the identifiable condition. That is, those with higher BJW showed greater tendency of punishment and compensation for identifiable victims. In Experiment 2, we compared an anonymous victim (unidentifiable condition) against a well-conducted victim (positive condition) and ill-conducted victim (negative condition) to test the effects of victim's characteristics on punishment for offender and compensation for victims. The results showed lower compensation for an ill-conducted victim than for an anonymous one. In addition, across all conditions except for negative condition, participants made punishment and compensation judgments higher than the average judicial precedents of 10-point presented in the rating scale. This research showed that victim's characteristics other than legal components affects third-party's legal decision making. Furthermore, we interpreted third-party's tendency to impose higher punishment and compensation with effect of 'the bill named for victim' and proposed social and legal discussion for and future research.

The authors studied obsession, using Derogatis'SCL-90, and lie tendency using MMPI, in the subjects of 2586 male and 1206 female college freshmen of Yeungnam University. The authors collected the reports of self-rating Obsession scale and Lie scale during the periods from January to February, 1988, and applied ANOVA and t-test on obsession and lie scores in order to compare than between various psychosocial factors, and sexes. The results as follows: 1. There was not significant difference in the mean average of total obsession scores between male and female students: male students scored $10.26{\pm}5.21$, female students scored $10.54{\pm}5.01$. 2. High scored items were doubting, indecisiveness, inattention, obsessive thoughts and preoccupation with accuracy. 3. 37 male students(1.4%) showed high obsession scores of 25 or higher, while 9 female students(0.7%) showed thd same scores. 4. There was strong tendency toward higher obsession scores in the students who were dissatisfied with their home atmosphere, college, department and familiarity of parents and those who had pessimistic view of self in the past, present or future in both group(respectively P<0.001). The male students who attended the department of fine arts, who grew at the Up & whose educational fees were paid by brothers & sisters showed higher level of obsession scores(respectively P<0.05, P<0.05, P<0.01). The female students who grew at the Myun & who were self-cook showed higher level of obsession scores(respectively P<0.05). 5. There was not significant difference in the mean averages of total lie scores between male and female students: male students scored $4.73{\pm}2.49$, female students scored $4.70{\pm}2.16$. 6. High scored items were NO. 14, 8, 11, 9 and 1 in the table 6. 7. 98 male students(3.7%) showed high lie scores of 70 or high, while 27 female students(2.2%) showed the same scores. 8. There was strong tendency toward higher lie scores in the students who were satisfied with their home atmosphere, college, department and familiarity of parents and those who had optimistic view of self in the past, present or future in both group(respectively P<0.001). The students who attended the department of pharmacy, music, evening programs showed higher level of lie scores(P<0.05).
