Purpose: This study examined the effects of manual lymph drainage (MLD) on edema and the quality of life (QOL) of lymphedema patients in the maintenance phase. Method: Forty five lymphedema patients, who had completed intensive decongestive therapy, were enrolled in this study. All subjects were assigned randomly to two groups: Experimental (MLD) group (n=23) and control (self-MLD) group (n=22). MLD by a specialist was applied with a comfortable pressure for 40~60 minutes in the experimental group and self-MLD was carried out by the control group 5 times a week for 2 weeks. The % edema and a SF-36 questionnaire were used to measure the decrease in edema and the QOL. A paired t-test was used to compare the period, and an independent T-test was used to compare experiment and control groups. Result: The % edema was significantly lower in the experimental group after MLD (p<0.05). The physical, vitality, and mental health scores of the experimental group was significantly higher than those of the control group (p<0.05). Conclusion: TMLD by a specialist in the maintenance phase is effective in reducing the % edema and enhancing the QOL of lymphedema patients. Further studies will be needed to determine if there are differences in the effects of many types of treatment methods in the lymphedema treatment.

Purpose: The purpose of this study was to investigate the effect of the moderate drinking program based on social cognitive theory on changes in the drinking habits of college students with drinking problems. Methods: This study included a total of 68 college students with drinking problems. These participants participated in 10 sessions of a moderate drinking program in which social cognitive theory was applied. Changes in the cognition and behaviors of the participants were then investigated. Results: The moderate drinking program based on social cognitive theory for college students with drinking problems was effective in increasing the subjects' drinking-related knowledge (U=191.50, p<.001), enhancing their drinking refusal self-efficacy(t=8.02, p<.001), and changing their drinking-related attitudes (U=108.50, p<.001), drinking outcome expectancy (t=8.68, p<.001), amount of drinking in a single session ($x^2=25.72$, p<.001), number of drinking sessions per month ($x^2=10.05$, p=.006), and problem drinking behaviors (t=5.77, p<.001). Conclusion: These results can be used to inform a regular on-campus intervention programs for moderate drinking, and to implement education about moderate drinking, thereby increasing the success rate of drinking reduction.

Kyung-Ok-Go (KOK) is a traditional prescription used for debilitating natural aging and post-illness debilitation. KOK has been used in a variety of ways because it strengthens immunity, prevents illness, and helps recovery in case of illness. In particular, recent research has revealed that KOK helps improve memory and cognition. Therefore, in this study, we investigated whether KOK was effective in improving memory decline and depression-state observed during menopause. In the present study, we employed ovariectomized mouse as an animal model for measuring menopausal syndrome. The administration of KOK for 8 weeks, the object recognition memory and working memory were improved in novel object recognition test and Y-maze test. And in the forced swimming test, the immobility time were decreased. Additionally, the expression level of mature brain derived neurotropic factor (mBDNF) was increased by KOK administration in ovariectomized mouse hippocampus. These results suggested that KOK could improve cognitive decline and depression during menopausal period, and it might be come from enhancing expression level of mBDNF in hippocampus.

The coordination and control of construction projects is vital if a project is to be a success. Almost all analysis has shown that these can only be achieved if good quality communication can be maintained on a construction site. This research focuses on the role that tablet computers could play in enhancing this communication. The following points are investigated in this paper: (a) Whether a tablet computer can enable users to monitor project progress more efficiently than traditional methods, (b) How the tablet computer fits within the project management iron triangle in construction, (c) The two different psychological impacts of information transmission for the end user using a tablet computer (i) The expectancy to transmit information frequently and rapidly from tablet computer users to project members whilst working onsite (ii) The mode of information transmission to the cognition of the transmitted information to the tablet computer. Through the use of structured interviews and questionnaires, the opinions of individuals within various disciplines in construction were canvassed. The approach adopted in this paper deals with understanding both the soft and hard issues for deploying such a system. This research enabled the authors to develop a base framework incorporating the key factors which are relevant for implementing a tablet computer based on information flows primarily.

The purpose of this review is to provide a comprehensive analysis of the intricate relationships between cognitive control, depression, and emotion regulation. Cognitive control, encompassing processes such as attentional control, inhibitory control, and cognitive flexibility, plays a central role in regulating thoughts, behaviors, and emotions in alignment with internal goals and external demands. Depression, characterized by persistent feelings of sadness, hopelessness, and cognitive impairments, is associated with deficits in cognitive control processes. Emotion regulation strategies, such as cognitive reappraisal and expressive suppression, enable individuals to modulate emotional experiences and responses. The bidirectional relationships between cognitive control, depression, and emotion regulation underscore the complexity of cognitive and emotional processes in depression. Understanding these relationships is crucial for developing targeted interventions aimed at promoting cognitive and emotional well-being and preventing depression onset and recurrence. Moreover, recognizing the roles of cognitive control and emotion regulation in depression holds promise for informing clinical practice and enhancing therapeutic interventions. This review highlights the importance of considering cognitive control and emotion regulation in the assessment and treatment of depression and provides insights for future research and clinical practice.

Purpose: This study investigates the psychological mechanisms of comparison within the design context of retail stores, products, and advertising. The research aims to expand the understanding of comparison psychology, encompassing social, cognitive, perceptual, and self-comparisons and their application in design practices. Research Design, Data, and Methodology: The study employs a comprehensive review of psychological theories related to comparison psychology. They were selected through extensive research on literature pertaining to design psychology and consumer behavior. The research integrates insights from psychology, marketing, consumer behavior, and design theory, supported by various design examples of retail stores, products, and advertising, to demonstrate the practical applications. Results: The findings reveal that comparison psychology significantly impacts consumer preferences and user experiences. For instance, the assimilation effect and prospect theory highlight how comparisons shape value judgments and design perceptions. Practical examples are used to illustrate the profound influence of comparative judgments in design. Conclusion: The study advocates for a "psychologically-informed approach" to design, promoting designs that are not only aesthetically pleasing and functionally sound but also psychologically aligned. By bridging the gap between psychological theories and practical design implementations, the research provides valuable insights for designers, marketers, and psychologists, enhancing the psychological efficacy of design.

Korea has continuously increased investment on R&D to improve global technology competitiveness through technology innovation. Korea's R&D expenditure as a percent of GDP is world's No. 1 as 4.15 and it accomplished 1 trillion won trade volume for 4 consecutive years. However, despite these efforts, technology balance of payment, which is an important factor that can measure nation's technology competitiveness is in a state of chronic deficit and the lowest level among OECD countries. In this paper, we studied methods to improve Korea's technology balance of payment We figured out concept and current state of technology trade and examined the importance of technology trade through making a comparison between commodity trade and technology trade. There have been studies regarding technology trade, but there was no study which tried to figure out cognition on technology trade from the point of view of companies which plays an important role in technology trade. For this, this study distinguished companies with experience in technology trade and which have not and conducted a survey to figure out cognition and current state of companies. The survey result showed noticeable difference on cognition of top decision makers between companies with experience in technology trade and which have not and there are serious shortage in department and staff which is exclusively responsible for technology trade. Also, despite their needs for education regarding technology trade, the ratio of employees who received education is below 10 % of the total respondents. This study suggested improvement methods such as reforming survey methods of technology trade statistics, enhancing social cognition, supporting to vitalize technology export, building infrastructure regarding technology trade, and opening education programs for cultivating experts based on preceding research and industry survey.

Objectives The eye movement (EM) has been reported to play a role in enhancing the retrieval of episodic memories and reducing effects of fearful episodes in the past and worries for the futures. However, it is still unclear in the mechanism of EM in normal subjects. We examined the horizontal eye movement (HEM) effect using an aiding apparatus on mental health indices including negative and positive psychological factors, and psychophysiological measures such as heart rate variability and quantitative electroencepaholography (qEEG) in healthy subjects. Methods Twenty eight healthy subjects were recruited and randomly allocated into two groups : active HEM group and control group. The active HEM group conducted the HEM training with usual stress management audio-intervention using the apparatus inducing eye movement once a day for 14 days. The control group also conducted the same training once a day for 14 days, however, the saccadic eye movement was not included in this training. Psychological measurements, neurocognitive function tests, heart rate variability measurement and qEEG were conducted before and after the training in both groups. Results In the active HEM group, sleep status using Sleep Quality Scale (SQS) positive factors significantly increased after the training. By contrast, scores on the negative items of Psychological Well-Being Scale (PWBS), and negative items of the Life Orientation Test-Revised (LOT-R) were significantly decreased after the training. The percentage of delta amplitude (1-3 Hz) in qEEG significantly decreased after the HEM training. The percentage of alpha amplitude (8-12 Hz) significantly increased after HEM training. The change of delta amplitude in the active HEM group was positively correlated with the change of sleep satisfaction of Visual Analogue Scale (VAS), and the change of alpha amplitude was negatively correlated with depression of VAS, anxiety of VAS and Beck Anxiety Inventory (BAI). Conclusions The HEM training improved sleep quality and well-being, and sense of optimism. The HEM training also increased alpha amplitude and decreased delta amplitude in qEEG. The qEEG changes were well correlated with subjective improvement of mental health indices in healthy subjects. These results suggest some evidences that HEM training using the apparatus that induces EM would be helpful in improving subjective mental health in healthy subjects. Further study with larger samples size would be needed.

Although it is widely acknowledged that enhancing creativity is an important educational theme on which schools should depend and embody their educational goal and activities, how to do it can be characterized as 'piecemeal' without a whole picture of it. Thus, school practices of creativity education has been disoriented, discontinuous, short-term, and peripheral in nature. In this practical context, a theoretical model of creativity education was developed in ways in which several theoretical concepts based on research findings on a variety of aspects of creativity education were compiled and organized. The core of the model was creative problem solving process to which the goals and the mediating variables of creativity education were connected in relational fashion. By giving repetitive opportunities for creative problem solving geared to producing the results that are novel and useful for the individual as well as the socity, it was conceptualized that two educational goals could be achieved: a short-term goal of developing creative potential of the individual and the long-term goals of self-actualization of the individual and contribution to the society. It is also conceptualized that creative problem solving can be influenced in positive manner by several mediating variables: content knowledge and skills, creative cognition, creative motivation and attitudes, and creative environment. The creative environment is composed of psychological and physical conditions and provides a basis for creativity education. The former three variables are conceptualized as necessary conditions for the effectiveness and efficiency of creative problem solving, when provided appropriately. The four mediating variables ware conceptualized as mutually affecting so that the development of one variable influences positively that of the other, and vice versa. In terms of practical perspective of teaching creativity, developing creative potential, self-actualization, and contribution to society are the goals; creative problem solving process is the methodology; content knowledge and skills, creative cognition, and creative motivation and attitudes are the content; and creative environment is the condition of creativity education. The model is not yet perfect but needs further explorations to make it more detailed in clarifying various relationships. For instance, how the creative problem solving process can be differentiated in teaching various subject matters is yet to be explored. Thus, the model proposed in this study should be regarded as a general model of creativity education, and is relatively sound to be adopted in school practices since it is based on the theoretical as well as empirical study findings on creativity. However, the proposed model needs to be validated through empirical researches in real teaching settings.

Objectives : This research was performed to investigate the effects of Hwangryunhaedok-tang decoction and Hwangryunhaedok-tang Pharmacopuncture at BL10 on cognition and memory impairment in a mouse dementia model induced by scopolamine. Methods : Fifty ICR mice were divided into 6 groups : Normal group (n=5), Control group (n=9), Positive control group for pharmacopuncture group (n=9, Donepezil 0.75 mg/kg), Positive control group for oral administration group (n=9, Donepezil 5 mg/kg), Pharmacopuncture group (n=9, Hwangryunhaedok-tang Pharmacopuncture undiluted solution 10 ml/kg), and Oral administration group (n=9, Hwangryunhaedok-tang 200 mg/kg). For a mouse dementia model, 1 mg/kg scopolamine was intraperitoneally administered to ICR mice. Hwangryunhaedok-tang pharmacopuncture was administered on BL10 for 4 weeks at intervals of 2 days. Hwangryunhaedok-tang decoction was given orally for 4 weeks every day. Morris water maze and passive avoidance test were conducted followed by measurement of acetylcholine concentration, acetylcholinesterase activity, and the amount of BDNF and p-CREB in the brain. Results : 1. In the Morris water maze test, the time spent staying around the platform significantly increased in the pharmacopuncture group and oral administration group than in the control group. 2. In the passive avoidance test, the time spent in the bright room significantly increased in the pharmacopuncture group and oral administration group than in the control group. 3. The level of acetylcholine in brains increased in the pharmacopuncture group and oral administration group than in the control group. Also, the activity of acetylcholinesterase decreased in the pharmacopuncture group and oral administration group than in the control group. 4. The expression of BDNF and p-CREB decreased in the control group, but increased in the pharmacopuncture group and oral administration group. Conclusions : These results suggest that Hwangryunhaedok-tang decoction and Hwangryunhaedok-tang pharmacopuncture at BL10 may have cognition and memory-enhancing effect in scopolamine-induced dementia in ICR mice via controlling the content of acetylcholine and the activity of acetylcholinesterase, and activating BDNF and p-CREB.
