We know that humans are able to live comfortably when there is a balance between the living environment that surrounds us and us. Clothing, one of the necessities of life, serves a dual purpose of functioning as protection for the body as well as providing visual satisfaction, and so is the most effective bonding mechanism. A different type of comfort that has been provided through industrialization and advancements in technology has resulted in pollution problems in the environment, and it has reached a point of seriously thinking about its effects. The biggest problems in environmental pollution are air pollution and waste disposal, and something that cannot be ignored is that environmental hormones and harmful heavy metals have been discovered in the synthetic dyes used in the clothing product, and not only are they harmful to the body, but they also have adverse effects on skin allergies such as atopic dermatitis. Its effects on clothing, especially underwear and baby products, can become a serious issue. The use of natural vegetable dye can be considered the basis for the traditional Korean dyeing process, however not all natural dyeing process can be thought of as traditional Korean dyeing. This is because natural dyeing used to be the most common method of dyeing before synthetic dyes came along and became the dye of choice for most clothing. Natural dyes are beneficial to the body, and the nature colors, achieved from the natural materials, relieve eye strains as well as have a healing effect for people who are suffering from psychological instability such as stress. However, the use of mordant in order to increase the fastness and get better color effects can lead to even more damage to the environment, and it cannot be a dyeing method that is good for the body. Traditional natural dyeing is different from regular natural dyeing because it uses colors that the Korean people can identify with and applies specific methods in order to achieve those colors. Even though experimental study with dyestuff and practical use of the dyeing methods for traditional Korean dyeing has been started(Soh, H., 1983) and has been ongoing, it is still not easy for regular people to use the method on their own. At the present time, natural dye materials are getting made and sold more than ever, but there is a lot of confusion among consumers regarding the difference between traditional Korean dyeing and natural dyeing, as companies are using the two terms interchangeably to market their natural dye products. So getting a better understanding of the characteristics of traditional Korean dyeing and traditional colors should be considered first priority at this time. The purpose of this thesis is to study the traditional Korean view of color, which developed the culture of traditional dyeing in Korea, and the characteristics of traditional Korean dyeing, a method that pursued achieving Korea's color through natural dyeing.

Purpose : The acupuncture existed more than 2000 years and has flourished not only in Asia but also in medical field of modern world. In addition, empirical evidences from biomedicine have been expended in many ways in order to objectify the field of acupuncture. Thus, the effect and mechanism of the acupuncture has been revealed in human and other animals. In this article, I attempt to explain what doctors and patients subjectively experience through acupuncture treatment and its clinical significance based on mind-body medicine. Methods : The experience and clinical significance of the acupuncture was examined in the view of mind-body medicine, also reviewed research trends related to meditation understanding the clinical effectiveness of acupuncture. Results and Conclusions : Traditional Korean medical doctor perceive generally "jogi " and "chishin " meaning the regulation of the balance of the various functions in the human body and patient's consciousness and psychology state as mightily important concept concerning the therapeutic effect of acupuncture. Despite scientific approach to objective understanding of the acupuncture was performed in the meantime, practitioners put emphasis on experience based on sensate and interaction between doctor-patient. As it reflects the recent understanding of the psychological effects associated with the clinical efficacy of acupuncture, it has been presented one by one through neuroscience and cognitive science. Therefore it is important that interpreting the clinical effectiveness of acupuncture into Mind-body medicine can form a new awareness and attitudes toward traditional medicine.

Traumatic Brain Injury(TBI) of any severity can result in broad and persisting biopsychosocial sequelae. Depression after TBI occur at a greater frequency than in the general population, with estimates approaching 25% to 50% for major depression, and 155 to 30% for dysthmia. Acute onset depressions are related to lesion location and may have their etiology in biological response of the injured brain, whereas delayed onset depressions may be mediated by psychosocial factors, suggesting psychological reactions as a possible mechanism. Anxious depressions are associated with right hemisphere lesions, whereas major depressions alone are associated with left dorsolateral frontal and left basal ganglia lesions. However, there is insufficient information to postulate a specific neuroanatomic model for TBI-related depression.

Due to its well-known function in parturition and milk ejection, oxytocin (OT) has been considered as a 'female neurohypophyseal hormone'. Recent studies, however, clearly indicate that OT has some local roles in male reproduction via both central and peripheral routes. In experimental rodents, OT is released within distinct brain regions in response to social stimuli, and the brain OT receptor (OTR) mediated actions were strongly involved in the regulation of a variety of male behaviors such as mating-associated behaviors. In particular, OT and/or OTR knockout mice provide important clues about the molecular regulatory mechanism of the socio-sexual behaviors. Several lines of evidence also show that OT is synthesized within rodents testis, epididymis and prostate, and the presence of OTRs in these organs. In rodent testes, OT might have a role in the modulation of steroidogenesis via stimulation of the conversion of testosterone (T) to dihydrotestosterone (DHT) by 5alpha-reductase. Similar effects of OT on this androgen conversion were observed in epididymis and prostate suggesting the OT's modulatory role, such as contractility induction, in these androgen-dependent organs. In this context, further investigations on the OT's role in male CNS and reproductive organs are likely to provide better understanding on the complex socio-sexual behaviors and a platform for development of therapeutics to treat some psychological and/or andrological problems.

A majority of past studies have tried to investigate cigarette consumption in terms of smoker's cognitive aspects. However, smokers may experience feelings of guilt as a negative emotion while satisfying hedonic and social motive via cigarette consumption. Particularly, feelings of guilt associated with smoking may be induced when smokers' cigarette consumption contradicts their ideal self-concept or social self-concept. The research thus studied smoker's psychological mechanism, focusing on feelings of guilt associated with cigarette consumption. The results indicated that as smokers perceived physical harm associated with their cigarette consumption more than hedonic benefits from the cigarette consumption, they were more likely to experience feelings of guilt related to themselves and others. As smokers perceived social images of smoker as more negative, they were more likely to experience feelings of guilt related to others. Lastly, smokers' experiencing feelings of guilt related to themselves and others had a positive effect on smoking cessation intent. The research findings suggest that the anti-smoking campaign inducing guilt related to smokers' themselves (e.g., raising the price of cigarettes) and others (e.g., anti-smoking ads displaying physical damage of secondhand smoke on family members) can increase smokers' cessation intent.

This study examined the perception of disasters and post-traumatic stress disorder in occupational therapy majors to provide the basic data necessary for future occupational therapy. A questionnaire survey was conducted on 545 students in occupational therapy departments of three year and four year universities. The frequency of the questionnaire was calculated by frequency analysis using the SPSS 19.0 win program. A chi-squared test was conducted to verify the analyzed questionnaire data. The reliability of the questionnaire in this study showed a Cronbach' alpha value of 0.891. According to the survey results, approximately 20% of learners who majored in occupational therapy were unaware of the symptoms, developmental mechanism, and diagnostic criteria of post-traumatic stress disorder(PTSD). Knowledge of the underlying causes of psychological symptoms, such as post-traumatic stress disorder as well as physical damage through industrial accidents, was found to be 2.92 on the Likert 5-point scale. To be effective in rehabilitation treatment, the degree of the approach to education from the viewpoint of occupational therapy is important enough to be recognized as 3.90 on the Likert 5-point scale. The Pearson correlation coefficient for the need for education on disasters was higher than the correlation with the awareness of disasters.

Objectives : Insomnia may be one of the risk factor for suicidal ideation, but little is known about the mechanism by which sleep disturbances confer risk for suicide. The aim of this study was to investigate examine whether insomnia severity would be associated with resilience and suicidal ideation, and whether resilience would mediate the relationship between insomnia and suicidal ideation. Methods : A total of 432 community-dwelling adults(227 male, 205 female,) completed the self-report questionnaire that covered basic socio-demographic data. To assess the psychological variables, the following instruments were applied: Insomnia Severity Index(ISI), Korean Version of the Connor-Davidson Resilience Scale(K-CD-RISC), Beck Hopelessness Scale(BHOP) and Scale for Suicidal Ideation(SSI-Beck). People with an ISI score of 8 or higher were defined as insomnia. Results : Greater insomnia symptom severity was significantly associated with higher level of suicidal ideation and lower level of resilience, adjusting for hopelessness, age, sex, presence of family members living together, and household income. Additional analysis revealed that disturbance of sleep initiation and disturbance of sleep maintenance were significantly associated with suicidal ideation. Mediation analyses revealed that resilience significantly accounted for the relationship between insomnia symptom severity and suicidal ideation. Conclusions : These findings suggest that the evaluation and control of insomnia and resilience may be needed to reduce the risk of suicide.

Objective: The aim of this study is to investigate 1) somatotopic arrangement of the second and third fingers in SI area 2) difference of neural activation in the SI area produced by stimulation with different frequencies 3) correlation between the intensity of tactile perception by different stimulus intensity and the level of brain activation measurable by means of fMRI. Background: Somatosensory cortex can obtain the information of environmental stimuli about "where" (e.g., on the left palm), "what" (e.g., a book or a dog), and "how" (e.g., scrub gently or scrub roughly) to organism. However, compared to visual sense, the neural mechanism underlying the processing of specific electrotactile stimulus is still unknown. Method: 10 right-handed subjects participated in this study. Non-painful electrotactile stimuli were delivered to two different finger tips of right hand. Functional brain images were collected from 3.0T MRI using the single-shot EPI method. The scanning parameters were as follows: TR and TE were 3000, 35ms, respectively, flip angle 60, FOV $24{\times}24cm$, matrix size $64{\times}64$, slice thickness 4mm (no gap). SPM5 was used to analyze the fMRI data. Results: Significant activations produced by the stimulation were found in the SI, SII, the subcentral gyrus, the precentral gyrus, and the insula. In all participants, statistically significant activation was observed in the contralateral SI area and the bilateral SII areas by the stimulation on the fingers but ipsilaterally dominant. The SI area representing the second finger generally located in the more lateral and inferior side than that of the third finger across all the subjects. But no difference in brain area was found for the stimulation of the fingers by different frequencies. And two typical patterns were observed on the relationship between the perceived psychological intensity and the amount of voxels in the primary sensory cortex during the stimulation. Conclusion: It was possible to discriminate the representation sites in the SI by electrotactile stimulation of digit2 and digit3. But we could not find the differences of the brain areas according to different stimulation frequencies from 3 to 300Hz. Application: The results of the study can provide a deeper understanding of somatosensory cortex and offer the information for tactile display for blinds.

Cleidocranial dysplasia(CCD) is a congenital disorder of skeletal and dental abnormality, which is mesodermal dysfunction influencing many tissues and organs. Skeletal abnormalities in CCD are delayed closure of cranial suture and fontanelle, presence of wormian bone and clavicle aplasia. And CCD has an effect on the long bones, phalanges, spine, pelvis, muscles, and central nervous system. Dental manifestations include retention of deciduous teeth, multiple supernumerary teeth, delayed or absent eruption of permanent teeth and formation of cysts around nonerupted teeth. But as a result in common with a lack of medical and physical disability patient may have no substantive complaint, there are many masticatory and psychological problem by absent eruption of permanent teeth after exfoliation of deciduous teeth. For this reason CCD is necessary fo early diagnosis and must be improvement of the patient's appearance as well as provision of a functioning masticatory mechanism by treatment of surgical removal of supernumerary teeth, followed orthodontically eruption of the natural permanent teeth at adequate time.

Cleidocranial dysplasia(CCD) is a congenital disorder of skeletal and dental abnormality, which is a mesodermal dysfunction influencing many tisssues and organs. Skeletal abnormalities in CCD are delayed closure of cranial suture and fontanelle, presence of wormian bone and clavicle aplasia. CCD also has an effect on long bones, phalanges, spine, pelvis, muscles, and central nervous system. Dental manifestations include retention of deciduous teeth, multiple supernumerary teeth, delayed eruption or impaction of permanent teeth and formation of cysts around nonerupted teeth. However, due to lack of any substansive medical or physical disability, diagnosis is often late, thereby causing masticatory and psychological problems caused by delayed eruption of permanent teeth after exfoliation of deciduous teeth. For this reason, CCD requires early diagnosis, and the patient's appearance must be improved. Also, provision for a functional masticatiory mechanism by treatment of surgical removal of supernumerary teeth followed by orthodontic eruption of the natural permanent teeth at an adequate time is necessary.
