In these days, wearable and mobile physiological sensing devices have been studied according to the increasing interest on the healthy and wellbeing life. However, these sensing devices display just the sensing results, such as heart rate, skin temperature, and its daily records. In this work, we propose the novel type of mobile physiological sensing device which deliver the user comfortable grabbing feeling. In addition, we indicate the personalized physiological signal analysis result which be concluded by the different analysis results according to the person to person. In order to verify this sensing device, we collect the data set from 4 different users during a week and measure the physiological signal such as heart rate, hand temperature, and skin conductance. And we observe the result how the analysis results shows the difference between the users. We expect that this work can be applied in the various health care applications in the near future.

Symbiodinium is a dinoflagellate genus that coexists with coral reefs and is known to provide ultraviolet (UV) protection in nature through the synthesis of mycosporin-like amino acids (MAA). In order to develop a natural and ecofriendly sunblock for use in summer resorts, the possibility of using a Symbiodinium microbiome extract or an MAA was investigated. Two sunblocks, one containing 7% Symbiodinium extract and the other containing MAA were prepared to be tested on hairless mice and human skin. In this clinical study, the sun protection factor (SPF) and Protection factor of UV A (PFA) values of the sunblock containing either Symbiodinium extract or MAA were determined. The SPF values of the sunblock containing Symbiodinium extract and MAA were 10.43 and 10.83, respectively, and the PFA values were 3.42 and 3.39, respectively. Based on their PFA values of ≥2, the UV A protection can be graded as PA+ (low) for both the sunblocks. In addition, the UV-blocking extract of Symbiodinium has a low phototoxicity and cytotoxicity, reducing the possibility of a heavy feeling to the skin or a foreign-body sensation caused by residue build-up. The low toxicity feature of the major sunblock component will also prevent side effects, such as allergic reactions. Although Symbiodinium extract or MAA alone do not provide effectiveprotection against UV irradiation, their protection capacity can be complemented by the addition of inorganic UV-protecting compounds.

Wearing a clothes in human living is very rightful and reasonable things. And it's also the necessaries of living. So now, I want look around about origin of clothes from the prehistorical age, how they start and why they need to wear a clothes. As human culture is unknown origin, human clothes origin is also unknown origin, too. So many different people made unlike story about that, and it is very difficult to say correct birth of clothes. It must be reflection by a time, by a place, by a mankind, until this days, the history of human progress is $2,000,000{\sim}3,000,000$ years. And from after the "Old Adam" man understand what is shame and disgrace, so that made them cover of their private parts, also it is a motive of human clothes. Since after pass a long time, the earth has many changes as it were weather, and for take care of human body from cold, people start make clothes and it's a second object of wearing a clothes. And third object of wearing clothes is after opportunity of development human culture, people desire for an aesthetic sence and for full-fill that feeling they start make a beautiful clothes with accessories and it is motive and a purpose of a human start wear a clothes. So I can say, for origin birth of clothes is 1. Protect of human body. 1) be adapted for different weather and different circumstance. 2) take care self from outside injurg. 2. Decorate for aesthetic sence. 1) Theory of Amulets. 2) Theory of symbolism. 3) Theory of Sex attraction. 4) Aesthetic Theory. 5) Theory of chastity. 6) Multi-theory And material for clothes they made from natural wilds like leaves, fur, skin of wood. skin of fishes and feather etc. But after develop of human knowledge people invent fiber, and use a knitted goods and woven stuff also first of all. They start use those kind that they just cover of their private parts as a belt and astring with leaves and a beast skins. But until this days it's taken big development with human knowledge and most important influence of develop was weather. So modern clothes for present days, must care with. physicology, preservation of health, living activity, dressing, morals, and etiquette etc.

The corpse make-up depending on the cause of death shown in CSI is the only evidence to solve a case, and shows the characteristics of the unique make-up on the corpse, according to the causes of death. There are many types of death causes such as strangulation, manslaughter, assassination and shooting, of which the strangulation is caused by strangling the neck with the hands or using a weapon and has characteristics of showing other external wounds with purple spots appearing on the body after death. This is a presentation of the corpse with a face of white, and the purple spots bruised on the neck. Manslaughter shows deep wounds caused by a stab or laceration using a weapon, and the material feeling of the wound that makes new skin tissue, is realistically presented with make-up of gooey blood. Assassination can be thought as manslaughter in disguise as an accidental death, which the causes can be due to electrocution, suffocation from oxygen deficiency and from excessive monoxide. The make-up is presented by realistically showing the surrounding fragments of the bullet shell, the blood running down, the size of the hole in the body made from the bullet, and shows the broken skin tissues. The shape of the bullet wound can be presented differently based on the body part where the bullet penetrated into, and the part where the bullet shot out through.

Depression is a psychiatric syndrom consisting of dejected mood, psychomotor retardation, insomnia and weight loss, sometimes associated with irrational guilt feeling. And it is also similiar to Hwa-byung(火病) symptom in oriental medicine. But it is difficult to diagnose with objective method. Digital Infrared Thermographic Imaging(D.I.T.I.) is one of diagnotic method that measure the changes of skin temperature in body. Specially we checked the skin temperature on depressed patients by using D.I.T.I. and compared with Bell's palsy patients and normal persons group. The results are as follows; Average body temperature of the depressed patient group is $36.68{\pm}0.43^{\circ}C.$ and that of the control group is $36.73{\pm}0.40^{\circ}C.$. So there is no meaningful difference. The depressed patient group has higher temperature than the control group by ${\triangle}T>1.0^{\circ}C$ at the following acupuncture points in these body parts - upper and lower, left and right, anterior and posterior. When acupuncture points temperature was compared superior and inferior part of the body, depressed patient group have meaningful difference at the GV-4(Myung-moon) and also in the control group. When acupuncture points temperature was compared left and right part of the body, depressed patient group have no meaningful difference and also in the control group. When acupuncture points temperature was compared in the anterior and posterior part of the body, depressed patient group have meaningful difference at the GV-4(Myung- moon) and also in the control group. From this study, we think that D.I.T.I. could be used to diagnose objectively on the depressed patients and useful to another psychoneurogenic diagnosis in oriental medicine.

The purpose of this study is to weigh the students' backpacks of middle school in daily use and to analyse their physiological responses and subjective senses when carrying backpack in order to promote healthy and comfort school life of girl middle school students. Two female students were subjects who answered the questionnaires on two types of backpack and their metabolism, perspiration and the changes of skin temperature were measured in constant environment chamber, $25{\pm}1$ and $49{\pm}10$% RH. They walked on the treadmill carrying the backpack with the increment of backpack weight, 2 kg, 4 kg to 6 kg. When the backpack increases to 6 kg, the discomfort parameters and responses increases rapidly. Comparing with general type, improved type of backpack showed good results in physiological responses, but not in subjective senses, such as the ease of movement, pain, or total preference, specially in 2 kg and 4 kg. The girl students prefer the general type of backpack which is of fashion and small, when it weighs light such as 2 kg or 4 kg, while they prefer the improved bag which is functional when it is heavy as 6 kg. The longer wearing time of the medium weight, for example, 4 kg without feeling or recognition of any discomfort due to fashion style, might cause the students' posture and health weaker or more vulnerable to the problems.

Objectives: This work aimed to investigate differentiations of Korean medicine's pathological symptoms and SF-12 sub scales among normal, overweight and obese subjects from multi-center case report. Methods: From 2009 to 2011 survey were carried out to 1,589 subjects who took treatment or were hospitalized in 7 Korean medicine hospitals and 3 Korean medicine clinic. Survey include Korean medicine's pathological symptoms and SF-12. Whole survey were obtained from subjects with interviewers. Obesity degree was divided into three groups by body mass index: Normal group is from 18.5 below 23, overweight from 23 below 25 and obese group is over 25. Chi-square test was performed to reveal differentiation response rate of pathologic symptoms among obesity groups. ANOVA test was carried out for compare each group's SF-12 sub scales. Results: Patients of overweight or obesity have more symptoms such as skin itching, swelling, weakness in lower legs, and feverish with swollen joints. Contrary, normal weight group responded symptoms of dry skin more than those of obese group. As a fatigue, obese group have more fatigue feeling at afternoon and evening, compared to high frequency response of normal weight groups' morning fatigue. Obese groups shows low physical scores of health related quality of life, in contrast, high mental scores of that. Conclusions: This is first work of pathologic symptoms shown by obese groups. This would contribute to standardization of Korean medicine's pattern identification as suggestion of classification point for obese groups.

Purpose: This study was done to develop data for a hygiene promotion program for elders living on rural islands. Method: Self-administered questionnaires were used to collect data. Results: Most of the elders reported brushed their teeth and washing their faces twice a day. For other types of washing, 98.8% of reported washing their hands after the toilet and 22.8% reported washing their anus after defecation. Most of the elders reported changing their underwear two to three times a month and cutting their nails more than four times a month. Itchiness was reported by 24%. There were significant differences according to age for teeth brushing, face washing, shampooing, bathing, washing hands after the toilet, and cutting nails. According to sex, there were significant differences in teeth brushing, face washing, washing hands after using the toilet, washing anus after defecation, changing underwear, cutting nails, and feeling itchy. The elders showed significant differences in bathing, changing underwear, and cutting nails according to subjective economic status. They showed significant differences in teeth brushing and changing underwear when they lived with their families. Conclusion: In order to develop a proper hygiene promotion program for the elderly, their age, sex, and physical condition should be considered as well as their environmental, economical, and geographical condition.

Purpose: To report the results and the efficacy of the sensory bearing scapular free flap which is known as non-sensible flap. Materials and Methods: Authors underwent 24 cases of sensory bearing scapular free flap to the hands and feet from March 1995 to November 2002. average follow-up period was six year three months. The used flaps were a ordinary scapular flap in fifteen cases, and a parascapular flap in nine. Sensibility of the flaps were checked every one month. Actual sensory evaluation was mostly depends on objective feeling of the patients. Two point discrimination test was performed in all cases. Results: 23 flaps had good skin circulation after microvascular anastomosis among 24. Objective deep touch sensation were observed about three months later after the operation in three cases, between three and six months in nine. In three case whose results were excellent than others, two point discrimination was 2.7 cm at last follow-up. Most of the sensory recovery is confined in deep touch, temperature and light touch sensation was recovered limitedly in 3 cases during our follow-up period. Conclusion: Authors can propose that sensory bearing free scapular flap was considered as one of useful methods for the reconstruction to hand with soft tissue defect and mutilating hand.

In this study, the effect of wearing functional compression pants is verified using a lower-limb wearable robot through a bio-signal analysis and subjective fit evaluation. First, the compression area to be applied to the functional compression pants is derived using the quad method for nine men in their 20s. Subsequently, functional compression pants are prepared, and changes in Electroencephalogram (EEG) and Electrocardiogram (ECG) signals when wearing the functional compression and normal regular pants inside a wearable robot are measured. The EEG and ECG signals are measured with eyes closed and open. Results indicate that the Relative alpha (RA) and Relative gamma wave (RG) of the EEG signal differ significantly, resulting in increased stability and reduced anxiety and stress when wearing the functional compression pants. Furthermore, the ECG analysis results indicate statistically significant differences in the Low frequency (LF)/High frequency (HF) index, which reflect the overall balance of the autonomic nervous system and can be interpreted as feeling comfortable and balanced when wearing the functional compression pants. Moreover, subjective sense is discovered to be effective in assessing wear fit, ease of movement, skin friction, and wear comfort when wearing the functional compression pants.
