This study intends to analyze T-shirt designs, particularly in connection with pop art. 444 pieces of T-shirts which conveyed the pop art spirits of well-known designers were selected for five years from 2001 to 2005, through fashion magazines(Collection: Dong-ah TV, Collezioni: Italy). The findings are as follows. As for formative characteristics of pop art in T-shirts, previous studies were analyzed to set classifications criteria such as popularization of images, eroticism, lettering and graffiti, assemblage. The design factor of the image popularization includes everyday images, cartoon, celebrities, and caricature. Everyday images ranked first followed by cartoon, caricature and celebrities. The design factor of eroticism ranges from the see-through look, partial exposure of human body, symbolization of underwear, and to printing of sexy images. The see-through look was ranked first, followed by partial exposure of human body, symbolization of underwear, and printing of sexy images. The design factor of lettering and graffiti encompasses letters, numbers, symbols and logos. Adoption of letters, numbers or symbols was ranked first, followed by brand logos and graffiti. The design factor of Assemblage is closely related to a three-dimensional effect. Varied expressions are possible: combination of two different textiles and fusion of textile and non-textile. Combination of two different textiles are higher than fusion of textile and non-textile.

A thick 25 ${\mu}m$ thickness poled P(VDF/TrFE) film pyroelectric infrared ray sensor has been fabricated and then thin 1.6 ${\mu}m$ thickness P(VDF/TrFE) film pyroelectric infrared ray sensor has been fabricated also. These thick and thin P(VDF/TrFE) film pyroelectric infrared ray sensor was mounted in TO-5 housing to detect infrared light of 5.5 ~ 14 ${\mu}m$ wavelength for human body detecting with each other. The noise output voltage of the thick P(VDF/TrFE) film pyroelectric infrared ray sensor were 380 mV and NEP(noise equivalent power) is $3.95{\times}10^{-7}$ W which is the similar value with the commercial pyroelectric infrared ray sensor using ceramic materials as a sensing material. The NEP and specific detectivity $D^*$ of the thin P(VDF/TrFE) film pyroelectric infrared ray sensor were $2.13{\times}10^{-8}$ W and $9.37{\times}106$ cm/W under emission energy of 13 ${\mu}W/cm^2$ respectively. These result caused by lower thermal diffusion coefficient of a thin 1.6 ${\mu}m$ thickness PVDF/TrFE film than the thick 25 ${\mu}m$ thickness poled P(VDF/TrFE) film pyroelectric infrared ray sensor.

최근 문학치료에 대한 관심이 높아지고 있다. 그렇지만 독서치료를 문학치료라고 하는 경우도 있다. 그러나 문학치료사라 하려면 문학 텍스트가 전해주는 감정에 대해서 알아야 한다. 이를 위해 박인과는 오랫동안 인체가 발화하는 문장들과 감정들의 관계를 연구해 왔다. 이 연구도 이와 같이 인체가 문학적 텍스트에 의해 감정을 발화하고 치유된다는 관점에서 이루어졌다. 이항복의 시조 철령 높은 봉 을 대상으로 연구하였는데 이 시조가 문학치료의 감정을 논하기에 적합하기 때문이다. 이 시조에서 감정은 슬픔으로 독자에게 전이를 일으키고 있었으며 이는 문학치료의 효과를 말해주는 것이었다. 앞으로 이러한 연구가 계속되어 문학치료의 테크닉이 더욱 발전되길 기대한다.

BACKGROUND/OBJECTIVES: The anti-diabetic activity of pear through inhibition of ${\alpha}-glucosidase$ has been demonstrated. However, little has been reported about the effect of pear on insulin signaling pathway in obesity. The aims of this study are to establish pear pomace 50% ethanol extract (PPE)-induced improvement of insulin sensitivity and characterize its action mechanism in 3T3-L1 cells and high-fat diet (HFD)-fed C57BL/6 mice. MATERIALS/METHODS: Lipid accumulation, monocyte chemoattractant protein-1 (MCP-1) secretion and glucose uptake were measure in 3T3-L1 cells. Mice were fed HFD (60% kcal from fat) and orally ingested PPE once daily for 8 weeks and body weight, homeostasis model assessment of insulin resistance (HOMA-IR), and serum lipids were measured. The expression of proteins involved in insulin signaling pathway was evaluated by western blot assay in 3T3-L1 cells and adipose tissue of mice. RESULTS: In 3T3-L1 cells, without affecting cell viability and lipid accumulation, PPE inhibited MCP-1 secretion, improved glucose uptake, and increased protein expression of phosphorylated insulin receptor substrate 1 [p-IRS-1, ($Tyr^{632})$)], p-Akt, and glucose transporter type 4 (GLUT4). Additionally, in HFD-fed mice, PPE reduced body weight, HOMA-IR, and serum lipids including triglyceride and LDL-cholesterol. Furthermore, in adipose tissue, PPE up-regulated GLUT4 expression and expression ratio of p-IRS-1 ($Tyr^{632})/IRS$, whereas, down-regulated p-IRS-1 ($Ser^{307})/IRS$. CONCLUSIONS: Our results collectively show that PPE improves glucose uptake in 3T3-L1 cells and insulin sensitivity in mice fed a HFD through stimulation of the insulin signaling pathway. Furthermore, PPE-induced improvement of insulin sensitivity was not accompanied with lipid accumulation.

The physical properties of textile materials and thermal physiological responses of the human subjects were evaluated with 4 different types of the army combat uniforms including US, German, Korean and general uniforms for this study. 8 male adults were used as the human subjects and the tests were done in the environmental chamber that was $25{\pm}0.1^{\circ}C$ of temperature, $65{\pm}5%$ of relative humidity and below 0.3 m/sec of air velocity. The test protocol consisted the rest period for 20 min., the exercise period for 20 min., the rest period for 20 min., the exercise period under wind condition for 20 min., and the recovery period for 20 min. The human subjects walked with 4.5 km/hr for 10 min., ran 7.5 km/hr for 10 min. during the first exercise period and walked and ran with the same speeds under 3.5 m/sec of the air velocity that simulated outdoor condition during the second exercise period. The test results of the study were as follows; The wind condition affected the skin and microclimate temperature of the human subjects lower compared to without wind condition, but had insignificant effect on the humidity control. The low air permeability of Korean uniform caused blocking the elimination of the humidity from the body and the regulation of body temperature. However, Korean uniforms could be the excellent one with the designs considering the ventilation of the uniforms and the textile fabrics with better air permeability.

Objectives : This study was designed to investigate the effects of alcoholic fermentation extract from ovary and rind of pear on human skin. Methods : We investigated the effects of samples on human skin in terms of clinical trial. 32 of healthy volunteers, who lived in mokpo participated in clinical trial. Effects of sample on hygroscopicity and water-holding capacity were investigated. Sebum, moisture, scabrousness and desquamation were also investigated. Facial massages were conducted 8 times in each volunteers. Results : Single treatment group showed elevated levels of hygroscopicity (Normal : 106.4$\pm$2.1%, vs Pear : 114.1$\pm$6.2) and water-holding capacity (Normal : 87.1$\pm$4.4%, vs Pear : 96.2$\pm$1.3) on forearm of 16 volunteers respectively. In addition, massage group using sample showed elevated moisture (Control : 3.8$\pm$5.8%, vs Sample : 15.2$\pm$4.7%) and lowered scabrousness levels (Control : -12.3$\pm$4.4%, vs Sample : -22.0$\pm$5.2%) significantly. However, the levels of sebum did not affected by sample. Conclusions : These result suggest that alcoholic fermentation extract from ovary and rind of pear has moisturizing effect on human skin.

It can be said that the ultimate goal of advertising is creating consumers' buying intention and buying behavior toward advertised goods. But literature suggests that ads have both intended and unintended consequences, and one of the unintended consequences is that the idealized images of physical attractiveness found in advertising have negative impact on girls' and womens' self-perceptions. Thus, this study, using social comparison theory as a framework, was designed to investigate the influences of the images of models in ads portrayed in TV and fashion magazines on the purchasing intention, self-esteem and body satisfaction of college women. Using an experimental stimulus, a moving picture representing thin and attractive models in the context of advertising fashion goods, two conditions were manipulated and the subjects were placed into one of two groups randomly, the experiment group and the control group. The experiment group only was exposed to the ads portraying highly attractive models. Data were collected from two groups using same questionnaire. The data were analyzed using t-test, two-way ANOVA, and descriptive statistics. The findings were as follows: 1. The thin and attractive image of models in ads on buying intention had significant positive influence on buying intention(p<.05). 2. The thin and attractive image of models in ads had significant negative influences on self-esteem(p<.05). 3. The thin and attractive image of models in ads had significant negative influence on body satisfaction(p<.05). 4. The ideal body internalization had significant negative influences on body satisfaction(p<.05), but interaction effect of model's image and ideal body internalization on body satisfaction was not significant.

The present study was designed to see what the local cooling of different body regions especially head and neck, hands and feet effect physiological responses in cold environment. Four male subjects wore garments covering whole body except face and rested for 20 min and then they rested for 40 min with uncovered head, neck, hands and feet, respectively in a cold environment(10$\pm$1$^{\circ}C$, 50$\pm$5%R.H.) 1. Rectal temperature increased when hands and feet were exposed to cold environment respectively, and when head and neck, hands and feet were exposed to cold environment together. 2. Exposed skin temperatures fell in cold environment. And hands temperature was lower than any other exposed skin temperatures. The hands temperature was significantly lower when head was exposed than when head was covered. And the feet temperature were significantly lower when hands were exposed than when hands were covered. 3. Mean skin temperature was the lowest when head and neck, hands and feet were exposed simultaneously, In conclusion, skin temperatures of extremities were decreased due to exposure to the cold environment. Especially upper extremities were lower than lower extremities by exposed parts of the body. It seemed that the extremities played the role of cold receptors but head and neck didn't. And there were large heat losses from the unprotected head and neck. In cold environment of 1$0^{\circ}C$ , thus, it is suggested for the purpose of thermoregulatory responses that head and neck would be covered and extremities would be exposed, especially upper extremities.

This study uses digital imaging and communications in medicine (DICOM) files acquired after CT scan to obtain the absorbed dose distribution inside the body by using the patient's actual anatomical data; uses geometry and tracking (Geant)4 as a way to obtain the accurate absorbed dose distribution inside the body. This method is easier to establish the radioprotection plan through estimating the absorbed dose distribution inside the body compared to the evaluation of absorbed dose using thermo-luminescence dosimeter (TLD) with inferior reliability and accuracy because many variables act on result values with respect to the evaluation of the patient's absorbed dose distribution in diagnostic imaging and the evaluation of absorbed dose using phantom; can contribute to improving reliability accuracy and reproducibility; it makes significance in that it can implement the actual patient's absorbed dose distribution, not just mere estimation using mathematical phantom or humanoid phantom. When comparing the absorbed dose in polymethly methacrylate (PMMA) phantom measured in metal oxide semiconductor field effect transistor (MOSFET) dosimeter for verification of Geant4 and the result of Geant4 simulation, there was $0.46{\pm}4.69%$ ($15{\times}15cm^2$), and $-0.75{\pm}5.19%$ ($20{\times}20cm^2$) difference according to the depth. This study, through the simulation by means of Geant4, suggests a new way to calculate the actual dose of radiation exposure of patients through DICOM interface.
