The purpose of the study is to clarify the relationship between hair style and personal character. This is elucidated by using the standard model of their preferred hair style to their individual to their personality. The study is primarily centered around college woman, who reside in Young dong area. The research suggested that In the age group 19-25 subjects preferred their hair to be shoulder length or longer. This is in contrast to the older age group preferring a shorter hair style. Certainly most subjects under the age of 25 preferred their natural hair texture as opposed to permed hair fashioned by older subject. Difference is personality traits was not a factor here. There is a relationship between personality traits, personal background and whether or not subjects dyed or decolored their hair. Subjects responded "yes" which means that they are easily affected by the two factors. The response to the other question of which color they chose, if they dyed and decolored, was that the most of the cases preferred brown color because brown is a natural looking hair color. Their responses from the question "what kind of style they want, if they can change their style differently", they preferred a fashionable hair style. In most cases, individual responded that they change their hair style once in every two or three months. Of all the personality traits, 48.1% were adventurous, changingtheir hair style more than once in every 6 months. The main reason they change their hair style is that they are bored with their old style. In the under 25 age group, the cost of changing their hair style is usually paid for by the subjects parents, however a few responded that they paid for themselves. Over the age of 25 years 80% usually paid for themselves. Additionally students who supported themselves financially paid for hair restyling themselves. When changing a hair style most subjects consider that new hair style should go with their existing image. "What kind of image they want to show others？" almost all of them responded that they want to look sophisticated and fashionable, In the age group 25 and over who belong to the upper class want their hair to look healthy and a full of body. They also responded about their changing their hair style to show a different appearance positively,fferent appearance positively.

This study was carried out to investigate preference and purchase factors of seaweed in some regional residents of Korea. Subjects were residents (n = 1,218) whose residential area was divided into inland and coastal region and the survey was done during December 2007. Especially, purchase factors of seaweeds was conducted only in married females (n = 353). The subjects are composed of 46.5% male and 53.5% female. Regional distribution of subjects was found to be 16~17%, with highest ratio in the age bracket of 20~29 years old. Proportion of students, at 29.8%, was the highest ranking occupation of the subjects. Preference score of seaweeds by region was highest for laver followed by brown seaweed and sea tangle. In terms of preference by gender, female subjects displayed higher preference score for green laver (p < 0.01), seaweed fusiforme, brown seaweed, sea tangle (p < 0.001) than the male subjects. Considerations being made when purchasing seaweeds for each region were in the order of freshness, taste and nutrition. In comparing the inland and coastal region, scores of freshness, convenience, design and color for the coastal region was higher, displaying significant difference.

Purpose: In an amputated auricle, a microvascular anastomosis is the best treatment of choice. But, the neartotally amputated auricle which is connected by very narrow tissue pedicle to the head, can survive by simple attachment without a microvascular anastomosis owing to the rich vascular network through the superficial temporal artery and posterior auricular artery. In cases of venous congestion resulting from a lack of vein anastomosis, medical leeches (Hirudo medicinalis) can solve the problem. We are reporting the case of a 6-year-old boy who had a neartotally amputated auricle with successful results by simple closure and medical leech treatment without a microvascular anastomosis. Methods: A 6-year-old male patient had an left auricular injury by an escalator accident. The left auricle was neartotally amputated from the temporal head with connection only by very narrow skin and subcutaneous pedicle (about 1 cm in width) at the helical root of upper and anterior part of auricle. Marginal bleeding from the avulsed auricle was noted and the arterial blood was supplied from a branch of upper auricular branch of the superficial temporal artery. The auricle was repaired by simple closure including cartilage and skin without any vascular anastomosis. After simple closure, the auricle showed good circulation with pink color. But on the 2nd day after the operation, there was a venous congestion with severe swelling, which resulted in a purplish colored auricle. The venous congestion disappeared after using medical leeches by the 5th day after the operation. Results: The repaired auricle showed aesthetically and functionally satisfactory result with normal development at the 9 months follow-up check after the operation. Conclusion: In cases of neartotally amputated auricles of children or crushing injury in which microsurgery is difficult, we can try simple closure with the use of medical leeches in treating a of venous congestion for a successful result.

A 10 years old female Poodle weighing 4.38 kg and a 10 years old female Maltese weighing 4.33kg were referred to veterinary leaching hospital of college of veterinary medicine, Konkuk uni-versity because of hematuria and severa anorexia. Preoperative hematological and srum chemical values revealed that counts of WBC were $78.4{\times}10^3$,/TEX>/ul in the Poodle and $21.6{\times}10^3$in the Maltese, concentrations of BUN 105 and 13 mg/dl, concentrations of creatinine 4.0 and 1.4 mg/dl, concentration of ALKP 542 U/L in the Poodle and concentration of ALF 37 U/L in the Maltese, respectively. Radiographic findings were observed radiopaque bilateral nephroliths in the Poodle and right renal cal- culus in the Maltese. Ultrasonographic findings were showed hyperechoic mass with severe acoustic shadowing, which were ]ocated in the center of both kidneys parenchyma in the Poodle and in right kidney in the Maltese. Bisectional nephrotomy in right kidney for removal of calculus, which had ,sin- gle stone and more large than splitted stones in lets kidney in the Poodle, was performed under isnf- lurane anesthesia in 100% $O_2$. The time from temporary occlusion of blood flow to suture of incisioned kidney after removal of renal calculi was elapsed 12 minutes. During operation and until 24hrs after operation was infusioned mannitol and tranexanic acid solution. There were normal urination with yellow color in the Poodle at 3 days after operation and in the Maltese at 1 day and good appetite after 7 days and 1 day after operation. At 7 days and 9 days after operation, hematolgoical and seam chemical values repealed that counts of WBC were $29.8{\times}10^3/u1 in the Poodle and 13.1 {\itmes}10^3$/ul in the Mal- tese, concentrations of BUN 13 and 10 mg/dl. concentrations of creatinine 1.3 and 1.1 mg/dl, con-centrations of ALT 34 and 97U/L, concentraion of AST 10 U/L in the Poodle, respectively, By ultra-sonographic view there was not observed hyperechoic mass and radippaque calculus in operated kid-ney in radiographic view.

Background: Indiscriminate use of antibiotics in livestock and poultry farming has caused emergence of new pathogenic strains. The situation has warrented the development of safe and alternative growth promoters and immunity enhancers in livestock. Herbal additives in animal and bird feed is a centuries-old practice. Thus, the present study investigated the efficacy of a standardized formulation of lipophilic turmeric extract containing curcumin and turmerones, (TF-36), as a natural growth promoter poultry feed additive. Methods: The study was designed on 180 one-day old chicks, assigned into three groups. Control group ($T_0$) kept on basal diet and supplemented groups $T_{0.5}$ and $T_1$ fed with 0.5% and 1% TF-36 fortified basal diet for 42 days. Each dietary group consisted of six replicates of ten birds. Body weight, food intake, food conversion ratio, skin colour, blood biochemical analysis and antioxidant status of serum were investigated. Results: Body weight improved significantly in $T_1$ with a 10% decrease in FCR as compared to the control. TF-36 supplementation in $T_1$ enhanced the antioxidant enzyme activity significantly (p < 0.05) with a decrease (p < 0.05) in lipid peroxidation. It also caused a slight yellow skin pigmentation without any change in meat color, indicating the bioavailability of curcumin from TF-36. However, no significant change in the concentration of serum creatinine, total protein and liver enzyme activities were observed, indicating the safety. Conclusion: In summary, we concluded that TF-36 can be a natural feed additive to improve growth performance in poultry, probably due to the better antioxidant activity and antimicrobial effects contributed by the better bioavailability of curcuminoids and turmerones. Besides, curcuminoids and turmerones were also known to be gastroprotective and anti-inflammatory agents.

Supernova (SN) cosmology is based on the assumption that the width-luminosity relation (WLR) in the type Ia SN luminosity standardization would not vary with progenitor age. Unlike this expectation, recent age datings of stellar populations in host galaxies have shown significant correlations between progenitor age and Hubble residual (HR). It was not clear, however, how this correlation arises from the SN luminosity standardization process, and how this would impact the cosmological result. Here we show that this correlation originates from a strong progenitor age dependence of the WLR and color-luminosity relation (CLR), in the sense that SNe from younger progenitors are fainter each at given light-curve parameters x1 and c. This is reminiscent of Baade's discovery of two Cepheid period-luminosity relations, and, as such, causes a serious systematic bias with redshift in SN cosmology. We illustrate that the differences between the high-z and low-z SNe in the WLR and CLR, and in HR after the standardization, are fully comparable to those between the correspondingly young and old SNe at intermediate redshift, indicating that the observed dimming of SNe with redshift is most likely an artifact of over-correction in the luminosity standardization. When this systematic bias with redshift is properly taken into account, there is no evidence left for an accelerating universe, and the SN data now support a decelerating cosmic expansion. Since the SN cosmology has long been considered as the most direct evidence for an accelerating universe with dark energy, this finding poses a serious question to one of the cornerstones of the concordance model.

An experiment was conducted to evaluate the effects of bacteriophage supplementation on egg performance, egg quality, excreta microflora, and moisture content in laying hens. A total of 288 Hy-line brown commercial laying hens (36-wk-old) were randomly allotted to 4 treatments in this 6-wk trial and dietary treatments included: i) CON, basal diet; ii) T1, CON+0.020% bacteriophage; iii) T2, CON+0.035% bacteriophage; iv) T3, CON+0.050% bacteriophage. There were 6 replicates for each treatment with 6 adjacent cages (2 hens/cage). Laying hens in T2 and T3 treatments had higher (p<0.05) egg production than those in CON and T1 treatments during wk 0 to 3. In addition, egg production in T1, T2, and T3 treatments was increased (p<0.05) compared with that in CON treatment during wk 4 to 6. At wk 4 and 5, birds in T2 group had higher (p<0.05) HU than those in CON. In addition, at wk 5 and 6, HU in birds fed T1 and T3 diets was greater (p<0.05) than those fed CON diet. E. coli and Salmonella spp. concentrations in excreta were decreased (p<0.05) by T1, T2, and T3 treatments. However, egg weight, egg shell color, yolk height, yolk color unit, egg shell strength, egg shell thickness, egg gravity, and excreta moisture content were not influenced by dietary treatments during the entire experimental period. In conclusion, bacteriophage supplementation has beneficial effects on egg production, egg albumen, and excreta microflora concentration in laying hens.

Cutaneous squamous cell carcinoma (SCC) is the second most common skin malignancy. This report describes the case of an unusual extensive SCC involving the whole hemiface, which required reconstruction with a combination of a dual vascular free transverse rectus abdominis muscle (TRAM) flap and a skin graft. A 79-year-old woman visited our hospital with multiple large ulcerated erythematous patches on her right hemiface, including the parieto-temporal scalp, bulbar and palpebral conjunctiva, cheek, and lip. A preliminary multifocal biopsy was performed in order to determine the resection margin, and the lesion was resected en bloc. Orbital exenteration was also performed. A free TRAM flap was harvested with preserved bilateral pedicles and was anastomosed with a single superior thyroidal vessel. The entire TRAM flap survived. The final pathological examination of the resected specimen confirmed that there was no regional nodal metastasis, perineural invasion, or lymphovascular involvement. The patient was observed for 6 months, and there was no evidence of local recurrence. Usage of a TRAM flap is appropriate for hemifacial reconstruction because the skin of the abdomen matches the color and pliability of the face. Furthermore, we found that the independent attachment of two extra-flap anastomoses to a single recipient vessel can safely result in survival of the flap.
