Purpose : This study was designed to apply a "stage of change" exercise intervention program to obese children in elementary school and to examine its effects on their BMI, stage of change, process, and self-efficacy in exercise. Methods : The experimental group included 64 children in the fourth, fifth and sixth grades, from one elementary school, whose BMI was in the 85th percentile or more for their age groups. The control groups had 61 students from a different one elementary school whose conditions were the same as those of the experimental group. Results : After the stage of change exercise intervention was applied, the BMI of the experimental group decreased by a significant enough degree to conclude that the program was effective in decreasing BMI. After the application of the program, the experimental group experienced a significant increase in thier helping relationships, counter-conditioning, reinforcement and stimulus control compared to the control group. After the program, self-efficacy in terms of exercise increased significantly in the experimental group. Conclusion : A stages of change exercise intervention program has been shown to engage individual students and encourage them to maintain a higher fitness level that promotes self-efficacy in exercise and therefore moves them towards healthier lifestyles. Moreover, the study proved that a significant reduction of BMI was achieved by the stages of change exercise intervention program.

The Physicochemical, sensory and cooking properties of functionally fortified rice with dietary fiber and chitosan were compared with regular rice when the rices were cooked with pressure and electric cookers. Moisture content of functional rice before cooking was 11.11%, which was lower than 13.72% in regular rice. Accordingly, moisture contents of functional rice samples cooked both with pressure and electric cookers were lower than those of regular rice. L value showing the degree of lightness of cooked rice was significantly higher in rice samples cooked with pressure cookers. The a value, the degree of redness and the b value, the degree of yellowness, were the highest in the functional rice cooked with an electric rice cookers. Textural measurement of hardness using a rheometer showed the highest value in functional rice cooked with a pressure cooker. The degree of gelatinization measured using differential scanning calorimetry (DSC) before cooking showed higher onset gelatinization temperature (T_0) and peak gelatinization temperature (T_p) in functional rice compared with those in regular rice. The gelatinization enthalpy (ΔH) of functional rice was lower than that of regular rice, showing that functional rice had lower gelatinization energy compared with regular rice. When the samples were stored in a refrigerator for one week, the DSC showed faster retrogradation degrees in samples cooked with electric rice cooker, having significantly higher enthalpies of regular and functional rice cooked with electric cookers compared to those cooked with pressure cookers. The functional rice samples cooked with pressure cooker had higher consumer acceptance test values compared to those cooked with electric cookers.

To develop effective and safe acne vulgaris therapies with a continuing demand for new solutions, we investigated unique efficacy of an antibacterial agent from marine brown alga Eisenia bicyclis in treating acne vulgaris. The methanolic extract of E. bicyclis exhibited potential antibacterial activity against acne-related bacteria. The ethyl acetate fraction showed the strongest antibacterial activity against the bacteria among solvent fractions. Six compounds (1-6), previously isolated from the ethyl acetate fraction of E. bicyclis, were evaluated for antibacterial activity against acne-related bacteria. Among them, compound 2 (fucofuroeckol-A [FF]) exhibited the highest antibacterial activity against acne-related bacteria with a minimum inhibitory concentration (MIC) ranging from 32 to $128{\mu}g\;mL^{-1}$. Furthermore, FF clearly reversed the high-level erythromycin and lincomycin resistance of Propionibacterium acnes. The MIC values of erythromycin against P. acnes were dramatically reduced from 2,048 to $1.0{\mu}g\;mL^{-1}$ in combination with MIC of FF ($64{\mu}g\;mL^{-1}$). The fractional inhibitory concentration indices of erythromycin and lincomycin were measured from 0.500 to 0.751 in combination with 32 or $64{\mu}g\;mL^{-1}$ of FF against all tested P. acnes strains, suggesting that FF-erythromycin and FF-lincomycin combinations exert a weak synergistic effect against P. acnes. The results of this study suggest that the compounds derived from E. bicyclis can be a potential source of natural antibacterial agents and a pharmaceutical component against acnerelated bacteria.

Histiocytoid Sweet syndrome (HSS) is a rare inflammatory disease that has recently been described as a variant of Sweet syndrome. Histopathologically, HSS is characterized by papillary dermal edema with infiltration of histiocytoid cells into the upper dermis. The histiocytoid cells are easily misinterpreted as histiocyte, but in fact, they are immature myeloid cells. To demonstrate cells of myeloid lineage, specific staining must be performed, such as myeloperoxidase (MPO). To date, there are several HSS cases associated with hematological malignancy, drugs, and chronic inflammatory diseases. But, in Korea, only one case has been reported so far. Herein, we report a case of HSS developed in the patient with pure white cell aplasia and review the relevant literature. (Korean J Dermatol 2013;51(7):531∼535)

Epithelioid blue nevus is a rare variant of blue nevus that was first described in patients with Carney complex, a familial lentiginosis and multiorgan neoplasm (spotty cutaneous pigmentation, cutaneous/cardiac/mammary myxomas, endocrine overactivity, and psammomatous melanotic schwannomas). Epithelioid blue nevus is an intradermal melanocytic nevus composed of heavily pigmented globular and polygonal cells and lightly pigmented spindle and dendritic cells. Recently, cases of epithelioid blue nevi have been reported in patients without Carney complex. Herein, we describe a child who developed epithelioid blue nevus on her right foot without Carney complex symptoms and review the relevant literature. (Korean J Dermatol 2014;52(5):345∼348)

Circumscribed acral hypokeratosis (CAH) is a rare disorder characterized by a well-circumscribed and erythematous depressed patch on the palm or sole. It usually presents as an asymptomatic, solitary, long-standing lesion in middle-aged to elderly women. Histologically, it has a characteristic stair-like configuration between normal and involved skin with an abrupt thinning of the horny layer and a decreased granular layer. Although the pathogenesis of CAH is not well established, several hypotheses were proposed. To our knowledge, there have been only two cases to document HPV in a single lesion of CAH. Herein, we report the third case of circumscribed acral hypokeratosis with expression of human papillomavirus, high-risk type 16, 18.

Lichen amyloidosis is composed of firm, yellowish to brownish papules, usually found on the pretibial area. Amyloidosis of the auricular concha is a rare variant of primary cutaneous amyloidosis, presenting papules or plaques localized to the ear. Histopathologically, it is characterized by hyperkeratosis, acanthosis and deposition of eosinophilic materials in the papillary dermis similar to the presentation of lichen amyloidosis. Herein, We report a case of lichen amyloidosis occurring on the auricular concha of a 48-year-old Korean woman, presented with a 3-years history of asymptomatic monomorphous papules on her both ears.

This study was aimed to investigate factors that affected the status of wearing personal protective equipment (PPE) for handling poultry carcasses with potential exposure to virulent avian infectious agents. A large outbreak of high pathogenic avian influenza (HPAI) occurred in South Korea in 2014. Many public officers participated for euthanizing and handling livestock carcass. However, several safety issueswith using PPE were revealed. Therefore, a questionnaire survey was conducted for 340 people who participated euthanasia and carcass disposal in the place where HPAI mainly occurred in 2014. It was found that 31.8% of the respondents had ever taken off their protective equipment during operations because of its inconvenience. The most inconvenient PPE was goggles (54.6%), followed by mask (20.2%), latex gloves (11.6%), shoe covers (5.9%) and protective clothing (5.3%). The main complaints about this individual PPE was unclear sight, damp emitted toward eye, sweating, tearing easilyand sweating, respectively. Considering such problems of PPE, new possible directions for improvement of gloves and goggles were suggested. With newly developed rubber coating fabric gloves and conventionally using latex and fabric gloves, H3N2 influenza virus transmission experiment was conducted. Rubber coating fabric gloves showed similar efficiency for blocking virus transmission with latex laboratory gloves and were not easily torn by sharp claws of chicken. In addition, air flow control safety eyewear was suggested to minimize moisture formation. The air flow control system efficiently suppressed moisture formation inside the goggles. Therefore our study will provide more specific directions about new PPE development for safety protection of actual wearers.
