This study intends to expose the recognition on stage makeup and its effects on the psychological state and stage performance through a filed investigation on 52 college students majoring drama and cinema, who participated in ‘Young Theater Festival’. While the festival was held in Seoul from June 19 to July 6 2014, these young students were selected because their sheer stage experience would make them more sensitive to external stimulus than experienced actors. The results of this study are summarized as follows, First, the psychological state invoked by the stage makeup turned out more positive and secured when the actor felt satisfactory with the makeup. The stage performance was also met with positive response beyond the overall average when the actor felt satisfied with the stage makeup. Second, the correlation analysis undertaken for the four factors aforesaid revealed that there are positive co-relations between makeup recognition and psychological state, makeup recognition and degree of satisfaction, and degree of satisfaction and psychological state. The stage makeups were confirmed to have crucially exerted positive impacts on the actors’ psychological state and stage performance (degree of satisfaction).

Radio frequency and iontophoresis are two commonly used types of medical skin care equipment, utilizing electrical energy. Radio frequency technology has become an important treatment in aesthetic medicine, and has many applications, including non-ablative tightening of the cutaneous tissue to improve skin laxity and to reduce wrinkles. Iontophoresis on the other hand uses a small electric charge to deliver medicine or other chemicals through the stratum corneum, the principle barrier to percutaneous absorption, without the use of a needle. It is used mainly for aesthetic reasons, including treatment of melasma, and for anti-aging therapy. Effective cosmetic results have been demonstrated for both these techniques in a number of studies. However, recklessness and incorrect use of the machines by unqualified practitioners can cause side effects. Here, we review the possible side effects and related coping strategies associated with radio frequency and iontophoresis.

The purpose of this study was to investigate the nutrition information sources and the nutrition knowledge in 41 rhythmic gymnasts aged 14.8±1.5 years and 17 coaches by questionnaires. Information about weight control, nutritional knowledge and its source, and food intake were collected by individual interview. Food intake was investigated with the 24 hours recall and two days dietary record methods. The results were as follows. All rhythmic gymnasts had experienced weight control. Most of them (97.6%) preferred `food restrict` as methods for weight control. Only fifty-one percent of rhythmic gymnasts had ever received the nutritional information. Their major information sources were parents & friends (76.2%). Eighty-two percent of rhythmic gymnasts wanted to obtain the nutritional information from the mass media and nutritionist & dietitian by the methods such like internet or nutrition counseling. Seventy-seven percent of coaches had ever counseled rhythmic gymnasts on nutrition, especially on the diet for weight control (92.3%). Their major information source were the mass media and curriculum. All coaches wanted to get the nutritional information from the nutritionist & dietitian and specialized books & dictionary by the methods such like internet or nutrition counseling. Total nutritional knowledge score of rhythmic gymnasts was 28.4 of 50 scores. Categorical score was the highest at the knowledge on `food source` and the lowest at the knowledge on `food exchange`. Total nutrition knowledge score of coaches was 37.6 of 50 scores, and higher than score of rhythmic gymnasts. Categorical score was the highest at the knowledge on `food sources` and the lowest on `food exchange` like rhythmic gymnasts. All nutrient intakes except vitamin C were higher in the group have received nutrition information compared with the group have not. In conclusion, it is very necessary to give rhythmic gymnasts and their coaches professional nutrition information by the information sources and methods they want. It could be helpful for improving the nutrition knowledge and enhancing performance of rhythmic gymnasts.

Syphilid represents a great variety of clinical and histological patterns. As such, sometimes it is difficult to make a differential diagnosis from other skin diseases. The histopathologic findings of syphilid are different, according to the clinical types; macular, maculopapular, papulosquamous, and nodular type. Characteristically, there is a marked perivascular infiltration of plasma cells and lymphocytes with endothelial cell swelling in the dermis. Herein, we report a case of syphilid showing the unusual histological pattern of granulomatous inflammation. A 45-year-old male presented with erythematous papules on the scalp, trunk, arms and inguinal area for 2 months. The biopsy specimen showed a chronic granulomatous inflammation with multinucleated giant cells in the dermis. Serologic test for syphilis showed a strong positive, and the patient was diagnosed with secondary syphilis. He was treated with benzathine penicillin G and the skin lesions have successfully disappeared.

현미의 기능성을 증명하기 위하여 열수, 에탄올 추출하여 여러 가지 생리활성에 대하여 조사하였다. 우선, 아질산염 소거능 분석에서는 현미 열수와 에탄올 추출물 1 ㎎/㎖ 농도, pH 1.2에서 75.4와 94.9%을 나타내었고, xanthine oxidase 저해능은 현미 에탄올 추출물 10 ㎎/㎖에서 72.9%로 같은 농도의 열수 추출물보다 높게 측정되었다. 현미의 소화율(44.46±6.09%)은 백미의 소화율(62.71±4.18%)보다 낮으며 α-glucosidase 저해능은 현미 에탄올 추출물 10 ㎎/㎖에서 93.1%로 같은 농도의 열수 추출물보다 높게 측정되었다. 현미 열수와 에탄올 추출물의 SOD 유사활성은 10 ㎎/㎖에서 56.4와 44.9%로 유의적인 큰 차이는 없었다. 현미의 숙취해소 효능은 ADH와 ALDH 활성증진에 현미 열수와 에탄올 추출물이 미치는 영향을 조사함으로써 증명하고자 하였는데 그 결과, 현미 에탄올 추출물에서 알콜 분해능 증가율이 나타났다. Physiological activities of hot water (BRW) and 80% ethanol (BRE) extracts from brown rice were investigated in this study. The highest activity (94.9%) of nitrite reductase was observed for BRE at 1 ㎎/㎖ at pH 1.2, while the activity for BRW was about 75.4% under the same conditions. The inhibitory effects of BRW and BRE on xanthine oxidase activity were about 39.0 and 72.9% at 10 ㎎/㎖, respectively. The digestibility of starch was lower for brown rice than for milled rice and the highest inhibition (93.1%) of α-glucosidase activity occurred with BRE. Superoxide dismutase (SOD)-like activities of BRW and BRE were weakly increased in a dose-dependent manner and were about 56.4 and 44.9% at 10 ㎎/㎖, respectively. The influences of BRW and BRE on alcohol metabolizing activity were determined by measuring the generation of reduced nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH). Increases in ADH and ALDH activities were only detected with BRE.
