In this research, we applied FT-IR spectroscopy to study the hydrolysis of the ester-crosslinking formed by various polycarboxylic acids on the cotton fabric. We observed the following; (1) the ester-crosslinking is less durable to hydrolysis than ether-crosslinking under all conditions; (2) the ester-crosslinking formed by polycarboxylic acids having more than three carboxyl groups, such as butanetetracarboxylic acid (BTCA), are substantially more durable to hydrolysis than the acids having two or three carboxyl groups, such as maleic and citric acid; (3) alkaline conditions drastically accelerate the hydrolysis of both urea- and ester-crosslinking; and (4) the ester-crosslinking formed by poly(maleic acid) is more resistant to hydrolysis at alkaline conditions than BTCA. (5) polycarboxylic acid molecules were removed from the fabric at same rate as the hydrolysis of the ester linkage. FT-IR spectroscopy has proved to be a useful analytical technique for evaluating the hydrolysis of the crosslinked cotton fabric.

Objective : This study is to investigate the effect of Yukmijihwangtang Gamibang on Male Acne patients. Methods : We treated 3 male acne patients diagnosed as the deficiency of Yin with Yukmijihwangtang Gamibang and comedon extraction. After treatments We compared the before and after photos, and estimated by Korean Acne Grading System(KAGS). Results & Conclusions : After taking Yukmijihwangtang Gamibang, extruding comedones by needle and appling acupuncture, the acne was improved. This study shows that the acne can possibly be diagnosed as the deficiency of Yin. So further studies are needed continuously.

The effect of temperature, washing time, mechanical agitation and concentration on the removal from cotton fabrics of tripalmitin labelled with C\sup 14\ were studied. In order to correlate the detergency with the removal mechanism, solubilization and suspending power of surfactants were observed. RESULTS : 1. The detergency from cotton fabric was increased with elevating temperature and over the temperature of maximum detergency, the rate of soil removal was rather decreased. 2. The effects of washing time and mechanical agitation on the removal of triplamitin were obvious at lower temperature. 3. The removal of tripalmitin was remarkably increased at higher concentration over cmc for all surfactants. The detergency of nonionic surfactant -NPPG- was best, this was resulted from its large solubilization and suspending power.

본 연구는 배 과즙의 가공조건을 최적화하기 위해 여과, 청징 및 갈변 방지 방법 및 가공 조건에 따른 항산화능을 조사하였다. 배를 분쇄 착즙 후 면포여과, 감압여과 및 원심분리를 실시한 결과 원심분리(3000 rpm, 10분간)를 할 경우 colorimetry value가 높은 'L'값(34.31)과, 낮은 'a'값(-0.13)을 보여 가장 좋은 청징 효과를 나타냈으며, 그 다음으로 감압여과(31.8%) 및 면포여과(11.0%) 순이었다. 청징제 종류에 따른 청징 효과는 1%의 gelatin이나 bentonite가 우수하였으며, tannin과 egg albumin은 효과가 없었다. 갈변저해제 처리에 따른 갈색도 측정결과 0.1% L-ascorbic acid 처리 시 11.5%의 갈변억제 효과를 보였다. 유리당은 fructose, sucrose, glucose, sorbitol이 검출되었으며, 가열배즙에서 fructose와 glucose는 증가되는 반면 sucrose는 감소되었다. 가공 조건에 따른 항산화능 조사 결과 총폴리페놀 함량은 가열배즙이 청징배즙에 비해 유의하게 많아졌으나 총플라보노이드 함량은 청징배즙과 가열배즙이 유사하게 증가하였다. DPPH radical 소거활성과 아질산염 소거능은 가열배즙과 청징배즙에서 착즙액보다 유의적으로 높은 것을 확인할 수 있었다.

Purpose: Nevus comedonicus is a rare disease involving abnormal development of the pilosebaceous unit, clinically appearing confluent clusters of open comedones. It is characterized by follicular epidermic invaginations filled with keratin, with atrophic pilose or sebaceous structures which are open to the lower pole of the invagination. We report a child with inflammatory pustules and cysts correlated to the nevus comedonicus. Methods: A 15-month-old girl was referred for treatment of a nevus comedonicus that has been developed since birth. There were periodic episodes of erythema and swelling of the plaque. The patient had treated previously with retinoid cream for 2 weeks without obvious benefit at dermatology clinic. We excised the nevus comedonicus with Y-shape leaving some lesions. Results: When we incised skin, we could see multiple large whitish cysts beneath the nevus comedonicus. Histopathologic findings showed deep invagination of epidermis filled with keratin plugs, keratinous cyst in the dermis, rudimentary hair follicle. Conclusion: We treated rare nevus comedonicus with multiple large cysts as surgical excision.

Polycarboxylics acids are used as crosslinking agents for cotton cellulose to produce durable finished press cotton fabric. It has been observed that the strength of the cotton fabric treated with polycarboxylic acids showed significant reduction as a result of the crosslinking process. The effect of acid-catalyzed depolymerization on the tear strength of cotton fabric is investigated by evaluating the cotton fabric treated by succinic acid, which does not crosslink cotton cellulose and form little ester on the cotton fabric. We find that the tear strength of cotton fabric treated with succinic acid decreases at elevated temperature due to acid-catalyzed depolymerization of cellulose. The magnitude of fabric strength reduction increases as the acid concentration increases. At a constant acid concentration, it increases as the curing temperature and time increases. It decreases as the pH of the acid solution increases. We also find that the dissociation constant of an acid also has a significant effect on the fabric strength reduction. The magnitude of fabric tear strength reduction increases as the acid dissociation constant decreases.

In this research, we investigated hydrolysis of the ester crosslinking on cotton fabric treated with polymer of maleic acid(PMA), citric acid(CA) and combination of polymer of maleic acid and citric acid using Fourier transform infrared spectroscophy. The rate of hydrolysis of the ester crosslinkage increased with pH regardless of the type of polycarboxylic acid used and even after hydrolysis for 256 hour in pH 13_4 solution, the treated fabric retained $10-20\%$ ester crosslinkage. The durability to alkaline hydrolysis of the ester crosslinkage formed by CA was lower than that of by PMA and combination of poly(maleic acid) and citric acid indicating that the ester formed by CA on the cotton fabric is more susceptible to hydrolysis than that formed by PMA and combination of PMA and CA. The total amount of ester and polycarboxylic acid molecules removed from fabric increased with increasing hydrolysis time but the rate of hydrolysis of ester linkage were higher than that of removal of polycarboxylic acid molecule from the fabric. The characteristic of hydrolysis of fabric treated with combination of PMA and CA was related with the mixing ratio of PMA and CA in treating fabric.

Objectives : The purpose of this study is to investigate the differences of skin disease, particularly Acne between the rotating shift work nurses and the nurses on a fixed day schedule. Methods : Questionnaries were distributed to 30 rotating shift work nurses(the rotating group) and 34 nurses on a fixed day schedule(the daytime group). The questionnaris included questions on general health concepts, insomnia skin disease(particularly Acne), gastroenteric trouble, menstrual irregularity. Result : 1. There was significant difference on skin disease(particularly Acne) between two groups. 2. There was no significant relation between Gastroenteric trouble and Acne. But, in particular, there was significant relation between Constipation, Gastritis and Acne. 3. There was no significant relation between menstrual irregularity and Acne. 4. In Acne group, more than 70% felt the necessity of treatment, but only 2.5% used Korean Oriental Medical therapy. Conclusion : Disorder of circadian rhythm affects the skin disease(particularly Acne) more than Gastroenteric trouble and menstrual irregularity. But in this study, the total number of the nurse is not enough. So we need more accurate study about the aspects of skin disease. And about the Acne, publicity of Korean Oriental Medical therapy is required.

An analysis of the components of clay mineral before and after coloration (XRF) showed that the elements involved in coloration are Fe, Cr, and Ni. Fe accounts for 65% of coloring components on dyed fabric; in addition, Cr and Ni also affect coloring. The optimal coloration condition was to repeat the process of immersing the cotton fabric in $80^{\circ}C$ slurry of 8g of clay mineral to 1g cotton for 60 minutes, dry it for 24 hours and rinse three times. Especially, as the repetition of coloration increased, the $(K/S)_{440}$ value of sample A increased from 1.0 to 2.5, and sample B increased from 1.0 to 1.6. The effect of the repeated process on coloration was significant; consequently, the rinsing and drying process were important to decrease the coloration level. It also showed excellent results in regard to color fastness to washing, light, rubbing, perspiration, and antibiotic effect.
