In this study, we developed a scalp protect powder (scalp irritation abirritant). We proved this powder can lessen sensitivity of skin against diamine dyes (PPD, PTD, etc.) by carrying out safety test and clinical experiments. This scalp protect powder accelerates dyeing process, and reduces not only scalp irritation but also hair damage. Using our optimum formula, ammonia can be caught in liquid-crystalline structure, subsequently, bad odor is reduced dramatically.

This study was conducted to survey the perception of domestic consumers about traditional pork dishes, and to utilize the survey result as a basis for the development of processed pork products. A survey was conducted on 218 domestic consumers regarding the following: general questions, propensity and preference to consume pork dishes, pork dishes feasible for export, and the types and problems of processed products feasible for export. The results of the survey showed that the respondents consumed pork dishes 3-4 times a month on average and they appeared to consume the pork dishes most frequently in specialized restaurants. The highest preference was shown in Samgyeopasal gui (grilled pork belly) and Galbi gui (grilled pork rib) among the pork dishes, whereas the lowest preference was shown in Kkubdegi gui (grilled pork skin) and Gookbob (boiled rice and pork served in soup). When the type of processed pork products available according to pork dishes were analyzed, the result showed that Samgyeopasal gui (grilled pork belly) and Nirbiani (slices of roast, seasoned pork in width) could be developed as a frozen product, Geyook Bokeum (stir-fried spicy pork), Bulgogi (Korean-style barbecued pork), and Galbi jjim (braised short ribs) could be developed as a retort product, and that Bossam (boiled pork eaten with a salty sauce and wrapped in greens), Pyeonyuk (slices of boiled pork), Jokbal (pork trotters), and Sundae (kneading together seasoned mixture of vegetables and glass noodles stuffing it into casings made of hog intestines, which are then tied off at the ends and boiled) could be developed as a vacuum-packed product. When the survey concerning the problems expected in the development of processed products using pork dishes was conducted, the result showed that there could be a texture change issue for Galbi gui, Samgyeopasal gui and Nirbiani; a preservation issue for Bossam, Pyeonyuk; a safety issue for Bulgogi and Geyook Bokeum; a taste and flavor change issue for Geyook Bokeum and Sundae; and a packaging issue for Gookbob.

A new and unique class of nonionic surfactants was synthesized by reacting biological a-tocopherol with ethylene oxide for functional cosmetics. The structures were confirmed by Hl-UMR, FT-lR, TLC and elemental analysis. POV and conjugated diene value study for EPO showed POE(n)TE had antioxidative effect similar to tocopheryl acetate Protective effect on cell membrane in photohemolysis of POE(5)TE, POE(10)TE and POE(18)TE were slightly lower than tocopherol but higher than nonoxynol-12, and POE(10)TE had UV absorption power comparable with tocopherol and homosalate. Biological activity of the hydrophobic group of the new surfactants make them unique and different from those of conventional nonionic surfactants Systematic safety evaluations of POE(n)TEs on the skin and eye proved that they are as safe as tocopherol. The results of physicochemical study showed POE(10)TE had the lowest CMC value, POE(18)TE had the maximum surface tension reduction and the highest foam volume and POE(n)TEs had various HLB values by the degree of ethoxylation. The test resul Is of technological and practical applications of these surfactants for cosmetics showed some POE(n)TEs were superior to conventional surfactants. POE(5)TE in W/O emulsions, POE(10)TE and POE(12)TE in O/W emulsions, POE(12)TE in dispersions, POE(18)TE in solubilizations and POE(50)TE in gelations were shown to be excellent which was considered due to the structural characteristic and formation of liquid crystals of POE(n)TEs. By the development and applications of these excel lent multi-functional surfactants, innovative functional cosmetics were successfully formulated.

Even though maxillary cancer is usually discovered in advanced stage, its regional lymph node or distant metastases are not common comparing to other head and neck cancer. So the result of treatment depends upon local control of the tumor. Because maxillary sinus is anatomically located adjacent to orbit and skull base, it is difficult to remove the tumor completely with sufficient safety margin like in other malignant tumor. Traditionally, surgery including aggressive resection, radiotherapy or both combined therapy have been widely accepted in many institutes, but their results are not still satisfactory. Sixteen cases of maxillary cancer( all squamous cancer, T2 1 case, T3 6 cases, T4 9 cases, mean age 57.2 years) were treated by intraarterial chemotherapy, raditherapy and surgery and followed up retrospectively. 5 year survival rate by Kaplan-Meier method was 51.95%, and orbit, palate or cheek skin could be preserved in many cases and their functional result was good.

Stroke patient needs rehabilitation after receiving an acute treatment in a hospital. When stroke patient gets involved in an early discharge program, home care nurse plays a pivotal role to make them to gain a full strength and to come back to his/her prior life before he/she is sick. In spite of the importance of home care nursing intervention protocol for home care nurses to perform home care nursing autonomously, home care nursing intervention protocol for stroke patient is rarely developed. Therefore this study was conducted to develop home care nursing protocol that is applicable for stroke patients in home care nursing area. 41 home care nursing charts for stroke patients registered in home care nursing agencies from December 1st 1994 to August 31st 1999 at Y hospitals in Seoul and Won-Ju city were analyzed. 44 home care nurses who were having over three years' experience on stroke patients were participated in this study as a user validity validation group. The results of this study are as follows. 1. 28 nursing diagnoses were selected on the basis of evaluation of nursing diagnoses of stroke patients presented in a previous literature and case studies on home care nursing. 2. 17 nursing diagnoses were classified through the frequency analysis of home care nursing charts for 41 stroke patients who had received home care nursing. The order of sequence was like these: impaired skin integrity, risk for infection, nutritional deficit, impaired physical mobility, constipation, knowledge deficit, ineffective airway clearance, anxiety in family members, risk for aspiration, self care deficit, altered urinary elimination, ineffective individual coping, social isolation, risk for injury, self-esteem disturbance, impaired verbal communication, fatigue of family caregiver. 3. Based on validation on expert and user validities, 44 nursing interventions which were above ICV=.80 were chosen. 4. Nursing intervention protocols which showed above ICV=.90 were developed and were like these; pressure ulcer care, position change, preventive care for circulatory dysfunction, tube care : catheter, vital sign monitor, constipation/impaction management, artificial airway management, suction of airway secretion, environmental management : safety, and fall prevention.

Because the previous design procedure for the composite wind turbine blade structure using trial and error method takes long time, a improved design procedure by using the program based on classical laminate theory was proposed to reduce the inefficient element. According to the improved design procedure, limitation of strains, stresses and displacements specified by international standard specification IEC1400-1 for the composite wind turbine blade were applied to sizing the structural configuration by using the rule of mixture and the principal stress design technique with a simplified turbine blade. Structural safety for strength and buckling stability was confirmed by the developed analysis program based on the laminate theory to minimize the design procedure. After modifying the preliminary design result with additional structural components such as skin, foam sandwich and mounting joints, stresses, strains, displacements, natural frequency, buckling load and fatigue life were analyzed by the finite element method. Finally these results were confirmed by comparing with IEC1400-1 specification.

Mercury is a toxic and non-essential metal in the human body. Mercury is ubiquitously distributed in the environment, present in natural products, and exists extensively in items encountered in daily life. There are three forms of mercury, i.e., elemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. This review examines the toxicity of elemental mercury and inorganic mercury compounds. Inorganic mercury compounds are water soluble with a bioavailability of 7% to 15% after ingestion; they are also irritants and cause gastrointestinal symptoms. Upon entering the body, inorganic mercury compounds are accumulated mainly in the kidneys and produce kidney damage. In contrast, human exposure to elemental mercury is mainly by inhalation, followed by rapid absorption and distribution in all major organs. Elemental mercury from ingestion is poorly absorbed with a bioavailability of less than 0.01%. The primary target organs of elemental mercury are the brain and kidney. Elemental mercury is lipid soluble and can cross the blood-brain barrier, while inorganic mercury compounds are not lipid soluble, rendering them unable to cross the blood-brain barrier. Elemental mercury may also enter the brain from the nasal cavity through the olfactory pathway. The blood mercury is a useful biomarker after short-term and high-level exposure, whereas the urine mercury is the ideal biomarker for long-term exposure to both elemental and inorganic mercury, and also as a good indicator of body burden. This review discusses the common sources of mercury exposure, skin lightening products containing mercury and mercury release from dental amalgam filling, two issues that happen in daily life, bear significant public health importance, and yet undergo extensive debate on their safety.
