Demand for cosmetics with functionality and eco-friendliness has increased dramatically due to recent aging, well-being trends, and increased interest in beauty. Cosmetics production in 2014 was 8,970.4 billion won, an increase of about 50% compared to 6,014.6 billion won in 2010. In the midst of this, similar companies in intense competition are pursuing differentiated strategies and innovation activities to solve quality, price and delivery problems. In particular, cosmetics packaging work is getting more difficult due to the increasing bill of materials (BOM) and difficult assembly methods. Therefore, in this study, the following problems were identified and suggestions for the improvement of the packaging Many research laboratories such as biotechnology, chemistry, and pharmaceuticals, which are undergoing various studies, are equipped with ready-made laboratory safety equipments such as bio-safety workbenches, aseptic bases, and exhaust workbenches. However, most researchers are disadvantaged in using existing safety equipment. This is because existing safety equipment can not take into account all of the unique characteristics of the research. For this reason, researchers are demanding the development of customized safety equipment that is well suited to their research needs. process of Company C, which is facing difficult situation to respond to the customer 's delivery due to the 52 - hour work week. First, we used the stopwatch to find the difficulty process in the packaging process and show ways to improve it. Second, to improve the efficiency of line balancing in the packaging process, we integrate processes, improve work methods, and perform simple automation. As a result, the prepare loss for replacement was reduced by 1 minute from 5 minutes, resulting in a 23% increase in productivity from 112 ea./hour to 137ea./ hour per person. At this time, the LOB of the packaging process was improved from 70% to 82% by operating one more production line through one person per line, total 9 people saving.

Korean Ginseng is a medicinal herb which grows naturally in korea. an ancient country situated in north-eastern Asia. Its medical use was already well known to herb doctors in this region about five thousand years ago since the effectiveness of korean ginseng has been recognized through practical use for a long time. Korean Ginseng has always been regarded as a devine cure. The name "Ginseng" can be found in various medicinal books. many of which were written as early as B.C. 100. In the records of many chinese medical books. dating from the inception of publishing, it was noted that Korean Ginseng was of the highest level of quality. Korean Ginseng originally grew in the mountains of korea. However, this wild Korean Ginseng(js called SANSAM) could not meet the ever-increasing demands. and from the 16th century. it has been cultivated on farms for mass processing and supplying in korea(js called INSAM). It was already recognized in korea a long time ago(B.C. 57 - A.D. 668) that Korean Ginseng possessed the qualities of panacea, tonic and rejuvenator, and had other medicinal properties as well. The effectiveness of Korean Ginseng is widely recognized among south-eastern Asians as well as Chinese. As its effect has been proved scientifically. Korean Ginseng is now becoming the ginseng for all human beings in the world. Korean ginseng is differently called according to processing method. Dried thing is Insam(white ginseng), boiled or steamed is Hongsam(red ginseng). 장뇌삼(long headed ginseng) is artificially grown in the mountain no in field for a long time. So the body is thin and some long. but ingredients are concentrated. Korean wild ginseng(SANSAM) is rare in these days but we developed cosmetic ingredient. The scientific name of Korean Ginseng is Panax Ginseng. It has acknowledge as a natural mysterious cure among the notheastern peoples. because of its broad medicinal application. The origin of the word" Panax" derived from panacea. a Greek word meaning cure-all. According to the classification method of herb medicines in the Chinese medicinal book.

누에고치를 2N HCl 용액으로 11$0^{\circ}C$, 48시간 가수분해한후 중화하여 냉동건조하여 얻는 누에고치 산가수분해물의 아미노산 조성은 glycin이 43.25%, alanine이 34.39%, serine 10.05%, valine이 2.44%였고 필수 아미노산은 7.12% 차지하였다. 누에고치 산가수분해물의 사료이용효율은 카제인과 같았다. 1~5% 실크분말의 첨가에 의한 간의 무게, 간효소활성(GOT, GPT), 혈청알부민, 혈청 총단백질의 함량은 영향이 없어 단백질의 질이 낮은 것으로 평가되었다. 흰주에 고콜레스테롤, 고지질, 고설탕사료를 각각 섭취시키면서 5% 누에고치 산가수분해물을 첨가하였을 때 혈장 지질농도에 미치는 영향은 중성지질의 감소, 인지질과 HDL의 증가 등 혈액지질조정에 바람직한 결과를 보였으나, LDL과 총콜레스테롤을 높이는 좋지 못한 효과도 나타냈다. 그러므로 누에고치 산가수분해물은 단백질 급원 식품으로보다는 이를 이용한 펩타이드의 생리기능 또는 식용 이외의 화장품재료, 의약용재료, 포장제 등과 기타 물리 화학적 특성을 기초로 한 다양한 범위의 응용이 더욱 적합하다고 생각되며, 혈액지질 개선효과에 대해서는 심층적인 연구가 필요하다.

The ZZimzilbang is a room where many women eagerly go due to the special meaning women give to it related to their health. It is a different type of sauna room which maintains low degree of temperature, consisting of an Ondol room(Korean under-floor heating system, hypocaust) built with mineral stone radiating ultrared rays. Even though many women mention that they utilize it for health, there is no precise evidence of the effects on their health. This ethnographic study sought to define the phenomenon from the perspective of the women who experienced the ZZimzilbang. A convenience sample of 27 women was interviewed during a 15 month period from December 1995 to July 1997 in 12 ZZimzilbangs located in Seoul, Korea. The mean ages of the women 57.3 years ; seventeen women were housekeeper and only eight women had job : twenty women were married and three women among them were widows. The main reasons women patronize the place are : for mitigation and healing of physical signs and symptoms : composure ; safe lodging and boarding : control of outward appearance : control of health ; meeting and fellowship with friends : and custom. The outcomes of the utilization of the place were : mitigation of physical signs and symptoms : psychological tranquility : cosmetic and diet ; good use of spare time : and utilization of services provided there. Most women who visited ZZimzilbang for relief of physical signs and symptoms strongly mentioned a correlation to inadequate Sanhujori, the traditional postpartal and postabortal care for woman. Some of specific kinds of services provided in that place were alternative therapy such as acupuncture, negative cupping, finger-pressure, mugwort steam and various kinds of massage including massage of blood vessels that are influenced by Oriental medicine ; health education of breathing such as abdominal breathing or Danjeon(단전호흡) : and selling of many things including health foods, drugs for osteoporosis, and eutrophics. This study suggests that professional caregivers should further study this phenomenon for the development of adequate care of women with a resulting important in their quality of life.

Ultraviolet radiation have much influenced with a deep wrinkles, roughness, laxity of skin damage and pigmentation through oxidative stress and oxidative photo-damage. This study investigates the functional properties of hydrogel facial mask sheets made from agar, Styela clava tunics and Broussonetia papyrifera tunics. The skin of S. clava is covered with a hard cellulose containing glycoprotein, glycosaminoglycan and chondroitin sulfate. B. papyrifera is better known as Paper mulberry. It contains kazinol which serves as a tyrosinase inhibitor and skin whitening agent. The tensile strength of facial mask sheet was measured by universal testing machine, and the water absorption and moisture permeability of facial mask sheet were measured by dryer. Additionally, the DPPH assay and MTT assay were conducted for anti-oxidative activity and cytotoxicity of facial mask sheet. The whitening effect of the facial mask sheet was measured by tyrosinase inhibitor assay. These tests showed that the three ingredients are suitable cosmetic materials. The results reveal that they produce a high quality hydrogel facial mask sheet when the membrane contains 1%(W/V) of agar, 0.1%(W/V) of B. papyrifera tunics and 0.05%(W/V) of S. clava tunics.

Keloid scars are often considered aesthetically unattractive and frustrating problems that occur following injuries. They cause functional and cosmetic deformities, displeasure, itching, pain, and psychological stress and possibly affect joint movement. The combination of these factors ultimately results in a compromised quality of life and diminished functional performance. Various methods have been implemented to improve keloid scars using both surgical and non-surgical approaches. However, it has proven to be a challenge to identify a universal treatment that can deliver optimal results for all types of scars. Through a PubMed search, we explored most of the literature that is available about the intralesional injection treatment of hypertrophic scars and keloids and highlights both current (corticosteroid, 5-fluorouracil, bleomycin, interferon, cryotherapy and verapamil) and future treatments (interleukin-10 and botulinum toxin type A). The reference lists of retrieved articles were also analysed. Information was gathered about the mechanism of each injection treatment, its benefits and associated adverse reactions, and possible strategies to address adverse reactions to provide reliable guidelines for determining the optimal treatment for particular types of keloid scars. This article will benefit practitioners by outlining evidence-based treatment strategies using intralesional injections for patients with hypertrophic scars and keloids.

A high performance liquid chromatography (HPLC) method for the quantitation of ellagic acid in Nymphaea tetragona was developed for the quality control of functional cosmetic ingredient, the extract of N. tetragona. Separation and quantitation were successfully achieved with a Kromasil C18 column ($5{\mu}m$, $250mm{\times}4.6mm$, i.d.) by isocratic elution of a mixture of acetonitrile containing 0.1% trifluoroacetic acid and water containing 0.03% phosphoric acid at a flow rate of 1.0 ml/min. The UV detector was used for the detection and the wavelength for quantitation was set at 254 nm. The presence of ellagic acid in the extract was determined by comparison of retention time and spiking with authentic standard. Analytical results showed good linearity ($R^2=0.99996$) in relatively wide concentration ranges. The R.S.D. for precision test was less than 3.0%. Recovery of the compound was 98.55~101.72% with R.S.D values less than 4.0%. In conclusion, this method has been successfully applied to the determination of ellagic acid in N. tetragona.
