Cosmetics market information is important due to advances in information communication technology and the growth of cosmetics market. This study analyzed the relationship between the pre-purchase utilization of information (commercial, neutral, personal and experiential) and the post-purchase satisfaction of skin care cosmetics, categorized as functionality, safety, economic feasibility, information reliability, purchase convenience, condition of purchase place, packaging/design of product and service. This study analyzed reliability, frequency, differences, correlation and regression analysis using SPSS ver. 24.0. The study results are summarized as follows. First, gender was a significant variable in the level of information source utilization. Women used commercial, neutral, and experiential information sources more actively than men. However, women had lower post-purchase satisfaction that could be understood through expectation disconfirmation theory. Women have very high expectations that can lower post-purchase satisfaction. Second, information source utilization can improve post-purchase satisfaction for cosmetics. The consumer post-purchase satisfact the lowest in the commercial information source; however, consumers were satisfied when the commercial informationinformation sourceenon and regre. Third, the consumeried itnformation sourceenon and regression analysis ial, neutral,source and reflected the characteristics of experiential goods. Therefore, companies should provide accurate commercial, personal and experiential information to increase consumervide accurate commercial, per as well as conduct experiential marketing.

Patients with febrile illness and skin rashes need full and immediate attention. In general, these diseases show mild manifestations and good prognosis. However, causalities of some diseases with fever and rash may be life threatening or trivial. So, the differential diagnosis for those patients is extensive. A through history, a careful physical examination and close observation of clinical progress are very helpful and essential to confirming the diagnosis. Histories of recent travel, drug or specific food ingestion, exposure to human or an animal source of infection may be useful to discover the cause. Although laboratory tests can be useful in making the diagnosis, laboratory results usually are not available immediately. Knowledge and experiences of such diseases may be helpful to reduce the differential diagnosis to a few major possibilities. Rashes can be categorized as petechial, maculopapular, vesicular, urticarial and erythematous. Potential causes include infectious pathogens such as virus, bacteria, rickettsiae, spirohetes, connective tissue diseases, allergic diseases and heamto-oncologic diseases. Because the severity of these diseases can vary mild to life threatening, physicians must perform prompt management decisions regarding empirical therapies. In this article, the differential etiological diagnosis of each type rash is reviewed and discussed, and with emphasis on intensive care of life threatening febrile diseases with rashes that are seen in our country.

Now many sustitution and false articles is used in korea instead of mudanpi. To use mudanpi correctly, we will make a quilitative certificational plan of mudanpi to investigate all of lieraturea, records and documents. And we could reach conclusions as folloews. 1. Source Source of mudanpi is cortex of Paeonia suffruticosa Andrews(Family:Ranunculaceae) in korea and china. It needs an attention to distinguish into because there is a substitute and a rank in china. 2. process We have to work before harvesting fresh roots is dry perfectly. If outer skin dried moisture a little, cut off outer skin vertically at sunny day, remove a heart and sever, immedietly dry. When working, we have to take care of because of easy discoloration with moisture. 3. Quality (1) Functional standards A diameter is large, it do not exist a heart of wood, a bark is thick and powdery. Section surface is light white color and rich odor with many light crystals. (2) Physicochemical stamdards We think that it needs to raise a contant of paeonol at all kinds of testing standards. A contant of paeonol is at least more than 2.5%. A part of wood indicate a heart of wood which has no medical effects, but is a relatively heavy part. So a standart of wood must be lowered sifnificantly less than 1.0%. It must be content of ash is less than 6.0%, Content of acid-nonsoluble ash is less than 1.0%. A fixed quantity of paeonol is more than 2.5%. Contens of heavy metal has to detect less than 30 ppm and there is no reminding agriculural medince.

Pulmonary complications occur in 40~60% of patients who receive hematopoietic stem cell transplantation (HSCT) and are a source of substantial morbidity and mortality. Acute eosinophilic pneumonia (AEP) is an uncommon, non-infectious pulmonary complication occurring in HSCT recipients. We now report the case of a 52-year-old man with AEP who was treated with allogenic HSCT due to acute myeloid leukemia. He complained of fever, cough and dyspnea 390 days after allogenic HSCT. He also had skin and hepatic graft versus host disease (GVHD). Hypoxemia, diffuse pulmonary infiltrates on a chest x-ray and eosinophilia in bronchoalveolar lavage fluid were also noted in several tests. His symptoms, pulmonary infiltrates, hepatic dysfunction and skin lesions rapidly improved after treatment with corticosteroid therapy. Our case supports the idea that AEP is a late phase non-infectious pulmonary complication and one of the manifestations of chronic GVHD.

Intense pulsed light(IPL) is a photo-therapeutic medical device using xenon lamps with optical characteristics of incoherence, defocusing, and polychromatic. IPL has been recognized as a representative medical therapeutic device with growth of domestic skin care market. However, there is no standard regulation manual and guideline to evaluate the safety and performance of IPL. International Electrotechnical Commission(IEC) is being statued "Technical Report IEC TR 60825-16" which is a guidelines for the safe use of intense light source equipment on humans and animals. In this study, a standard Korea Food & Drug Administration (KFDA) regulation for the safety and performance of IPL was suggested by developing minimal evaluation methods for optical parameters of IPL such as output energy density, pulse mode, spot size, wavelength and uniformity of output light. We expect that this study may be a step to statue a standard regulation manual and guideline for IPLs used in domestic.

This research was to investigate the inhibitory effects of tyrosinase, elastase and collagenase using rapeseed meal extract for the functional cosmetics. Gamma-tocopherol and alpha-tocopherol contents were 304.9 and 212.2 mg/kg, respectively. In the case of delta-tocopherol and plastochromanol-8, they were 12.1 and 35.7 mg/kg, respectively. The total phenol content of methanol extract was the highest (49.6 mg/g) which was about 4.96 fold higher than that of water extract. The maximum nitrite scavenging activities of methanol and acetone extract at pH 1.2 were 85.2 and 80.1%, respectively, at 8.0 mg/mL. When the extract concentration of rapeseed meal increased upto 2.0 mg/mL, cell viabilities did not appear to have any significant cytotoxic effect, irrespective of extracts. Tyrosinase and elastase inhibition activities increased from 25.2 to 42.5% and 25.3 to 48.0%, respectively, as methanol extract concentration increased from 0.5 to 1.0 mg/mL. The collagenase inhibition activities of methanol and acetone extracts at 1.0 mg/mL were 67.2 and 68.0%, respectively. These results showed that the methanol and acetone extract of rapeseed meal can be used as a new source of functional cosmetic agent.
