  • The effects of unripe apple mask pack made from unripe apple extracts on the skin status of middle-aged women for 4 weeks were investigated. The subjects were divided into three groups: placebo mask pack as the control (PM, n = 8), apple mask pack (AM, n = 16), and apple mask pack + apple intake (AAM, n = 12). The study included a survey questionnaire, and evaluations of nutrients intakes and of skin status. Skin status was measured by Aramo-TS. After 4 weeks, facial moisture, elasticity, evenness, and wrinkle level were improved in AM and AAM. The facial moisture level (AM: $+3.13\;{\pm}\;2.73$, AAM: $+2.25\;{\pm}\;2.93$) and elasticity level (AM: $+5.81\;{\pm}\;8.27$, AAM: $+5.50\;{\pm}\;6.13$) of AM (p < 0.001) and AAM (p < 0.05) were increased. The facial evenness level (AM: $-5.25\;{\pm}\;8.13$, AAM: $-9.17\;{\pm}\;4.26$) and wrinkle level (AM: $-10.88\;{\pm}\;11.74$, AAM: $-17.83\;{\pm}\;12.22$) were significantly decreased. AAM was more effective in improving skin elasticity, evenness, and wrinkle. The skin status of PM was not changed. While the macronutrient intakes of all the subjects were not different before and after the study, the daily intakes of some vitamins (vitamins $B_6$, C, and E and folic acid) during the study were significantly increased in AAM. These findings suggested that regular use of apple mask pack was effective in improving overall skin status. Furthermore, the consumption of apples with mask pack application was much better in improving skin status.

  • Deep sea water is found more than 200 m under the surface. As no sunlight reaches, no photosynthesis takes place, and it has very little organic matter or bacteria. In addition, deep sea water maintains a consistently low temperature throughout the year, and it does not mix with the water found closer to the surface, which means that its cleanliness is preserved. It is a long-term mature sea water resource that is rich in minerals. This paper examined the physical characteristics and the uses of deep sea water, a subject that has been attracting a great deal of public attention recently, together with the current status of domestic research into it and the direction of research in the USA and Japan, focusing on the existing literature. The aim of this paper was to provide are source to researchers in the field. Since the 1970s, scientists around the world have recognized the importance of deep sea water, and have been conducting research into it. In the USA, deep sea water has been researched with the view of its application to cooling, alternative energy, farming, and the development of new materials. In Japan, about 10 local self-governing bodies are currently promoting research and business relating to deep sea water, which has resulted in a number of products that have been released to the market. In Korea, the ministry of land transport and marine affairs has been studying deep sea water since 2000, and full-scale national R&D projects have been performed by 24 organizations, including KORDI, through industrial/academic cooperation. Large companies are participating in deep sea water research projects in several ways. A study of data foundusing NDSL relating to domestic studies of deep sea water found 50 theses, 177 domestic patents, 6 analyses, 2 reports, and 2 etc. in other areas.

  • The work described in this paper deals with the proposed application of an Artificial Neural Network Model for the Advanced Pressurized Water Reactor APR-1400 transient identification. The approach adopted for testing the network take note of the expectation which should be fulfilled by a network for real-time application, like testing with data in on-line mode and use of actual or real-life patterns for training. The recall test performed demonstrates that use of neural network for transient identification is indeed an attractive preposition.

  • The inability of the management information systems (MIS) field to progress as a scientific discipline has been attributed to the lack of systematic research and a cumulative tradition, an identity crisis, and the poverty of scientism. While research on the status of MIS is very important in order to enhance the field as a scientific discipline, few have investigated this issue. Following Thomas Kuhn's idea of paradigm, this paper studies other fields to investigate when they progressed, when they did not, and why. After research paradigm was broken down into technology-push and demand-pull types, a model on the science life cycle was developed in an effort to explain the path how a science has progressed. A test of this model in the fields of physics and chemistry with an old historial background reveals that the scientific progress in the area of demand-pull is more desirable if this progress turns out to be in the right direction. An application of the model to the MIS field shows that the research paradigm in this field is mainly of technology-push. In order to shift this paradigm toward the demand-pull area, this paper suggests the research on the relationship among MIS subfields and the adoption of appropriate reference disciplines.

  • Background: Increased oxidative stress and inflammation play a critical role in the etiopathogenesis of chronic tendinopathy. Melatonin is an endogenous molecule that exhibits antioxidant and anti-inflammatory activity. The aim of this study was to evaluate the biochemical and histopathological effects of exogenous melatonin administrations in supraspinatus overuse tendinopathy. Methods: Fifty rats were divided into the following four groups: cage activity, melatonin treatment, corticosteriod therapy, and control. Melatonin (10 mg/kg, intraperitoneal; twice a day) and triamcinolone (0.3 mg/kg, subacromial; weekly) were administered to the treatment groups after the overuse period. Biochemical and histopathological evaluations were performed on serum samples and biopsies obtained from rats. Plasma inducible nitric oxide synthase (iNOS), vascular endothelial growth factor (VEGF), total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) levels were evaluated biochemically. Results: The TAS, TOS, OSI, iNOS, and VEGF values were significantly lower than the pre-treatment levels in rats receiving exogenous melatonin treatment (3 or 6 weeks) (p<0.05). TOS, iNOS, VEGF, and OSI values after 3 weeks of triamcinolone administration, and TOS, VEGF, and OSI levels after 6 weeks of triamcinolone application, were significantly lower than the pre-treatment levels (p<0.05). Conclusions: Exogenous melatonin application in overuse tendinopathy reduces oxidative stress and inflammation. Melatonin might be an alternative potential molecule to corticosteroids in the treatment of chronic tendinopathy.
