Dietary guidelines are a distillation of dietary advice from health professionals to the general public. They are based upon current scientific knowledge about the relationships between diet and disease, nutrients available in the food supply of a country, and the profile of morbidity and mortality in that country. With two different sets of dietary guidelines used for more than an decade in Korea. the necessity of revising dietary guidelines has been raised continuously from academia and research. Funded by a grant from the Health Technology Planing and Evaluation Board. Dietary guidelines for each age group were drafted as a research project and the one for the Korean elderly is as follows: Dietary Guidelines for the korean elderly(draft) - Have a variety of easily digestible foods on time; at least 3 meals a day and some snakes. - Be physically active to maintain appetite and/or ideal body weight. ; maintain a balance between activity and what you eat. -Increase consumption of bean-and dairy-and dairy-products. - Consume enough amounts of fresh dark-green and yellow vegetables and fresh fruits. - Consume adequate amounts of assorted kind of animal foods including fish, meat and poultry. - If you drink alcoholic beverages, limit your intake and, drink enough water and other averages; alcohol may interact with your medication and affect your appetite. Aforementioned draft and related contents are expected to be utilized as a neat base in formulating(or revising) dietary guidelines for Korean by the Government in near future.

MDH and LDH isozymes of various tissues of serveral snakes which belong to Colubridae, Crotalidae and Viperidae were studied. MDH isozymes were appeared as two bands in all species. Four LDH isozymes were found inall species of Colubridae, Crotalidae and Viperidae. LDH isozymes of muscle and liver had fundamentally the same pattern. On the other hand, there were two LDH isozymes in the heart of all species and the pattern of heart LDH isozyme was reverse of the pattern in muscle. The pattern of LDH isozymes of stomach tissue can be thought as the same pattern with that of heart in all species, but in the stomach tissue of Crotalidae and Viperidae there were four LDH isozymes.

This study explored the case of sandplay therapy for a 4th grade girl suffering from selective mutism. Her selective mutism apparently began following an extremely embarrassing experience in kindergarten. Her symptoms were a combination of symbiotic, reactive and passive- aggressive type behaviors. The goal of the therapy undertaken with this child was to enable her to express her repression and suppression, within a free and protective space during sandplay therapy. There were a total of 60 sessions of sandplay therapy. The client described the situations she had experienced in the first sandtray, by placing babies absent caring adults and food on the sandbox. She also placed baby fish away from their mother. In the mid-point of the sessions, she repeated her regressive behaviors by babbling like a baby and fought with snakes and monsters. In the final sessions, she showed integration and adaptation by engaging in snow play, expressing the union of opposites, placing blue and red mig and making a cross on the sand. This study showed the effectiveness of sandplay therapy since her selective mutism was lessened.

In this paper, the design and analysis of a reconfigurable modular structure, which reforms itself according to the change of the environment and realize appropriate forms and motions, are dealt with. This modular is a free structure from the restrictions with constraints about fixed environment and has various forms and motions by combining units. The form of this unit has a shape of a square with 7 centimeters side each, and has a structure which can be combined in a chain-shape or a lattice-shape. Additionally, The structure has a mobility by being equipped with wheels so that it can be combined for itself. In this paper, all the wireless controllers, sensor system, and communicating method between modules according to module structures were suggested and transformation method to be transformed to shape of snakes, caterpillars were presented. Moreover, simulations for each method were performed to show the validity of the motions including motor torque analysis. All the motions suggested were realized and experimented, whereby the availability of the designed mechanism and algorithm was verified with the result of experiments.

A 29-year-old Korean woman visited the Department of Surgery in MizMedi Hospital with a palpable itching mass on the right breast that had existed for the past 7 months. She had no history to eat either frogs or snakes, but had the history of drinking impure water. Sonography revealed a serpiginous hypoechoic tubular structure associated with partial fat necrosis in breast parenchymal layer and subcutaneous fat layer. It also revealed oval cystic lesions. At operation, an ivory white opaque ribbon-like worm that measured 16.5 cm in length and 0.5 cm in width was extracted. Anti-sparganum specific serum IgG level in the patient's serum (absorbance ＝ 0.71), measured by ELISA, was found to be significantly higher than those of normal controls (cut off point ＝ 0.21) . Sonography and ELISA appear to be helpful to diagnose sparganosis. Breast sparganosis is rarely found throughout the world.

Reptiles were known to serve as paratenic hosts for Centrorhynchus (Acanthocephala: Centrorhynchidae) in Korea, but the infection course in experimental animals was not elucidated yet. In this study, the tiger keelback snakes (Rhabdophis tigrinus) were collected and digested with artificial pepsin solution, and the larvae of Centrorhynchus were recovered from them. Then, the collected larvae were orally infected to rats for developmental observations. In rats, all the larvae were observed outside the intestine on day 3 post-infection (PI), including the mesentery and abdominal muscles. As for the development in rats, the ovary of Centrorhynchus sp. was observed at day 15 PI, and the cement glands were 3 in number. Based on the morphological characteristics, including the arrangement of proboscis hooks, these larvae proved to be a species of Centrorhynchus, and more studies were needed for species identification.

Sparganosis is a rare parasitic disease caused by migrating plerocercoid tapeworm larva of the genus Spirometra. Infection in humans is mainly caused by the ingestion of raw or inadequately cooked flesh of infected frogs, snakes, and chickens. Here, we report a rare case of a 45-year-old man who was admitted to our hospital with left lower chest pain. The chest radiograph and computed tomography (CT) scan revealed localized pleural effusion in the left lower lobe; further, peripheral blood eosinophilia and eosinophilic pleural effusion were present. Percutaneous catheter drainage was performed, which revealed long worm-shaped material that was identified as a sparganum by DNA sequencing. The patient showed clinical improvement after drainage of the sparganum. This study demonstrates the importance of considering parasitic diseases in the differential diagnosis of eosinophilic pleural effusion.

Nature is one of the most important sources of pharmacologically active compounds in the search for drugs against life threatening diseases. Even though plants and terrestrial microorganisms have played as an important source for the new drug candidates from nature, marine organisms such as tunicates, sponges, soft corals, sea horses, sea snakes, marine mollusks, seaweeds, nudibranches, sea slugs and marine microorganisms are increasingly attracting attention in recent years. Marine organisms also have the potential to develop into future drugs against important diseases, such as cancer, a range of bacterial and viral diseases, malaria, and inflammations. Even though the mechanism of action in the molecular level of most metabolites is still unclear, the mechanisms by which they interfere with the pathogenesis of a wide range of diseases have been reported. The knowledge of this is one of the key factors necessary to develop bioactive compounds into medicines. This is due to their structurally unique and pharmacologically active compounds. The potential pharmaceutical, medicinal and research applications of some of these compounds are discussed in hundreds of scientific papers, and are reviewed here.
