Purpose: We intended to observe the relations between Chiljehyangbuhwan and abdominal & palmar temperature according to primary dysmenorrhea severity. Methods: We selected the 100 primary dysmenorrhea patients by the screening tests (first screening test-inquiry, second screening test-clinical test. additionally WHR (Waist-to-Hip ratio) by Inbody 2.0). By the fixed blocked randomization and double blind method, Chiljehyangbuhwan or placebo was administered for 1 menstration period. Finally, 69 patients remainded. Before and after administration, we measured 4 points abdominal temperature (Chon-jung (CV17), Chung-wan(CV12), Kwan-won(CV4). Chung-guk(CV3)) by DITI(DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV12/CV17 and CV4/CV17 and CV3/CV12 and CV4/CV12 and CV3. Also, we measured 2 points (palmar region, upper front of forearm) for the difference of palmar temperature $({\Delta}T)$. Then, we checked palmar temperature minus upper front of forearm temperature and took an average of right and left ${\Delta}T.$ After that. we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by VRS (verbal rating scale) and MVRS (multidimensional verbal rating scale). In dysmenorrhea severity. we standardized scale score and 3-group-severity by score (mild, moderate. severe). Besides, we compared palmar ${\Delta}T$ with abdominal ${\Delta}T$. For statistics, we used ANOVA and Spearman's rho correlations. SPSS 13.0 for windows. Results: In case of MVRS, though Chiljehyangbuhwan was correlated to abdominal ${\Delta}T$(CV12 and CV3/CV12 and CV4). it was not correlated to palmar ${\Delta}T$. In case of VRS, though Chiljehyangbuhwan was not correlated to abdominal ${\Delta}T$. it was correlated to palmar ${\Delta}T$. However. palmar ${\Delta}T$ was not correlated to abdominal ${\Delta}T$. Statistically they showed significant result (p<0.05). Conclusion: The primary dysmenorrhea patients showed that severity by MVRS was connected with abdominal ${\Delta}T$ (CV12 and CV3/CV12 and CV4) and severity by VRS was connected with palmar ${\Delta}T$ after Chiljehyangbuhwan administration. So we can consider Chiljehyangbuhwan partially effects the abdominal & palmar temperature according primary dysmenorrhea severity. However, palmar temperature was not correlated to abdominal temperature. Therefore, we need further study.

In this study we evaluated genetic divergence among six Tongil-type rice varieties and assessed the relationship between genetic distance and hybrid performance in all possible non-reciprocal crosses between them. The 15 F1 hybrids along with the six parents were evaluated for eight traits of agronomic importance including yield in a replicated field trial. The six parents were examined for DNA polymorphism using 120 random decamer oligonucleotide primers. A total of 168 polymorphic variants were generated and based on the polymorphism data, genetic distances (GDs) ranged from 0.157 to 0.383. Heterosis was observed in hybrids for most of the traits, and yield exhibited the highest heterosis among the eight traits examined. The correlation values of GDs with F1 performance were not significant. Also the correlations of GDs with midparent and better-parent heterosis were not significant except for spikelets per panicle. Our results have indicated that GDs based on the RAPDs markers may not be useful for predicting heterotic combinations in Tongil-type rice and are supportive of the idea that the level of correlations between hybrid performance and genetic divergence is dependent on the germlplasm employed.

When open reduction of maxilla fractures is postponed due to concurrent life-threatening injuries, delayed union may result with malunion or nonunion. If delayed malunion is occurred, significant facial deformity may result, including a dished-out face, irregular retromaxillism with Angle's class III malocclusion, open anterior bite, nasal collapse, telecanthus and malar flattening. The treatment planning for this problem includes cephalometric evaluation anterior and lateral tomograms, dental casts, orthodontic planning, dental planning and use of impression tray to rupture the fibrous tissue casts, orthodontic planning, dental planning and use of impression tray to rupture the fibrous tissue attachment at the fracture site. In this paper, one case presented a 58-year-old female patient with maxilla retrusion after comminuted fracture, who was treated with orthodontic methods of maxillary protraction headgear and Plaster headcap, whereas the other two cases were about male patients who were treated principally with surgically open reduction or Le Fort I-controlled transverse osteotomy with iliac bone graft.

This study was undertaken to prolonging the freshness in Squid(Todarodes pacificus) on the effects of ice storage methods(tap water ice, electrolytic water ice) using stainless diaphragm electrolytic instrument and also test an efficiency of instrument. Basically, stainless diaphragm electrolytic instrument studied for changes of pH on difference water flow and ampere. The lower water flower and higher ampere made low pH on acid part of electrolytic instrument. Squid samples were stored in tap water ice, acid part of electrolytic water and base part of electrolytic water and used in studying the changes of VBN and skin color through storage. Acid water had strong sterilization effects and VBN was lower levels of acid water than the others. Base water had not sterilization effects. Tap water ice storage was more sterilizing effects than base water ice storage but less effects than acid water ice storage. Lightness of Squid skin showed getting decrease at storage of ice water of all storage methods but acid water ice storage showed more retarding than the other two storage. From these results, it could be suggested that acid electric water ice storage is effective in extendance the shelf-life of squid at chilled storage.

This study was carried out to develop new cultivars using the $T_5$ generation of transformed rice by PCR analysis with DNA marker in each generation $(from\;T_3\;to\;T_5)$. In the previous study, we successfully developed the transgenic rice plants over-expressing the Arabidopsis $H^+/Ca^{2+}$ antiporter CAX 1 (accession no. U57411) gene. The calcium concentration in brown rice of transgenic plants was higher than that of donor plants, Iipum, and was selected 3 lines out of 25 lines at cultured GMO field. The major agronomic traits such as culm length, panicle length and panicle number of 3 lines at transgenic plants $(T_5)$ were similar to wild type. Also these lines appeared to have disease resistance to rice blast, cold resistance as compared with donor types. The grain shape was similar to donor plant, however, the 1000 grain weight of brown rice was different from transgenic plants. These finding would be used for basic data of new variety registration.

The importance of genetic stability and bio-safety in the environment has recently been recognized for many (genetically modified) GM plants. This study evaluated the GM safety of transgenic rice and its environmental variance. Data on agronomic characters and principal component were collected for vitamin A-enriched GM rice and four check cultivars in a large GM field trial during 2009-2011. The cultivation environment was a large GM field and a greenhouse. In this experiment, there was no significant difference between the agronomic characters of the GM rice and those of a donor plant, 'Nagdong'. In terms of grain characteristics, the appearance and physicochemical characteristics of the GM rice and those of the donor plant were similar. However, the grain of the GM rice developed a white core and a white belly when planted in the greenhouse. The type and distribution of dominant weed species were not different in the GM rice and the 'Nagdong'. In addition, gene flow was not detected in the dominant weed species based on PCR analysis.

Fungi are a major cause of cultural and biological degradation in museum storages and archives libraries. In addition, fungi produce toxins and can cause skin allergies. In particular, fungi coming into contact with the skin through the hands of administrators dealing with cultural properties, archives, and books can lead to secondary infections. To prevent this, applying hand sanitizer, which is readily available in the market, is recommended. However, such hand sanitizer can effectively disinfect against bacteria but not fungi. As such, researching for an alternative is required. In this study, we developed a hand sanitizer composed of active ingredients - geranial, cineol, menthol, and Chamaecyparis obtusa - and performed a disinfection test, which targets 10 kinds of species (Alternaria citrimacularis, Alternaria consortialis, Aspergillus niger, Aspergillus versicolor, Cladosporium sphaerospermum, Coniothyrium aleurites, Penicillium brevicompactum, Penicillium corylophilum, Penicillium paneum, and Penicillium polonicum), of fungi investigated in museums and libraries. It was then confirmed to exhibit excellent disinfecting effects. Thus, this hand sanitizer is expected to prevent skin diseases and secondary infections in administrators dealing with cultural properties, archives, and books.

This experiment was conducted to find out the critical competitive period and competitive ability of rice against red rice. Plant height and number of tillers of rice decreased as red rice competed with rice during active tillering stage. The maximum tillering stage of rice competed with red rice became about 10days earlier than those non-competed. Significant yield reduction of rice was observed in the plots competed for 20 days after transplating or longer. Such a yield reduction can be mainly attributed to the decrease in number of panicles per hill and grain number per panicle. In a replacement diagram for rice and red rice, their competition is turned out being antagonized. The relative yield total was considered lower than 1. Grain number, culm and panicle length of rice was not affected significantly by inter-specific competition. Rice grain yield reduction was highly correlated with the number of panicles of red rice. Three hundred panicles/$m^2$ of the red rice were necessary to reduce rice grain yield by 50% of the check plot.
