Wheat mutants generated from a cultivar ``Geumgangmil"by using a $^{60}$Co source (gamma-ray) were developed for bentazone (3-isopropyl-2,1,3-benzo-thiadiazin-4-one-2,2-dioxide) resistance. Resistant M$_2$ plants were selected from seedlings and adult plants consecutively. Bentazone-resistant wheat plants were able to survive at up to 10 times (1,600 ppm) the commercially recommended concentration. The four plants with the highest bentazone resistance were selected. An AFLP (amplified fragment length polymorphism) analysis was applied to identify molecular markers for bentazone-resistant wheat mutants. Twelve polymorphic products, which were unique to bentazone-resistant plants, were identified, cloned, and sequenced. Among the twelve polymorphic bands, eight Sequence-tagged Sites (STS) primer sets were designed. Only one STS primer set (HRMW-08) was converted a ``Bentazone-resistant wheat-specific" STS marker. The wheat mutants and markers that we obtained could be employed in a cross-breeding program incorporated with marker assisted selection (MAS) in the early stages of population segregation.

The direct reaction method has been used for the fabrication of Al-Mg/Al₂O₃functionally gradient materials. It was found that the reaction layer of the Al-Mg/Al₂O₃powder compact at 900℃ under air atmosphere led to the formation of reaction layers with varying ceramic phase contents. As the results of experiments by using the TGA system, the characteristics and growth behavior of the reaction layers were affected by the reaction temperature, the gas flow rate, the Mg contents and the Al₂O₃contents.

Undergraduate freshmen are currently encountering numerous difficulties in adapting to college life due to the outbreak of the COVID-19 pandemic. Thus, several studies have underlined the need to develop interventions focused on undergraduate students' resilience during this situation. We adopted the service design method in identifying the difficulties faced by undergraduate freshmen during this pandemic, and also developed interventions for raising their resilience. The service design method is a person-centered approach which adopts the user's viewpoint in developing solutions, thereby enabling their requirements to be satisfied. Surveys and in-depth interviews revealed that undergraduate freshmen were experiencing psycho-emotional problems which were derived from schoolwork and college life. This is particularly the case with students who are experiencing greater levels of academic difficulty, and were insufficiently equipped with resources such as stress-coping strategies and social support. Four undergraduate freshmen were recruited online to test the effectiveness of a resource promotion program aimed at enhancing their resilience. This program has proved to be helpful in relieving daily/academic stress and in building relationships among freshmen, regarding which the participants showed a high level of satisfaction. The results were discussed by focusing on psycho-emotional difficulties and resources of college freshmen, as well as the effectiveness of the resource promotion program. Further research is required in order to verify the efficiency of the program and to confirm conclusions.

IR classified by wavelength three parts NIR, MIR. FIR. There is FIR which is radiated from healthy human body the wave length is 8-14m. The Sun's ray is composed of Infared(49%), Visible light(40%) and Ultra violet(11%), however the ray getting to the earth is FIR(60%), IR(20%), and UV(20%). Human beings has utilized FIR already from time immemorial. Hershel found out Infrared for the first time, in the Industrial Revolution the Infrared and FIR had been begun to use making products. FIR with low temperature can deeply penetrate on the human body composed things without troublesome, since FIR has effectively operated on the human body at low temperature (35-40 $^{\circ}$C). In this study, we experimented in the specific temperature FlR radiation intensity. water consumption rate, feed consumption rate. survival rate and mean of weight balance with FlR radiation instrument. According to the results, the FlR radiation to the mice assisted to increase the survival rate.

OBJECTIVE: This study was Far infrared(FIR) irradiating to a rat collagen-induced autoimmune arthritis and observed nitric oxide level of spine. METHODS: Type II collagen(CII) in adjuvant was injected into rats on day 0. The results showed that rats injected with CII plus adjuvant had signs of autoimmune arthritis on day 14. Thereafter, Far infrared(FIR) irradiation was begun on day 15. The rats were irradiated FIR twice per day for 20 min each time. RESULTS: Seven days later(Day 22), the level of NO at FIR irradiated group(FRG; Arth+FIR) was decreased more than FIR-non irradiated group(FNRG; Arth). Twenty-one days later(Day 36), the level of NO at FRG was more closed to the control group's NO level than the FNRG. CONCLUSION: These results indicated that Far infrared irradiating appears to reduce the nitric oxide level at a rat model of autoimmune arthritis induced.

Background: Rabies is an acute fatal viral disease generally transmitted from infected animals to humans through bites. It is distributedworldwide. The number of Korean people traveling to rabies-endemic countries and being bitten by infected animals has beenincreasing recently. Therefore, we investigated international travelers who received rabies post-exposure prophylaxis (PEP) at the NationalMedical Center (NMC) and compared the data with those of other clinics. Materials and Methods: This study was a retrospective review of 106 patients who visited the International Travel Clinic of the NMCand received rabies PEP between July 2006 and December 2012. During that period, we used the Essen intramuscular regimen protocol. Complete rabies PEP was defined as 5 doses of rabies vaccination with or without rabies immunoglobulin (RIG) administrationaccording to the World Health Organization guidelines. Results: A total 106 cases documented within the period of 6 years were selected, including 10 children younger than 15 years and96 older than 15 years. The mean age of the patients who received PEP was 33.4 years. Of the patients, 53 were male and another53 were female. Most of the exposures occurred in Southeast Asia, predominantly from dog bites (71, 66.9%). The lower extremitieswere the most frequent site of exposure (37, 34.9%). All the patients began receiving rabies vaccination for prophylaxis after exposure,and 51 received rabies vaccination with RIG. Meanwhile, 74 cases (69.8%) initiated rabies vaccination overseas, but only 10 of themreceived RIG while overseas; the remaining 32 (30.2%) initiated rabies vaccination after returning to Korea. Within 7 days, all thechildren and 74 adults received their first rabies vaccination. Six adults initiated first rabies vaccination after 1 week. Eleven of the 106patients stopped PEP before 5 doses, among whom 4 (1 child and 3 adults) discontinued vaccination after confirming that the bitinganimal remained healthy throughout 10 days of observation. None of the patients had been previously vaccinated against rabies. Conclusions: Most of the overseas travelers who visited our clinic after being bitten by suspected rabid animals received appropriaterabies PEP. However, the interval between exposure and first rabies vaccination was often delayed. Tourists who planto travel in rabies enzootic regions need to be aware that prompt initiation of PEP is important to reduce the risk for developinghuman rabies.

The purpose of this study was to observe the effects of Far-infrared on mice rheumatoid arthritis induced by type II collagen. The author peformed several experimental tests which were the hematoxylin-eosin tissue stain, the hind paw thickness, and ELSIA of cytokines(TNF-$\alpha$, IL-1$\beta$). On day 14 and 21, FIR-Tx. group decreased in synovial membrane thickness more than control II group FIR-Tx group decreased in hind paw thickness more than control II group. In the ELISA test of TNF-$\alpha$ concentration, control II group significantly increased in the concentration more than normal and FIR-Tx. group on day 7, 14, and 21. In the ELISA test of IL-$\beta$ concentration, FIR-Tx. group decreased in the concentration more than control II group on day 14 and 21. With J's Linear Function Data Process Program, researchers can get the estimated the concentration or the hind paw thickness from this experiment. The estimated results would be a good guide to therapists and researchers, planning Far-infrared application on the rheumatoid arthritis. These results indicated that far-infrared irradiating appeared to reduce the concentration of TNF-$\alpha$ and IL-1$\beta$ at mouse model of autoimmune arthritis. It would be considered that Far-infrared has an effect on relieving rheumatoid arthritis.

Hershel found out Infrared for the first time, in the Industrial Revolution the Infrared and FlR had been begun to use making products. FIR with low temperature can deeply penetrate on the human body composed things without troublesome. since FIR has effectively operated on the human body at low temperature (35-40$^{\circ}$C). When FIR penetrated on the human body, it would inhibit the abnormal genes and cells expression, and then information of DNA and RNA would be reexpressed for arranging DNA and RNA abnormal state. As FIR's receptors in the body, it colud be presumed that N-glycosyl linkage of purine and deoxyribose, RNA splicing process. and Heat shock protein. To radiate optimized FIR, in this study, we made the FIR radiation compound and instrument for unharming biological things. According to the results, the FIR radiation to E. coli., it did not induce genetic mutations and change the survival rate of E.coli.
