So far there has been a strong tendency to study The Great Learning in terms of quite" limited ethical and moral understandings." Yet The Great Learning was originally a political text to educate the ruler. So the ethical and moral understanding discussed in the book should be interpreted as something more comprehensive and practical, which includes the political ability. This paper thus focuses on this new line of understanding of The Great Learning. Among the three principles of the book, 'Myeongmyeongdeok( 明明德)' means the virtue of a politician, that is to 'cultivate (Myeong)' the 'properties for a statesman (Myeongdeok).' 'Sinmin (新民)' means 'to innovate or reform the people as a result of substantive administration of a politician'. 'Jieojiseon (止於至善)' means 'to reach and to maintain the highest degree of goodness as a result of Myeongmyeongdeok and Sinmin'. These three principles would divide into eight practicums. Myeongmyeongdeok would divide into five steps of 'Sugi(修己: Cultivating the self)' practicum, which are 'Gyeokmul (格物) → Chiji(致知) → Seongeui(誠意)→ Jeongsim (正心)→ Susin (修身)'. Sinmin would divide into three steps of 'Chiin (治人: rule the people)' practicum which are 'Jega(齊家) → Chiguk(治國) → Pyeongcheonha(平天下).' And the point where the two practicums are harmonized, i.e. that of Sugichiin (修己治人), is the place of Jieojiseon. Not every ethical people become a politician but every politician must be ethical. That is the assertion of the Great Learning.

his study was to investigate effects of improvement of balance abilities through 8-weeks Transcutaneous Electrical Nerve Stimulation (TENS) and balance training in the women elderly. 42 women elders who were participated in silver college. Randomized study design of two groups was used: TENS group (21 women, 84.53 years old) and balance training group(21 women, 79.93 years old). Each group had a application of TENS, balance training by a researcher three times per week for 8 weeks. Measurements of static postural sway velocity on the floor and foam, timed get up and go test (TUG), functional reach test (FRT), and lateral functional reach test (LFRT) were evaluated at initial presentation (pretest) and after completion of the each intervention program (posttest). The results showed that the TUG was significantly decreased in all groups (p<.05) and the postural sway velocity using force plate in all conditions was significantly decreased in all groups (p<.05). FRT and LFRT were significantly increased in all groups (p<.05). There were significantly differences in TUG and postural sway velocity on the eye closed condition between two groups (p<.05). In conclusion, the application of TENS to older adults whose somatosensory were deteriorated was effective for improvement balance ability.

A motive and aim of enactment of UN Convention on the Use of Electronic Communication in Int'l Contracts is based on need to eliminate legal obstacles that might arise under existing int'l trade law instruments and promote int'l electronic commercial transaction. But when it is used with related articles, 14, 15, 16, 17 for offer under CISG, one of the most successful conventions which produces substantive law for the unification of int'l trade, questions of practical importance, for example possibilities of withdrawal, revocation, rejection of offer, the extent of its criteria arise from therewith. In conclusion, a effective electronic offer has to assure easily access and confirmation of trade terms besides criteria of offer under CISG. An offer can be withdrawal, if electronic message of withdrawal has entered the offeree's server before or at the same time when the offer has reached the offeree but agreement expressly or impliedly, between the parties about type, format, email address is a prerequisited. Implied consent could be presumed through prior conduct or trade usages between the parties under CISG articles 8, 9. The term "have reached" correspond to the time which is able to retrieve the electronic message of withdrawal. But without express or implied agreement between them about electronic communication of type, format, email address, an offer can be withdrawal before or at the same time when it has entered offeree's other e-mail address and confirmed by his retrieval. In case of the revocation, electronic message of the revocation is effective before the offeree's dispatching an acceptance. A prerequisite for the revocation by electronic communication is came as the above mentioned withdrawal except for concept of a time difference for reach. In case of a rejection of offer, when a rejection by electronic communication has entered the offeror's server, an offer is ended. But a prerequisite for the rejection by electronic message is same as the above mentioned withdrawal and revocation.

Objective: In the present study, the effects of visual restriction and unstable base dual-task training (VUDT), stable base dual-task training (SDT), and on stroke patients' balance and concentration abilities were examined. Design: Two-group pretest-posttest design. Methods: Dual-task training was conducted for thirty persons with chronic stroke who were hospitalized or receiving physical therapy and were randomly assigned to either the VUDT group (n=15) or the SDT group (n=15). The subjects were divided into two groups of 15 participants each, the VUDT group and the SDT group. Dual-task training was administered for 30 minutes per session, three times a week for 8 weeks. The participants' balance was measured via the center of pressure migration distances, functional reach test (FRT), Berg Balance Scale (BBS), and attention was measured using the trail-making test and the Stroop test. Results: In comparisons within each group, the two groups showed significant differences before and after the training (p<0.05). In the comparisons between the groups, the VUDT group showed significant improvements in center of pressure (COP), FRT, and BBS, and TMT compared to the SDT group (p<0.05). Conclusions: It would be more effective to conduct dual-task training as a rehabilitation training program under vision restriction and unstable supporting surface conditions than to conduct the test under unstable supporting plane conditions to improve balance and attention in chronic stroke patients.

Background: The purpose of this study was compare and analyze the flexibility and dynamic balance in adolescents with idiopathic scoliosis and provide scientific basis for effectively treating idiopathic scoliosis. Methods: The subjects of this study were 20 members of adolescences. To measure the flexibility of the spine, a left buckling instrument was used, and it was measured using a modified sit and reach test. They were randomly divided into core exercise with sling program group (n=10) and general exercise program group (n=10), each consisting 50 minutes each for 4 times per week for 8 weeks. Results: The results of the study are as follows. First, Both groups were increased statistically significantly in spinal flexibility but no significant differences have been found between the two groups after 8 weeks of exercise. Second, Both groups were increased statistically significantly in balance ability of dynamic foot pleasure ratio but no significant differences have been found between the two groups after 8 weeks of exercise. Conclusion: In summarizing the results of this study, sling exercise with core exercise was effective in the decrease of flexibility and stability than general scoliosis exercise in adolescents with idiopathic scoliosis. It is also believed to be applicable to spinal diseases caused by muscular weakness since it is effective in strengthening core muscle strength.

Folic acid, one of the B group of vitamins, is an essential substance for maintaining the functions of the nervous system, and is also known to decrease the level of homocysteine in plasma. Homocysteine influences the lowering of the cognitive function in humans, and especially in elderly people. In order to determine the strains with a strong capacity to produce folic acid, 190 bacteria were isolated from various kinds of jeotgal and chungkuk-jang. In our test experiment, JA71 was found to contain $9.03{\mu}g/mL$ of folic acid after 24 h of incubation in an MRS broth. This showed that JA71 has the highest folic acid production ability compared to the other lactic acid bacteria that were isolated. JA71 was identified as Lactobacillus plantarum by the result of API carbohydrate fermentation pattern and 16s rDNA sequence. JA71 was investigated for its physiological characteristics. The optimum growth temperature of JA71 was $37^{\circ}C$, and the cultures took 12 h to reach pH 4.4. JA71 proved more sensitive to bacitracin when compared with fifteen different antibiotics, and showed most resistance to neomycin and vancomycin. Moreover, it was comparatively tolerant of bile juice and acid, and displayed resistance to Escherichia coli, Salmonella Typhimurium, and Staphylococcus aureus with restraint rates of 60.4%, 96.7%, and 76.2%, respectively. These results demonstrate that JA71 could be an excellent strain for application to functional products.

Statistical literacy is a key ability expected of citizens in information-laden societies, and is often revealed as an expected outcome of schooling and as a necessary component of adults' numeracy and literacy. Knowing how important statistical literacy is, the purpose of this research was to measure statistical literacy of adults and secondary mathematics teachers. This study explored the statistical literacy based on the level of understanding in poll results and analyzed the data obtained through semi-structured interviews with 20 secondary mathematics teachers and 20 adults. As a result, the following conclusions were obtained: First, few secondary mathematics teachers and adults correctly recognized the meaning of statistical terms and expressions included in the poll results. Second, 70% of research participants did not reach levels 3 or 4 of statistical literacy levels. Third, the statistical literacy level of secondary mathematical teachers was higher than that of adults.

PURPOSE: The initiation of the trunk muscles in stroke patients is delayed because the muscles involved in reach arm are activated earlier than the trunk muscles. The objective of this study was to examine the effects of mobility, balance, and trunk control ability through selective trunk exercise (STE) in patients with chronic stroke. METHODS: A randomized pre-test and post-test control group design was initially used, with subjects randomly assigned to the STE group (n=15) and a control group (n=14). All groups underwent physical therapy based on the neuro-developmental therapy (NDT) for 30 minutes a day, five times per week for four weeks. Additionally, the STE group did the trunk exercise for 30 minutes a day, three times per week for four weeks. The timed up and go test (TUG), Berg balance scale (BBS), and trunk impairment scale (TIS) were used for assessment. RESULTS: The scores of the TUG, BBS, dynamic sitting balance subscale, and coordination subscale of TIS improved significantly in both groups but the improvement was more pronounced in the STE group (p<.05). This study showed a large effect on the scores of the TIS coordination subscale (d=.93) (p<.05), TIS dynamic balance subscale (d=.81) (p<.05), TUG (d=.75) (p<.05), and BBS (d=.73) (p<.05). CONCLUSION: The combined STE and NDT program showed improvements in measures of mobility, balance, and trunk control in chronic stroke patients. These results suggest that STE should be considered to be included in the treatment program for patients with chronic stroke.

Spatial and temporal variations of environmental factors and phytoplankton community were investigated in the three stations of Andong Reservoir in 1997 and 2003. The changes of physico-chemical water quality and phytoplanktonic biomass were higher in 2003 than that of 1997, due to rainfall difference. The concentration of total nitrogen (TN) and total phosphorus (TP) in the reservoir decreased, but total nitrogen fell relatively more between them. TN/TP ratio decreased from 109 to 90 showing no change at the downstream but a big decrease at the midand upstream. Predominant phylum of phytoplankton in Andong Reservoir were six genus that composed to Anabaena, Aphanizomenon and Microcystis of Cyanophyceae, Cosmarium and Scenedesmus of Chlorophyceae and Synedra of Bacillariophyceae, respectively. Among the observed phytoplankton, diatom Synedra occured as the maximum amount of 3,400 cells mL$^{-1}$ even at the above 30°C. Green algae Scenedesmus observed along with Microcystis. It seemed to be compete with Microcystis during the high water temperature period. Although trophic state of Andong Reservoir was decreased, the standing crops of phytoplankton were increased. Moreover bluegreen algae, Aphanizomenon and Microcystis in the region of upstream to midstream and diatom, Synedra in the region of midstream to downstream were increased until to reach the algal bloom, respectively. It seemed necessary to attention the changes of blue-green algae Aphanizomenon, that has an ability of nitrogen fixation.
