This study provides the policy implication for the actualization of district plan in urban planning system, that has been set up in 2000 urban planning law, by the study of district planning system of Japan' case The district planning system of Japan is divided 5 catagory(district plan in urban planning, urban redevelopment district plan, roadside district plan, village district plan, residential intensive use district plan) in line with individual law. But this study focus on the special implementional tools of the sub level district plan types(general district plan, incentive development district plan, induced density plan for residential use, limited density district plan, TDR type district plan)for the district planning in urban planning of Japan. Japan’s district planning system has been progressed by the incremental steps in consistant with situational contexts. In conclusion, our district plan should be establish its basic foundation which is composed 4 important aspects. First, The local rules and guidelines of district plan is suggested by the scientific research and rational purpose. Second, The diversified incentive merit system be induced for the promotion of district planning. Third, The district plan be implemented by the action program for development which supported by the governmental funds. Fourth, The urban planning database system which be applied 3 dimensional analysis be developed for good district planning.

In this study, we analyzed two types of echolocation calls used by the parti-coloured bat, Vespertilio sinensis. Bats were captured in the Naejangsan National Park in October 2013. Call sounds of hand-released bats were recorded at the location of capture within the National Park. We analyzed pulse duration (PD), pulse interval (PI), peak frequency (PF), maximum frequency (FMAX), minimum frequency (FMIN), and bandwidth (BW). V. sinensis emitted the different types of the echolocation calls depending on the surrounding environment. Frequency modulated-constant frequency (FM-CF) signal of audible range was emitted when they flew in the uncluttered space over the canopy. However, when flying in the cluttered space below the canopy, they only emitted FM signal. FM-CF signal is in the audible range (e.g., low frequency), and FM signal has a harmonic broadband frequency range of two. There were significant differences in PD, PI, PF, FMAX, FMIN, and BW between the calls emitted over and below the canopy. Considering the functional characteristics of FM and CF signals, we conclude that the foraging activity of V. sinensis was observed below the canopy, and recommend the use of FM signal and broadband as echolocation signals.

Purpose: Anesthesia and surgery commonly cause hypothermia, and this caused by a combination of anesthetic-induced impairment of thermoregulatory control, a cold operation room environment and other factors that promote heat loss. All the general anesthetics markedly impair normal autonomic thermoregulatory control. The aim of this study is to evaluate the effect of two different types of propofol versus inhalation anesthetic on the body temperature. Materials and Methods: In this randomized controlled study, 36 patients scheduled for elective laparoscopic gastrectomy were allocated into three groups; group S (sevoflurane, n=12), group L (lipid-emulsion propofol, n=12) and group M (micro-emulsion propofol, n=12). Anesthesia was maintained with typical doses of the study drugs and all the groups received continuous remifentanil infusion. The body temperature was continuously monitored after the induction of general anesthesia until the end of surgery. Results:The body temperature was decreased in all the groups. The temperature gradient of each group (group S, group L and group M) at 180 minutes from induction of anesthesia was 2.5±0.6°C, 1.6±0.5°C and 2.3±0.6°C, respectively. The body temperature of group L was significantly higher than that of group S and group M at 30 minutes and 75 minute after induction of anesthesia, respectively. There were no temperature differences between group S and group M. Conclusion: The body temperature is maintained at a higher level in elderly patients anesthetized with lipid-emulsion propofol.
