This study investigates fitness of horizontal alinement design elements that has been used in Korea. Those elements are analyzed in consideration of road environment, drivers' characteristics, and traffic condition. In addition, reformed superelevation formula is produced to be fit to the conditions in Korea by considering horizontal alinement design elements on the base of 'AASHTO'. The results are summarized as follow 1. According to drivers' cognition analyzed by Factor analysis, drivers regard that road safety and horizontal alinement elements are the most important facts. 2. Superelevation value which is produced from radius of road curve in research area is shorter than standard superelevation value. Therefore, we should revise and supplement the standard superelevation in aspect of drivers' safety. 3. Superelevation value analyzed by 85 percentile running speed shows higher value than critical superelevation value used in Korea. So, we should upgrade the critical superelevation value.

북한 테러지원국 해제 이후 북핵 전망 및 우리의 대응방향

임채홍 원광대학교 2008 圓光軍事論壇 Vol.- No.4

NK's nuclear issue has double-faceted nature, e.g., an international or a regional issue related to nuclear proliferation and a domestic issue to pose security threat to the Korean peninsula. Recently, disablement process as regards the NK's nuclear facilities has resumed soon after the US State Department announced to remove NK from the list of state sponsors of terrorism. But considering a variety of future issues challenging SK & the US, it is merely a signal that the controversial long journey would begin before long. After terminating disablement, NK will try not to implement or to defer its further obligation if possible on the basis of typical salami tactics making use of forced insistence, unreasonable interpretation, blackmail, etc. It is since NK's nuclear program and its possession of nuclear weapons are useful vehicle of the last resort for its regime survival and sustainability. Reviewing the process of the six party talks, it could be said that there was not much solid ties and concerted cooperation among five parties except NK thanks to national security interests of individual country. In this context; SK should bear in mind following response measures in order to achieve NK's denuclearization successfully through the six party talks on the basis of the CVID(comprehensive, verifiable, irreversible dismantlement) principle. First, SK should continue to maintain six party talks having been lasted so far since 2003, and develop it to more substantive negotiations. Second, SK needs to highlight the role of China and Russia to create nuclear weapons-free NK. particularly through China's intensive pressure to NK. Third, SK ought to continue to attach importance to the CVID principle vis-a-vis NK's nuclear program and nuclear weapons involving the UEP(uranium enrichment program). Fifth, SK should strengthen ROK-US allied relations to stabilize possible military tension between the two Koreas, simultaneously cooperating with the next US government to place NK's nuke issue in the priority. Lastly, SK needs to prudently take into account the alternative plan to provide thermal power plants or whatsoever to NK in lieu of the LWR(Light Water Reactor) to block even the least feasibility able to produce plutonium. In conclusion, It would be essential for the five parties except NK to move forward to the same direction so as to establish denuclearized NK, taking advantage of aforementioned various strategic measures, and further to make NK be a responsible state of the international community, at the earliest date, complying with international nonproliferation norms, NPT and IAEA safeguards.

The main purpose of this study is to analyze the effect of depth jump shocking "super quality training ; SQT" programme for improving leg power performance of volleyball players. 9 male players were selected out of the volleyball players in KPU. The experiment was focused on jumping height, speed and repetitive jumping speed in the take-off in box drill dropping performance, various articles have reported that, during the take-off jump, exterior muscles at the beginning fulfill both work(the phase of amortization) and later overcoming work(phase of active take-off). Therefore, in the experiment the subjects were required to keep their both legs upward after the plumb-line jump from the box 50∼70㎝ height. The landing area was conditioned with jumping board(amortization phase) During the 8 weeks of experiment, the trading was regularly enforced once per day, 4 or 5 times frequence a week, the data statistically obtained were analyzed, the results of which are as follows : ① Blocking jumping height The performance of exp. subjects was greatly improved after experiment. The increase of blocking jumping height in the exp. subjects was 3.9㎝∼6.4㎝(6.5%∼12.8%). The values of all items were statistically significant at 0.001 level. ② Blocking jumping speed The performance of exp. subjects was greatly improved after experiment. The increase of blocking jumping speed in the exp. subjects was 20㎳∼170㎳(4.0%∼10.9%) The values of all items were statistically significant at 0.001 level. ③ Blocking repetitive jumping speed The performance of exp. subjects was greatly improved after experiment. The increase of blocking jumping speed in the exp. subjects was 360㎳∼1040㎳(6.1%∼10.8%). The values of items were statistically at 0.01 level.

The purpose of this study is to estimate a suitable traveling speed model based on using the traffic data collected by test-vehicle traveling method and the data on road geometric and operating characteristics. The conclusions of this study are as follows. In travel speed model(Q-V), regression model (V=9.635+0.0169L - 0.00045Q - 2.1926N, R²=0.76) the important independent variables are speed is closely related with distance, traffic volume and the number of traffic lane, form the result of speed-flow regression analysis, link travel speeds are influenced by link distance, traffic volume, and the number of lanes. As expectedly by the most significant factor influencing link travel speeds. The changing of traveling speed according to section distance is appeared large. According to the result of analysis of travel speed and traffic density model(Q-K), as according the that density increases the travel speed is decreases, on the other hand travel speed increases, the density decreases. The speed equation (u=68.72e^(-k/22.6)) is derived by form the Q-K relationships founded form the study, traffic volume increases as traffic speed increase up to the critical traffic density. If traffic volume decreases when traffic density is abduce the critical traffic density. Using Q-V equation estimated by regression analysis and Q-K equation estimated by density, Traffic value test was accomplished by computer program(TRANPLAN). There were difference between too test, however, the deviation was small. On case of using program, the application extent we considered, is between 25Km/h - 60Km/h. Traffic volumes obtained from TRANPLAN are governably 10% larger than traffic volume estimated form Q-K model. However the difference of the critical traffic density bow Q-K model and TRANPLAN, are relatively small. It is desirable to reduce traffic volume by 0.7∼9% over all, speed range when TRAPLAN is applied in Q-K relationship.

This study analyzed the characteristics of the operation of left turns at intersections of the streets in Taegu City. The points of the study were as follows: increase of traffic capacity, decrease of delay time, and to do so this study aims at seeking a way for the most appropriate signal cycle and an effective way to operate intersections. The following are the results: 1st The arterials of Taegu City have a high rate of left turns, and yet are not divided into specific functions, which impairs the efficient use of the functions. It is required that a study be made on the way of utilizing the left turn to the maximum of the operational functions of signalized intersections. 2nd As traffic volume and left turn ratio increase, it was revealed that the optimum signal cycle and delay increased, adoption of efficient lanes was analysed to be most effective at the intersection which have a great of traffic volume and a high or rate of left turns. 3rd On the independent intersection in Taegu city, when left turn is prohibited, it may give poor approaches, but according to analyses this will bring a phenomenal decrease in the optimum signal cycle and delay.
