This study was performed to propose a development guide for the periphery of local industrial park in the region of Hongseng-gun located at the mid-west of Chungnam province., which is a representative agrarian society, has been approached to a super-aged society where the region shows a continuous decrease in population, and the composition ratio of old ages is about 17.1%. Also, the region is a period of a low ebb due to the traditional agriculture based industrial structure in producing mainly simple productions. Many local governments in agrarian and fishing regions have been efforted for luring some businesses in their regions by constructing industrial complex competitively in order to solve such structural problems in such local regions. However, in some cases, these efforts cause certain destructions in the local original natural environment due to such development of industrial complex and the decrease in the settlement environment of residents. The objective of this study is to establish a local development plan for building the sustainable and comfortable settlement environments based on the settlement of the residents and the labors in such industrial complex by preventing sprawl developments in the construction of general industrial complex. This study was processed as following procedures. First, this study drew the trend in the change of the local society of H-gun through collecting literatures and analyzing it. Second, this study proposed a proper level of settlement environments required to the development of surroundings in such industrial complex based on the survey of the consciousness of residents using a statistical method. Finally, this study proposed a development guide for the surroundings based on the proposed level of settlement environments.

In this paper, a smart home service robot McBot II is newly developed in much more practical and intelligent system than McBot I which we had developed a few years ago. Thus far, vacuum-cleaners have lightened the burden of household chores but the operational labor that vacuum-cleaners entail has been very severe. Recently, a cleaning robot was commercialized to solve but it also was not successful because it still had the problem of mess-cleanup, which pertained to the clean-up of large trash and the arrangement of newspapers, clothes, etc. Hence, we develop a new home mess-cleanup robot McBot II to completely overcome this problem on real environments. The mechanical design and the basic control of McBot II, which performs mess-cleanup function etc. in house, is actually focused in this paper. McBot II is mechanically modeled in the same method that the human works in door by using the waist and the hands. The big-ranged vertical lift and the shoulder joints to be able to forward move are mechanically designed for the operating function as the human's waist when the robot works. The mobility of McBot II is designed in the holonomic mobile robot for the collision avoidance of obstacle and the high speed navigation on the small area in door. Finally, good performance of McBot II, which has been optimally desinged, is confirmed through the experimental results for the control of the robotic body, mobility, arms and hands in this paper.

The purpose of this study was to know the characteristics of DDK performance between CV(e.g. 'pa') and VV(e.g., 'ai') syllables in typically developing children aged 4 to 6 years old. 12 TD children performed DDK with CV structure(/pʰə/, /tʰə/, /kʰə/, /pʰətʰə/, /tʰəkʰə?/, /pʰətʰəkʰə/) and with VV structure(/ai/, /ɔi/, /ɑɔi/). Spoken syllables were counted in one second, and all spoken DDK were measured by PC-quirer. The results showed that all spoken DDK became faster as the age of children were increased. This trend was also appeared in both CV and VV syllables repetition. In addition, there was no differences in DDK rate with CV and VV syllables. The frequency of articulatory error during DDK performance was very high in the age of 3, and there was no pattern in the frequency of articulatory error according to the developmental age.

This present study is designed to analyze the mortality and potential years of life lost (PYLL) by malignant neoplasm of lung between OECD countries and Korea before and after the year 2000. We used the methods of Wilcoxon Singed Ranks Test between korean and other 30 OECD countries between 1993-1999 and 2000-2006 year using 2009 OECD Health data(2010) of 30 contries. At the results, the mortality of lung cancer in male korean was significantly increased after 2000 year whereas those in other 23 countries decreased. The mortalities in female were increased in 20 countries including Korea. PYLL in male and female korean were significantly decreased and male PYLL in other 26 countries was decreased, but female PYLL in other countries showed various patterns; increase in 12 countries and decrease in 3 countries. Therefore, the present study elucidated that the lung cancer-induced PYLL in the comparison between korean and OECD countries can be more important parameter.

This study investigated the quality characteristics of the muffins with garlic paste. Four different paste concentration levels of 0, 40, 80 and 120g were added to 200g flour to make the muffin. In terms of color, the lightness and yellowness of the muffin increased and redness decreased with increasing amounts of garlic paste. Among the textural characteristics hardness, springness, cohesiveness, gumminess and chewiness were increased according to the addition level of garlic paste. However, there were no significant differences in hardness and springness of the muffin. For the sensory evaluation, appearance, flavor, taste and texture of the muffin was not significantly different than the control group. The appearance, taste, texture and overall acceptability were excellent in the group with the addition of 40g garlic paste. From the results of this study, the muffin with 40g garlic paste added content was shown to have the best quality.

To understand size fractioned chlorophyll a and material cycle characteristics in Jeju marine ranching area (JMRA), 4 times of survey were conducted from April to November 2008. Picoplankton on the surface in JMRA was on average, $0.30{\mu}g/L$(annual mean(M):17.3%) in the $0.03{\sim}0.84{\mu}g/L$ range, accounting for 17.3%. Nannoplankton and picoplankton was on average, $1.35{\mu}g/L$(M:78.0%) in the $0.22{\sim}3.93{\mu}g/L$ range, and $1.73{\mu}g/L$(M:4.7%) in the nd ~ 0.24 range, respectively. The 10m layer was similar to the surface. The measured values changed according to the measurement times but the nanoplankton composition ratio was higher throughout the year. In addition, the size fractioned chlorophyll a distribution in JMRA was similar to that of tropical sea area affected by the Monsoon rather than South Korean offshore coast geographically adjacent to the East China Sea and Japan coastal waters affected by the Kuroshio/Tsushima warm currents. That is, the material cycle of JMRA consists of a microbial food web rather than traditional food chain at a lower trophic levels. Primary production is deemed to have a higher possibility of being adjusted by top-down dynamics, such as micro-zooplankton grazing pressure rather than nutrients supply.

The purpose of this study was to examine the effect of transcutaneous electrical nerve stimulation (TENS) according to frequency and intensity on postural sway distance and velocity. TENS was applied to posterior aspect of the dominant leg with postural sway during one leg stance. Twenty-four healthy participants were measured while standing on a force platform with 5 different stimulation dosages of no TENS, high frequency and high intensity, high frequency and low intensity, low frequency and high intensity, low frequency and low intensity applied in 30 seconds. The five different dosages were performed with vision in random order. The results indicated that TENS dosage in the high frequency and low intensity had a significant decrease in postural sway(p<.05). From these results, we concluded that TENS delivered a high frequency and low intensity enhanced the postural sway in healthy adults. We expect that the postural sway of patients with decreased balance will reduce by application of TENS.

The aim of this study is to suggest a detection method of water surface location and its evaluation results of application for same vertical position in two successive images with time interval including both staff gauge and water surface. A specific rectangular inspection area is defined from the top of watermark and then the correlation coefficients for the inspection area of the same position of two images with short time interval is calculated. Accordingly, it is possible to identify differences between changing area and fixed area of pixel density by the water flow. The photographs taken in the laboratory were analyzed in order to validate the proposed technique. As the result of the experiment, it is identified that characteristic of correlation coefficients depends on the size of the inspection area. In the case that the inspection area is within the entire width of the watermark, water surface characteristic according to correlation coefficients is clearly noticeable. Thus, it is identified that the proposed technique can be utilized to search water surfaces. Besides, using corelation analysis of two images with time interval, it is identified that error range between 10 and 42cm was reduced in the level of 2.6cm or less in the contaminated photo of existing image stage gauge. Therefore, it is expected that the suggested method can be utilized to enhance image stage gauge performance improving the previous water surface detection method.
