The intent of this study is to propose future planning guidelines and directions of the mixed-use buildings in the residential land development district in country-side cities, based on the concept that the neighborhood facilities are to be strategically laid out in a convenient location and planned in a proper manner for a healthy, safe, friendly and new neighborhood environment. For this purpose, seventeen mixed-use buildings which had been built in Shin-Eum housing development district in Gimcheon from 1995 until 2004 were chosen and investigated in terms of architectural characteristics in that process with surveying and analyzing those. The scope of investigation on case studies was that site size would be below 400 square meters, total area below 1500 square meters, and the number of stories below five stories high on the ground. Method of investigation on those was through field investigation, field photographs, recordings and drawings on those. Investigative contents have been divided and analyzed into the quantitative and qualitative factors in urban and architectural dimension. From results of quantitative investigations, five planning guidelines or directions could be obtained. From results of qualitative investigations, five planning guidelines or directions could be obtained. The criteria will be applied to new architectural developments of the neighborhood facilities linked with the small shops.

PURPOSE: This study was to investigate the effectiveness of TENS on balance in stroke patients by analyzing some components such as foot pressure, limit of stability and velocity sway after providing somatosensroy input using TENS. METHODS: Twenty five subjects participated and were randomly divided into two groups, TENS group (n=13) and control group (n=12) by the computer program. Interventions were given to subjects 5 days a week for four weeks. TENS group were treated with TENS for 60 minutes in addition to the conventional therapy which included 30-minute exercise and rehabilitation ergometer training for 15 minutes. Control group performed only conventional therapy. TENS was applied on the skin of soleus, tibialis anterior, tensor fascia latae and vastus medialis in affected side. Foot pressure, limit of stability and velocity sway for balance test were measured using Biorescue. RESULTS: TENS group was significantly increased limit of stability and foot pressure in affected side more than control group. And in eye closed condition, TENS group was significantly decreased velocity sway more than control group. CONCLUSION: The application of TENS is effective to improve the somatosensory input of affected side and to increase the motor function and balance ability.

PURPOSES : The purpose of this study is to compare the lane curing time of natural drying and a lane drying device when painting lines on a highway. METHODS : The painting process was carried out in July 2015 and September 2015, respectively, for the Gimcheon IC - Gimcheon JC. After the painting, measurements were obtained three times at six measurement points located at 20 m intervals on the shoulder line and the dividing line. The curing time was measured for natural drying and drying using a lane drying device, and compared for different pavement types (asphalt, concrete) and paint types (waterborne paint, methyl methacrylate paint). RESULTS : The results of the lane curing time comparison on the highway are as follows. The combination of asphalt and methyl methacrylate paint cured more rapidly during both the natural drying and drying using the lane drying device. Finally, it was cured at least 32.2% and 40.7% faster when using a drying device than in natural drying. CONCLUSIONS : The comparison of lane curing time of the highway showed that the combination of asphalt and methyl methacrylate paint cured more rapidly when using both natural drying and a lane drying device.

PURPOSE: This study investigated the efficacy of interferential current (IFC) treatment on the improvement of pain, disability, and balance in patients with chronic nonspecific low back pain. METHODS: A double-blind randomized clinical trial was conducted with 40 patients with chronic nonspecific low back pain. The patients were randomly allocated into two groups: the IFC treatment group (n = 20) and the placebo treatment group (n = 20). The IFC group received 30 minutes of IFC treatment on the lumbar region, while the placebo group received IFC treatment without real electrical stimulation. The intervention was administered five days a week for two weeks. RESULTS: The primary outcomes of resting pain and pain during functional movement were measured by a visual analogue scale. The secondary measurements included the Oswestry disability index (ODI) for low back pain and postural sway. The measurements were performed before and after the two-week intervention period. Compared to the placebo treatment group, the IFC treatment group showed significantly greater improvement in pain during anterior trunk flexion in the standing position (p = .029), ODI (p = .039), and postural sway when subjects stood with their eyes closed (p = .010) at the end of the intervention. CONCLUSION: Our findings show that IFC treatment can improve pain, disability, and postural sway, thus, highlighting the benefits of somatosensory stimulation from IFC.

The closely related species Actinobacillus actinomycetemcomitans, Hemophilus aphrophilus and Hemophilus paraphrophilus are common findings in oral microbiota. The aims of this study were to compare the distribution of three species in healthy subjects and periodontitis patients using PCR for 16s rRNA gene. The DNA was extracted from the subgingival plaque and saliva in 122 subjects for restriction enzyme analysis with Hinf I and Hha I. In case of periodontally healthy person, A. actinomycetemcomitans was predominant than H. paraphrophilus in saliva sample, but H. paraphrophilus was predominant than A. actinomycetemcomitans in subgingival plaque sample. On the contrary, in case of periodontitis patients, H. paraphrophilus was predominant than A. actinomycetemcomitans in saliva sample, but A. actinomycetemcomitans was predominant than H. paraphrophilus in subgingival plaque sample. In addition, the fact was confirmed that the distribution of A. actinomycetemcomitns of women periodontitis patients was somewhat higher than men periodontitis patients in saliva and subgingival plaque samples. We convinced that the PCR method for 16s rRNA gene was important for screening and monitoring of periodontal disease.

Objectives: The purpose of the study was to investigate the cumulative dental caries rate of pit and fissure sealant in community public health program from 2005 to 2008 follow-up. Methods: The subjects were 4,768 students of 34 elementary schools in Gimcheon. The survey included direct oral examination and cumulative retention rate of pit and fissure sealant from 2005 to 2008. Data were analyzed using PASW statistical package version 18.0 and the level of significance was set at p<0.05. Results: The cumulative retention rate of sealant was 18%, 25%, and 33% after 1 year, 2 years, and 3 years, respectively. In addition, the cumulative retention rate of lower teeth was higher than that of upper teeth. Cumulative dental caries rate increased in sealed group and no sealed group. The cumulative dental caries rate decreased owing to tooth brushing frequency in sealed group and no sealed group. Conclusions: Regular and timely tooth brushing can maintain good oral health condition after tooth sealing. The school based oral health education can prevent loss of sealant and secondary caries.
