What is a role of the studies on spatial planning of Korean peninsular and its cities in the process of cooperation between and unification of South and North Korea? Where should the basic perspectives be oriented for the process? Can a comprehensive plan of North Korea have practical implications although South-North cooperation does not get into its stride? If it can, which contents should the plan cover? This study aims to contemplate these issues and to suggest a preliminary land development approach of North Korea, which would contribute academic and practical debates on the issues, at this juncture of the cascade of studies on spatial planning in North Korea. It assume South-North relation would evolve from 'reconciliation and cooperation' and 'confederation' into 'unification' of South and North Korea which is based on the official plan of South Korea. We suggest, as the basic perspectives of development approach, cooperation(or co-evolution), future-oriented sustainability, and parallel development of industry and physical infrastructure. The development potential of North Korea is explained by detail fields and sub-regions, which is used to analyse SWOT and to subsequently extract the basic directions(vision and strategies) of North Korea development. These directions are followed by the spatial structure plan to improve North Korea using the potential of the regions. Based on the plan, the development directions of detail fields are suggested.

In this study, lactic acid bacteria with high angiotensin converting enzyme inhibitor activity were isolated from Korean fermented food, such as kimchi and salted seafood. The strain HLJ59, isolated from salted shrimp showed the highest angiotensin converting enzyme inhibitor activity in DeMan Rogosa Sharpe broth. Optimum growth temperature of Lactobacillus brevis HLJ59 was at $34^{\circ}C$. Acid treatment at pH 3.0 for 1.5 h decreased cell viability from $9.9{\times}10^8$ CFU/ml to $3.11{\times}10^4$ CFU/ml. The bile extract concentration of 0.3%, 0.5%, and 1.0% in MRS broth did not inhibit the growth of HLJ59. Isolated strain HLJ59 showed more sensibility to amikacin, gentamycin, neomycin, streptomycin, kanamycin, cefmetazole, cephalothin, ampicillin, ticarcillin, sulbactam+ampicillin, amoxicillin+clavulanic acid (AMC), tetracycline, and sulfamethoxazole+trime thoprim (SXT) as compare to other 7 different antibiotics. However, it showed more resistance to cefoxatin, ceftnaxone, penicillin, ciprofloxacin, nalidixic acid, lincomycin, and chloramphenicol.

The purpose of the study was to analyze the effects of both young children's gender and temperament and their teachers' teaching efficacy and teacher-child interactions on peer play interactions. For this purpose, the data from the 2012 Panel Study on Korean Children were analyzed using analyses of variances and correlation co-efficiencies. In addition, analyses of hierarchical regression, with young children's temperament and teacher-related factors (teaching efficacy and teacher-child interactions) as the independent variables and three sub-factors of peer play interactions (play interaction, play disruption, play disconnection) as the dependent variables, were conducted. The results showed that young children's temperament, teacher efficacy, teacher-child interactions, and peer play interactions differed by gender and significantly correlated. Young children's temperament and teacher-child interactions significantly affected young children's peer play interactions, and the effect of teacher-child interactions was larger than the effect of temperament by 2~2.5 times. The results proved the importance of early childhood teachers' roles in the development of young children's peer interactions with consideration of differences based on children's gender and temperament. With the results given, implications and suggestions for further research were discussed.

Although most cases of tension-type headache(TTH) are myogenic headache, in some cases, arthralgia appears, such as the disorder of the temporamandibular joint. This study is designed to compare the clinical patterns of arthralgia to those of myalgia, when both symptoms are co-existing. Among 167 patients who visit our clinic during a certain period, whose chief complaint was TTH, 18 patients were the arthralgia group, 50 patients were the myalgia group, and 99 patients who have both arthralgia and myalgia were the arthromyalgia group. Three groups were asked to answer the questionnaires about their age, gender, and oral parafunction such as bruxism or clenching. Then we gathered statistics on the data from the accomplished questionnaires. 1. There was statistical significance in age among the three groups(p=0.02). 2. There was no statistical significance in sex and oral parafunction among the three groups. 3. There was statistical significance the myalgia group was older than the arthromyalgia group(p<0.03). The results of the study show that as patients become older, TTH with myalgia happens more frequently than TTH with arthralgia and myalgia does.

Efficiency of dredging work depends on the types of equipment used, the sediments encountered, whether the work to be performed is new or for maintenance, pre and/or post hydrographic surveying and so forth. Among those, surveying accuracy which is directly determined by the control of the dredge's position and depth surveying accuracy being surveyed at the dredging point are important factors. The purpose of this study is to develop an integrated process management system for pump dredge. The system is composed of 4 sub-systems such as LADGPS for dredge positioning dredging point determination, tidal gauge and angular depth sensor for depth determination, and GIS and ENC process management. The process management system for pump dredge developed was installed on the pump dredge "EUNJIN PD-2" but is now producing work data for comparison with performance of the existing dredge. The data retrieved from the pump dredge process management system up to now shows similar result from the grab dredge management system which was developed previously. It is easy to operate, achieves good accuracy with only 45cm unevenness, reduces working perioa by 20 percint,. More precise evaluation of the system comes later after the dredging work is completed.completed.

This study was performed to investigate the effects of puffed-red ginseng (PRG) powder and drink on blood glucose level and serum lipid profile in streptozotocin (STZ)-induced diabetic rats. For the experimental design, STZ-induced diabetic rats were fed PRG powder-supplemented diets (0.3%, 0.6%) and diluted drinks (0.14%, 0.28%) for 6 weeks. Concentrations of blood glucose during the experimental period decreased to 18.3 mg/dL in the 0.6% PRG diet group and 15.1 mg/dL in the 0.14% PRG drink group. Average reduction rate of blood glucose in the last week compared to reference blood glucose concentration decreased by 19.2% (A group), 37.4% (B group), 18.7% (C group), and 17.3% (D group) in the PRG treatment groups, respectively. These results indicate that PRG affects blood glucose via ginseng saponins administered in diet or drinking water, thereby suggesting that PRG has the ability to prevent increasing blood glucose in mild-induced diabetic rats.

Pelvic floor muscle is the main sub-system that maintains urinary continence. The weakness of pelvic floor muscles causes the stress urinary incontinence, and therefore the degree of functioning of pelvic floor muscles could be used as an index to assess the degree of stress urinary incontinence. In this study, the quantitative diagnosis algorithm was proposed to estimate the degree of stress urinary incontinence (SUI) by measuring the contraction pressure of pelvic floor muscle. For these reason, the contraction pressure measurement system from pelvic floor muscle was developed, and the measuring protocol was suggested to analysis the obtained data. As the results of clinical test, the proposed diagnosis algorithm shows the 80% of accuracy, and 20% of false positive diagnosis. On the other hand, false negative results were not confirmed. Consequentially, we thought that the proposed urinary incontinence diagnosis algorithm can quantitatively diagnose the progression of the stress urinary incontinence and it can be used for the development of the incontinence diagnosis system.

It was attempted to find a method to prevent greening of crushed garlic. The storage conditions and heat treatments before crushing were tested for the prevention of greening in crushed garlic. 'Namhae' garlic (sub-tropical type), 'Seosan' and 'Danyang' garlic (traditional) type for cool area) were stored in room temperature(20${\pm}5^{\circ}C$, low temperature(0$^{\circ}C$), and CA(O$_2\;3%,\;CO_2$ 5%) storage for five months, and their samples were crushed. The crushed garlic had no significant differences in greening according to the cultivars. Greening did not occur for the crushed garlic from bulbs stored either in room temperature or CA storage. Greening was the unique symptom observed in crushed garlic from bulbs stored in low temperature. For the prevention of greening, heat treatment was conducted at 40, 35 and 30$^{\circ}C$ prior to make the crushed garlic from bulbs which were stored in low temperature. The effective duration of heat treatment before crushing was 7 days at 30$^{\circ}C$, 3 days at 35$^{\circ}C$, and 1 days at 40$^{\circ}C$ Greening was most effectively prevented in 1 day at 40$^{\circ}C$ treatment. During the heat treatments, changes in enzymatic pyruvic acid content and sprouting rate were slightly observed in garlic bulbs treated at 40$^{\circ}C$ for 1 day.

Purpose: These studies were undertaken to evaluate the anti-oxidative and neuroprotective effects of Gamisoyo-san(GMSYS). Materials and Methods: We studied the antioxidant effects of GMSYS by assessing the DPPH free radical and the ABTS radical cation inhibition activities, the total polyphenolic contents(TPC). To evaluate the effects of GMSYS in the human neuroblastoma cells, we measured the cell viabilities in SH-SY5Y cells treated with GMSYS. Then we observed the protective effects of GMSYS against 6-OHDA induced neurotoxicity in SH-SY5Y cells. To confirm the neuroprotective effects of GMSYS in the primary culture of mesencephalic dopaminergic cells, we counted the TH-immunopositive cells and measured the NO and TNF-$\alpha$ after the treatment of GMSYS and 6-OHDA. Results: The DPPH free radical and the ABTS radical cation inhibition activities were increased in a dose dependent manner and the IC50 were $133.60{\mu}g/m{\ell}$ and $106.20{\mu}g/m{\ell}$, respectively. The TPC was 0.78%. There were no differences between the various concentrations of GMSYS and the control in the cell viability of SH-SY5Y cells. The neuroprotective effects of GMSYS were shown in the co-treatment group at the low concentrations of $25{\mu}g/m{\ell}$ and the post-treatment group at all concentrations. After the treatment of GMSYS and 6-OHDA in the primary culture of dopaminergic cells, the TH-immunopositive cells were significantly increased in $0.2{\mu}g/m{\ell}$ of GMSYS than the 6-OHDA group. The NO and TNF-$\alpha$ were significantly decreased in $0.2{\mu}g/m{\ell}$ of GMSYS than the 6-OHDA group. Conclusions: This study shows that GMSYS has the antioxidant and neuroprotective effects, especially in the mesencephalic dopaminergic cells. We suggest that GMSYS could be useful for the treatment of postmenopausal depression related with the degeneration of dopamine neuron.

Purpose: The purpose was to assess the usefulness of midazolam in patients undergoing minor oral surgery under conscious sedation. Materials and methods: Bispectral index was examined in 20 patients receiving oral minor surgery with conscious sedation supplemented with local anesthesia. All patients included were ASA I and had no contraindications to the study medications. The patients were escorted to the day surgery operation room where, before the commencement of the sedation and surgical procedures, routine monitoring was applied, including the noninvasive monitoring of arterial blood pressure, arterial oxygen saturation, and 3-lead electrocardiogram (Electrocardiogram). Bispectral index electrodes were applied on the frontotemporal region after cleansing the skin with alcohol. Bispectral index was calculated with the Electrocardiogram monitor (A-2000; Aspect Co.). Midazolam was then titrated (initially 3mg wait 2min and 2mg). Vital sign and Bispectral index checked every 5 minute until the end of the procedure. The results were then compared. Results: The Bispectral index index values throughout the sedation study period alter many level. The index was dropped at 5 minutes after administration, but raised at injection and odontomy procedure. During the operation, mean Bispectral index index was higher than conscious sedation index range($60{\sim}80$). The amnesic effect was shown 17 cases out of 20 cases(85%). Conclusion: Conscious sedation technique using midazolma is a safe and effective method of controlling behavior in oral and maxillofacial surgery.
