  • The aim of this study was to estimate the shelf life of butter and cheese products, with shelf life being a guide used to determine the storage period of food before deterioration. Butter and cheese samples stored at $10^{\circ}C$ and $15^{\circ}C$ had a shelf life of 221 d, while those stored at $25^{\circ}C$ and $35^{\circ}C$ had a shelf life of 109 d. Quality changes, including total cell count, coliform counts, Listeria monocytogenes counts, acid value, moisture content, pH, acidity and overall sensory evaluation, were monitored. In order to pass the overall sensory evaluation, a quality score of 5 points on a 9-point scale was required. For other quality criteria, legal quality limits were established based on the "Process Criteria and Ingredient Standard of Livestock Products" by the Animal, Plant and Fisheries Quarantine and Inspection Agency (Republic of Korea). The nonlegal quality limit was estimated by regression analysis between non-quality criteria (y) and overall sensory evaluation (x). The shelf life was estimated based on the number of days that the product passed the quality limit of the quality criteria. The shelf life of samples stored at $10^{\circ}C$, $15^{\circ}C$, $25^{\circ}C$ and $35^{\circ}C$ was 21.94, 17.18, 6.10 and 0.58 mon, respectively, for butter and 10.81, 9.47, 4.64 and 0.20 mon, respectively, for cheese.

  • Airworthiness certification of military aircraft is a government's certification that it must have airworthiness and ability to demonstrate its requested function and performance. NATO released STANAG-4671 to establish the minimum airworthiness requirements for UAVs between 150kg and 20,000kg MTOW in 2009. Up to now, there are no clear airworthiness certification criteria and guideline for small UAV which is less than 150kg. STANAG-4671 is used for military UAV airworthiness certification in Korea as Other Airworthiness Certification Criteria. However, since STANAG-4671 requires the same Target Level of Safety without regard to MTOW, excessive Target Level of Safety or design requirements could be applied to relatively small-medium UAV. In this paper, classification and criteria of airworthiness certification for military UAV were investigated and a Target Level of Safety was analyzed based on MTOW using ground victim criteria.

  • EAP, which is operated on the frame of Risk Alarm 4-stage of National Risk Management Guideline, is a critical method in order to promptly respond to disasters. Korea Flood Control Office issues major and moderate flood alarm at each river station by respectively 50% and 70% of design flood discharge in terms of watermark or sea level, however, the criteria deciding major and moderate floods are vague for field managers to control the disaster situations. On the other hand, Japan and USA use river water level as a main criterion in order to classify the stage of flood disaster, which is higher design flood level than Korea. Thus, the authors analyzed domestic and oversea EAP guidelines and suggested improved criteria showing easy display method and raising the criteria of flood level for reflecting more effective action plans through testing a simulation training on the test-bed.

  • Establishment of safety net for the socially disadvantaged attracts large attention because of the recent crime increasing against vulnerable groups. For the successful establishment of social safety net, the test-bed for evaluation and realization of crime-related research results is required. However, previous R&D test-bed projects such as The Korean Land Specialization Program or U-Eco City project remains only to the stage of verification. Therefore, there are limitedness for realization of result technologies or sustainable operation & management of test-bed after projects finished. So, sustainable operation & management system and guideline of test-bed are necessary. Therefore, this study reviews the strengths and weaknesses of existing test-bed cases and intelligent security researches. After reviewing, the concept of a Intelligent Security Test-bed is established and appropriate test-bed selection criteria is also suggested. Based on objective criteria, selected test-bed can achieve sustainable management even after finishing the project and contribute the construction of standard model for citizen's safety.

  • This paper deals with the analysis of interior noise and low frequency noise characteristic for the Busan citizens to use public transport, Busan Metro Line 3. The interior noise evaluation index, articulation index(AI) is evaluated the lower value about average 22 % in a whole range, this is difficult to have a conversation. Also, noise criteria(NC) curve is partially evaluated as NC-65 below 2000 Hz, space type is evaluated as factories. Another of interior noise evaluation index, preferred speech interference level(PSIL) is evaluated the upper value about average 66 dB(A) in a whole range, this is evaluated to be interrupted. In the case of low frequency noise(20~200 Hz), the measurement of low frequency noise is assessed largely beyond noise criteria of ISO 226. The low frequency noise should be reduced because low frequency noise affects on psychological stress and displeasure although low frequency noise is not recognized by auditory sense. The low frequency noise criteria and guideline will be enacted from now on in Korea.

  • This paper reviews fundamentals of a pseudo-static seismic design/analysis method for soil-reinforced segmental retaining walls. A comparative study on NCMA and FHWA seismic design guidelines, which are one of the most well known design guidelines for mechanically stabilized earth walls, was also performed. The results demonstrate that there exist significant discrepancies in the results of external stability analysis despite the same calculation model used in the two guidelines, due primarily to different seismic coefficient selection criteria. It is also demonstrated that the internal stability calculation model for NCMA guideline tends to yield larger seismic reinforcement force in the shallower reinforcement layers, resulting in an increased number of reinforcement layers at the top of reinforced wall and increased reinforcement lengths to ensure adequate anchorage capacity. The internal stability calculation model adopted by FHWA guideline, however, leads to redistribution of dynamic force to the lower reinforcement layers and thus results n an opposite trend of NCMA guideline. Findings from this study clearly demonstrate a need for more in-depth studies to develop a generally acceptable design/analysis method.

  • The need for and components of a contemporary community pharmacy externship for pharmacy students have not been clearly identified in Korea. Mail survey was performed among 20 college of pharmacy deans and 800 community pharmacists to analyze the current status and develop a consensus regarding major focus area and criteria of community pharmacy externship to be implemented under the separation of dispensary from medical practice in year 2000. Mail survey yielded $80\%\;and\;23.5\%$ response rate for pharmacy school deans and community pharmacists, respectively. Of the 16 pharmacy schools that responded 14 said they have externship program in hospital pharmacy, and only 8 pharmacy schools responded of having externship program for community pharmacy. However, these community pharmacy programs lacked criteria and standard guideline for the externship. The results of survey revealed that community pharmacy externship program for students should be organized and directed toward developing expert knowledge and skills in pharmacy practice activities, clinical services, communications, pharmacy management, and professionalism. Pharmacy practice components should include competencies and skills in computer application, prescription processing, dispensing, pharmaceutical compounding, Narcotics Control Law application, maintenance and provision of drug information, and laws and regulations. Clinical service components should include the ability to identify patient's drug-related problems, provide long-term patient care and appreciate drug therapy services. Communication skills should be taught to effectively express his/her professional opinion, deduce the needs of others, utilize appropriate techniques and media to communicate ideas and conduct a patient interview and to obtain patient drug history. Pharmacy management skills should be taught to be efficient in medical insurance and drug control process. It was found that professionalism, morality, pharmacy practice experience, ability to provide clinical services, collect and provide drug information and regality are important criteria of preceptors. Externship sites should possess the ability to stock various drugs, access and provide diverse pharmacy services and should have private patient counseling area. Most pharmacists agreed that top 200 drugs' generic and brand name, indications, dosage, side effects, and contraindication should be instructed during the externship. It was also found that student and preceptor should be evaluated for their performances during the externship. This information will be incorporated into teaming objectives for students and to develop Academic Extemship Program Guidelines.

  • Objectives : To address most probable and suitable method for designing clinical trial intervening Traditional Korean Herbal Medicine on hwa-byung. Study Design : A systematic review of research studies of complementary and/or alternative medical(CAM) treatment of depression, and of domestic clinical trials of Traditional Korean Medicine, and of Chinese clinical trials of Traditional Chinese Medicine. Methods : Randomized, controlled trials(RCTs) of treatment of depression intervening herbal medicine were searched through MEDLINE, Cochrane Library, and CNKI databases. Also, domestic RCTs intervening Traditional Korean Herbal Medicine were searched through Korean Traditional Knowledge Portal and Korean studies Information Service System(KISS). Studies were evaluated using Iadad scale and self-designed tool for this study. Results : Thirty four RCT studies( 10 from MEDLINE, 16 from CNKI, 8 domestic studies) of herbal medicine met inclusion criteria. Mean Jadad score of studies published in English was 2.8${\pm}$0.79, in Chinese 1.94${\pm}$0.77, and in Korean 2.75${\pm}$0.71. Twenty one percent of studies included pattern differentiation in their inclusion criteria. Twenty nine percent of studies used combined treatment of herbal and conventional medicine. Among studies on depression, 9% included Complementary Medical assessing tools. Conclusions : There is shortage of domestic clinical trial involving herbal medicine. In China, studies tend to focus on investigating effect of Combined treatment of herbal and conventional medicine on depression. Clinical trial(s) of hwa-byung should provide good internal validity by describing methodology for randomization, double-blinding, and attrition. Also, specific guideline for clinical trial, including Traditional Korean Medical aspects across inclusion criteria, and assessing tools is needed.
