Purpose: Hypertension has been a major cause of death in Korea since the 1970s, and has resulted in being a significant economic burden to the finances of national health care. The Ministry of Health and Welfare made several efforts. but hypertension control programs in Korea are still non standardized and ineffective. We wanted to investigate the current hypertension control program in public health centers systematically and suggest the direction for future programs. Method: The design of this study is a cross sectional investigation. From September to October in 2002, we sent a set of questionnaires to all PHCs, and 179 centers responded (response rate = 74.0%). The instrument was developed based on components of National health systems. Results: 1) Resources: The department responsible for hypertension control programs is the Department of Health Promotion. Health Education Center, Community Health Center, Citizen's Health Center, etc. The chief personnel of those departments are nurses. but 27.4% of PHCs have no full time nurse for hypertension management programs. PHCs had a lot of teaching materials (nine types per a PHC) and most of the recommended contents were included. But, periodical evaluation and revision were not being made, 2) Management: Nurses' (13.03 9.46 in 23 score) actions for hypertension control were not qualitative, but regular training and evaluation were seldom carried out. Need assessment (25.9%) and evaluation (about 10-20%) for the hypertension control program were indicated as low. 3) Programs: Programs focused on individuals rather than community or public, and 2nd prevention rather than 1st, 3rd prevention. Conclusion: The Ministry of Health and Welfare has to construct the infrastructure for hypertension control programs. Related scholars and committees should develop and declare standardized manuals for hypertension control and the management system, as well.

An investigation was carried out to assess the carcass characteristics and meat quality aspects of immunocastrated male pigs of medium genetic potential for lean meat deposition in carcass (53 to 55%). When the crossbred Large White x Landrace pigs (n = 45) were 70 days old, they were distributed in a totally randomized design in three treatments (castrated males, females and immunocastrated males) with three replicates of five animals. The pigs were slaughtered when they were 140 days old. Carcass temperature and pH were recorded twice, at 45 min and 24 h after slaughter. The carcasses were evaluated for hot and cold carcass yield, commercial cuts yield, length and depth, back fat thickness, loin eye area and lean meat percentage. The Longissimus dorsi muscle was extracted for analysis of color ($L^*$, $a^*$, $b^*$), exudate loss, cooking loss and centesimal and sensorial analysis of the meat. There were no significant differences for the evaluated parameters between castrated males, immunocastrated males and females, except for backfat thickness between the 7th and 8th thoracic vertebra and the point P2 (lower for immunocastrated males) and carcass temperature at 45 min post slaughter (higher in immunocastrated males), however, this did not interfer with the rate of pH decrease post mortem and the meat quality. The results from this research did not indicate a benefit of immunocastration on carcass characteristics of pigs of medium genetic potential for lean meat deposition in carcass, when compared to surgical castration.

Due to desire for more variation from male consumers within the men's fashion market in Korea, there has been an ongoing development of departmentalization of fashion styles. The Generation-X man, in particular, is the most active member of our current day society, and will be the principal agent in the senior market from here on forth. Thus, this study categorized their preferred fashion styles, and will seek to analyze the behaviors related to the pursuit of clothing of the Generation-X man. The qualitative investigations of the Q-method as well as the quantitative investigation of the SPSS 12.0 were used in conjunction as the method of study. Additionally, images and types resulting from the preceding first-year study entitled "The Type and Characteristics of the Modern Men's Fashion Images" were utilized as part of the surveys. As a result of the Q-method, which was used to derive the preferred fashion styles of the Generation-X man, they were classified into three categories: the classic suit preferring 'conservative class type', the polished, comfortable style preferring 'modern sophisticated type', and the adventure and variety seeking 'uninhibited individualistic style'. After analyzing the factors which influence clothing preference behaviors of these men, a total of seven causes were drawn from the results, including: conservative indifference to fashion, others conscious pursuit of fashion, the aim to show off brand name products, high involvement in the aspect of design, pursuit of TPO, pursuit of self-image, and conformity to fashion. The elements that revealed differences in the behaviors in pursuing clothing within the preferred fashion style types of the Generation-X man included the conservative indifference to fashion, and others conscious pursuit of fashion, which therefore shows that rather than enjoying the fashion lifestyle, these men possess a more conservative disposition instead.

The plume infrared signature effects at various flight conditions of aircraft were investigated for the purpose of reducing infrared signature level. The nozzle of a virtual subsonic unmanned combat aerial vehicle was designed through a performance analysis. Nozzle and associated plume flowfields were first analyzed using a density-based CFD code and plume IR signature was then calculated on the basis of the narrow-band model. Finally, qualitative information for the plume infrared signature characteristics was obtained through the analysis of the IR signature effects at various flight conditions.

Recently, systems biology has been increasingly applied to gain insights into the complexity of living organisms. Many inaccessible biological information and hidden evidences fur example flux distribution of the metabolites are simply revealed by investigation of artificial cell behaviors. Most bio-models are models of single cell organisms that cannot handle the multi-cellular organisms like plants. Herein, a structured and multi-cellular model of potato was developed to comprehend the root starch biosynthesis. On the basis of simplest plant cell biology, a potato structured model on the platform of Berkley Madonna was divided into three parts: photosynthetic (leaf), non-photosynthetic (tuber) and transportation (phloem) cells. The model of starch biosynthesis begins with the fixation of CO$_2$ from atmosphere to the Calvin cycle. Passing through a series of reactions, triose phosphate from Calvin cycle is converted to sucrose which is transported to sink cells and is eventually formed the amylose and amylopectin (starch constituents). After validating the model with data from a number of literatures, the results show that the structured model is a good representative of the studied system. The result of triose phosphate (DHAP and GAP) elevation due to lessening the aldolase activity is an illustration of the validation. Furthermore, the representative model was used to gain more understanding of starch production process such as the effect of CO$_2$ uptake on qualitative and quantitative aspects of starch biosynthesis.

In this paper, infrared thermography measurement technique has been used to develop standard measurement technique for nondestructive testing of composite materials which is widely used in aerospace industries. To increase the defect detection rate, the related experiment used the lock-in IR-thermographiy method. Therefore it is of considerable interest in the field of non-destructive testing for fast discontinuity detection by using ultrasonic lock-in infrared thermography. The result also shows that as the investigation period of light source is lengthened according to the thickness of specimen, the possibility of detecting defects gets higher as well. However, the reason why the result values were not favorable when less than 50 mHz of light source was provided is because it was difficult to detect defects as the defect parts became a state of thermal equilibrium in general when thermal diffusivity affects the entire materials.

The qualitative distribution of a fractured aquifer was characterized by electrical resistivity surveying as a part of basic groundwater investigation in Jangseong. The results were then used to choose sites for observation wells. The locations and distributions of permeable discontinuities were studied by analyses of temperature logs, a borehole image-processing system (BIPS), and hydraulic pressure testing using a double packer. The pressure test showed that the size of the discontinuities correlated with the Lugeon value and the results of the temperature log. The results show that temperature measurement is an effective method to identify permeable discontinuities, with the temperature difference correlating with the size of the aperture of the discontinuity.

Ground CS-891 (N-[1-(4-methoxyphenyl)-1-methylethyl]-3-oxo-4-aza-5a-androst-1-ene-$17{\beta}$-carboxamide) of poorly water soluble drug was obtained using a Heiko Seisakusho model TI-100 vibration mill, and samples with different crystallinity were prepared at mixture ratios of 10:0, 7:3, 5:5, 3:7 and 0:10 (intact;ground CS-891). Physicochemical characterizations were obtained using qualitative and quantitative X-ray diffractometry, different scanning calorimetry (DSC), scanning electron microscopy (SEM), Quantasorb surface area analyzer, and controlled atmosphere microbalance. With increase of amorphous CS-891 in mixture ratios, the intensities of X-ray diffraction peaks of crystalline CS-891 were decreased, whereas surface area, water absorption, and exothermic peaks in DSC were increased. The apparent solubility of ground CS-891 was $4.4\;{\mu}g/ml$ and the solubility of intact CS-891 was $3.1\;{\mu}g/ml$ at $37{\pm}1^{\circ}C$. The apparent precipitation rates of CS-891 in a supersaturated solution during the solubility test were increased with an increase of amorphous CS-891, and a crystalline form of CS-891 transformed from amorphous CS-891 after the solubility test was found by X-ray diffraction analysis, DSC and SEM. The dissolution profiles of CS-891 with different crystallinity at $37{\pm}1^{\circ}C$ by the USP paddle method were investigated, and the apparent dissolution rate constant of ground CS-891 was about 5.9-fold higher than that of intact CS-891. A linear relationships between the crystallinity of CS-891 and the apparent dissolution rate constant (r>0.96) were obtained.
