Purpose: This study was done using meta-analysis to examine 58 studies from studies published in the past eight years (2000 to 2007) that included variables related to adolescents' suicidal ideation. Methods: The materials for this study were based on 32 variables which were selected from masters' thesis, doctoral dissertation and articles from Journals of the Korean Academy of Nursing. Results: The classification consisted of 5 variables groups and 32 variables. In terms of effect size on risk, variables which were significant included psychological variables (0.668), socio-cultural variables (0.511), family environmental variables (0.405), school environmental variables (0.221), and personal characteristics variables (0.147). In terms of effect size on protection, variables which were significant included personal characteristics variables (-1.107), psychological variables (-0.526), family environmental variables (-0.264), and school environmental variables (-0.155). In terms of effect size on risk variables, psychological variables (0.668) were highest. In terms of effect size on protective variables, the variable of personal characteristic (-1.107) was the highest. Conclusion: While the results indicate possible risk and protective variables for suicidal ideation, but prediction is still difficult. Further study to compare adolescents with similar variables but no suicidal ideation and those with suicidal ideation is necessary.

Purpose: This study was to estimate the effectiveness of an intervention program using the trans-theoretical model on the stages of change, the process of change, decisional balance, self-efficacy, the levels of medication adherence, and blood pressure difference. Methods: A similar experiment was conducted using a nonequivalent control group pre- and post-test design. The study subjects were 108 hypertensive patients. The program was administered to the experimental group while educational materials were given to the control group. Descriptive analysis, 2-test, t-test, and repeated measures ANOVA were used with SPSS 17.0 to analyze collected data. Results: After treatment with this program, the experimental group showed stage of change ($x^2=52.917$, p<.001), cognitive (F=13,528, p<.001), behavioral process of change (F=10.808, p<.001), benefits (F=5.569, p=.012), loss of medication adherence (F=15.661, p<.001), self-efficacy (F=5.407, p=.011), levels of medication adherence (F=51.442, p<.001). Conclusion: There was a significant improvement in the experimental group who participated in the TTM medication adherence intervention program. Given that this intervention program motivated and stimulated hypertensive patients to adhere to the prescribed medications, the TTM medication adherence intervention program is expected to be an effective and practical intervention method for health improvement.

Materials retaining electrolyte of a phosphoric acid fuel cell (PAFC) have been prepared with SiC powder to SiC whisker mixing ratios of 1:1, 1:2, 1:3, 1:4, 0:1 by a tape casting method. When 3wt% dispersant (sorbitan monooleate) is added to a matrix, the porosity of the matrix decreases a little while the bubble pressure and area of the matrix increase remarkably in comparison with no dispersant content. Effect of the electrolyte resistance and the polarization resistance on perfomance of a PAFC has been investigated using A.C. impedance spectroscopy. With the increase of whisker content, the electrolyte resistance decreases due to the increase of porosity and acid absorbancy, and the polarization resistance increases due to the increase of surface roughness. The polarization resistance affects current density predominantly at the higher potential than 0.7V becuase the polarization resistance is considrably larger than the electrolyte resistance. Both the electrolyte resistance and the polarization resistance affect current density near 0.7V of the fuel cell operating potential because they have similar values. The electrolyte resistance affects current density predominantly at the lower potential than the fuel cell operating potential because the electrolyte resistance is larger than the polarization resistance.

In this study compressive and tensile load tests have been performed to investigate reinforcing effect and load transfer mechanism of small diameter piles installed in the foundation soil for the marine suspension bridge. Load tests were carried out on steel plate with diameters of 50cm, 100cm and 150cm varying loads starting from 39 tons up to 314 tons. Small diameter piles were proved to behavior like as friction piles and loads were not transmitted to the bottom of piles. From pull-out tests, the uplift capacity of small diameter piles was largely influenced by reinforcing materials compared to frictional resistance between piles and adjacent soils. The bearing capacity of small diameter piles appeared to be higher than the ultimate bearing capacity evaluated using static formulae. The load carrying capacity of small diameter piles was superior to the bored piles with a similar size. Thus, ultimate bearing capacity estimated from static formulae can provide conservative designs and thereby resulting in economic disadvantages. A further study to accumulate data regarding various soil conditions is recommended for an improved estimation of bearing capacity of piles with small diameter.

Purpose: To evaluate the effect on clinical course of heterotopic ossification of distal tibiofibular syndesmosis after ankle fractures. Materials and Methods: From June 2001 to May 2004, we found nine cases of heterotopic ossification of distal tibiofibular syndesmosis after ankle fractures. There were 8 male patients and 1 female patient; their mean age was 42 years old. There were 6 Weber type B and 2 Weber type C fractures, and there is 1 case with posterior malleolus fracture only. Among them, 8 ankle fractures were operated. Follow up period was averaged for 14 months. We were able to review radiographs at initial injury and to review clinical menifestation and radiographs at last follow up. We used an ankle-hindfoot scoring system of AOFAS which combined symptom, function and alignment with maximum score of 100 point. Results: In all cases ankle dorsiflexion and plantarflexion were not significantly different from that of the contralateral side. The patients who had developed heterotopic ossification in distal tibiofibular syndesmosis had a similar functional score. The mean ankle-hind foot score was 94 points. Conclusion: We concluded that the heterotopic ossification of distal tibiafibular syndesmosis after ankle fractures had little effect on clinical course and range of motion of ankle joint.

Purpose: The purpose of this study was to investigate the differences in simple radiographic parameters and results of 3-D scan among normal and patient groups. Materials and Methods: Seventy subjects in each group were studied. Control group consisted of subjects without plantar foot pain (normal group), and two patient groups were one with plantar forefoot pain (metatarsalgia group), the other with plantar heel pain (heel pain group). Simple radiographic parameters were obtained and 3-D scan was done with foot scanner (Nexscan, K&I, Korea) and The height and volumn of the space under the medial longitudinal arch was analyzed (Enfoot, K&I, Korea). These parameters were compared and correlation between radiological parameters and results of the 3-D scan were studied. Results: The results of all parameters istributed normally. There was no signigicant differences among the groups in radiological parameters (talo-first metatarsal angle, calcaneal pitch angle and height of the talar head in standing lateral radiograph) and arch height and arch volumn on 3-D scan. There were statistically significant correlations between radiological and 3-D scan results. Conclusion: This study revealed that there is no significant differences in medial longitudinal arch height and volumn among normal and different patient groups and there are variety of arch height in patients with similar symptoms.

Fashion has been analyzed and explained in diverse ways. Fashion, like every phase of culture, is a reflection of the Zeitgeist. In order to understand the changing fashion we must understand the changing society. For fashion of a period are expressions of the interrelation of the various elements of the culture, including the social and political values, the economic and industrial progress, art, the development of technology, etc... Particularly fashion is closely connected with a style of art. In a style of art, futurism focused on the "dynamism" resulting from super-speed and high-technology. This study aimed to review literatures, fashion magazines, web-site in order to know how the dynamism of futurism is expressed in modern fashion. The results of this study were as follows; 1. Dynamism was expressed by means of lines, colors, patterns through the eyesights visually. Asymmetrical oblique lines, zig-zag lines or bold cutting expressed the mechanical and offensive dynamism. In contrast, such lines as curves and spirals expressed the soft and natural dynamism. Primary colors or complementary contrast expressed energetic and rhythmical dynamism. The geometrical patterns and automobile wheels patterns expressed dynamism resulting from mechanical aesthetics. 2. Dynamism was expressed through repeat of lines, colors, patterns, and textiles. Particularly Vinyl material, fluorescent material, metallic material, beads, and spangle expressed a strong dynamism. On the other hand, natural materials, paper and other similar ones are used to signify the orientation towards a futuristic high-technology society.y society.

Social media which support to share information and communicate between online users have recently won great popularity. Of the various social services blogs have played an active role as a community in sharing delivering and exchanging information among individual users who have share similar opinions hobbies and preferences. Based on this cultural phenomenon some companies often take advantage of blogs as a marketing tool to strengthen their public relations or deliver particular information to their costumer. This study is designed to classify fashion-related blogs and define the characteristics of each type expecting significant influences on future studies on this topic. We selected 50 fashion-related blogs as subjects including 25 Korean blogs and the same number of international blogs, defined their characteristics and classified them into four different types. As the result we found that there are apparent differences between the four types of blogs: "Individual taste" blogs which noticeably reflect bloggers' own preference "Trend leader" blogs in which the bloggers intend to be trend leaders beyond expressing their preference "Fashion media" blogs which plays a significant role as a magazine by providing various information concerning fashion for costumers and "Sales promotion" blogs which are used as promotional materials to attract customers by providing product reviews or advertisements.

Since the reliability of adhesively bonded joints is much dependent on the curing status of thermosetting adhesive, the on-line cure monitoring during the cure of adhesively joints could improve the quality of adhesively bonded joints. In this work, the dielectric method which measures the dissipation factor of the adhesive during the cure of joints and converts it into the degree of cure of the adhesive was devised. The relation between the dissipation factor and the degree of cure of adhesive was investigated, which could eliminate the temperature effect on the dissipation factor that is a strong function of the degree of cure and temperature of adhesive. From the investigation, it was found that the dissipation factor showed a trend similar to the cure rate of the adhesive.

Purpose: To describe technical methods for functional magnetic resonance imaging (fMRI) study with arterial spin labeling (ASL) compared to blood oxygenation level-dependent (BOLD) technique and discuss the potential of ASL for research and clinical practice. Materials and Methods: Task-based (n = 1) and resting-state fMRI (rs-fMRI) (n = 20) were performed using ASL and BOLD techniques. Results of both techniques were compared. Results: For task-based fMRI with finger-tapping, the primary motor cortex of the contralateral frontal lobe and the ipsilateral cerebellum were activated by both BOLD and ASL fMRI. For rs-fMRI of sensorimotor network, functional connectivity showed similar results between BOLD and ASL. Conclusion: ASL technique has potential application in clinical and research fields because all brain perfusion imaging, CBF measurement, and rs-fMRI study can be performed in a single acquisition.
