Purpose: This study was done to investigate behavior related to viewing pornography sites by primary, middle, and high school students in one province. Methods: The participants were 2,939 primary (5, 6 grade), middle and high school students (1, 2 and 3 grade), chosen at random in big cities, small towns and rural areas of North Cholla Province. Results: The first experience of finding pornography sites by oneself was 21.1% for the total sample and for primary school students 6.8%, for middle school students, 31.0%, and for high school students, 62.2%. The first time on a pornography site was highest for middle school students (62.0%) and for grade, middle school 1 grade (25.7%). The pornography use resulted in difficulties with study (11.3%), desire to imitate what was seen in pornography (10.9%), imitation of what was seen the pornography (3.9%), and desire to visit pornography sites everyday (2.3%). Pornography contact behavior was related to gender and school type (p<.05). Independent access to pornography and experiencing difficulties with study were related to area of residence (p<.05). Conclusion: These findings suggest that systematic education policy and further research on needs for pornography contact should be examined to develop programs to decrease pornography contact behavior.

A total of 62 isolates of Bipolaris cactivora causing cactus stem rots were isolated from major cactus-growing areas in Korea. Colony morphology of the isolates on potato-dextrose agar was differentiated into aerial (CA) and non-aerial mycelial types (CB). CA had profound aerial mycelium with grayish brown (CA-l), light brownish (CA-2), and brownish (CA-3) pigmentations; respectively, while CB had dark brownish pigmentations. CA had conidia of less dark pigmentation and acute terminal end. CB had darker and more round-end conidia. Twenty-eight amplified fragments were produced by polymerase chain reaction (PCR) with a set of 2 random primers. The sizes of amplified DNA fragments ranged approximately from 0.1 to 2.3 kb. The isolates were classified into 2 major genomic DNA random amplified polymorphic DNA (RAPD) groups at the genomic similarity of 97.7％ and 95.1％, respectively. Cluster analysis of genetic similarity among the isolates generated a dendrogram that clearly separated all isolates into SA or SB. This result suggests that there may be two morphotypes of B. cactivora in Korea that may differ in their genetic constitutes.

The purpose of this study is to identify the current status of the working poor and the factors that are influential to the working poor among echo boomers. This study is a secondary analysis using the data from the 7th analysis of the 2012 Korea Welfare Panel Survey, conducted by Korea Institute for Health and Social Affairs. This analysis considered Korean echo boomers born between 1979 and 1985. In our final analysis, we used 1,226 echo boomers who had the ability to work. For the analysis, the SAS/PC statistical program ver. 9.3 was utilized. The research findings are as follows; Firstly, of the working poor among the echo boomers, only 22% were in the state of poverty. Secondly, more echo boomers living in a metropolitan city, city, gun/urban-rural area and district than those in the Seoul were categorized as among the working poor; the same was true for those who lived in a free house than in a leased room or a room that was rented by the month. Thirdly, more echo boomers whose education level was high school graduate or less rather than college graduate or less or university graduate or more were categorized as among the working poor; this was also true for echo boomers whose employment type was temporary employment, self-employment, or unemployment rather than a full-time job.

Evaluation in both an art and a science. The art of evaluation involves working with the management to agree upon purpose and users of results, creating design and gathering information that are appropriate for a specific situation and a particular policy making context. The value of evaluating extension p개grams has received a lot of attentions recently, and many extension educations see evaluation as an integral part of their work. The science of evaluation involves determining standards and developing indicatiors, selecting methods appropriate to gather information in a systematic way, analyzing information to assist in determining the value of the program in an objective manner. First, extension specialists have to consider relative merits about methods of gathering evaluation data. Selection of method should be influenced by the type of information desired, time availability, and cost of using the method. Second, good evaluations involve stakeholders at all stages including planning, implementation, and utilization of results. Third, far from being an "add-on ," evaluation begins with the initial planning of an educational program. Fourth, it is important for extension specialists that although evaluation is valuable and essential in any effective program, one of the biggest mistakes of extension program evaluators in to promise results that cannot possibly solve all the problems of project.

Paprika (Capsicum annuum L.) contains various phytochemicals, including carotenoids, ascorbic acid, tocopherol, flavonoids, and phenolic compounds, as well as natural food colorants. Very little information is available regarding wine produced from different colored paprikas. The objectives of this study were to prepare wines from red, orange, and yellow paprika and evaluate their physicochemical characteristics. The alcohol concentration, pH, titratable acidity, and reducing sugar content were not significantly affected by the type of paprika. Hunter's color values varied with the color of paprika. The total mineral content and 2,2-diphenyl-1-picrylhydrazyl radical scavenging potential of red paprika wine were significantly higher; however, the total polyphenol content of yellow paprika wine was significantly higher than that of the other wine samples. This study suggested that paprika could be used to prepare wine and red paprika might be appropriate for producing good-quality wine.

Of all the various types of tea that are available, Pu-erh tea has attracted much attention because of its healthpromoting effects. The objective of this study was to investigate the physicochemical and antioxidant properties of two types of Pu-erh tea, Gushu Pu-erh and typical Pu-erh, extracted at 80 and 100℃, respectively. The Gushu Pu-erh extracts showed lower pH but higher antioxidant potential at both the temperatures, as compared to the typical Pu-erh. The mineral content of the tea extracts was greater at 100℃ than at 80℃. Among the seven categories of the flavor compounds that were detected, the peak area of esters was the highest in the Gushu Pu-erh extracts. The type of tea and the extraction temperature significantly affected the physicochemical and functional properties of these tea extracts. This study revealed that Gushu Pu-erh extracted at 100℃ for 3 min with 30 s of shaking provides better results in terms of the antioxidant potential and mineral content.

We generated transgenic tomato plants with Arabidopsis thaliana $H^+$/cation exchanger gene (C4X4) by Agrobactrium-mediated transformation. We confirmed transgene copy number and transcription by Southern and Northern blot analyses. The intact CAX4-expressing tomato (Lycopersicon esculentum) fruits contained 63-71% more calcium ($Ca^{2+}$) than wild-type fruits. Moreover, ectopic expression of C4X4 in tomato fruits did not show any significant increase of the four kinds of metallic cations analyzed ($Mg^{2+}$, $Fe^{2+}$, $Mn^{2+}$, and $Cu^{2+})$. The C4X4-expressing tomato plants including their fruits did not show any morphological alternations during whole growth period. These results suggest the enhanced Ca-substrate specificity of CAX4 exchanger in tomato. Therefore, intact CAX4 exchanger can be a useful tool for $Ca^{2+}$ nutrient enrichment of tomato fruits with reduced accumulation of undesirable cations.

The purposes of this study were to explain consumer attitude, behavioral intention and behavior(expenses) in the purchase of Han-gwa and to explore the influencing factors on them. To achieve these purposes, the Heckman two-step model was utilized to utilize the recursive system of attitude, behavioral intention and behavior. The results of this study were as follows: 1) Seventy-six percent of consumers presented their favorable altitudes to purchase Han-gwa, while $47\%$ of consumers had behavioral intention for purchasing Han-gwa. In addition, purchasing expense of Han-gwa per year as a proxy variable of behavior was less than 100,000 won for most consumers. 2) First, consumer attitude was found to be significantly influenced by the type of family and food safety. Second, the behavioral intention for purchasing Han-gwa was found to be significantly influenced by consumer attitude, age, income, education and price. Finally, consumer behavior(expenses) of purchasing Han-gwa was found to be significantly influenced by the behavioral intention, income and purchasing place.
