The 3D building modeling is one of crucial components in constructing 3D geospatial information. The existing methods for 3D building modeling depend mainly on manual photogrammetric processes, which indeed take great amount of time and efforts. In recent years, many researches on 3D building modeling using aerial LiDAR data have been actively performed to aim at overcoming the limitations of existing 3D building modeling methods. Either techniques with interpolated grid data or data fusion with digital map and images have been investigated in most of existing researches on 3D building modeling with aerial LiDAR data. The paper proposed a method of 3D building modeling with LiDAR data only. Firstly, octree-based segmentation is applied recursively to LiDAR data classified as buildings in 3D space until there are no more LiDAR points to be segmented. Once octree-based segmentation is completed, each segmented patch is thereafter merged together based on its geometric spatial characteristics. Secondly, building model components are created with merged patches. Finally, a 3D building model is generated and composed with building model components. The experimental results with real LiDAR data showed that the proposed method was capable of modeling various types of 3D buildings.

A liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI/MS/MS) method was developed for the determination and confirmation of clenbuterol in bovine muscle and milk. Clenbuterol and clenbuterol-D9 using as an internal standard in samples were extracted with ethyl acetate after hydrolysis and evaporated to dryness. The extracts were dissolved in 20% methanol and cleaned using HLB solid-phase extraction cartridge. The analytes were detected by LC-ESI/MS/MS on a $C_{18}$ column. Mass spectral acquisition was done in selected reaction monitoring (SRM) in positive ion mode to provide a high degree of sensitivity. Using MS/MS with SRM mode, the transitions (precursor to product) monitored were m/z 277${\rightarrow}$203 for clenbuterol, and m/z 286${\rightarrow}$204 for internal standard. The limits of quantitation (LOQ) and mean recoveries of clenbuterol in bovine muscle were $0.2{\mu}g/kg$ and 84.3~91.1%, respectively. The LOQ and mean recoveries in milk were $0.05{\mu}g/kg$ and 87.7~98.3%, respectively.

Mandipropamid is a new mandelamide-type fungicide to control foliar Oomycete pathogens in some vegetables. An analytical method was developed to determine mandipropamid residues in agricultural commodities using high-performance liquid chromatography (HPLC) and liquid chromatography/mass spectrometry (LC/MS). Mandipropamid was extracted with methanol from grape, tomato, green pepper, Chinese cabbage and potato samples. The extract was diluted with saturated sodium chloride solution and distilled water, and dichloromethane partition was followed to recover the mandipropamid from the aqueous phase. Florisil column chromatography was employed to further remove interfering co-extractives prior to HPLC analysis. Reverse-phased HPLC was successfully applied to determine mandipropamid in sample extracts with the detection at its ${\lambda}_{max}$ (223 nm). Overall recoveries of mandipropamid from fortified samples averaged $99.8{\pm}1.7$ (n=6), $89.3{\pm}5.3$ (n=6), $98.7{\pm}2.2$ (n=6), $99.7{\pm}6.8$ (n=6) and $91.1{\pm}3.1$ (n=6) for grape, tomato, green pepper, Chinese cabbage and potato, respectively. Limit of quantification of the method was 0.02~0.04 mg/kg for all samples. A LC/mass spectrometry with selected-ion monitoring was also provided to confirm the suspected residue. The proposed method was reproducible and sensitive enough to determine the terminal residue of mandipropamid in agricultural commodities.

This study intends to divide consumer's psychological attachment of pro-sport into the identification of attitudinal dimension and the identification of behavioral dimension. And then intends to examine the relationship effect between motivation variables associated with pro-sport team(concern with the team's ranking, ability of players, attraction of players) and inspection intention, sponsorship effect(sponsor brand attitude). Almost all previous studies measured such relationship at the fragmented level, then there were no previous studies on the complicated relationship between sport team and sponsorship. Because of mentioned facts, this study used structure equation model to verify such relationship. Briefly, verifying hypothesis is as follows. First, almost all motivations related to the team are connected behavioral identification through attitudinal identification. Second, when examining the relationship between psychological attachment and inspection intention, sponsorship brand attitude, psychological attachment had positive effect on inspection intention and sponsor brand attitude in the case of attitudinal identification, but it had positive effect on only inspection intention in the case of behavioral identification. Findings and corresponding implications are discussed & future research directions.

Yukwa was prepared with the glutinous rice by the addition of different ratio of pigmented rice (0, 3, 5, 7, 10%) and were steeped for 7 days at 20$^{\circ}C$. No significant differences were found among the samples when the textural properties of Yukwa dough and base were measured using a texture analyzer. But the crispness was decreased with tile increase of the addition level of pigmented rice. The redness (a value) and yellowness (b value) of the dough and Yukwa base were increased and the lightness (L value) was decreased as the addition levels increased. The expansion rate of Yukwa was decreased with the increase of addition levels. The overall acceptability of Yukwa prepared with the addition of 7% pigmented rice was the best in the sensory evaluation.

Texture, losses of total solids and proteins o) soybeans were studied during cooking at $100-135^{\circ}C$. The textural changes were measured using the puncture probe with an Instron Universal Testing Machine, and changes in microstructure of beans were observed with scanning electron microscopy during the cooking. The major effect observed was a breakdown of the cell walls and appearance of the protein bodies with soaking process. As the cooking time at $100^{\circ}C$ is longer, the separation of cells and changes in cell shape could be seen in the sample. The greater amounts of soluble solids were leached out with longer coo king time from the beans.

It is a tentative study on the influence of the consumers' motivation of charity impulse on their loyalty who donate to non-profit organizations. Based on the self-determination theory, this thesis paper analyzed the motivation of charity impulse on non-profit organizations which is the main factor influencing the donation loyalty with consumer-nonprofit identification as parametric variables. According to this study, it seems that the charity impulse caused by the concepts of autonomy of the self-determination theory has negative influence on consumer-nonprofit identification, donation loyalty. But relation-competence has positive influence to nonprofit organizations. Considering without any studies on donators' motivation of charity impulse from the aspect of psychology to non-profit organizations, as the very initial exploratory study, this study is conducted to analyze the possible factors to influence customers' motivation of chanty impulse on the basis of the self-determination theory so that it has a vital significance, which can furnish fundamental data to charitable organizations to carry out effective marketing strategies to guarantee the source of the money collection.

Objectives: This study aimed to investigate factors related to prostate disease and follow-up procedure on health examination program in Gangwon-do. Methods: The studied population was 16,501 male aged 40 or more, who underwent screening tests for prostatic disease in 2011 health examination program designed for the low income residents in Gangwon-do. The screening tests included prostate specific antigen (PSA), international symptom score (IPSS), and maximal flow rate (Qmax). We conducted chi-square test for trend, two independent samples t-test, and binary logistic regression to find out the relationship between prostate cancer or benign prostatic hyperplasia and risk factors such as age, PSA level, and IPSS. Results: The number of subjects who turned out positive for PSA level (> 3.8ng/ml) was 971 men accounting for 5.9%. The result of post survey on them showed that 511 subjects (52.6%) got the urology check-up: 156 (30.5%) were diagnosed as normal, 286 (56.0%) as benign prostatic hyperplasia, and 69 (13.5%) as prostate cancer. The detection rate for prostate cancer was 8.8% when PSA level was between 3.81 and 9.99g/ml, and was 30.6% when PSA level was more than 10.00ng/ml. The rates of further testing varied depending on the communities from 26.7% to 68.2%, which was mainly affected by the role of local health center. Conclusions: Our findings indicate that enhanced quality control of local health center and empowerment of screening agency would increase the effort of coupled institutions between public and private sectors.

A unified method for separating musical sources, singing voice for example, from stereophonic mixtures is provided. We usually have two observed signals in stereophonic music contents, where more than two instruments are played together. If we regard each instrument as source, this problem becomes an underdetermined source separation problem and cannot be solved by conventional methods, which infers the spatial environment of the downmixing process happens. Instead, source-specific information has been exploited to recover a particular instrumental source. This paper provides a unifying structure consists of heterogenious ad-hoc separate algorithms, which are designed for separating vocal sources using stereophonic channel information and dominant pitch information of the sources, respectively. Experiments on real world music contents show that the proposed unification can neutralize the drawbacks of the two ad-hoc separation algorithms and finally enhance the separation results.
