To examine the attitude of students toward animals and its relation to veterinary ethical decision making, 302 pre-veterinary and veterinary students of three national universities (Seoul, Chungbuk and Kyungsang National University) were requested to answer the Animal Attitude Scale Test, an indicator of one's pro-animal attitude. A significant gender difference in the AAS scores was found with higher scores in females (female vs. male, 65.27 vs. 57.40; p < 0.0001). The students who have companion animals had higher AAS scores (62.55) than those who donot (58.03, p < 0.0001). However, years of study and experience with animal protection activities did not affect the AAS scores. The correlation between the attitude toward animals and ethical decision making was found in the investigation with two cases of a veterinary ethical dilemma: the medical treatment of a cow in its last gestation stage with ocular squamous cell carcinoma and the euthanizing of a 12 year-old dog with urinary incontinence. The students tend to support for veterinarians to influence clients' decisions in treatment by using their power as medical professionals, even if doing so could partly damage the interests of the clients or patients. The significant correlations between the AAS scores and veterinary ethical decision making were found in this study, which implies that the attitude toward animals should be considered as one of the major factors in making ethical decisions in veterinary practice.

To find compounds of immunomodulating and anti-allergic function, effects of protein-bound polysaccharides extracted from Phellinus igniarius (PI), Fomitella fraxinea (FF) and Agrocybe cylindracea (AC) on hemagglutinin titer (HA), hemolysin titer (HY), plaque forming cell (PFC), rosette forming cell (RFC) and phagocytosis were investigated in BALB/C mice. The oral administration of the protein-bound polysaccharides of PI, FF and AC for 10 days resulted in the enhanced phagocytic activity of peritoneal exudate cells (PEC), spleen cells (SC) and blood lymphocyte cells (BLC). Moreover, PI showed the activating effect on the phagocytosis of PEC and AC in SC. In the experiment of PFC and RFC, the results of the experimental group which was given each samples as compared to the control group, showed the enhanced level of activity such as PI 130%, FF 90% and AC 70%. Generally, HY and HA showed from ten to hundred times of level in each sample groups, as compared to the control group.

This article investigates 295 social workers in order to find out how much they believe that each behavior related to dual relationships is ethical and with how many clients they engaged in these behaviors. This article, based on the literature, explores three areas of dual relationships which are sexual, bartering, and private dual relationships. The results from the research were 1) The social workers tend to believe that while sexual and bartering dual relationships are less ethical, private dual relationships are more ethical. Meanwhile, they have little experience to engage in all areas of dual relationships; 2) Compared to beliefs and experiences, the social workers believe that each behavior is ethical, but they have less experienced the same behavior. However, the result of strong correlations between beliefs and experiences shows that the more the social workers believe that the behaviors are ethical, the more they tend to engage in the behaviors; 3) Based on socio-demographic characteristics, male social workers tend to accept dual relationships as ethical behavior than their female counterparts do. And those who are practicing in health settings tend to believe that the behaviors related to dual relationships are less ethical than those who are practicing in the other areas of the profession do. Finally, the research recommends that enhancing social worker's self-awareness and professional maturity is needed in order to prevent the occurrence of dual relationship engagement. Also, social work professional associations and agencies should provide education, training, and institutional restrictive devices for dealing with unethical dual relationships.

The properties of the natural zeolite produced in Kuryongpo, Kyungsang-Bukdo, were investigated by X-ray diffraction analysis, chemical composition analysis, and nitrogen adsorption experiment. The quality of the acid treated natural zeolite as the catalyst for the disproportionation reaction of toluene was examined experimentally by observing the conversion in a microcatalytic reactor. The quantitative analysis and X-ray diffraction spectrum showed that the zeolite ore of Kuryongpo contained approximately 30 to 40 percent of mordenite structure. The surface area of the zeolite ore was $75m^2$/gm and increased to a maximum value of $320m^2$/gm after treatment with 2 N HCl solution. The catalytic activity for the toluene disproportionation reaction was maximum when the zeolite treated with 2 N HCl solution was used. The selectivity of xylene to benzene decreased with increasing degree of acid treatment.

This study was conducted to obtain the transgenic Brnssica napus plants with tobacco Apase gene using the binary vector system of Agrobacteriurn fumefociens. The results obtained were summarized as follows: A repressible acid phosphatase gene of Saccharon~yces cerevisiae, pho105 was used for screening of tobacco Apase cDNA. In order to identify Apase gene in tobacco genome, Southern blot analysis was pcrformed and the Apase gcnc may be present as a single copy, or at most two or three copies, in tobacco genome. To isolate the tobacco Apase gene, tobacco cDNA library was constructed using purifed mRNA from -Pi treated tobacco root and the plaque forming unit of the library was 2.8 x $10^5$ pfu/m${\ell}$, therefore the library might cover all expressed mRNAs. Using pho5 as a probe. tobacco Apase cDNA was cloned, and restriction mapping and Southern blot analysis of cDNA insert were revealed that the 3.6 kb cDNA contained tobacco acid phosphatase cDNA. Plasmid pGA695 -tcAPl was constructed by subcloning tobacco Apase cDNA into the Hind site of pGA695 with 35s promoter which can be expressed constitutively in plants. The Brassica napus cotyledonary petioles were cocultivated with the ,4 grobacteriunz and transferred to the selection medium. The transformed and regenerated plants were transplanted to soil medium. Southern blot analysis was done on the transformed plants, and it was confirmed that a foregin gene was stably integrated into the genonies of B. nnpus plants.

Dokdo is a volcanic island, and its formative geological age took place at the end of the Pliocene Epoch. Dokdo is located at 131。 52′33" East longitude, and 37$^{\circ}$ 14′18" North latitude, and is consituted of 87 islands. The total area of Dokdo is 0.186 $\textrm{km}^2$ and the length of its coastline is 4 km. Ookdo is a treasury of fish resources where many varieties of fish including squid and Alaska pollack live in abundance of greatest importance. Dokdo is a forward fishery base. Ullung island is located at 37$^{\circ}$ 27′~37$^{\circ}$ 33′North latitude and 130$^{\circ}$ 47′~130$^{\circ}$ 56′East longitude. The area of Ullung is 72.92 $\textrm{km}^2$ and the length of its seashore is 44.21 $\textrm{km}^2$. The total marine product of Ullungdo(1995) is 9,066 tons (M/T). The largest is squid, 8,900 tons. For the sea area of the depths near the Ullungdo, coast, that of 50m or less is 2,477 ha, and that of 50- 100m is 1,471ha. This fact tells us that there is no extensive area of a very shallow sea, and that it is directly connected to the deep sea. Ullungdo is a treasury of marine bioresources with rich and varied fishes including squid and Alaska Pollack and many others. Presently there is a sovereignty dispute over Dokdo between Korea and Japan. Since A.D.512, Dokdo has been a part of territory of Korea. Dokdo is a part of Kyungsang-Bukdo, Ullung-gun, Ullung-up, Do-dong in the Korean administrative district division system. Japan strenuously claims sovereignty for significant economic reasons, including fishery rights, and has adhered to a contradictory position that "Dokdo is Japanese land" since Japan incorporated Dokdo into Japanese territory in 1905.ritory in 1905.

Dragomiretskiy and Zosso (2014) developed a new decomposition method, termed variational mode decomposition (VMD), which is efficient for handling the tone detection and separation of signals. However, VMD may be inefficient in the presence of missing data since it is based on a fast Fourier transform (FFT) algorithm. To overcome this problem, we propose a new approach based on a novel combination of VMD and hierarchical (or h)-likelihood method. The h-likelihood provides an effective imputation methodology for missing data when VMD decomposes the signal into several meaningful modes. A simulation study and real data analysis demonstrates that the proposed method can produce substantially effective results.
