  • Peri-partum metabolic profile was evaluated in winter and summer calving, with 15 Murrah buffaloes in each seasonal group. In summer calvers, significantly lower values were observed for blood plasma urea nitrogen (BUN) at day 30 pre-partum (p<0.05), on calving day (p<0.05) and at all other stages (p<0.01); plasma non-esterified fatty acids (NEFA) values were significantly lower on day 30 pre-partum (p<0.01) and on day 60 post-partum (p<0.05). This was associated with significant reduction in days to first service (DFS) and service per conception (SPC) and an overall better reproductive performance in terms of service period, risk to first service on days 60, 90 and >90, and pregnancy risk to first service up to days 60 and 90. This may be attributed to better pre-partum nutritional status. Cervical and uterine involution were completed in fewer days, involutional changes took place at a faster pace and there were a lower number of abnormal involutional changes in winter compared to summer season. This may be attributed to better post-partum nutrition and less environmental stress. However, validation requires further targeted cohort investigation with a large sample size.

  • Particles of soil are crushed when soil is compacted in the in-situ or lab. Among many factors that affect the crush of particles, compaction energy is a major factor. Because the crush of particles can change physical properties, the analysis of effect of compaction energy is very important. In this study, the fragmentation fractals were used for determining the change in grain size distribution and the effect due to change in grain size distribution was estimated. Compaction energy was increased by 50, 100, 200 and 300% based on the energy of standard A compaction test. As a result, grain size distribution curves were changed and fine particles increased as compaction energy were increased. Relative compaction were ranged between $93.38{\sim}107.67$. Fractal dimension of each site increased as compaction energy increased. Relative compaction is proportional to the fractal dimension but coefficients of permeability were in inverse proportional to the involution of fractal dimension.

  • Gluconacetobacter diazotrophicus strain PA15 exhibited a minimum inhibitory concentration value of 11 mM in an LGI medium amended with $ZnCl_2$. When an LGI medium was amended with Zn metal, solubilization halos were observed in a plate assay, and further solubilization was confirmed in a broth assay. The maximum solubilization was recorded after 120 h with a 0.1% Zn metal amendment. During solubilization, the culture growth and pH of the broth were indirectly correlated. Using a Fourier Transform Infrared Spectroscopy analysis, one of the agents solubilizing the Zn metal was identified as gluconic acid. When the Zn-amended broth was observed under a bright field microscope, long involution cells were observed, and further analysis with Atomic Force Microscopy revealed highly deformed, pleomorphic, aggregate-like cells.

  • Infantile hemangiomas have a growth phase and an involution phase. For this reason, serial observation has generally been recommended as the treatment for uncomplicated infantile hemangiomas. Recently, however, individualized approaches have been emphasized. Although cleft lip and infantile hemangioma are common congenital diseases, infantile hemangiomas on the cleft side (i.e., in the operative field of the cleft lip) are extremely rare, and no clear guidelines have been established for their treatment. We experienced a case in which a patient with a cleft lip had an infantile hemangioma on the cleft side. In accordance with general treatment guidelines, cleft repair was performed 3 months after birth. The Millard rotation-advancement technique, which involves the use of a lower small triangular flap, was used for the repair. No intraoperative complications, such as massive bleeding, or postoperative complications were noted. The patient has received regular follow-up for the past 18 years, and other than a reddish scar on the lower lip, he currently has no related issues. Therefore, this case demonstrates that cleft lip repair performed according to cleft lip treatment guidelines produces good outcomes, even in cases involving a hemangioma on the cleft side.

  • An epizootic of calf diarrhea occurred in an extensive dairy farm located in Gangwondo province in December of 1985. The patients showing fever, chills, complete anorexia and watery diarrhea sometimes dysentery were concentrated among the calves ranged from 8 days to 3 months old and many of them died in acute course. The five carcases were examined by pathological and bacteriological means. The predominant gross lesions were edematous swelling of the mesenteric lymph nodes, profuse catarrhal or diphtheritic enteritis and extensive purulent bronchopnenomonia or lobar fibrinous pneumonia. Microscopically the lesions of the liver and spleen were characterized by coagulative necrotic foci and granulomatous nodules. The spleen and lymph node showed also proliferative changes of reticular cells and involution of intestinal lymphatic nodules were noticed. The strains of Salmonella(S) species isolated from the liver, spleen, bile juice, peritoneal fluid and thoracic fluid were identified serologically as S. dublin. These clinical and pathological findings of the disease were those of acute enteritis form of salmonellosis and characterized by high morbidity and mortality among the calf herd. The report also signifies the first description of an epizootic of bovine salmonellosis caused by S. dublin in Korea.

  • The hair cycle consists of three phases, growth (anagen), involution (catagen) and quiescence (telogen) phases. In order to evaluate hair re-growth effect of herbal extracts mixture containing the 70% ethanol extracts of Polygoni Multiflori Radix, Mori Cortex Radicis, Gingko Biloba Folium and Pine bud, we have examined the induction of the anagen phase and/or elongation of the anagen period using C3H mice. Morphological examination was done by Hattori' and Ogawa's method. Enzyme activities of ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GT) and alkaline phosphatase (ALP) was detected by Bessey-Lovry-Brock's method. Enzyme activity as a biochemical marker of hair cycle was investigated in the third hair cycle period of C3H mice after depilation. 3% Minoxidil treated group and herbal extract mixture treated group were shown 3 days earlier initiation of anagen than control group. In cycling mouse skin, ${\gamma}$-GT activity is pronounced during anagen and greatly diminished during telogen. Herbal extract mixture has shown promising hair re-growth effect on hair follicular cycles of C3H mice.

  • The investigation on the previous paper(Jn. of KoSSGE vol.12, no.3), which proposed three empirical equations for the different aquifers was carried out. To draw out a single equation from the three different equations the mean value of the involution factors was adopted allowing different proportional coefficients for the different aquifers. On the other hand it was found that the square root value of storativity ratio, ${\sqrt{{S_p}/{S_o}}}$ in each well is almost equal to its wellbore radius ratio, ${r_e}/{r_w}$. From this fact, the proportional coefficients can be substituted with assumed aquifer storativity and a generalized empirical equation for the effective wellbore radius has been derived.

  • This research focuses on developing the Smart material with Grease adopted as a base oil to overcome a particle deposition caused by the MR fluid consisting of a silicon, which maximizing the characteristics and advantage of the MR fluid. By adopting the SMG fluid to a shear damper, this paper aimed to evaluate the control performance of it according to the variation of intensity of electric current(0 A, 0.5 A, 1.0 A, 1.5 A, 2.0 A, 2.5 A) and frequency(0.5 Hz, 1 Hz, 2 Hz). Subsequently, the usability of the SMG damper was analyzed by comparing the dynamic model of it to that of the other types of dampers(Power(Involution) Model, Bingham Model). As a result, DR, the performance indicator of semi-active damper, shows approximately 5 in a condition of 2 Hz. Also while confirming the excellent performance like the Power and the Bingham model, it raises the possibility to exploit it as the semi-active damper.

  • The peasant societies of East Asia had been challenged by capitalist plantation since colonization and by socialist collectivization since decolonization. The former was decisively weakened due to the crisis of the capitalist system in the 1930s and the collapse of the colonial order in the 1940s; The latter was thoroughly discredited due to the reform of the socialist system in the 1980s and the end of the Cold War in the 1990s. The failure of the two epochal challenges demonstrates the historical sustainability of peasant societies in East Asia. Their survival represents the universality of Northeast and Southeast Asia, which can be ascribed to the ecological environment and production process of wet-rice agriculture for their common staple food. In spite of their diverse differences, indeed, peasant societies in colonial East Asia shared profound similarities in their basic motivations (morality-rationality), central tendencies (involution - polarization), structural outcomes (dualism - pluralism), and future prospects (survival-extinction).
