  • Nonunion of the hallucal sesamoid usually occurs after stress fracture. In case of persistent disabling symptoms after non-operative treatment, surgery can be an option. We report a rare case of combined stress fractures of the medial bipartite sesamoid and the lateral sesamoid after overuse. Nonunion of the medial sesamoid developed in spite of cast immobilization, and it was eventually healed with curettage and bone grafting.

  • This study was performed to investigate the bionomical characteristics of Protaetia brevitarsis in Korea. The imaginal stage was from in early July and the advent of imagoes was the most frequent in early August. Also few imagoes was entered into the hibernation. The larvae inhibited in humus and the period of larva was all completed in late November. At the stage of the third larva, the larvae entered into the hibernation. The average number of laid eggs was 152, and all periods of each stage - eggs, first, second, third instar larvae and pupa - were shortened in $30^{\circ}C$ than in $25^{\circ}C$. As for the longevity of imagoes, female, reared in individual and in low temperature lived longer than male, in group and in high temperature, respectively.

  • Room-and-pillar mining method is one of the most popular underground mining method in the world. If the room-and-pillar mining method is able to be adopted in civil works, it would be highly probable to reduce underground construction costs and to expand a underground structure in use. Therefore, this study aims to analyze the design procedure of unsupported rock pillars which are indispensable to ensure the stability of a room-and-pillar underground structure. Parametric studies on their key design parameters are also carried out for 125 different kinds of design conditions. From the study, the width of a rock pillar is found to show a linear relationship with its corresponding safety factor. The safety factor of a unsupported rock pillar decreased drastically like a negative exponential function as the ratio of room width to pillar width increases in the same rock strength condition. Based on the parametric studies, a design chart to simply evaluate the geometric design parameters of a unsupported rock pillar satisfying a design safety factor is also proposed in this study.

  • Multiple surgical procedures for the correction of hallux valgus have been described. The surgical algorithm is based on the degree of deformity, patient's age, and the presence or absence of arthritis. It is known that the role of an isolated distal soft-tissue procedure is limited and the procedure must be used in conjunction with the proximal metatarsal osteotomy to correct most hallux valgus. We reviewed retrospectively the clinical & radiological results of distal soft-tissue procedure with or without proximal metatarsal osteotomy, performed in 18 patients (29 cases ) who had mild to moderate degrees af hallux valgus deformity. The results were as follows : In 20 cases with isolated soft-tissue procedures, the preoperative hallux valgus angle (HV) averaged 30.6 degrees and the postoperative HV averaged 7.3 degrees. The preoperative intermetatarsal angle (IM) averaged 12.5 degrees and postoperative IM averaged 10.4 degrees. 2. In 9 cases with the proximal metatarsal osteotomy added, the preoperative HV averaged 32.5 degrees, and the postoperative HV averaged 8.0 degrees. The preoperative IM averaged 12.5 degrees, and postoperative IM averaged 10.1 degrees. 3. There was no significant difference of loss of correction, presence of complication, patients own satisfaction, between two groups. In conclusion, as for the patients with mild to moderate degrees of hallux valgus deformities, the clinical and radiological results following distal soft tissue procedure and proximal metatarsal osteotamy are not proved to be superior to those following isolated soft-tissue procedures.

  • Effects of feeding browses on growth and meat quality of Korean native goats were investigated. Twenty eight heads of male goats were divided into four treatment groups fed diets containing oak browse, pine browse, fermented pine browse, and rice straw. Growth rate, feed intake, carcass and meat quality and blood and serum criteria were investigated. The highest average daily gain of goats was 45.3g from oak browse, and goats on pine browse gained similar to those on fermented pine browse. Daily forage intake was 197g DM for oak browse and 74g DM for fermented pine browse. Feed efficiency(g feed/g gain) of oak browse was 11.0g and that of pine browse was 15.1g. From the results of serological inspection, metabolism in body was normal with all the browses tested. Dressing percentage was 45.1~46.2% and meat percentage was 55.2~55.9% without significant differences between diets. Fat percentage of goat carcasses fed rice straw was higher than those fed pine browse or fermented pine browse which was, however, not significantly different from those on oak browse. Shear force and coking loss of goat meat on pine browse or fermented pine browse was less than those on rice straw(p〈0.05) without significant differences between other browses. Juiciness, tenderness, and flavor of the goat meat were the better(p<0.05) from the pine browse diet than from rice straw.

  • Cellulose-digesting bacteria were isolated from hindgut of Allomyrina dichotoma (Coleoptera: Dynastidae). The bacterial isolates were identified as Yersinia sp. and Bacillus sp. The addition of the identified bacteria to diet increased growth rate of the cetoniid beetle, Protaetia brevitarsis senlensis (Coleoptera: Cetoniidae), probably by digesting cellulose nutrient contained in the oak tree sawdust diet. An additive of wheat flour at more than 10% to the sawdust diet significantly enhanced growth of P. brevitarsis senlensis. Trimmed branches of apple trees have been disposed in the apple farms and could be used for a diet component of the cetoniid beetle when the cellulose-digesting bacteria were mixed with the derived-sawdust. Resulting manure from mass rearing of P. brevitarsis senlensis contained high organic matters and trace amounts of toxic metals. When the manure were splayed on soil, it was effective as a natural compost and significantly stimulated lettuce growth. This research suggests a model technology to use cellulose-digesting bacteria to use for culturing grub, which results in natural recycles of trimmed branches in apple farms as grub diet, and to use grub manure as a natural compost.

  • A total of 150,624 records of Holstein milk production collected from 2005 to 2009 were analyzed to investigate the effects of two different contemporary group definitions, parity and somatic cell score (SCS). The first definition (H BY S) of contemporary group was milking cows and heifers born in the same year and season. And the second thing (H CY S) was milking cow and heifers that delivered calves in the same year and season. Effects of contemporary group, parity and regression effect on SCS from two models were highly significant sources of variation. Coverage of variation ($R^2$) was somewhat higher in models with H BY S as contemporary group. From multivariate models with H BY S, phenotypic correlation coefficients of milk components were estimated high and positive. However, the phenotypic correlation coefficient between milk yield and SCS was -0.09, which was low enough to evidence no correlation between them. Phenotypic correlation between SCS and butter fat or between SCS and protein were also negligible but negative. From multivariate models with H CY S as contemporary group, phenotypic correlation among milk traits and SCS were similar to the estimates from models with H BY S. However, SCS in these models were lowly but negatively correlated with milk yield, milk protein, butter fat or SNF, and the phenotypic correlation coefficients of which were -0.10, -0.08, -0.08, -0.11, respectively.

  • The white-spotted flower chafer (Protaetia brevitarsis) larva is one of the insects widely-used for edible and medicinal purposes in Eastern Asia. As a result of increasing demand for P. brevitarsis, massrearing systems in domestic farms have become necessary. However, the mass-rearing of larvae under confined rearing conditions could provide conditions unsuitable for preventing entomopathogenic diseases. Metarhizium anisopliae is the strongest fatal entomopathogenic fungus against P. brevitarsis. For inhibition of M. anisopliae, we used a Rhus verniciflua Stokes extract that has antifungal components. We investigated the inhibitory effect of the R. verniciflua extract at 1%, 5%, and 10% concentrations. The results showed that a 1% R. verniciflua extract added to sawdust produced a significantly low P. brevitarsis mortality rate. Moreover, extract-treated groups were heavier and had a shorter larval period than those of the untreated group. Consequently, we suggest that using an R. verniciflua extract can reduce the P. brevitarsis fatality rate from entomopathogenic fungi (e.g. M. anisopliae), resulting in more effective mass-rearing systems for P. brevitarsis.
