Tarsal tunnel syndrome is a complex of symptoms resulting from the compression of the posterior tibial nerve or its branches, Many disease have been previously reported in the literatures as etiological agents in tarsal tunnel syndrome. We reported a case of tarsal tunnel syndrome secondary to neurilemoma of the first branch of lateral plantar nerve. The symptoms were similar with the entrapment syndrome of the first branch of the lateral plantar nerve. Symptoms were completely relieved after operation.

Large vessel vasculitis is characterized by chronic inflammation within the aortic wall and its major branches. The inflammation is considered to occur as a result of immune dysregulation. Hematologic malignancy is one of the rare causes of secondary vasculitis. Herein, we report a rare case of large vessel vasculitis associated with acute myeloid leukemia mimicking primary vasculitis.

To understand flowering response under diverse day-length condition and the movement of floral stimulus, we used six perilla accessions which showed diverse days to flowering. Though the growth phase was reported as irreversible between vegetative and reproductive stage, perilla showed reversible growth phase according to day length increase in May and June. When it sowed in March, flowering response was started in early May and vegetative and reproductive phase was coexisted in late June. When a part of a perilla plant was treated under short day condition, only apical buds on main stem or branches were flowered but other long day conditioned apical buds were not flowered. With this result it is suggested that the floral stimulus can not be transferred to other part of perilla.

This experiment was carried out to understand the effect of pre-sowing seed treatment by GA$_3$ and IAA on flowering and characteristics of yield component in peanuts. Peanut seed was treated by soaking in 10, 50, 100ppm of GA$_3$ solution, and 50, 100, 200ppm of IAA solution. Treatments of GA$_3$ and IAA resulted 7-5 days earlier emergence and 11-17days shorter of the flowering date compared with the untreated control. By soaking treatments with IAA in 100ppm and GA$_3$ in 100ppm, accumulated flowers were increased at early growing stage of 30 days after flowering compared with untreated control. By soaking treatments with IAA in 100ppm and GA$_3$ in 100ppm, main stem length, branch length and internode of main stem showed to flourish at investigation from early growing stage to 3 days before harvesting.

Pebble-bearing clastic carbonate rock which has been found in and around the Jeongseon and Okgye through the field survey was studied in petrological and mineralogical characteristics. We define the clastic carbonate rocks as 'Dolomite-pebble bearing fine sand-sized dolostone, or grainstone', which are characterized by the existence of dolomite single grains and Mg-phengite, and by the subsequent formation of secondary calcite cements. These attributes correspond well with those of the typical Haengmae Formation from Haengmae-dong, Mitan-myeon, Jeongseon-gun, thus the carbonate rocks in the Jeongseon and Okgye areas must belong to the Haengmae Formation. The result suggests that the Haengmae Formation is an independent unit among the Paleozoic lithostratigraphic units in Taebaek basin and lies in the upper part of Jeongseon and Sukbyungsan Formations under the Hongjeom Formation of Pyeongan Supergroup.

This study was carried out to investigate the lodging patterns and the direct and indirect effects of several agronomic characters upon lodging of soybean plants. Most of the lodged plants had bent main stem above first stem node at higher plant density. Lodging was significantly correlated with plant height, internode length and shoot fresh weight in two soybean cultivars, Paldalkong and Jangyeobkong. Root fresh weight was also significantly correlated with lodging in Paldalkong, Jangyeobkong and Kwangkyo. Length of internode showed the greatest direct effect on lodging in Paldalkong and Jangyeobkong.

This experiment was conducted to obtain some informations on the effects of number of leaf harvest and time to agronomic characters and grain yield in perilla. For the experiments perilla seedlings of 40days old were transplanted on June 20, July 20 and August 20 in 1988, and leaf harvested at 30. 40. 50 and 60 days after transplanting, respectively. The following results were obtained from the experiments. In the case of the fully developed leaves were harvested, culm length were decreased by more harvests and by the later harvests. However culm diameter, number of nodes and branches were little influenced by the leaf harvests. Number of clusters, weight of 1,000 grain and grain yield were significantly influenced by the number of leaf harvest and time. As the above results, considering the grain yield, leaf harvest would be available in the case of once or twice at the early growing stage.

We have studied general orientational characteristics of microcracks distributed in Tertiary crystalline tuff from the northeastern part of the Gyeongsang Basin. 108 sets of microcracks on horizontal surfaces of 6 rock samples from Heunghae-eup and Cheongha-myeon, Pohang-si areas were distinguished by image processing. Those microcrack sets show a distinct linear array in 38 images. Whole domain of the directional angle(${\theta}$)-frequency(N) chart for crystalline tuff can be divided into 20 domains in terms of the phases of the distribution of microcracks. From the related chart, microcrack sets show preferred orientation which are coincident with the direction of vertical common joints. Consequently, the potential for macroscopic vertical joints in a rock body can be inferred from the directional angle showing high frequency in each domain of the related chart. This joint pattern is nearly the same in Mesozoic granites from Seokmo-do, Gwanghwa-gun. From the rose diagram for orientations of microcrack in crystalline tuff, orientations of dominant sets of microcracks in terms of frequency orders reflect representative orientations of maximum principal stress acted on crystalline tuff. Meanwhile, orientations of microcracks in crystalline tuff were compared with those of open microcracks in Bulgugsa granites from the southwestern part of the Gyeongsang Basin, and vertical rift/grain planes from Mesozoic granite quarries in Korea. In regional distribution chart, the agreement of distribution pattern between above two types of microcrack sets and vertical planes suggests that microcrack systems developed in crystalline tuff probably occur regionally in Mesozoic granites in Korea.

This experiment was carried out in the field to investigate the effects of sowing date and planting density under non - or P. E. - mulching cultivation on growth and yield of safflower. The optimum sowing date for safflower in the central and northern area of Korea was March 20th directly after thawing of frozen soil. P. E. - mulching cultivation was profitable with increasing the kernel yield 20% higher than in non­mulching cultivation. With respect to the the planting density, non - mulching $50[{\times}10cm$(20.000plants per10are) and P. E. - mulching $50{\times}15cm$(13,330 plants per 10 are) were optimum respectively.

This study was carried out to obtain the basic information on mating parents and selection for high yielding safflower breeding. Thirty nine world safflower lines, which had collected from 13 countries of origjn, were evaluated for major agronomic characters, correlation and path-coefficients. The results obtained were summarized as follows. Days to flowers ranged from 83 days to 100 days. Days to flower of most foreign lines were later than that of domestic lines. Plant height ranged from 75 cm to 162 cm. The plant height and stem diameter of most foreign lines were higher than those of domestic lines. The leaf number and size of domestic lines were much more than those of foreign lines. The total branch numbers of foreign lines were more than domestic lines. Particularly, the number of third branch ranged from 0 to 25 and there were none in domestic lines. The number of corolla of foreign lines was much more than that of domestic lines. The yield of foreign lines collected from Central Asia and United States of America were more than any others. Significantly positive correlations were observed between yield and days to flower, stem diameter, the number of branch and the number of corolla. In the analysis of path-coefficient, the highest direct effects on yield was the number of corolla followed by the number of total branch, whereas those of the number of second branch and stem diameter were negative.
