  • The crystallization behavior of amorphous silicon (a-Si) film was investigated by using Cu-field aided lateral crystallization (Cu-FALC) process below $450^{\circ}C$. The lateral crystallization was induced from the Cu deposited region outside of pattern toward the Cu-free region inside of the pattern by applying an electric field during heat treatment. As expected, the lateral crystallization toward Cu-free region proceeded from negative toward positive electrode side. The occurrence of Cu-FALC phenomenon was interpreted in terms of dominant diffusing species in the reaction between Cu and Si. Even at the annealing temperature of $350^{\circ}C$, the large dendrite-shaped branches were formed in the crystallized region and the polarity in the lateral crystallization was clearly observed. Consequently, we could successfully crystallize the a-Si at the temperature as low as $350^{\circ}C$ by an electric field of 30 V/cm with fast crystallization velocity of 12 $\mu$m/h.

  • The four species of the suborder Holaxonia, Anthogorgia japonica Studer, 1889 of family Acanthogorgiidae, Astrogorgia rubra (Thomson & Henderson, 1906), Euplexaura attenuata (Nutting, 1910), and E. erecta (Kukenthal, 1908) of family Plexauridae have been newly recorded in Korea. They were collected from intertidal and sublittoral zones in the western and southern coasts and Jeju-do Island of Korea by SCUBA diving and fishing nets from 1969 to 2010. This study approaches holaxonians by focusing on external and internal morphologies including size, form, and color of colonies, branches, polyps, coenenchyme, axis, and spicules. Anthogorgia japonica is characterized by its planar growth form, dichotomously branched form, non-retractile polyps, and Astrogorgia rubra by arrangement of calyxes being situated in lateral side at stems and alternately in all sides at branches. Euplexaura attenuata is sparsely and laterally branched colony, and has straight wand-like stems. Euplexaura erecta has branches which run parallel to the main stem.

  • Paravertebral anesthesia for operation of abdominal wall in Korean cattle were effectively accomplished with the following technique. Any problems in surgical procedure were not observed under the block of ventral branches of the last thoracic nerve and the first and second lumbar nerves with the administration of preanesthetic. The site of injection for blocking of ventral branches of the thirteenth thoracic nerve were approximately 5cm lateral to the midline from the posterior edge of spinous process of the 13th thoracic vertebra and about 10ml of local anesthetic was injected immediately anterior to the transverse process of the first lumbar vertebra through thin site. The block of ventral branches of the first and second lumbar nerves were obtained by injecting 10ml of local anesthetic immediately below the posterior edge of transverse process of the 2nd and 4th lumbar vertebra, respectively.

  • The intercostobrachial nerve (ICBN) originates from the second intercostal nerve's lateral cutaneous branch, while the median nerve (MN) typically arises from the brachial plexus's lateral and medial roots. The medial cutaneous nerve of the arm, a branch of the medial cord of the brachial plexus, often connects with the ICBN. Variations were observed during the dissection of a 50-year-old male cadaver, including MN having two lateral roots (LR), LR1 and LR2, joining at different levels. Three ICBNs innervated the arm in this case, with the absence of the medial cutaneous nerve of the arm compensated by branches from the medial cutaneous nerve of the forearm. Understanding these anatomical variations is crucial for surgical procedures like brachioplasty, breast augmentation, axillary lymph node dissection, and orthopedic surgery. Surgeons and medical professionals must be aware of these variations to enhance preoperative planning, minimize complications, and improve patient outcomes in these procedures.

  • Objectives : Most meridians have each well point located at the distal end of fingers or toes, congruous with their meridian courses. Exceptively, ST45(Yeotae), stomach meridian(ST)'s final point, is located at the lateral side of the tip of the second toe, while the tip of the second toe was not mentioned in the course of ST. So, we studied the course of lower limb region of ST. Methods : Courses of ST in Categorized Collection of Literatures on Chinese Meridians and Collaterals(CCM) was examined. The literatures included in CCM was selected as study subjects to be studied if the meridian route was different from "Youngchu" or more detailed notes were attached. There are 3 branches in lower limb region of ST, we analyzed theories of scholars of all time about the 3 branches of ST. Results and Conclusions : Branch 1 descends along the lateral margin of the fibula to the dorsum of foot, entering into the medial side of the middle toe. Branch 2 leaves ST36 separately, terminating at the lateral side of the middle toe. Branch 3 leaves ST42 and descends to the end of the great toe. The medial side of the middle toe equate to the lateral side of the second toe, and it is connected to ST45. So branch 1 is the main stream of ST. Branch 3 drives to the great toe passing between first and second toe, it goes medial side of LR2.

  • In recent years, the development of application programs for distribution system analysis and control has been essential part for distribution management system (DMS). In this paper, we propose the common database for application programs of distribution management system. The proposed database model has several characteristics as followings. First, the proposed database model is designed for the common use of almost the whole distribution application software. The static equipment model and dynamic type tables are mixed and the parallel table structure is applied. Second, the linked list structure of database are used for the fast processing of applications. The database model includes the hierarchy and non-hierarchy distribution system structure. Third, the reduction method of distribution database is applied. For this, we present the network reduction rules. The basic concept of reduction rules are the electrical unification of successive line section which has not lateral branches and the removal of simple lateral branches which has no devices and other laterals. Proposed database model is tested for the Jeju system of Korea Electric Power Corporation (KEPCO). Through the test, we verified that the proposed database structure can be effectively used to accomplish the distribution system operation.

  • The fruiting habit pattern of white-spine cucumber, whose fruits are usually borne on the lateral branches, is different from domestic ones. The cucumber production far export has been focused on how to promote lateral shooting and how to increase the number of lateral branches. As the growing season of the exporting cucumber is confined to winter season, low temperature and weak light are limiting factors to lateral shooting. This study was conducted to investigate the effect of foliar application of growth regulator for induction of lateral shoot in white-spine cucumber. foliar application of growth regulator were focused on concentration and application time based on number of leaves. The visible damages were observed in applied leaves by $30mg{\cdot}L^{-1}$ BA(benzyladenine) in retarding culture, but no significant by $10mg{\cdot}L^{-1}$ BA in case of semi-forcing culture. The number of available lateral shoots were greater in applied plant with $10mg{\cdot}L^{-1}$ BA than that of $30mg{\cdot}L^{-1}$ BA, in applied plants at 10th and 15th loaves than that of applied plants at 5th leaves.

  • Altered dendritic morphology is frequently observed in various neurological disorders including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), but the cellular and molecular basis underlying these pathogenic dendritic abnormalities remains largely unclear. In this study, we investigated dendritic morphological defects caused by dipeptide repeat protein (DPR) toxicity associated with G4C2 expansion mutation of C9orf72 (the leading genetic cause of ALS and FTD) in Drosophila neurons and characterized the underlying pathogenic mechanisms. Among the five DPRs produced by repeat-associated non-ATG translation of G4C2 repeats, we found that arginine-rich DPRs (PR and GR) led to the most significant reduction in dendritic branches and plasma membrane (PM) supply in Class IV dendritic arborization (C4 da) neurons. Furthermore, expression of PR and GR reduced the number of Golgi outposts (GOPs) in dendrites. In Drosophila brains, expression of PR, but not GR, led to a significant reduction in the mRNA level of CrebA, a transcription factor regulating the formation of GOPs. Overexpressing CrebA in PR-expressing C4 da neurons mitigated PM supply defects and restored the number of GOPs, but the number of dendritic branches remained unchanged, suggesting that other molecules besides CrebA may be involved in dendritic branching. Taken together, our results provide valuable insight into the understanding of dendritic pathology associated with C9-ALS/FTD.

  • The instep flap and medialis pedis flap are both originate based on the medial plantar artery. The medialis pedis flap is based from the deep branch and the instep flap is based from the superficial branch. To increase the axial rotation, it is acceptable to ligate the lateral plantar artery. However, this can partially affect the blood supply of the plantar metatarsal arch. We restored the blood flow with a vein graft between the posterior tibial artery and the ligated stump. From 2012 to 2020, 12 cases of heel reconstruction, including seven instep flaps and five medialis pedis flaps, were performed with ligation of the lateral plantar artery. The stump of the lateral plantar artery was restored with a vein graft and between the posterior tibial artery and the ligated stump. Patients were followed for 18 months. Long-term results showed the vascular restoration of the lateral plantar artery remained patent demonstrated by doppler ultrasonography. Restoring blood flow to the lateral plantar artery maintains good blood supply to the toes. If the patient in the future develops a chronic degenerative disease, with microvascular complications, bypass surgery can still be performed because of the patency of both branches.
