  • Superficial radial neuropathy is a purely sensory neuropathy, usually caused by nerve entrapment in the distal forearm. We report a case of superficial radial neuropathy caused by the anomalous course of the superficial radial nerve, which was found to be spirally encircling the brachioradialis tendon in the distal forearm. To the best of our knowledge, this is the first report of an anatomical variant of the superficial radial nerve that causes neuropathy.

  • Sciatic nerve (SN) is the thickest and longest nerve of the body. Deviations from the normal anatomical origin and level of bifurcation of SN have been frequently reported. In the present case, we are presenting a unique scenario of origin of terminal branches of the SN-tibial nerve (TN) and common peroneal nerve (CPN) in the pelvic region itself from divisions arising directly from the lumbosacral plexus. This variation was associated with origin of posterior femoral cutaneous nerve from the superior division of CPN with anomalous communicating branches between pudendal nerve and TN. The unique characteristics of the present case are the presence of 'pseudoganglion' found on the inferior division of TN. The present case stands out as the first of its kind to mention such pseudoganglion. Knowledge of some unusual findings like presence of pseudoganglion and intercommunications between nerves have clinical implications in anesthesiology, neurology, sports medicine, and surgery.

  • This research aims to figure out the impact of different reflective thinking methods on pre-service geography teachers' teaching knowledge. Four pre-service teachers in the same level were selected through the first simulated instruction, Then, different reflective methods were given them to carry out the reflection. Afterwards, they carried out their second simulated instruction. The change of average score of pre-service teachers was analyzed through the peer reviews and Paired samples T-test. The results are as follows. First, when the first peer review score were compared with second peer review, average score of all pre-service teachers improved. But, pre-service teachers who got cooperative reflection with a specialist had the widest variation in the increase level of average score comparing to those without reflection or reflective journal writing. Second, reflective journal writing through self-reflection led to their reflective thinking, but it did not induce them to reflective practice. Finally, pre-service teacher who got cooperative reflection with experienced teachers got the significant improvement in PCK through the T-test. In particular, it had significant statistical value in instruction section and understanding of students section. It demonstrates that the contextual section could be improved by self-reflection or repetitive class practices, while instruction section and understanding of students section needed consulting by assistants.

  • Objectives: This study was performed to understand pregnancy, delivery, and infant rearing knowledge and educational need of marriage immigrant women to be utilized as a basic data for developing a suitable educational program. Methods: The subject of the study was composed of one hundred twenty two married immigrant women who live in South Korea. The method used in determining the population was the convenience sampling method. The data were gathered by means of personal interviews using questionnaires. Results: The mean score of pregnancy and delivery knowledge was 3.35, educational need was 3.64 out of 5, and infant rearing knowledge was 3.16, educational need was 3.66 out of 5. The pregnancy and delivery knowledge of the subject showed significant differences based on their present residential location and presence of children and their educational need varies according to their country of origin. The infant rearing knowledge on the other hand, showed notable differences according to presence of children while homeland and existence of children were the two major factors that greatly influenced the significant variation for educational need. Conclusions: The score of pregnancy, delivery and infant educational need were higher than knowledge. The score of pregnancy, delivery, and infant rearing educational need garnered similar results. Thus it is suggested that further researches should be conducted for the development, application, and verification of pregnancy, delivery, and infant rearing education programs that consider knowledge and educational need of immigrant married women in South Korea.

  • Daejeon Metropolitan City has the best innovation capability infrastructure (ICT) required for the 4th industry. Nevertheless, there are scattered factors that hinder the industrial ecosystem. In this study, the factor of job creation was approached from the viewpoint of organizational ecology in consideration of regional characteristics during the 4th Industrial Revolution.That is, the case of job creation through overseas ICT-based clusters (or cities) was examined. Then, the factors of organizational ecology, 'niche', 'variation', 'selection', and 'retention' were derived. Through this process, we explored the environment surrounding Daejeon Metropolitan City and benchmarked lessons from existing overseas cluster cases. As a result, we discover the 'niche' of ICT-based job creation and suggest strategies for the 'variation' process to survive in the ecosystem and how to be 'retention' in the ecosystem. n conclusion, the strategy of the organizational ecological approach to establish itself as a metropolitan city as the strength of Daejeon city and the 'innovation hub' that is evident, such as '4th Industrial Revolution City', 'Innovation City Designation', and 'Secure Excellent Capability of SW' Insist on need. Through this study, we hope that there will be a theoretical contribution to the prior research lacking from original research such as the scarcity of ICT-based job creation research in response to the era of the fourth industrial revolution, recognition of the importance of the region in job creation, and presentation of an organizational ecological approach of sustainable clusters.

  • This study has investigated the surface phase change, hardness variation, surface precipitates, nitrogen content and corrosion resistance in STS 431 (17Cr-2Ni-0.2C-0.01Nb) martensitic stainless steel after high temperature gas nitriding (HTGN) treatment at the temperature range between $1050^{\circ}C$ and $1150^{\circ}C$. The HTGN-treated surface layer appeared $Cr_2N$ of rod type, carbo-nitride of round type and fine precipitates in the austenite matrix. On the other hand the interior region where the nitrogen was not permeated, exhibited martensite phase. The surface hardness showed 250~590 HV, depending on the HTGN treatment conditions, while the interior martensitic phase represented 520 HV. The permeation depth of nitrogen increased with increasing the HTGN-treated temperature. The nitrogen concentration of the surface layer appeared approximately ~0.17% at $1100^{\circ}C$. On comparing the corrosion resistance between solution-annealed and HTGN-treated steels, the corrosion resistance of HTGN-treated steel was superior to that of solution-annealed specimens.

  • In this paper, I advocate interactive model which treats science and technology as distinguishable subcultures each with their own bodies of lore and competence against the traditonal hierachical model which treats technology as applied science. For engineering science which is a component in technology as knowledge, I count design as the core part of engineering and discuss the characteristic of engineering design. I also critically assess the models of technological knowledge change, Khunian model and variation-selection model to understand the relation between science and technology. I propose a model that science and technology interaction is mediated interaction. I only outline the plausibility of this model. Industrial research is a modern form of the interaction between science and technology. I discuss Reich who focused on the broad background of industrial research and MeyerThurow who has microperspective in industrial research. The conclusion I draw from the discussion, is that through industiral research, the science-technology interaction become more structured and autonomous, and the scientists and engineers become simply patrs of the structure of industrial research rather than the personal subject.

  • $17{\alpha}$-Ethynylestradiol (EE2) has gotten growing concerns due to its widely detected in the environment and high estrogenic potency. However, the knowledge on the photochemical behaviors of EE2 in natural waters is still limited. Herein, the photodegradation and estrogenic potency variation of EE2 induced by nitrate were studied using a sunlight simulator consisted by a 300 W medium pressure mercury lamp and 290 nm cut-off filters. It was found that EE2 could be photodegraded at a rate of $0.0193h^{-1}$ in pure aqueous solutions, and the photodegradation of EE2 could be significantly promoted by nitrate. The photodegradation removal rate of EE2 was increased from 9% in Milli-Q water to 85% in 2.0 mM nitrate solutions. Reactive species scavenging experiments demonstrated that the photogenerated $HO{\bullet}$ contributed about 55% to EE2 degradation. Fe(III), Cl- and dissolved humic acid (DHA) could inhibit the photodegradation of EE2 by competing the incident light and photogenerated $HO{\bullet}$, while $HCO_3{^-}$ had no influence on EE2 photodegradation. EE2 was determined to be phototransformed into organic chemicals without estrogenic potency by GC-MS and MCF-7 cell proliferation toxicity tests. These findings could extend our knowledge on the photochemical behaviors of steroid estrogens and provide information for ecological risk assessment.

  • The extensive variation in human cutaneous pigmentation is mainly due to differences in the rate of melanin synthesis by epidermal melanocytes, the relative amounts of eumelanin and pheomelanin synthesized, and the manner and rate of transfer of melanosomes from melanocytes to keratinocytes. Pigmentation is a complex trait that is regulated genetically and environmentally. One gene that has been receiving a lot of attention is the gene for the melanocortin 1 receptor The extensive polymorphism of this gene in human populations suggests its significance in the diversity of pigmentation. Exposure to solar ultraviolet radiation (UV) results in increased synthesis of a variety of growth factors, cytokines and hormones, and in modulation of their receptors in the epidermis. Knowledge about the regulation of pigmentation has led to strategies for clinical treatment of hyperpigmented skin lesions. Three main strategies are: 1) the use of chemicals that interfere with the melanin synthetic pathway, 2) the design of peptides or peptide-mimetics based on the structure of hormones that regulate eumelanin synthesis, and 3) the use of agents that reduce melanosome transfer from melanocytes to keratinocytes. All three strategies are expected to induce hypopigmentation, by inhibiting total melanin synthesis, eumelanin production, or the epidermal melanin unit, respectively.
