Background: Nail can be affected by trauma, infection, and systematic disorders. In particular, the toe nails are exposed to the repeated and cumulative minor traumas, which usually result in thickened, splitted, and discolorated nails. Considering these, it can be inferred that the long second toe can be related to various nail and skin changes by repeated minor traumas such as friction in shoes, but the study or report on this topic hasn’t been done yet. Objectives: The purpose of this study was to introduce various nail and skin changes on long second toe. Methods: We analyzed the kinds of nail/skin changes of 50 patients with long second toe, enrolled at Pusan National University Hospitals (Busan and Yangsan) from 2013 to 2018. Results: There was no significant difference in the incidence of left and right toe and toenail, and 7 (14%) patients presented bilateral distribution. The most common nail change on long second toe was melanonychia (23, 46%), followed by subungual hematoma (15, 30%), onycholysis (2, 4%), subungual hyperkeratosis (2, 4%), onychomadesis (1, 2%), and retronychia (1, 2%). The most common skin change was corn (9, 18%), followed by paronychia (2, 4%). Twenty (20/50, 40%) patients also had other toe or toenail changes. Among them, the most common site was big toe/nail (13, 62%), and the most common change was subungual hematoma (8, 42%). Conclusion: Through this study, the dermatologists can recognize and diagnose the nail and skin changes of long second toe.

Rock Magnetic Approaches Used on Deep-sea Sediments in the Northeastern Equatorial Pacific

Park, Cheong Kee,Lee, Gun Chang The Korean Society of Oceanography 2018 OCEAN SCIENCE JOURNAL Vol.53 No.2

Rock magnetic properties of unconsolidated sediments from the Korea Deep Ocean Study area of the northeastern equatorial Pacific were analyzed to trace the time-dependent variations of sedimentary environments. For upper Pleistocene sediments, light-brown sediments predominate, whereas the lower sediments deposited in the late Pliocene are dark brown. Rock magnetic properties also clearly differ among the two distinct color environments. Values of anhysteretic remanent magnetization and low-field magnetic susceptibility are highly responsive to changes in the color of the sediment. For example, comparatively low values denote a dominance of coarse-grained magnetic minerals as observed in the lower dark-brown layers. With respect to the content of magnetic minerals, coarse magnetic grains are highly concentrated in the darker-colored sediment layers. However, both the magnetic mineral dependent parameter (S ratio) and results of the scanning electron microscope observation indicate that magnetic mineral changes did not occur along the core depth, which means that there was no apparent source change. Without distinctive source changes, the variations in the rock magnetic properties likely reflect a process by which the magnetic grains were primarily transported by enhanced wind and bottom currents and affected by diagenetic dissolution as a function of both the time from burial and the extremely low sedimentation rates after deposition.

연구논문 3 : 개방과 보호의 기로에 선 한일 농업정책 -제도화된 지역협동을 향한 통상규범의 모색

본 연구는 개방과 보호의 기로에 선 한일 양국의 농업정책이 어떻게 전개되고 있는지를 분석하는 것이다. 논의의 초점은 협업과 분업을 통해 한일 양국의 공동 농업정책이 가능한지를 검토하고, 제도화된 지역협동이란 통상규범이 동북아 3국의 공동 농업정책으로 확산될 수 있는지를 살펴보는 것이다. 한일 양국의 농업정책은 경제 성장에 의한 산업화 과정에서 이루어졌고, 국제정치경제 변화에 편승하여 보호와 개방이란 정치적 선택에 따라 유연성 있게 대처하고 있다. 하지만 신자유주의적 세계화가 농업 시장의 개방을 다방면에서 요구하고 있기 때문에 한일 양국은 공동 대응 방안을 절실히 필요로 하고 있다. 공동 대응을 위한 제도적 장치 마련의 근간은 이미 양국 농업정책에 융합되어 있어 지역협동을 향한통상규범에서 엿볼 수 있을 것이다. 이러한 의미에서 본 연구는 통상규범의 수단으로 협업과 분업에 대한 논의를 제시하고 있다. 협업을 통한 공동 농업정책의가능성은 제도화된 지역협동이란 통상규범의 기틀이 정착되어 있는 것처럼 보이 지만, 농업의 특성상 이를 응용하고 활용하려는 정치적 논의가 미흡한 것으로 나타났다. 반면 분업을 통한 공동 농업정책의 가능성은 농업이 공업과 달리 수평적혹은 수직적 분업이 구조적으로 어려운 경우가 존재하기 때문에 제한적 범위 내에서 실현할 수 있다는 결론을 도출하고 있다. 한일 FTA 체결의 주요 쟁점이 농업이라는 점을 고려한다면, 양국이 협업과 분업을 통한 공동 농업정책 가능성을 현실적으로 모색하기 위해서는 그 규모와 범위에 대해 기능적으로 접근해야 할것이다. 즉, 한일 양국은 중국을 포함한 동북아 3국이 하나의 지역협동체가 되어 공동 농업정책을 이끌어 낼 수 있는 제도적 대안을 마련해야 한다는 것이다. This research analyzes how agricultural policies in Korea and Japan, which are at the crossroad of liberalization and protection, are being developed. The focus of the discussion reviews whether the two countries can carry on the common agricultural policies through cooperation and specialization and examines commercial norms, namely institutionalized regional collaboration could expand into three countries in Northeast Asia. Agricultural issues between the two countries of Korea and Japan are formed by economic growth in the process of industrialization and liberalization and protection are dealt flexibly depending on political choices piggybacking on the international political and economic changes. However, both Korea and Japan jointly require to have new countermeasures urgently because neo-liberal globalization is requiring the opening of agricultural market in many areas. The foundation of established institutional mechanisms for joint countermeasures, that is already melted in agricultural policies in Korea and Japan, could glimpse of commercial norms towards regional cooperation. In this sense, this research suggests argument about cooperation and specialization as a means of commercial norms. The possibility of common agricultural policies as cooperation seems to be settled the framework of commercial institutionalized regional collaboration but political debate applying and utilizing it showed insufficient in the nature of agriculture. It comes to conclusion that the possibility of common agricultural policies as specialization will be realized within limited range because implement of horizontal or vertical specialization is structurally difficult for agriculture unlike industry. Considering agriculture is the main issues of Korea and Japan FTA, the two countries should approach functionally the scale and scope in order to seek realistically the possibility of common agricultural policies as cooperation and specialization. In other words, three countries in Northeast Asia(Korea, Japan and China) will have to arrange institutional alternatives which can lead to joint agricultural policies as one of regional cooperative body.

( Geun-hwi Park ),( Woo-il Kim ),( Min-young Yang ),( Won-ku Lee ),( Tae-wook Kim ),( Sung-min Park ),( Hyun-joo Lee ),( Gun-wook Kim ),( Hoon-soo Kim ),( Hyun-chang Ko ),( Byung-soo Kim ),( Moon-bum 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: Though skin metastasis is rare, it can seriously affect the prognosis and management. The role of dermoscopy in primary skin cancers are established well, but its role in skin metastasis hasn’t been clear. Objectives: This study was performed to elucidate the dermoscopic patterns of metastatic skin cancers. Methods: We analyzed the dermoscopic patterns and clinical data of 46 patients with metastatic skin cancers at Pusan National University Hospitals (Busan and Yangsan) from 2005 to 2018. Results: Mean age and disease free interval were 62.0±14.2 years and 29.2±41.2 months, respectively. The most common primary origin of cancer was breast (11/46, 23.9%), followed by lung (8/46, 17.4%), and upper gastrointestinal tract (8/46, 17.4%). Any dermoscopic patterns was not found in 8 cases, who showed subcutaneous nodules without surface change. Most common dermoscopic pattern was vascular pattern (30/46, 65.2%), followed by homogenous structureless pattern (16/46, 34.8%). Most common vascular pattern was serpentine and arborizing vessel (23/46, 50%), followed by dotted vessel (7/46, 15.2%). There was no significant difference in dermoscopic vascular pattern among cancers, because the number of subjects was insufficient. Conclusion: Based on our study, when vascular patterns such as serpentine and arborizing vessel or dotted vessel are seen on dermoscopy within a nodule in a patient already diagnosed with cancer, metastatic skin cancer should be strongly considered.

Prevention of Adjacent Segmental Disease after Fusion in Degenerative Spinal Disorder: Correlation between Segmental Lumbar Lordosis Ratio and Pelvic Incidence–Lumbar Lordosis Mismatch for a Minimum 5-Year Follow-up

Whoan Jeang Kim,Chang Hyun Ma,Sang Ha Kim,Yeon Seung Min,Jae Won Lee,Shann Haw Chang,Kyung Hoon Park,Kun Young Park,Dae Gun Song,Won Sik Choy 대한척추외과학회 2019 Asian Spine Journal Vol.13 No.4

Study Design: Retrospective study. Purpose: Associations among risk factors related to adjacent segmental disease (ASD) remain unclear. We evaluated the risk factors and segmental lordosis ratio to prevent ASD developing after lumbar spinal fusion. Overview of Literature: Risk factors related to ASD development are age, sex, obesity, pre-existing degeneration, number of fusion segments, and decreased postoperative lumbar lordosis (LL). However, the associations among these factors are still unclear and should be clearly identified. Methods: We retrospectively reviewed data on 274 patients who underwent lumbar spinal fusion of three segments or below for lumbar degenerative disease from January 2010 to December 2012, with over 5 years of follow-up. Patients with preoperative sagittal vertical axis (SVA) >5 cm were excluded due to sagittal imbalance. A total of 37 patients with ASD and 40 control patients (CTRL) were randomly selected in a similar distribution of matching variables: age, sex, and preoperative degenerative changes. Sex, age, number of fusion segments, radiologic measurements, L4–5–S1/L1–S1 LL ratio, and spinopelvic parameters (pelvic incidence [PI], pelvic tilt [PT], sacral slope [SS], and SVA) were analyzed. Logistic regression was used to analyze the correlation between PI–LL mismatch and L4–5–S1 segmental lordosis rate. Results: No significant difference was found between ASDs and CTRL groups regarding age, sex, number of fusion segments, fusion method, and preoperative and postoperative spinopelvic parameters (PI, SS, PT, and LL). However, regarding the L4–5–S1/L1–S1 lordosis ratio, 50% (p=0.045), 60% (p=0.031), 70% (p=0.042), 80% (p=0.023), and 90% (p=0.023) were statistically significant; <20% (p=0.478), 30% (p=0.223), and 40% (p=0.089) were not statistically significant. In the postoperative PI–LL <10 group, ASD occurred less frequently than in the PI–LL >10 group, and the difference was statistically significant (p=0.048). Conclusions: Patients with a postoperative L4–5–S1/L1–S1 lordosis ratio >50% had less occurrence of ASD. Correcting LL according to PI and physiologic segmental lordosis ratio is important in preventing ASD.
