  • Orogenic cycle is closely related with sedimentary cycle, and a sedimentary cycle involves the birth, development and disappearance of a sedimentary basin. Paleontological studies have indicated that birth or disappearance of sedimentary basins of separated regions frequently coincided in time. In this paper, the writer presents his assumption on the East Asian analogy of the Hercynian orogenic cycle in accord to the above mentioned generalities. Previous studies, including mine have a corollary that Korea and Southern China, which had been uplifted by the Caledonian movement, changed into low-lying region with subsiding areas in the Givetian time. The writer, thus, thinks that the Hercynian orogenic cycle started in Givetian, and that the Mongolian geosyncline in China, the Gangweon Basin in Korea and the Honshu geosyncline in Japan disappeared in the Ladinian. The writer, therefore, thinks that the Ladinian marks the end of the Hercynian orogenic cycle, but this assumption will have to be rechecked in consideration with the Alpine orogenic cycle. The Late Namurian-Early Bashkirian time, the dividing period between the early and late Hercynian orogenic cycle, is thought to correspond the time of the Hongjeom Series deposition. The writer is also of the view that the Akiyoshi orogenic cycle(T. Kobayashi) corresponds the late Hercynian phase, and that the Abenian movements(M. Minato) corresponds to the range from the late Caledonian phase to the former part of late Hercynian phase.

  • Although the success rate of deep inferior epigastric perforator (DIEP) flaps has increased, late flap failures still occur and have a low salvage rate. The present article describes a case of salvage of a case of late flap failure using the pedicle vein as a vein graft source. A 50-yearold woman underwent a bilateral DIEP free flap procedure. On postoperative day 6, she experienced flap compromise and underwent emergency flap revision. In the flap revision, flap venous drainage and the superficial inferior epigastric vein were completely obstructed. A Fogarty catheter was used to remove a thrombus from the completely obstructed pedicle vein, and this pedicle vein was used as a graft source and was ligated in retrograde fashion to the flap vein stump. After injection of urokinase into the arterial branch, venous flow to the flap was restored. At a 6-month follow-up visit in the outpatient clinic, only partial fat necrosis at the flap was noted. By dissecting various perforators in the initial operation, decisions regarding immediate revision can be made with more confidence. Additionally, the combined procedures performed in this case may be helpful even for practitioners treating cases of late flap compromise.

  • Radiation-induced late injury to normal tissue is a primary area of radiation biology research. The present study was undertaken to investigate whether the late effect of the ionizing radiation appears as an age-related oxidative status in the brain. Three groups of 4-month old C57BL/6 mice that were exposed to $^{137}Cs$ ${\gamma}-rays$ at a single dose (5 Gy) or fractionated doses ($1Gy{\times}5times$, or $0.2Gy{\times}25times$) at 2 months old were investigated for the oxidative status of their brains with both young (2-month) and old (24-month) mice. A significant (p<0.05) decrease in superoxide dismutase (SOD) activity was observed in old mice brains compared with that of the young mice. malondialdehyde (MDA) content was significantly (p<0.05) increased in the old mice brain. However, any significant difference in SOD activity and MDA contents of the irradiated brain was not observed compared to age-matched control group mice. SOD activity and MDA content were observed within good parameters of brain aging and there were no late effects on the age-related oxidative level in the ${\gamma}-ray$ irradiated mice brains.

  • Purpose: Various intervention strategies are needed to reduce the suicide rate among late adolescents. Therefore, we aimed to investigate the factors that can help overcome suicidal tendencies in late adolescents from the perspective of case managers. Methods: This qualitative study explored the reinforcing factors that can help overcome suicidal behaviors in late adolescents, by conducting focus group interviews with case managers from the local community. Interviews with 10 case managers were recorded and transcribed, and the data were analyzed using the content analysis method. Results: The main theme of this study was "a step in a new direction". Three categories were derived: "inner changes", "another possibility opened up by the interest of significant others", and "connecting with community resources to help overcome". Each category had subcategories that influenced the intention and course of action of behaviors to overcome the suicide crises. Conclusion: Our findings, from the exploration of the experiences of case managers, provide an in-depth understanding of the reinforcing factors for overcoming suicide among late adolescents. They provide useful preliminary data for the development of effective suicide prevention programs for the adolescents.

  • This study examined the perception of the royal family and scholars, focusing on the records of the royal family and literary collections in the late Joseon Dynasty, and attempted to present the process of accepting this content in Korea through domestic and foreign medical documents and other literature. The perception of this content in the late Joseon Dynasty can be said to be a characteristic to the history of acupuncture and moxibustion in the Joseon period. This seems to have occurred after the middle of the Joseon Dynasty, when both acupuncture and medicine were commonly performed on the king. This content was generally recognized by Joseon's scholars because it had been in books read by the scholars before it was mentioned directly in the medical book. Korean medical books were influenced by Uihakyimmun, and this content continued steadily in various medical books. Since the books containing this content were test subjects for the medical exam, it can be assumed that they were generally accepted by doctors in the late Joseon Dynasty.

  • This study aims to examine the cutting traces remaining on the bracket tie beams of Sungnyemun gate, identifying the tools employed during the late Goryeo to early Joseon periods by specific processes, and deliberating on the timber shaping techniques utilized in advanced architectural construction during the late Goryeo to early Joseon eras. Through the research, it was confirmed that in the production of Sungnyemun Gate's bracket tie beams during the 14th to 15th centuries, both the timber splitting and ripsawing methods were used in conjunction. Moreover, the wood finishing process revealed the use of a plane. It can be inferred that the characteristics of the plane used during that time were not significantly different from those observed in the later period of the Joseon dynasty. The ripsawing and plane finishing techniques were evident in various parts of the bracket tie beams of Sungnyemun gate across the reigns of king Taejo and Sejong, indicating that the techniques involving ripsaw and plane were already prevalent in the late Goryeo period. Consequently, it can be inferred that the ripsawing and plane finishing techniques might have been applied in the construction of prominent government buildings in Hanyang(Seoul), including Gyeongbokgung Palace, and in the residences of royalty and nobility after the establishment of the Joseon dynasty.

  • This study explored the effect of increased feed intake during the late gestation on the reproductive performance of sows, and fecal score in sows and piglets. A total of 21 crossbred [Landrace × Yorkshire] multiparous sows were randomly distributed into three treatments with seven replicates per treatment. Treatments: CON, 2.4 kg/day; TRT1, 3.2 kg/day; TRT2 , 3.6 kg/day. Body weight and body condition score of sow in different stages were not altered (p > 0.05) due to extra feed in late gestation. A linearly higher (p < 0.05) difference in backfat thickness during farrowing was found in this study. Average daily feed intake was increased (p < 0.05) linearly with extra feed in this experiment. The weaning body weight of piglets was increased (p < 0.05) with extra feed in the sow. The fecal score of sows and their piglets was similar (p > 0.05) in different levels of feed intake. In conclusion, extra feed to gestation sow showed a beneficial effect on improving the weaning piglet's body weight. Although there is a small improvement in the body weight of weaning pigs of sow fed 3.6 kg feed/day in the late gestation period, it is unlikely to be profitable enough to justify the additional waste of feed.

  • Esophagopleural fistula is a rare complication that should be suspected in all patients with recurrent empyema following pneumonectomy and in whom a bronchopleural fistula can be excluded. In late postpneumonectomy esophagopleural fistula, diagnosis is difficult due to its rarity and no specific symptom and sign, but we have experienced a man who had suffered dysphagia and odynophagia. In surgical treatment of late postpneumonectomy esophageal fistula, closure of empyema space is of prime importance. We have adopted a type of latissimus dorsi muscle and serratus anterior muscle flap transposition We present here this technique and result obtained in patient with late postpneumonectomy esophagopleural fistula.

  • The author reports a 32 years old female patient with late luteal phase dysphoric disorder who received evening bright light treatment for 7 consecutive days during the late luteal phase of menstrual cycle. After the treatment, beneficial clinical effects were observed. This result suggests that bright light can be an alternative treatment for LLPDD. However, the placebo effects should be ruled out completely. Further controlled studies with more patients will be needed.

  • Advances in research and medical and supportive care have contributed to a growing population of adults formerly treated for childhood cancer. History of cancer and its therapy can have significant life-long health implications. Late effects of cancer therapy can be insidious on onset, occur outside the pediatric age, and contribute to premature morbidity and mortality. In this review, I have focused on the key long-term effects of pediatric cancer therapy, particularly on the metabolic syndrome, including cardiopulmonary complications, infertility, and secondary neoplasm.
