Facial feminization surgery (FFS) incorporates aesthetic and craniofacial surgical principles and techniques to feminize masculine facial features and facilitate gender transitioning. A detailed understanding of the defining male and female facial characteristics is essential for success. In this first part of a two-part series, we discuss key aspects of the general preoperative consultation that should be considered when evaluating the prospective facial feminization patient. Assessment of the forehead, orbits, hairline, eyebrows, eyes, and nose and the associated procedures, including scalp advancement, supraorbital rim reduction, setback of the anterior table of the frontal sinus, rhinoplasty, and soft tissue modifications of the upper and midface are discussed. In the second part of this series, bony manipulation of the midface, mandible, and chin, as well as soft tissue modification of the nasolabial complex and chondrolaryngoplasty are discussed. Finally, a review of the literature on patient-reported outcomes in this population following FFS is provided.

Seonhwa Bongsa Goryeodogyeong written by Seogeung of Song nationality is the most vivid record of sailing in the West Sea of Goryeo. Seogeung who visited Goryeo on a ship sailed from Heuksando to Byeokrando using a fire signal of the islands area. Fire signal was installed in the Goryeo area, was located nearby the sea route at that time, and was marked by smoke during the day and torched at night so that the navigators could identify it 24 hours. In addition, it was installed at the top of the mountain so that the navigators could easily identify it from a distance. Goryeo fire signal is satisfied by qualification of modern aids to navigation and Visual range is checked about 29-39 miles, Luminous intensity of fire signal estimates to approximately 9,105-168,610cd. Therefore, the fire signal of Goryeo was very easy to use and was highly reliable as operated by the nation and its role in aiding navigations facility as an essential for safe navigation.

The position of existing patrol ships has been decided according to subjective judgments, not purely by any reasonable or scientific criteria, because of a lack of access to marine accident positions. In this study, the optimal location of patrol ships is quantitatively determined based on historical marine accident data. The study area used included the coastal sea of Pohang in South Korea. In this study, a k-means clustering algorithm was used to derive the location of patrol ships, and then a Voronoi diagram was used to divide the region around each patrol ship. As a result, the average navigation distance for patrol ships was improved by 4.4 nautical miles, and the average arrival time was improved by 13.2 minutes per marine accident. Moreover, if the locations of patrol ships need to be changed flexibly, it will be possible to optimally arrange limited resources using the technique developed in this study to ensure a fast rescue.

Recently a traffic accident of heavy duty vehicles under the mandatory installation of ADAS (Advanced Driver Assistance System) is often reported in the media. Heavy duty vehicle accidents are normally occurring a high number of passenger's injury. According to report of Insurance Institute for Highway Safety, FCW (Forward Collision Warning) and AEB (Automatic Emergency Braking) were associated with a statistically significant 12% reduction in the rate of police-reportable crashes per vehicle miles traveled, and a significant 41% reduction in the rear-end crash rate of large trucks. Also many countries around the world, including Korea, are studying the effects of ADAS installation on accident reduction. Traffic accident statistics of passenger vehicle for business purpose in TMACS (Traffic safety information Management Complex System in Korea) tends to remarkably reduce the number of deaths due to the accident (2017(211), 2018(170), 2019(139)), but the number of traffic accidents (2017(8,939), 2018(9,181), 2019(10,095)) increases. In this paper, it is introduced a traffic accident case that could lead to high injury traffic accidents by being equipped with AEB in a bus. AEB reduces accidents and damage in general but malfunction of AEB could occur severe accident. Therefore, proper education is required to use AEB system, simply instead of focusing on developing and installing AEB to prevent traffic accidents. Traffic accident of AEB equipped vehicle may arise a new dispute between a driver's fault and vehicle defect. It is highly recommended to regulate an advanced event data recorder system.

Objectives: The purpose of this study is to investigate and confirm the main factors of IMAGO relationship therapy(IRT) which influences overcoming a crisis of divorce, the role of the Imago relationship therapist and the changes made by the couple themselves in the process of the therapy. Method: This case study was based on the interviews with a couple who had participated in ten sessions of IRT. The couple who had been in the middle of a divorce lawsuit withdrew their suit after the therapy. The Interviews were conducted twice on the couple. The data from the interviews were analyzed by using constant comparative analysis, open coding method and Miles & Huberman's network display. Results: The findings of the study were as follows. Firstly, the factors influencing overcoming a crisis of divorce included preparation for the Imago dialogue and the structure of the Imago dialogue. Secondly, the role of the therapist was providing safety and confidence, deepening couple's conversations, and building the connectedness of the couple. Thirdly, the changes evident after the therapy included awareness of the influence of the original family, new image formation for each spouse, intimacy restoration and a changed perspective. Conclusions: Based on the findings, the study can contribute to healthy relational progress of married couples in conflict by developing the conditions to effectively apply the IRT. In addition, this study can be used to equip therapists with necessary tools and abilities for the therapy.

Cui Bu (1454~1504 BC), named Yuanyuan, named Jinnan. Served as the deputy manager of the Korean King Chosun Hongwenguan (fifth grade official). In 1487, on the way to Jeju Island to perform official duties, because his father died, he went home from the funeral on the third day of the first lunar month in 1488, but was unfortunately on the way. Encountered a storm, and drifting at sea for nearly half a month, he landed at the "Linhai County Boundary of Taizhou Prefecture, Zhejiang Province, Datang Kingdom" (now Sanmen County). Later, Cui Bu went to Hangzhou by land near Taizhou, where he landed, then via Hangzhou, took a boat along the Beijing-Hangzhou Grand Canal to Beijing, and from Beijing by land through Shanhaiguan, and returned to his country via the Yalu River. Cui Bu stayed in China for four and a half months, 136 days, and traveled nearly 9,000 miles. After returning to China, he wrote the book "Piaohailu" in Chinese. This diary-style book has a total of more than 50,000 characters, covering politics, military, economics, culture, transportation, and local customs in the early years of Hongzhi in the Ming Dynasty. The situation is an important document for studying China's Ming Dynasty coastal defense, political system, justice, canals, cities, topography, and folklore.

National Institute of Fisheries Science conducted a total of 39 sighting surveys for marine mammals over 624 sighting days that covered 20,771 nautical miles in Korean waters during 2011-2020. Marine mammals were detected when 83.9% of the marine environment was less than or equal to three on the Beaufort wind scale. Thirteen species of marine mammals were identified, including two species of pinniped, with a majority of cetacean species. Frequently found species were narrow-ridged finless porpoise, followed by common dolphin, minke whale, Dall's porpoise, and Pacific white-sided dolphin. Narrow-ridged finless porpoises and minke whales were located in and offshore around the Korean peninsula, common and Pacific white-sided dolphins were exclusively found in the East Sea for most seasons. The other marine mammals were spotted in some seas and for limited durations.

In retrospect, the irony of this story began with the first meeting of these co-authors-in of all places, Coimbatore, India, in 2008, at the 12th International Perforator Flap Course. Here the junior author [hereafter "jp"] demonstrated his unparalleled skills in networking, and soon thereafter journeyed some 11,073 km to Allentown, U.S. to peruse the operating room and clinics of the senior author [sic. ggh] in action. Within 2 years jp orchestrated the presentation of the 14th International Perforator Flap Course, so ggh with great anticipation flew only 6,830 miles to reach Seoul, Korea for his first time. But four years more elapsed before ggh returned again to Korea to be a visiting professor, all the while not quite sure why any Korean would want anything from a country doctor who resided in nowheresville Allentown, Pennsylvania. Yet, an extraordinary fact then was to be unveiled, about which ggh was totally ignorant. The pioneer of plastic surgery in Korea, the first Korean to have completed an accredited plastic surgery fellowship, by coincidence had accomplished all this in . . . . . Allentown. The collegial relationship that evolved between these co-authors, who met by chance, indeed had a precedent coincidence! Was this "by chance" alone or predestination? Amazingly, in a way similar, the origin of plastic surgery itself in Korea also had Allentown connections. As a tribute to Lew Jae-duk, this important story must be here told, so let us now retrace his past in Allentown so we can find how the future was to be not so far away.

Directed graphic algorithm was applied to an empirical analysis of traffic occupant fatalities based on a model by Crandall. In this paper, Crandall's data on U.S. traffic fatalities for the period 1947-1981 are focused and extended to include 1982-1993. Based on the 1947-1981 annual data, the directed graph algorithms reveal that occupant traffic deaths are directly caused by income, vehicle miles, and safety devices. Vehicle mileage is caused by income and rural driving. The estimation is conducted using three stage least squares regression. Those results show a difference between the traditional regression methodology and causal graphical analysis. It is also found that forecasts from the directed graph based model outperform forecasts from the regression-based models, in terms of mean squared forecasts error. Furthermore, it is demonstrates that there exists some latent variables between all explanatory variables and occupant deaths.

Objective: To investigate the efficacy of gadobenate dimeglumine (GdBOPTA) enhanced MR imaging for the detection of liver lesions in patients with primary malignant hepatic neoplasms. Materials and Methods: Thirty-one patients with histologically proven primary malignancy of the liver were evaluated before and after administration of GdBOPTA at dose 0.05 or 0.10 mmol/kg. T1-weighted spin echo (T1W-SE) and gradient echo (T1W-GRE) images were evaluated for lesion number, location, size and confidence by three off-site independent reviewers and the findings were compared to reference standard imaging (intraoperative ultrasound, computed tomography during arterial portography or lipiodol computed tomography). Results were analyzed for significance using a two-sided McNemar's test. Results: More lesions were identified on Gd-BOPTA enhanced images than on unenhanced images and there was no significant difference in lesion detection between either concentration. The largest benefit was in detection of lesions under 1 cm in size (7 to 21, 9 to 15, 16 to 18 for reviewers A, B, C respectively). In 68% of the patients with more than one lesion, Gd-BOPTA increased the number of lesions detected. Conclusion: Liver MR imaging after Gd-BOPTA increases the detection of liver lesions in patients with primary malignant hepatic neoplasm.
