This study explores PyeongSang, a piece of traditional Korean furniture, in order to make people know the details about what the piece is in the first paper. And based on the paper, PyeongSang will be developed as moulded multi-useful beds and sofas adapting the joint and ornament from the structure and pattern of the piece in the next paper. As the result, it appeared as two styles such as bed types mentioned as SalPyeongSang and ttulmaru in Korean. The pieces have been used from the three Kingdoms period in Korean history. The styles appeared as the structure of four parts with the lower fences called as nangan, the seats jointed by thin wood pieces, the wind hole, and the legs of foot types. The parts were beautifully carved with the ornament such as lattice patterns like geokjamun and manjamun, flower patterns like dangchomun, elephant eyes patterns like ansangmun from the Korean tradition. And the legs showed various shapes such as supports transformed from horse foots, tiger legs and bamboo, and board types carved with elephant eyes and geometric patterns. Hence, in the next paper based on this paper, PyeongSang will be developed as moulded multi-useful beds and sofas adapting the joints and ornaments from the structure and patterns of the piece.

Objectives: The purpose of this study is to collect and analyze the KCD codes applied to the treatment of 27 postpartum women who had been treated with Korean traditional medicine in a Korean medicine hospital, so that this study may be used as a basic data for setting the direction of postpartum Korean medical treatment research. Methods: It was approved by the Institutional Review Board (IRB) of ${\bigcirc}{\bigcirc}$ University medical center (IRB approval number : WSOH IRB H1708-02-01). Twenty-seven postpartum women who had been treated at ${\bigcirc}{\bigcirc}$ University medical center were received outpatient treatment for two weeks (from September 27, 2017 to January 5, 2018), and the KCD codes applied to the mothers were collected after obtaining the consent. On the day of registration of the study, the fertility, obstetric history and high-risk pregnancies were identified through an interview. Results: 1. The mean age of the 27 subjects was $33.33{\pm}3.99\;years$ old. Among the subjects, 17 mothers (63.0%) were high-risk pregnancy and 10 mothers (37.0%) were normal. 2. Among the 22 major disease categories, 8 categories were used. M code (musculoskeletal system) was used 243 times (70.85%), followed by R code (unclassified symptom) of 51 times (14.87%) and U code (special purpose code) of 23 times (6.71%). 3. The most commonly used code among the ten frequently used codes was M25.57 (joint pain, ankle and foot), a total of 47 times. Of the remaining nine codes, except for R60.1 (systemic edema) and U68.4 (The deficiency of yang in Bi), all codes were M codes (musculoskeletal system). 4. The M code (musculoskeletal system) was the most used major disease category in high-risk group, a total of 159 times. But in specific categories, the most commonly used code was R60.1 (systemic edema), a total of 28 times. 5. In normal group, the M code (musculoskeletal system) was the most used major disease category, a total of 84 times. Also, in specific categories, the most commonly used code was M25.57 (joint pain, ankle and foot), total 29 times. 6. The U code, corresponding to 'the diagnosis of childbirth and other obstetrical medical use', was used 23 times (6.71%), O code three times (0.87%) and Z code two times (0.58%), which was less than 10% of the total number of codes used. Conclusion: When analyzing KCD codes related to Korean medicine treatment for postpartum diseases, it is important to select the KCD codes that reflect the actual clinical state.

The purpose of this study is to find out the subjective and objective fatigue level and the characteristics of seamen's physical strength with the service period on board, to have a new understanding of the vocation, and to explore a physical exercising program for the seamen. The questionnaire survey for the seamen who had been in service on the ocean going vessels was conducted and the results are fumed out as the followings. Total number of seamen who had answered the questionnaire was 64 persons and the distribution status of service period group was identified as 16 persons for each of 4 groups； the group was classified as the group of less than 5 years, 5 - 10 years, 10 - 15 years, and more than 15 years. 1. Working conditions Working hours in a week was identified as 44－56 hours(45.3%) and the number of 45.3% of the seamen answered the working hours in week is more than 56 hours. The seamen of 25.0% are unsatisfied or very unsatisfied with their vocation. The seamen of 65.6% are smoking, and 45.3% of them drink. The seamen of 44.,3% drink once or more in a week. And the seamen of 67.2% do not take any exercise in a week. 2. Contribution to the seamen's fatigue and subjective symptom The most contributive factor to the seamen's fatigue was identified as the short of sleeping(21.5%), overwork(19.2%), poor working conditions (18.6%), and the friction in human relations also becomes one the contribution to the fatigue(14.0%). The subjective symptom by fatigue was identified as the feeling of languid, sleepy and tiredness of eyes. 3. Characteristics of the seamen's physical strength and Interrelations The grip strength and back strength of the seamen whose service period is less than 5 years were measured as 40.44kg and 127.8kg. The sit ups in the group of service period less than 5 years was measured as 36.84 times, and the vertical jump for the seamen in this group was measured as 46.55cm. The closed-eyes foot balance was measured as 33.64 seconds in the group of service period between 5 and 10 years, and side-step was measured as 35.31 times in the group of service period less than 5 years. The standing trunk flexion was measured as 10.54cm for the seamen whose service period is between 10-15 years, and the trunk extension was measured as 50.70cm for the seamen whose service period is less than 5 years. And the step test of the seamen whose service period is between 10-15 years was measured as 54.44 numbers, and the number of flickers of the seamen whose service period is less than 5 years was measured as 32.94.

The CTSIB (Clinical Test of Sensory Integration on Balance) using high sensitive pressure sensors is normally used to assess the sense of balance in hospital. It takes an objective measurement of the amount of sway that occurs in the body trunk by observing the change in the center of pressure (CoP) on the foot at the upright posture. In this paper, we would like to propose method to easily measure trunk sway in home. Although the Wii balance board(WBB) is used for games, it can measures the center of pressure, which is highly correlated. The Wii remote controller(WRC) is inexpensive compared to the WBB, but it has problems with estimation of trunk sway because it can't measure pressure directly like WBB. We collected data from 10 normal subjects (5 males, 5 females) from two devices in order to compare the CoP from WBB and the center of mass (CoM) from WRC. The results of WRC and WBB was similar when the data were analyzed by the convex hull and ellipse area.

A rock slide in amount of 100 tons in weight happened at 7: 10 a.m., 4th October 1982, on the southwestern ridge of Mt. Seunghag, Busan City. The original rock mass of the rock slide is located 850m west from the Dangri Crushed Stone Quarry. The geology of the area consists of agglomerate, andesite, andesitic tuff, and shale hornfels of the Cretaceous Yucheon Group. The rock blocks were first shifted along the steep joint plane on an andesite outcrop at the site and then to the eastern foot of the mountain slope where some private houses are placed. The mountain slope is covered with thick superficial soil. A slided monolithic-block with 83 tons in weight from the rock slide met with an accident of striking against a house with a tremendous force, to which much damage was done as much as its half was destroyed. The rock-slided block pierced the board-floored room only posited at the center and by the bedroom of the house making a pass like a bullet hole, and hence cut a big pine tree with 24 centimeters in diameter at a distance of 26 meters down the house. However nobody was killed or injured in the stricken house, though seven family members were stayed therein at the very time of accident. They really met a rare opportunity in an unhappy disaster. Measurements of the rock slide were made in the course of the field survey. The monolithic mass was transported by way of saltation, rolling, and sliding to a distance of 300 meters down along the slope dipping 30$^{\circ}$ east. It took about 16 seconds front tile outcrop to the terminal. The acceleration value of the monolithic rock slide is 2.35m/sec$^2$.

In this study, 20 men and women in their 20s were divided into a footboard passive stretching group and a manual passive stretching group. After stretching was applied to the soleus for 5 weeks, a comparative analysis was performed on the range of motion(ROM) of the ankle joint to determine changes in the flexibility of the soleus. Both the footboard stretching group and manual stretching group first performed stretching for 15 sec, followed by a 10-sec break. One set consisted of performing the above process twice consecutively, and each group had to perform five sets in total. A goniometer was used as a measuring instrument. The results of the experiment were analyzed using a nonparametric analysis, Wilcoxon signed rank test, and Mann-Whitney test. SPSS WIN 18.0 was employed for the statistical analysis. In terms of the comparison of the flexibility before and after the experiment according to the different interventions, the application of footboard stretching to the soleus for 5 weeks resulted in $3.2^{\circ}$ right dorsiflexion (p=.009), $6.98^{\circ}$ right plantar flexion(p=.008), $4.14^{\circ}$ left dorsiflexion(p=.005), and $10.97^{\circ}$ left plantar flexion(p=.007), which were all statistically significant increases. The application of manual stretching led to $6.04^{\circ}$ right dorsiflexion(p=.005), $12.14^{\circ}$ right plantar flexion(p=.005), $7.00^{\circ}$ left dorsiflexion (p=.008), and $16.38^{\circ}$ left plantar flexion(p=.005). Therefore, both footboard stretching and manual stretching were effective in enhancing the flexibility of the soleus. However, statistically significant larger increases in the ROM of the ankle joint were observed in the manual stretching group.

The dorsalis pedis artery (DPA) was renamed from the anterior tibialis artery after it passed under the extensor retinaculum, and DPA travels between the extensor hallucis longus and extensor digitorum longus muscle along the dorsum of the foot. After giving off the proximal and distal tarsal, arcuate and medial tarsal branches, DPA enters the proximal first intermetatarsal space via the first dorsal metatarsal artery (FDMA), which courses over the first dorsal interosseous muscle (FDIM). For detailed knowledge of the neurovascular anatomy of a dorsalis pedis artery flap (DPAF) as a routine reconstructive procedure after the resection of oral malignant tumors, the precise neurovascular anatomy of DPAF must be studied along the DPA courses as above. In this first review article in the Korean language, the anatomical basis of DPAF is summarized and discussed after a delicate investigation of more than 35 recent articles and atlas textbooks. Many advantages of DPAF, such as a consistent flap vascular anatomy, acceptable donor site morbidity, and the ability to perform simultaneous flap harvest using oral cancer ablation procedures, and additional important risks with the pitfalls of DPAF were emphasized. This article will be helpful, particularly for young doctors during the special curriculum periods for the Korean National Board of Specialists in the field of oral and maxillofacial surgery, plastic surgery, otolaryngology, orthopedic surgery, etc.

This study selected the fifth and sixth graders of elementary school in Jeollanamdo who can express their opinions of safety consciousness and understand the items of questionnaire as the population. It selected 10 elementary schools under the supervision of Jeonnam Board of Education and sampled 700 students randomly from 2-3 classes in the 5th and the 6th grade. One preliminary survey was conducted to revise and complement the contents and forms of questionnaire with 70 students of a school from Apr. 1 to 6, 2004 and this study was conducted from Apr. 10 to 30, 2004. Data of this study were collected by explaining the purport of study to subjects after obtaining approval of principal and teacher of the school and distributing questionnaires. Total 700 questionnaires were distributed and 681 were collected (97%) and 602 were used for final analysis except 79 lacking responses. The results of this study are as follows. According to demographical characteristics of subjects, 'male' students were 302(50.%) and 'female' students were 300(49.8%) by sex and 'the 5th graders' were 285(47.3%) and 'the 6th graders' were 317(52.7%) in grade distribution. Residents at 'apartment house' were 406(67.4%) in residence type, 'going to school by foot' was 477 students(79.2%), 'high school graduates' were 297(49.3%) in fathers' education, 'high school graduates' were 366 (60.8%) in mothers' education, 'professional and office workers' were 231(38.4%) in fathers' job, 'full-time workers' were 283(47.0%) in mothers' job, and the number of siblings was one except myself in 343 students(57.0%). Respondents on the level of class showing 'good' were 340(56.5%) and those on the degree of adaptation to school life showing 'active' were 349(58.0%). On the characteristics related to safety education, 360(59.8%) responded it was 'very necessary', on the frequency of safety education at school for last one year, 339(56.3%) responded they had 'once or twice', on the frequency of safety education by parents, 279(46.3%) responded they 'often' had it, on the level of safety practice by parents, 347(57.6%) responded they practiced it 'frequently', on the source of knowledge of safety, 223(37.0%) responded they got it from 'parents, siblings and relatives', on the degree of recognizing the need of safety education textbooks, 295(38.5%) responded 'it was needed', on the recognition of necessity of teacher for safety education, 271(45.0%) answered it was very necessary', and on the recognition of qualification of teacher for safety education, 370(61.5%) answered it was 'paramedic'. The mean score of safety consciousness of subjects was 2.72 (SD. 21) of full score 3, having high score over mean score. According to each area, the area showing the highest safety consciousness was safety of fire(2.83), followed by home safety(2.76) and first-aid treatment(2.76), traffic safety(2.71), play and leisure safety(2.66) and school safety(2.56). Items showing statistical differences in the degree of safety consciousness according to demographical characteristics were sex(t=-3.11, p=.002), education(t=2.33, p=.021) and number of siblings(F=3.729, p=.011). In the difference of safety consciousness between both sexes, 'female' students(2.75) showed higher safety consciousness than 'male' students (2.69), and the former also showed higher safety consciousness than the latter in all six areas of school safety, play and leisure safety, traffic safety, fire safety, home safety and first-aid treatment, and there were statistical differences in the areas of play and leisure safety, traffic safety, fire safety and first-aid treatment. According to the differences of safety consciousness by grade, 'the fifth graders'(2.74) showed higher safety consciousness than 'the sixth graders'(2.70) and the former also showed higher safety consciousness than the latter in all six areas of school safety, play and leisure safety, traffic safety, fire safety, home safety and first-aid treatment, and there were statistical differences in the areas of fire safety and home safety. In the safety consciousness by the number of siblings, 'single son or daughter' (2.78) was highest and their safety consciousness was also highest in all six areas of school safety, play and leisure safety, traffic safety, fire safety, home safety and first-aid treatment, and there were statistical differences in the areas of school safety, fire safety and home safety, There were statistically remarkable differences in degree of adaptation to school life (F=15.349, p=.000) and perceived schooling level(F=9.552, p=.000). According to the degree of safety consciousness related to characteristics of safety education, there were statistical differences at the degree of recognizing the need of safety education(F=9.797, p=.000), degree of safety education at school(F=2.595, p=.006), degree of safety education by parents(F=12.709, p=.000), degree of practicing safety by parents(F=17.579, p=.000), source of knowledge of safety education (F=2,715, p=.044), necessity of safety education textbooks(F=3.972, p=.008), need of safety teacher(F=4.137, p=.006) and qualification standard of safety teacher(F=3.016, p=.029).
