Objectives : To analyze the contents of ≪Lingshu·Jingjin≫ and study the standard posture in context of Korean Medicine. Methods : Analyzed the terms related to the name, body region and orientation of Three Yin and Three Yang used in ≪Lingshu·Jingjin≫ to deduce the standard posture of the description. ≪Lingshu·Jingmai≫ was used as supplementary data. Results : The term "Three Yin and Three Yang" in ≪Lingshu·Jingjin≫ is used to indicate regions of the human body, and based on this, terms with orientation were used. Just like 'anatomical position', there is a standard posture in Korean Medicine, and it may seem to be similar overall, but there is a difference in posture in the upper extremity. In ≪Lingshu·Jingjin≫, Greater Yang is the dorsal region, Lesser Yang is the lateral surface region, Yang Brightness is the anterior surface region of the human body. In the body trunk, Three Yin refers to the inner parts of the human body. However, in the lower extremity, Three Yin refers to the medial surface of the legs. The name of the individual Meridian-muscle was given following the region corresponding to Three Yin and Three Yang. In ≪Lingshu·Jingjin≫, there is a basic posture that became the standard posture derived from the description. In an upright standing position, the feet face forward, the fingers naturally extended, and the back of the hand faces outward. The fact that the posture of the thumb is naturally extended is especially reflected in ≪Lingshu·Jingjin≫. This is clearly different from the "anatomical position" and as it can be the base of all areas of acupuncture, it is suggested that it be defined as the "Standard Position of Acupuncture Medicine". Conclusions : Based on our analysis, we suggest the "Standard Position of Acupuncture Medicine" as an upright standing position, with the feet facing forward, the fingers naturally extended, the back of the hand facing outward, and the thumb naturally extended.

This study was performed to evaluate the hyoid bone position and airway in skeletal class III malocclusion and to prove the correlation between airway, hyoid bone position and mandibular position. The sample, considered of 47 class III malocclusion patients for experimmtal group and 52 class I malocclusion students for control group. Twenty three linear and angular measurements about hyoid bone position, airway size, mandibular position were taken from the lateral cephalograms. The differences between skeletal class III malocclusion group and normal occlusion group were compared and the correlation were evaluated statistically. The results obtained were as follows, 1. There were significant difference in S-APH, A-APH, N-APH, LAH-PBR, AA-PNS, PNS-ad between class I and class III malocclusion groups. 2. The hyoid bone was more anteriorly positioned in class III malocclusion group than class I malocclusion group and skeletal airway size in class III malocclusion group was smaller than class I malocclusion group. 3. There were significant difference in several measurements especially vertical and angular measurements of hyoid bone position and airway size between male and female. Usually the measurements in male were larger than female. 4. There were no significant correlation between hyoid bone position and airway size also airway size, and didn't showe significant correlation with mandibular position, 5. S-APH showed negative correlation with Wits appraisal and A-APH, N-APH showed positive correlation with Wits appraisal. On the contrary vertical measurements of hyoid bone position showed positive correlation with lower facial height.

The light buoy installed on the sea is always flexible, because it is affected by the weather as well as passing vessels. The position of the light buoy can be cached through the AtoN AIS (Automatic Identification System) and RTU (Remote Terminal Unit). This study analyzed the position data of the light buoys for the last five years (2017-2021), as well as the distribution of the light buoys within the maximum separated position. As a result, there was a basic error of 17.9% in the position data. Additionally, the separated position error of 197 light buoys to be analyzed was 70.64%, and the AtoN RTU was worse than the AtoN AIS by equipment. On the other hand, as a result of the plotting the position data of the light buoy, it was classified into four types. The most common percussion center type, the percussion center dichotomous type in which the position is divided into two zones based on the chimney, the central movement type with a fluctuating center, and the drag type, in which the position is deviated from the center for a certain period. Except for Type-1, the type was determined according to the position at which the light buoy was installed. This study is the first to analyze the position data of the light buoy, and it is expected that it will contribute to the improvement of the quality of the position data of the light buoy.

Purpose: The purpose of this study was to examine the effects of position change from supine to Fowler's on back pain and discomfort in patients who remained on bed rest after undergoing PCIs with a vascular closure device. Methods: Data was collected from 35 inpatients who were hospitalized in coronary-care unit to perform PCIs with a vascular closure device at S hospital in Seoul from December, 2006 to May, 2007. Back pain, discomfort, presence and grade of bleeding and hematoma from femoral arterial puncture site and blood pressure/pulse rate were measured prior to, 10 minutes, 1 hour and 2 hours after position change. Data was analyzed with descriptive statistics, $x^2$ tests and t-tests using SPSS/WIN 12.0 for Windows program. The level of significance (${\alpha}$) was set at 0.05 for this study. Results: We found that there was no significant difference in back pain and discomfort in 10 minutes after position change between the two groups. However, the experimental group reported significantly less back pain and discomfort than the control group in 1 hour (p<.01, respectively) and 2 hour (p<.01, respectively) after position change. There was no significant difference in the presence and grade of bleeding and hematoma at the puncture site, blood pressure, and pulse rate in 10 minutes, 1hour and 2hours after position change between the two groups. Conclusion: Fowler's position change after PCIs in, therefore, safe and effective method of reducing back pain and physical discomfort without causing additional bleeding and changes in blood pressure and pulse rate.

This study examines the relative competitive position of korean fisheries products market over period of 2001 to 2005 and selects strategic exported goods from its position provide against concluding FTA agreement with China and Japan. The portfolio approach is used to develope competitiveness-market share matrix. The position of each export countries on the competitiveness market share matrix will be in one of nine cells, with differing implications for their role in korean fisheries products market. Based the competitiveness market share matrix, each export countries are divided into first cell type, third cell type and ninth cell type and the items of ninth cell type are chosen as strategic exportable goods. The results of this study are summarized as follows: First, in the case of each country change aspect, China is trending to decrease quantity but shows number of item that increase gradually with high share still, and look trend that increase third cell type item too gradually, and in case of first cell type item is that competitive position is high more relatively than the Korea. In the case of Japan, ninth cell type item is falling gradually, and share does not show big change generally in case of first cell type item. Second, in the case of strategic exportable goods that analyze using domestic competitive position cell type and MCA with competitive position in domestic fisheries products market and export market, was appear by codfish(frozen), cuttle fish(frozen) etc. in case with China, and by mackerel(frozen), other sea bream(frozen), laver(dry), bathing(dry) etc. in case with Japan. And analyzed goods that have all export competitive advantages in both countries are roes of alaska pollack(frozen), other roes of fish(except frozen roes of alaska pollack), squid(frozen) etc.

Objective : This study compares Video laryngoscope and Direct laryngoscope in tracheal Intubation on rapidity and accuracy by paramedic and aims to improve efficiency of airway management and survival rate in pre-hospital treatment for the patients with severe trauma, cardiac arrest or dyspnea caused by acute diseases. Methods : 60 paramedics were recruited from 13 fire stations located in C province. With the consent of the paramedics, likelihood ratio test was carried out and they were divided into two different groups; DL group (30) and GVL group (30). Regarding intubation conditions, difficult airway grade I, grade II and grade III as well as sniffing position and neutral position were examined. This study also compared between ambulance in motion and in stand still. Frequency, average and standard deviation were analyzed with statistics program, SPSS WIN 17.0 and repeated measure design was introduced to examine inter-relations between position, grade and groups. Results : Intubation was performed more rapidly in neutral position and GVL than in sniffing position and DL(F = 15.260, p = .000). Rapidity value was better with grade I and grade II than grade III and better with GVL than DL(F = 32.629, p = .000). Accuracy value was higher with neutral position and GVL than sniffing position and DL(F = 5.008, p = .011). grade III was less accurate than grade I, grade II and GVL was more accurate than DL(F = 10.966, p = .000). Ambulance motion status did not show any statistically significant differences in accuracy and rapidity. Conclusion : Given this study results, neutral position is better for the patient with severe trauma. For a better survival, GVL intubation can be considered since GVL can enhance accuracy as well as rapidity regarding difficult airway. Since there is no significant differences in ambulance motion factors, intubation can be recommended even in moving ambulance for shortening traveling time to a hospital.

In order to convert the mechanical movement of a linear generator to electrical power, the amateur current of the generator is controlled in accordance to the mover position. A linear encoder, usually used for direct detection of the mover position, not only is vulnerable to mechanical vibration, but also imposes significant constraint on the mechanical design of the generator system. Thus, this study proposes a method for indirect estimation of the mover position with emfs induced in amateur coils. The estimation algorithm is validated with simulation study.

If the implant is planted in the wrong position or direction, it is disadvantageous for stress distribution, and it is easy to cause complications such as screw loosening, abutment fracture, and implant fracture. If the position or orientation of the implant is not good, efforts should be made to minimize the problem through proper implant prosthetic treatment. In this article, the prosthetic method for facilitating future maintenance in cases with poor implant placement or orientation will be presented.

Switched reluctance motor(SRM) has the advantages of simple structure, low rotor inertia, and high poer rate per unit volume. However, position sensor isessential in SRM in order to synchronize the phase excitation to the rotor position. The position sensors increase the cost of drive system, and tend to reduce system reliability. This paper investigtes the speed control of sensorless SRM. The proposed system consists of position detection circuit, dwell angle controller, digital logic commutator, PI speed controller and 4-phase inverter. The performances in the proposed system are verified through the experiment.
