Purpose: The purpose of the study was to evaluate the usefulness and the stability of the superficial medial collateral ligament (MCL) release in posterior medial meniscus root repair. Materials and Methods: We compared 20 patients who underwent posterior medial meniscus root repair with superficial MCL preserved (PM) and 32 patients who underwent posterior medial meniscus root repair combined with superficial MCL release (RM) from April 2006 to September 2010. We excluded the patients combined with other surgery. To evaluate the postoperative valgus instability in RM group, we examined direct tenderness on MCL insertion, the subjective feeling of instability and valgus stress test at 3 months and 1 year follow-up. We compared the tourniquet time between PM group and RM group, and the clinical results were assessed by Lysholm score and International Knee Documentation Committee (IKDC) for the usefulness. Results: All patients had no clinically significant complication related to the superficial MCL release. Three months and 1 year follow-up, there were no positive tenderness test, no subjective symptoms and no significant increase of valgus instability although 5 patients examined grade I valgus instability. The mean tourniquet time was $41.3{\pm}12.7$ minutes in RM group and $53.5{\pm}13.6$ minutes in PM group. There was a significant difference in the tourniquet time between the two groups (P<0.05). Average Lysholm score was $56.8{\pm}5.5$ (range, 44-70) preoperatively and $85.1{\pm}5.8$ (range, 77-94) postoperatively in PM group, and was $56.2{\pm}5.4$ (range, 45-67) preoperatively and $87.4{\pm}3.9$ (range, 82-95) postoperatively in RM group (P<0.001). No significant difference of Lysholm score was found in both groups (P<0.05). Average IKDC scores was $42.6{\pm}3.9$ (range, 30-53) preoperatively and $77.2{\pm}6.3$ (range, 68-92) postoperatively in PM group, and was $42.7{\pm}5.7$ (range, 30-53) preoperatively and $89.6{\pm}2.9$ (range, 84-95) postoperatively in RM group (P<0.05). There was also no significant difference of IKDC score in both groups (P<0.05). Conclusion: The superficial MCL release in posterior medial meniscus root repair is useful to gain a wide surgical field and reduces the tourniquet time and does not lead to postoperative valgus instability. It can be considered clinically useful and safe procedure in medial meniscus posterior root repair.

To assess the accuracy of blood pressure measurement in general hospital nurses, 276 nurses at four hospital in Kyungju city and Pohang city were observed during the study period 20 December 1998 to 29 December 1998. The nurses measuring the blood pressure of simulated patient's were checked by the researcher or 20 items, that are recommended for consideration when doing a blood pressure measurement. Of the six items in the preparation step for measuring blood pressure, the accuracy of 'patients shouldn't talk during the procedure' had the lowest frequency(27.1%) and the other five items were above 80%. Of the ten items on blood pressure measuring technique, the accuracy of the frequency for 'inflating the cuff until the radial or brachial artery pulse is no longer palpable and then adding 30mmHg' was 0%, 'waiting $30{\sim}60$ seconds before reinflating the cuff' was alse 0%, 'rapidly deflating the cuff', 0.3%, 'rapidly and steadily inflating the cuff to the maximal level as per above-mentioned initial systolic pressure assessment step', 0.7%, 'reading the pressure to the nearest 2mmHg mark on the manometer', 10.8%, the remaining items were above 70%. Of the four items on blood pressure recording, the accuracy of 'recording the cuff size' had a frequency of 0.3%, 'recording the patient's position such as sitting, standing or lying position', 10.8%, 'recording the arm or leg which was used for measuring the blood pressure', 53.6%, and 'recording systolic/diastolic pressure', 100%. The variables significantly related to the accuracy of the blood pressure measurement were age, career position at hospital, and qualification education for blood pressure measurement(p<0.01). In the multiple regression analysis, position and qualification education were significant variables(p<0.01). In conclusion, the accuracy of blood pressure measurement was very low, thus, qualification education for blood pressure measurement should be done immediately to improve the accuracy of measurement by nurses in general hospitals.

This study aimed to present cosmetic countermeasures for preventing fast aging process in the middle age and accepting healthy aging both physically and mentally by investigating the perception of aging according to the health condition, lifestyle and psychological condition targeting mid-aged women in 40s to 50s residing in Seoul and Gyeonggi-do Province. The data collection period was from July 25 to Sept 1, 2015. The data was analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. It was shown that as the age was higher, the menopause ratio was higher, drinking, exercise volume and hours of sleep were reduced and the stress and psychological pressure were higher. According to the menopausal status, the status of facial aging showed a significant difference (${\chi}^2=39.692^{***}$, p<.001), and it also showed a difference according to the status of leisure (hobby) activity (${\chi}^2=22.470^{***}$, p<.01). Also, as higher the age and closer to the menopause in items including the progress of aging, anxiety about aging and improvement efforts, more negative perception was shown, indicating that it is necessary to prepare cosmetic countermeasures for mid-aged women in like a second puberty 40s to 50s although aging and menopause around 50s are very natural. If a beauty alternative is provided, it will help them to have a successful retirement.

In this study, we developed a PC - based motorcycle simulator based on the development technology of a virtual patrol motorcycle training system. This simulator has been developed to be applied to a variety of fields such as driving training for beginners, driver factor research, and system development such as ABS, which can be seen in advanced models. The weight of the motorcycle operated by the patrol guards is more than 400Kg. There is a lot of risk due to the nature of work without prior practice. Therefore, we implemented a study on the untilization of physical stress and temporal pressure in emergency situations. In order to get a feeling that the motorcycle simulator is operating in real-life, it is important that the mutual reliable signal transmission and operation feel between the driver and the simulator. In order to achieve this, we developed a system that can apply the sub-systems of the actual vehicle to the motorcycle simulator in order to generate the same operation feeling as the actual vehicle. Based on these results, we have developed a method of generating a feedback queue.

Interferential currents (IFC) and transcutaneous electrical nerve stimulation (TENS) are used for pain management. This study compared the analgesic effects of IFC and TENS on experimentally induced ischemic pain in otherwise pain-free subjects using a modified version of the submaximal-effort tourniquet technique. The subjects were 14 volunteers (7 male, 7 female) without known pathology that could cause pain. Their mean age was $26.7{\pm}2.0$ years. A single-blind, sham controlled, parallel-group method was used. The primary outcome measure was the change in the self-report of pain intensity during 1 of 3 possible interventions: (1) IFC, (2) TENS, or (3) sham electrotherapy. The IFC and TENS were administered on the forearm, and the sham electrotherapy group received no current output via a dummy stimulator. The results show that a 2-way repeated-measures analysis of variance revealed that there was no change in pain intensity during treatment when all 3 groups were considered together. The mean to pain intensity with the IFC intervention was no different than with TENS. Thus, Statistical analysis showed that both interventions decreased the pain intensity ratings significantly and the difference between interventions was not simply insignificant. IFC has been shown to be more comfortable than TENS in present studies and is likely to be better accepted and tolerated by patients, clinical investigation is warranted.

Algal community on the subtidal rocky zone of the South Sea of Korea was divided into two or three sequencing zones. The upper subtidal zone was characterized by the wave exposure-tolerant surf wrack(Pachymeniopsis, Gigartina), which formed dense swirling carpet. Its vertical range was from the surface to $3{\sim}5$ meters in depth, and more deeply extended in turbid waters including Sorido, Yokchido, Pijindo, Manjedo. The mid subtidal zone ranging from 5 to 25 meters in depth was characterized by a large brown algal forest (Ecklenia, Sargassum). But it was generally unrecognizable in that turbid waters, in which the vertical limit of vegetation was at most $10{\sim}15$ meters in depth. The low subtidal zone was characterized by a general lack of algal species and was not easily distinguished from the mid or sometimes from the upper zone. There was a distinct difference in abundance of vegetation between turbid waters and clear waters including Munsom, Kwantaldo, Yosodo, Hongdo, Ch'ujado. In turbid waters the vegetation was much poorer because the tubidity caused from the muddy sediment inhibited an algae to settle down and to grow up. On the basis of the phytogeographical methods using UPGMA, the 10 studied islands were classified into two groups, Munsom and the others. This floristic discontinuity between the two groups might be caused from the difference of water temperature.

Under the pressure of the selection of topics and the presentation rules of mass media, politics in media society increasingly resort to professionalized forms of theatrical staging as a means of self-portrayal. Although these staging methods are not contradictory to what is actually going on in politics, they strongly advantage the tendency to focus exclusively on the staging of an event. Through their competition for public attention, politicians have been developing sophistication regarding placement and staging of events as well as regarding factual information. In the process of this transformation, politics that are issue-related and based on binding decisions are being gradually transformed into symbolic politics. Moreover, through their appearance on TV, politicians first of all need to possess presentational skills which are not necessarily related to their political achievements. Still, presentational skills decide over the success in politics of those politicians. The reason is that a politician who possesses presentational skills is still being perceived as being successful even if his political achievements notedly lag behind. On the other hand, political achievements are being underrated if a politician lacks the talent to present himself in front of the media. “The staging of politics, “politainment”, on the stage of mass media is evolving into a key structure which is responsible for a new coinage of politics in all different kinds of dimensions: the selection of staff, the role of action programs and their impact for the legitimation of political acting, even in relation to therole of pivotal political institutions such as parties and parliaments in the political process. The TV debates during the Bundestag elections of the year 2002 and 2005 are being analyzed and judged as “staging of politics”(politainment). Self-dramatization in media society concerning media discourses about politics and political self-portrayal has become a basic principle of political communication. Self-dramatization is a vital challenge for adequate political communication and content-based orientation in our present media democracies.

Pseudoaneurysm of the ascending aorta following cardiac surgery is very unusual and it is poten- tially fatal. We report here a fourteen year-old female patient with pseudoaneurysm of the ascending aorta following a repair of a congenital ventricular septal defect at other hospital 50 months ago. Although she had a mild superficial wound infection postoperatively, she enjoyed uneventful. life until she visited our hospital for a generalized weakness and exertional dyspnea which developed a month ago. Chest CT and echocardiogram showed partially calcified pseudoaneurysm of the ascending aorta. Two aortic defects were located on the anterolateral ascending aortic wall wkere it was suspected as a previous sites of aortic and cardioplegic cannulation. The internal wall of the pseudoaneurysm was covered with neoendothelium and intervened by septal tissue. Two defects on he aortic wall were oval in shape and about 1.5cm in the greatest diameter The defects were trimmed to make a one large de- fect and it was reconstructed with patch designed from 22mm collagen impregnated double velour Dacron graft. The postoperative course was uneventful.

A human being makes a constant effort to find out what he really is. We try to do a great deal in self-culture to know his own self-nature with miscellaneous ways as Buddhism, Taoism and Confucianism. When we are faced with a difficult problem in life, We utilize own knowledge and wisdom to solve them. Thus there are many result of answer what self-confidence is throughout the devoting oneself to the study of man's life which is expressed poetry and prose. We can see the aspect of liberty life in their poetry and prose which is escaping from their restraints as they are willing to find out their own self-nature and want to attain a state of perfect self-nature in every day life. And they are anxious to be born again in spiritual value and to be a man in liberty with removing the narrow-mindedness, the stupidity, the anger and the absolute ego in their mind. That's what we are want to achieve man's purpose understanding of the human being's life. Here, I have a good such example who is Tao yuan ming. It is not easy to give up fame and wealth for maintaining his doctrines. So We have a high regard for this wisdom between entering into politics and withdrawing from his office. It needs a self-conquest and more courage than entering into politics. Retiring from his office, he returns to the place where is native place everything lives and let live without moral pressure in daily life. Because there is real liberty life and immutable truths.
