The Korean Medicine in the middle period of the Chosun Dynasty, with its clear independence, has made an excellent display of originality and superiority in the world medicine. By pinpointing its merits, classifying its lineal descent, and examining its relation with present Korean Medicine we can draw the following conclusions. First, the study on the history of Korean Medicine should, in terms of time, grasp the generational stream and, in terms of space, examine the relation with medicines of neighbouring countries, with both an inner and outer way of observing. Secondly, it is but a manifestation of the colonial view of history to classify the 460 years from Tae-jo(太祖) to Cheol-jong(哲宗) as Mordern Period of Korean Medicine. Therefore, the 250-year period between the mid-16th century of Myung-jong(明宗) to the late-18th century of later Jeong-jo(正祖), which saw a pivotal development of the national medicine as a practical medicine based on experiences, should be established as the period of Korean Medicine in the mid-Chosun dynasty. It is required from both nationalistic view of history and history as a positive science. Thirdly, Korean Medicine in the mid-Chosun period was developed with an emphasis on an independent development and creative succession of the national medicine, which was succeeded to the late-Chosun period. Fourthly, medical thought in the mid-Chosun period was much influenced by, and based on the practicality of, Shil-hak(or practical science : 實學) as was the current of the times. Fifthly, though medicine in the mid-Chosun period was generally developed, the recipes for the measles, epidemic and smallpox were especially developed owing to rage of epidemics, and the development of the acupunture as a military medicine was the most c lear because of the two major wars against the Japanese and Chinese, respectively in 1592 and 1636. Sixthly, Whang doh-yeon(黃道淵)'s Bangyak-happyeon(方藥合編), Lee je-mah(李濟馬)'s Tongui-susebawon(東醫壽世保元) and Lee kyu-jun(李奎晙)'s Uigam-jungma(醫鑑重磨) are representative medical books, in the late-Chosun period, which creatively succeeded national medicine. Seventhly, the lineage of national medicine flows from Hyangyak-jipseongbang(鄕樂集成方) Uibangryuchui(醫方類聚) Gugeupbang(救急方) to Uirimchualyo(醫林撮要) Tonguibogam(東醫寶鑑) Uimunbogam(醫門寶鑑) Jejung-sinpyeon(濟衆新編) and to Bangyak-happyeon(方藥合編) Tongui-susebawon(東醫壽世保元) Uigam-jungma(醫鑑重磨). These books are representative medical books in the early middle and late Chosun period respectively. On the basis of the above facts, it is clear that the orthodoxy of national medicine is in the direction of a creative succession and that is the best way to keep the spirit of Korean medicine today.

Purpose : To confirm the efficacy of arthroscopic synovectomy for the pigmented villonodular synovitis in the knee. Materials and Methods : We analysed 8 patient(9 cases) that were diagnosed and performed arthroscopic synovectomy as pigmented villonodular synovitis from July 1992 to May 2000. The diagnosis was confirmed by pathologist. The average follow-up period was 29 months(range, $15\~48$ months). The average age at initial visit was 40.4 years(rage, $15\~67$ years). Male were 6 cases and female 2 cases. The average duration from onset of the symptom to the operation was 23 months($2\~86$ months). Previous history of the trauma was noted in 2 case. There was 1 case involved both knee joints. Results : According to the athroscopic findings, there were 4 localized forms and 5 diffuse forms. At preoperational examinations, the average of flexion contracture was $4.4^{\circ}(0\~5^{\circ})$ and that of the further flexion was $117.8^{\circ}(90\~135^{\circ})$. At last follow-up examinations, the knee range of motion was normalized, the average of flexion range was $133.9^{\circ}(120\~140^{\circ})$. All patients had improvement in pain, swelling and range of motion and there was no evidence of recurrence. Conclusion : In the pigmented villonodular synovitis, arthroscopic synovectomy can be considered one of the good modality to expect good results.

Childhood psychic trauma appears to be a crucial factor in the development of serious disorders both in childhood and in adulthood. Traumatized children show strong tendency to revisualize or re-feel a traumatic events. Play and behavioral reenactments are frequent manifestations of both the single blow and the long-standing traumas in childhood. Those children who suffer the results of single, intense terror appear to exhibit detailed memory, retrospective reworkings and misperceptions. In long-standing or repetitive trauma, children would show psychic numbing, self-hypnosis, dissociation and rage. Child's brain is undergoing critical and sensitive periods of differentiation. During this time, developing central nervous system is exquisitely sensitive to stress. Stressor-activated neurotransmitters and hormones can play major roles in neurogenesis, migration, synaptogenesis, and neurochemical differentiation. Internal opiate system operates in some trauma and causes the victim to fail to respond, to avoid, to shut off feelings. Evidence is also accumulating in traumatology that dysfuntion of locus coeruleus and ventral tegmental neucleus system leads to catecholamine receptors hypersensitivity. This change result in hypervigilance, increased startle, affective lability, and increased autonomic nervous system hyperreactivity. Another site of action of trauma on the brain is hypothalamic-pituitary-adrenal axis. Individuals with PTSD do not have enough cortisol to halt the alarm reaction. When children are exposed to long-standing extreme events, massive attempts to protect the psyche and to preserve the self are put into gear. These developmental traumas mobilize various kinds of defense mechanisms. Massive denial, dissociation, self anesthesia, identification with aggressor and aggression turned against the self often lead to profound character changes in the youngsters.

This is a qualitative study conducted to understand and explain the experience of nursing students' exploring historic sites of independence movement overseas. The study's participants were 24 nursing students in the first and second graders who participated in a program to explore the historic sites of independence movement overseas at a college in C County, Gyeongsangbuk-do. The data collection period was from December 23, 2017 to December 25, 2017. The data collection was carried out in an open self-reporting process, and the collected data were analyzed using the qualitative content analysis method of Krippendorff[13]. Based on the analysis of the experience of nursing students' exploring historic sites of independence movement overseas 19 sub-theme, 10 themes, and 4 categories were derived. The four categories are "Our History Represented in the wake of the independence movement", "Footprint projected of an independent activist ", " Rage Boiling But Hope Remaining", "blooming patriotism through reflection". The results of this study provided an understanding of nursing students' experience in exploring the historical sites of independence movement and have shown that nursing students had the opportunity to recognize the history of independence movements, inspire patriotism and reflect on their attitude as nurses. In addition, institutional efforts and resources should be supported to address the lack of policies on the preservation of the historic sites for independence movements overseas, which are dependent on the private sector.

The price hike of university meal service hasn't increased as much as the rise in prices. Accordingly, it is necessary to make the school meal service better and make its image students think of improved, and it needs a proper increase. This study examines the permission evaluation of price hike of university meal service by analyzing students' behavior of using school meal service, restaurants they use, the price range of the meal service. It also investigates how the management of university meal service influences its price hike rate. The result of the study is as follows. Students are sensitive to price increase of school meal service because it hasn't been improved compared with its price. As a result of the evaluation of satisfaction with price in school meal service, its quality is bad compared with the restaurants outside school even though there isn't much difference between their prices. In addition, the cross tabulation analysis shows that there is significant difference between the restaurants students use and the price hike rate; there isn't significant difference between the price range of the meal service and the price hike rate; there is significant difference between the proper management of the meal service and the price hike rate. This study has a limit because it analyzes proper price and the quality of the restaurants comparing school cafeterias and the restaurants outside a university; however, it should be basic information for the improvement of university meal service in that the second most important reason why university students use a school cafeteria is price.

Purpose: The old reference range of serum anion gap(AG) may be excessive compared with value measured by new electrolyte analyzers. Therefore, we studied to establish a new reference range of AG using an autoanalyzer. Methods: With the use of analyzer(Hitachi 747 by enzymatic methods), serum Na and Cl were measured, and with the use of analyzer(CX-3 by differental rage pH), serum $TCO_2$ was measured. We measured AG(=Na-($Cl+HCO_3$)) in 395 stable patients with normal serum albumin and creatinine levels of the pediatric in-patients and out-patients for preoperative examination from march 1997 to July 1997. Results: The normal serum$ AG(mean{\pm}SD)$ were neonate, $11.2{\pm}3.2$ mEq/L; infancy, $11.8{\pm}2.7$ mEq/L; early childhood, $12{\pm}2.7$ mEq/L; late childhood, $11.7{\pm}3.2$ mEq/L; adolescence, $9.6{\pm}2.7$ mEq/L; adult, $9.0{\pm}2.7$ mEq/L. Normal serum AG in more than 10 years of age was significantly lower than the previous normal value and also the difference of AG between more than 10 years and less than 10 years was statistically significant(P<0.05). Conclusions: We suggest to measure serum AG according to each type of analyzers.

HPL-4 is a new herbal formulation developed for the treatment of osteoarthritis. In this study, we took HPL-4 to develop a method for simultaneous determination of nine marker compounds (protocatechuic acid, chlorogenic acid, liriodendrin, nodakenin, ${\beta}$-$\small{D}$-(3-O-sinapoyl)frucofuranosyl-${\alpha}$-$\small{D}$-(6-O-sinapoyl)glucopyranoside, quercitrin, 6-gingerol, decursin and decursinol angelate) present in the formulation. The analytes were separated by UPLC system consisting of diode array detector at 205 nm and RP-amide column, and solvent system of $ACN/0.1%H_3PO_4$. Analytical method was validated to evaluate its linearity, limit of detection (LOD), limit of quantification (LOQ), precision, and accuracy. All standards showed good linearity ($R^2$ >0.99) in the rage of $0.25-400.0{\mu}g/mL$. The LOD and LOQ were within the range of 0.021-0.148 and $0.070-0.448{\mu}g/mL$, respectively. Intra- and inter-day precision was less than RSD 4.0% and the accuracy was range from 92.00-104.81% with RSD<4.2%. The results suggest that the developed UPLC method is precise, accurate and effective, and could be applied for quality control of HPL-4 formulation.

Recently, wireless LAN are often applied in home or office because of its various of convenience. Frequency rage of wireless LAN specified by IEEE 802.11a is at 5.2 GHz and IEEE 802.11b is 2.4 GHz. But in offices with wireless LAN devices, reflection of waves against walls, ceilings, floors and desks made of metal creates multipath problems that reduce communication speed and lose data. These problems can be solved by using EM wave absorber. In this paper, we designed and fabricated EM wave absorbers using MnZn-ferrite, sendust, carbon and CPE(Chlorinated Polyethylene). The EM wave absorber with the ratio of MnZn-Ferrite : sendust : CPE=64 : 16 : 20 wt.% has thickness of 3.7 mm and absorption ability more than 17 dB at 2.4 GHz and the EM wave absorber with the ratio of MnZn-ferrite : carbon : CPE=40 : 15 : 45 wt.% has thickness of 3.8 mm and absorption ability more than 23 dB at 5.2 GHz.

Felodipine is a calcium antagonist that lowers blood pressure by reducing peripheral resistance by meas of a direct, selective action on smooth muscle in arterial resistance vessels. Futhermore, it have been approved for the effective in angina pectoris and cardiac failure. The purpose of the present study was to evaluate the bioequivalence of two felodipine extended release (ER) tablets, Splendil (YuHan Corporation) and Stapin (Hana Pharmaceutial Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). The felodipine release from the two felodipine formulations in vitro was tested using KP VIII Apparatus II method at pH 6.5 buffer solution. Twenty six healthy male subjects, $22.73{\pm}1.78$ years in age and $66.66{\pm}7.28\;kg$ in body weight, were divided into two groups and a radomized $2{\times}2$ cross-over study was employed. After two tablets containing 5 mg as felodipine were orally administered, blood sample was taken at predetermined time intervals and the concentrations of felodipine in serum were determined using column-switching HPLC method with UV detector. The dissolution profiles of two formulations were similar at pH 6.5 buffer solution. Besides, the pharmacokinetic parameters such as $AUC_t,\;C_{max}\;and\;T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t\;and\;C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the Splendil were 2.53%, 1.32% and 18.32% for $AUC_t,\;C_{max}\;and\;T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance rage of log(0.86) to log(1.25) $(e.g.,\;log(0.86){\sim}log(1.20)\;and\;log(0.89){\sim}log(1.23)\;for\;AUC_t,\;C_{max},\;respectively)$. Thus, the criteria of the KFDA guidelines for the bioequivalence was satisfied, indicating Stapin ER tablet and Splendil ER tablet are bioequivalent.
