Social welfare services for respiratory-disabled persons in Korea are offered based on the respiratory impairment grade, which is determined by 3 clinical parameters; dyspnea, forced expiratory volume in 1 second ($FEV_1$), and arterial oxygen tension. This grading system has several limitations in the objective assessment of respiratory impairment. We reviewed several guidelines for the evaluation of respiratory impairment and relevant articles. Then, we discussed a new grading system with respiratory physicians. Both researchers and respiratory physicians agreed that pulmonary function tests are essential in assessing the severity of respiratory impairment, forced vital capacity (FVC), $FEV_1$ and single breath diffusing capacity ($DL_{co}$) are the primarily recommended tests. In addition, we agreed that arterial blood gas analysis should be reserved for selected patients. In conclusion, we propose a new respiratory impairment grading system utilizing a combination FVC, $FEV_1$ and $DL_{co}$ scores, with more social discussion included.

We searched out court rulings on medical affairs through court library search sites and specialized articles on medically relevant judgments sentenced in 2016. And we selected and analyzed the judgements of the court we considered important as follows. In relation to the medical civil judgements, (1) In the case of applying surgery for female infertility during cesarean section operation but it has not been done, we expressed the regret for the lack of judgment in the process of entering the medical contract, introducing the rights infringed and the scope of compensation, (2) We pointed out that the ruling on the medical malpractice estimation goes out of limit of negligence estimation doctrine, and that the court asked very high degree duty of the traditional Korean medicine doctors to cooperate with Western medicine doctors. (3) In the case of admitting hospital's 100% responsibility, we pointed out the court overlooked the uncertainty and good intention of the medical practice. (4) Additionally, We introduced the cases admitted the hospital's responsibility in the accident related to the psychiatric patients in closed ward. Relating to a medical criminal ruling, we analyzed the supreme court decision about whether the dentist's Botox injection on the patient's face is a medical practice within the scope of the license from the viewpoint whether it is within the possible range of the word. And, concerning decisions on healthcare administration, (1) we analyzed the case about when medical personnel operate multiple medical institutions, whether it is possible to get back medical care costs under the National Health Insurance Law, (2) We commented on the ruling regarding explanation obligation in terms of object, degree, subject of explanation as a prerequisite for permissible arbitrary uninsured benefits. Finally, we reviewed the decision of the Constitutional Court about the Article 24 of the Mental Health Law, which it had allowed for a mental patient to be hospitalized forcibly by the consent of two guardians and a diagnosis of a psychiatrist. Also we indicated the problems of the revised Mental Health Law.

Purpose: Recently, while the authors were experiencing that the epidemic period of rotaviral infection happened more in the early spring, we tried to find out how the outbreaks of rotaviral infection are changing in detail depending on the weather condition since it has something to do with the climate factors and PM10. Methods: Fourteen hundreds seventy nine patients who were proved to be positive to rotavirus were chosen among children less than 5 years old from January 1995 to June 2003. Among various climate factors, monthly average temperature, humidity, rainfall and PM10 were selected. Results: Rotaviral infection was most active in 2002 as 309 (20.9%) patients. It has been the spring that is the most active period of rotaviral infection since 2000. The temperature (RR=0.9423, CI=0.933424~0.951163), rainfall (RR=1.0024, CI=1.001523~1.003228) and PM10 (RR=1.0123, CI=1.009385~1.015248) were significantly associated with the monthly distribution of rotaviral infection. Conclusion: Through this study we determined that the epidemic period of rotaviral infection is changed to spring, which is different from the usual seasonal periods such as late fall or winter as reported in previous articles. As increased PM10 which could give serious influence to the human body, and changing pattern of climate factors such as monthly average temperature and rainfall have something to do with the rotaviral infection, we suppose that further study concerning this result is required in the aspects of epidemiology, biology and atmospheric science.

The engraved line expression in metal crafts is a detailed technique of carving or decorating metal surfaces. This technique engraves a line using a tool on the surface of a metal craft. This technique was used extensively in articles made of various metal materials during the Goryeo Dynasty, and the range of patterns that could be expressed and the width of users was wide. In this paper, based on relics and literature, the concept of line representation of this engraving technique used in the metal crafts of the Goryeo Dynasty and the perceptions and terms of the Goryeo Dynasty were examined. In addition, the users engaged in this craft and the specific patterns and patterns of decoration were reviewed. Through these means, it was possible to confirm various aspects of a technique that was thought previously to involve just simple expression of lines using tools. In addition, through the literature, Geumseokmun Gate, and relics currently being transmitted, it was possible to confirm the utilization patterns of techniques used in various types of objects. Various uses have led to the combination with other metal craft techniques that were popular at the time, and while utilizing unique characteristics of the techniques, this maximized the molding of various patterns. In the meantime, it is true that the intaglio technique in metal crafts has not received much attention compared to the decoration techniques of other metal crafts, such as inlay, embossing, and openwork techniques in which decorative effects are maximized due to the recognition that the technique was used so widely in relics. However, the universality of the technique is premised on its wide use across all eras. As such, it was used in metal craft relics that reflect the various cultural characteristics of Korea and various cultural aspects that are currently passed down. On the one hand, technology has been passed down as a form of intangible heritage that embodies a longstanding craft culture which continues to the present in the fields of sculpture and intangible cultural properties. As such, the universality of Seongak contains many cultural meanings. In addition, the uniqueness of the technique is distinct, and it is deeply related to Goryeo, who was in charge of the use of technology and craftsmanship of the Joseon Dynasty and the metal craft technology that is currently handed down. I think research on future techniques should be continued in depth.

The stock market is constantly changing and sometimes the stock prices unaccountably plummet or surge. So, the stock market is recognized as a complex system and the change on the stock prices is unpredictable. Recently, many researchers try to understand the stock market as the network among individual stocks and to find a clue about the change of the stock prices from big data being created in real time from Internet. We focus on the correlation between the stock prices and the human interactions in Internet especially in the stock message boards. To uncover this correlation, we collected and investigated the articles concerning with 57 target companies, members of KOSPI200. From the analysis result, we found that there is no significant correlation between the stock prices and the article volume, but the strength of correlation between the article volume and the stock prices is relevant to the stock return. We propose a new method for recommending stock portfolio base on the result of our analysis. According to the simulated investment test using the article data from the stock message boards in 'Daum' portal site, the returns of our portfolio is about 1.55% per month, which is about 0.72% and 1.21% higher than that of the Markowitz's efficient portfolio and that of the KOSPI average respectively. Also, the case using the data from 'Naver' portal site, the stock returns of our proposed portfolio is about 0.90%, which is 0.35%, 0.40%, and 0.58% higher than those of our previous portfolio, Markowitz's efficient portfolio, and KOSPI average respectively. This study presents that collective human behavior on Internet stock message board can be much helpful to understand the stock market and the correlation between the stock price and the collective human behavior can be used to invest in stocks.

Purpose : For the control of childhood leukemia, of which the mortality is still high, the basic data for the incidence has a great importance. The authors analyzed the data from 133 new patients with childhood leukemia between 1996-2000 in Busan, Korea. Methods : The data were obtained from 133 new cases(87 males and 46 females from 0 to 15 years old) of childhood leukemia who were residents of Busan and who were admitted to the 4 university hospitals and 11 general hospitals from 1996 to 2000. Results : The total number of the new childhood leukemia patients was 133 between 1996-2000; the average annual number of new patients was 26.6. The age-and-sex adjusted annual incidence rate (/100,000) was in the range of 2.37-4.53(male 2.47-5.29, female 0.76-3.36) with an average of 3.29 (male 4.05, female 2.43). Age-specific annual incidence rate(/100,000) was 3.78 in the 0-4 year age group, 3.51 in the 5-9 year age group and 3.08 in the 10-14 year age group. Of the major types of childhood leukemia, the distribution of ALL was average 71.4%, of AML 23.3%, and of CML 4.5%. Of the major types of leukemia by age range, ALL showed highest in the 5-9 year age group, while AML in 0-4 and 10-14 year age groups. Sex-ratio(male to female) of major type of leukemia was 1.97 : 1 and 1.21 : 1, in ALL and AML groups, respectively, while all were male in CML. Conclusion : The average age-and-sex adjusted annual incidence rate(/100,000) of childhood leukemia in Busan from 1996 to 2000 was 3.29. Compared to data in related articles, this data suggests a steady increase in the incidence of childhood leukemia in the Busan area over the last 20 years since 1981.

Today, administrative legislation is becoming more and more important in that it not only sets the legal life relationship of the people in great detail and detail, but is closely related to the occurrence, extinction, and alteration of rights and obligations held by prisoners. In the United States, the types of administrative legislation are divided into substantive and interpretative regulations, so-called substantive regulations, which give prior notice and opportunity to comment on interested parties through formal or informal administrative procedures in accordance with Article 553 of the Federal Administrative Procedures Act. On the other hand, the interpretation regulation, which is "the regulation established by the Administration for the simple interpretation of statutes," does not require prior notice or comment because it does not affect the people's rights obligations. The Azar v. Allina Health Service, 587 U.S. 1804, 2019 ruling by the U.S. Constitutional Court, subject to this research paper, is about a dispute over a new decision to require Medicare to determine the amount of compensation for care providers that provide medical services for the poor, and should the regulations be regarded as substantive under the Administrative Procedures Act and should not be given a hearing or a simple internal process for processing. Given that the current administrative procedure law of our country stipulates the procedures for administrative pre-announcement through Articles 42.1 and 44.1, but that our courts have not judged violations of legislative pre-announcement procedures under the Administrative Procedures Act so far as to judge the illegality of administrative legislation, the dispute of the U.S. Constitutional Court will provide new implications for controlling legal orders beyond simple legal interpretation and has great significance in terms of readjustment of relevant regulations under future administrative procedures.

Purpose : Chronic renal failure is often accompanied by severe dyslipidemia, a known risk factor for cardiovascular disease. Lipoprotein(a) [Lp(a)] has recently been characterized as a risk factor for atherosclerosis and thrombosis. Cardiovascular disease is the leading cause of death in adult patients on dialysis. However, there are only limited data available concerning risk factors for atherosclerosis in uremic children. We have measured serum levels of lipids, lipoproteins, apolipoproteins and Lp(a) in uremic children with maintenance dialysis. Methods : Ten uremic children with hemodialysis (HD) and 14 with peritoneal dialysis (PD) in our dialysis unit were included in this study. The mean age of HD patients was $162{\pm}59$ months and the male to female ratio was 7:3. The mean age and sex ratio of PD patients were $123{\pm}63$ months and 6:8, respectively. The levels of cholesterol, triglyceride, lipoproteins, apolipoproteins and Lp(a) were measured from serum sampled after 14 hours of fasting. The normal control levels were cited from 2 articles presenting the normal blood lipid and lipoprotein levels of primary school and middle school children in Korea. Results : There was no difference in age, sex ratio, body mass index and duration of dialysis between the HD and the PD group. The serum concentration of the cholesterol, triglyceride and apolipoprotein B were significantly elevated in dialysis patients compared with normal subjects. The serum level of Lp(a) was significantly elevated in only PD group. The serum Lp(a) level was below 30 mg/dl in 13 and above 30 mg/dl in 11 patients. The serum albumin level was significantly decreased in high Lp(a) group than in low Lp(a) group. Conclusion : The uremic children receiving dialysis reveal abnormal serum lipid and lipoprotein profiles. These results suggest that they have a higher risk for coronary heart disease, although there has been no clinical evidence of coronary heart disease at present. A long-term follow-up study of these children to clarify the suggestion should be started now.

The purpose of this study was to analyze the results of 133 studies related to patient compliance published between 1980 and 2001 and to assess the effectiveness of intervention on compliance by using meta-analysis. We collected the existing literatures by using web and manual search 'patient compliance', 'sick role behavior', 'major clinical disease', and 'intervention' as key words and by reviewing content of journals related to medicine, nursing and public health. The compliance interventions were classified by theoretical focus into educational, behavioral, and affective categories within which specific intervention strategies were further distinguished. The compliance indicators broadly represent five classes of compliance-related assessments: (1) health outcomes (eg, blood pressure and hospitalization), (2) direct indicators (eg, urine and blood tracers and weight change), (3) indirect indicators (eg, pill count and refill records), (4) subjective report (eg, patients' or others' reports), (5) utilization (appointment making and keeping, use of preventive services). Quantitative meta-analysis was performed by MetaKorea program which was developed for meta-analysis in Korea. Among the 133 articles, 10 studies were selected through the qualitative meta-analysis process, and then only 6 studies were selected for the quantitative meta-analysis finally. The interventions produced significant effects for all the compliance indicators with the magnitude of common effect size (4.1192) than the non-intervention group in a random effect model. The largest effects were each study for patient of hypertension using health outcome such as blood pressure (0.4679) and diabetes mellitus using direct indicator such as glucose level in blood and urine (0.7753). These results suggest that strategic interventions showed clear advantage for improvement of patient compliance compared with non-intervention group.

Background : Hemoptysis, when massive and untreated, has a mortality rate of over 50 percents, is considered as one of most dreaded of all respiratory emergencies and can have a variety of underlying causes. Bronchial artery embolization (BAE) has become an established procedure in the management of massive and recurrent hemoptysis, and its efficacy is widely documented thereafter by number of articles. However, the long-term success rate of BAE is known to be unfavorable. Risk factors influencing that control failure are inevitably needed. Materials and methods : Seventy-five patients underwent bronchial artery embolization due to massive hemoptysis in Severance Hospital from Jan. 2000 to Jan. 2005. Nine patients' data were not available and could not be contacted with. Finally 66 patients' (48 males, 18 females) medical records were analyzed retrospectively during a mean follow up period of 20.4 months (ranging from 1 month to 54 months). Results : Among 66 patients whose data were available, 23(34.9%) patients had recurrent major hemoptysis. Patients' age, sex, underlying disease, previous intervention history, and number of feeding vessels had no statistical validity as risk factors of recurred major hemoptysis. But bilaterality of lesion, amount of hemoptysis, and pleural thickening were revealed as meaningful factors for predicting relapse (p = 0.008, 0.018, and 0.001, respectively). Conclusion : According to our series, patients presenting with larger amount of hemoptysis, pleural thickening of chest radiography and bilateral lesion are associated with increased risk of major hemoptysis in patients treated with BAE.
