In this paper we have investigated latitudinal variations of the poleward boundary of the nightside auroral oval when the magnetosphere is hit by an enhanced solar wind dynamic pressure front. We used precipitating particle data obtained from Defense Meteorological Satellite Program satellites to identify the locations of the boundary before and after enhanced pressure impacts. The boundary locations are represented by a parameter called "b5e". After performing the analysis for a number of events, we found that the basic effect of the solar wind pressure increase impact is often (but not always) to move the poleward boundary of the nightside auroral oval poleward. However, this effect can be often modified by other factors, such as simultaneous variations of the interplanetary magnetic field with a pressure increase, and thus the boundary response is not necessarily a poleward shift in many cases. We demonstrate this with specific examples, and discuss other possible complicating factors.

Objectives: The purpose of this study was to classify determinants of cost increases into two categories, negotiable factors and non-negotiable factors, in order to identify the determinants of health care expenditure increases and to clarify the contribution of associated factors selected based on a literature review. Methods: The data in this analysis was from the statistical yearbooks of National Health Insurance Service, the Economic Index from Statistics Korea and regional statistical yearbooks. The unit of analysis was the annual growth rate of variables of 16 cities and provinces from 2003 to 2010. First, multiple regression was used to identify the determinants of health care expenditures. We then used hierarchical multiple regression to calculate the contribution of associated factors. The changes of coefficients ($R^2$) of predictors, which were entered into this analysis step by step based on the empirical evidence of the investigator could explain the contribution of predictors to increased medical cost. Results: Health spending was mainly associated with the proportion of the elderly population, but the Medicare Economic Index (MEI) showed an inverse association. The contribution of predictors was as follows: the proportion of elderly in the population (22.4%), gross domestic product (GDP) per capita (4.5%), MEI (-12%), and other predictors (less than 1%). Conclusions: As Baby Boomers enter retirement, an increasing proportion of the population aged 65 and over and the GDP will continue to increase, thus accelerating the inflation of health care expenditures and precipitating a crisis in the health insurance system. Policy makers should consider providing comprehensive health services by an accountable care organization to achieve cost savings while ensuring high-quality care.

Objectives: Postoperative nausea and vomiting (PONV) is considered as one of the most incessant and anguishing factors for patients who have surgery under general anesthesia. The occurrence of PONV after orthognathic surgery can lead to dehydration, infection, bleeding at the surgical site, and patient discomfort, all of which leave a patient with a negative impression of anesthesia and surgery. The purpose of this study is to assess the incidence of PONV after orthognathic surgery and to correlate it with factors related to patient, anesthesia, and surgery. Materials and Methods: A 10-year retrospective survey was done for patients who underwent orthognathic surgery between January 2008 and March 2018. The incidence of PONV was evaluated, correlations with factors related to patient, anesthesia, and surgery were studied, and the duration between the end of surgery and the occurrence of the first episode of PONV was tabulated. Results: The medical records of 109 patients were screened, out of which 101 satisfied the inclusion criteria. Amongst these patients, 60 patients (59.4%) suffered from PONV. Patient's sex, induction agent used, intravenous fluids administered intraoperatively, duration and type of surgery, and the presence of a nasogastric tube were seen to have a significant influence on precipitating PONV. It was noted that among the patients who suffered from PONV, 61.7% of them experienced it 48-96 hours after the end of surgery. Conclusion: Despite the improved anesthetic equipments, drugs, and surgical techniques currently used, the incidence of PONV was high in our study. Certain factors that were seen to influence PONV in this study need to be considered in order to develop an efficacious protocol to reduce PONV in orthognathic surgeries.

A theroretical study was made on the psychodynamism of somatoform disorder. Somatoform disorder is caused by a defense mechanism of somatization. Somatization is the tendency to react to stimuli(drives, defenses, and conflict between them) physically rather than psychically(Moore, 1990). Ford(1983) said it is a way of life, and Dunbar(1954) said it is the shift of psychic energy toward expression in somatic symptoms. As used by Max Shur(1955), somatization links symptom formation to the regression that may occur in response to acute and chronic conflict. In the neurotic individual psychic conflict often provokes regressive phenomena that may include somatic manifestations characteristic of an earlier developmental phase. Schur calls this resomatization. Pain is the most common example of a somatization reaction to conflict. The pain has an unconscious significance derived from childhood experiences. It is used to win love, to punish misdeeds, as well as a means to amend. Among all pains, chest pain has a special meaning. Generally speaking, 'I have pain in my chest' is about the same as 'I have pain in my mind'. The chest represent the mind, and the mind reminds us about the heart. So we have a high tendency to recognize mental pain as cardiac pain. Kellner(1990) said rage and hostility, especially repressed hostility, are important factors in somatization. In 'Psychoanalytic Observation on Cardiac Pain', psychoanalyst Bacon(1953) presented clinical cases of patients who complained of cardiac pain in a psychoanalytic session that spread from the left side of their chests down their left arms. The pain was from rage and fear which came after their desire to be loved was frustrated by the analyet. She said desires related to cardiac pain were dependency needs and aggressions. Empatic relationship and therapeutic alliances are indispensable to psychotherapy in somatoform disorder. The beginning of therapy is to discover a precipitating event from the time their symptoms have started and to help the patient understand a relation between the symptom and precipitating event. Its remedial process is to find and interpret a intrapsychic conflict shown through the symptoms of the patient. Three cases of somatoform disorder patients treated based on this therapeutic method were introduced. The firt patient, Mr. H, had been suffering from hysterical aphasia with repressed rage as ie psychodynamic cause. An interpretation related to the precipitating event was given by written communication, and he recovered from his aphasia after 3 days of the session. The second patient was a dentist in a cardiac neurosis with agitation and hypochondriasis, whose psychodynamism was caused by a fear that he might lose his father's love. His symptom was also interpreted in relation to the precipitating event. It showed the patient a child-within afraid of losing his father's love. His condition improved after getting a didactic interpretation which told him, to be master of himself, The third patient was a lady transferred from the deparment of internal medicine. She had a frequent and violent fit of chest pains, whose psychodynamic cause was separation anxiety and a rage due to the frustration of dependency needs. Her symptom vanished dramatically when she wore a holler EKG monitor and did not occur during monitoring. By this experience she found her symptom was a psychogenic one, and a therapeutic alliance was formed. later in reguar psychotherapy sessions, she was told the relaton between symptoms and precipitating events. Through this she understood that her separation anxiety was connected to the symptom and she became less terrifide when it occurred. Now she can travel abroad and take well part in social activities.

Background: Conservation of blood during cardiac surgery is important because of the shortage of donor blood, risks associated with transfusion, and the costs of allogeneic blood products. This retrospective study explored the feasibility of off-pump coronary artery bypass (OPCAB) without transfusion. Methods: One hundred and two consecutive patients underwent OPCAB from January 2007 to June 2012 at Hallym University Sacred Heart Hospital. Excluding 10 chronic renal failures patients, 102 patients were enrolled. Their characteristics, clinical data, and laboratory data were analyzed. We investigated the success rate of OPCAB without transfusion according to preoperative hemoglobin (Hb), and the cutoff point of the Hb level and the risk factors for transfusion. We implemented multidisciplinary blood-saving protocols. Results: The overall operative mortality and the success rate of OPCAB without transfusion were 2.9% (3/102) and 73.5% (75/102). The success rates in patients with Hb<11, 11 70 years, diagnosis of acute myocardial infarction, preoperative Hb and creatinine levels, and operation time. The events precipitating the need for transfusion were low Hb level in 9 patients and hypotension or excessive bleeding in 18 patients. Conclusion: The preoperative Hb level of >11 facilitates OPCAB without transfusion. These results suggest that transfusion-free OPCAB can be performed by modifying the risk factors and correctable causes of transfusion and improving various blood salvage methods.

This study is to identify the factors deterring or precipitating the exit from welfare recipiency to labor market in the Korean social assistance program. The results from the empirical analyses of the Korea Welfare Panel Study(KOWEPS) show that the duration dependency is not due to increasing welfare dependency with duration, but to the fact that longer stayers have many vulnerable conditions to escape from poverty. Particularly, the main factors determining the transition from recipiency to labor market are not individual or household characteristics such as human or social capital. Those having adolescents of secondary education in their households or participating in some effective labor market program such as job placement service tend to have significant effects on the exit rates from recipiency. That means that the institution-related factors such as the education and health supports combined with benefits and the effective labor market programs are important in the translation from recipiency to labor market of working-age recipients in the Korean social assistance scheme.

Purposes of this study were to identify the factors associated with behavioral Intention to social distancing (BItSD) in a loss versus gain advertising context. This study is a secondary analysis of data surveyed after randomly allocating one of the loss and gain message framing advertisements for the prevention of coronavirus disease-2019 (COVID-19) infection to 379 adults aged 19 and over living in Korea in early March 2021. Attitude toward advertisement (𝛽=.03, p<.001), involvement in COVID-19 (𝛽=.14, p=.006) and emotional stigma (𝛽=-0.17, p<.001) were associated with BItSD, and the explanatory power of these variables was 19% (Adjusted R²=.19). Therefore, when health care professionals communicate with the public, they should develop the strategies to increase public people's involvement in the information and to induce positive advertising attitudes, and provide the effective messages to prevent stigma by accurate information.

Condylar resroption, or condylysis can be defined as progressive alteration of condylar shape and decrease in mass. Although the cause is unknown, condylar resorption has been assocated with rheumatoid arthritis, systemic sclerosis, systemic erythematous, steroid usage, orthodontic treatment and orthognathic surgery. In most case, however, there is no identifiable precipitating event. Hence the term is idiopathic condylar resorption. With condylar resorption, the bone loss is resulting in a loss of posterior support in the involved condyle and the mandible can then shift. As a result, the most patients exhibit occlusal change, openbite, retrognathism, and a decrease in posterior face height. This article reports cases of condylar resorption. And the author will review factors capable of changes of condyle, pathogensis and management of conylar resorption.

Delirium independently contributes to poor outcomes including prolonged hospital stays and increased risk of mortality. The reported prevalence of delirium in variety of medical and surgical hospital settings is from 15% to 70% ; delirium is, therefore, one of major reason for consultation that is required for psychosomatic interventions. This article reviews the psychosomatic interventions to treat delirium including 1) identification of risk factors and precipitating causes ; 2) non-pharmacological interventions, such as modifying treatment environment and educating patient's family and care-giver ; and 3) pharmacological approaches to control the various symptoms that are frequently presenting with delirium.

This study was done to determine the situations of stress incontinence(SI) and the differences in general characteristics, obstetrical history and SI related variables between women with stress incontinence and normal women. The design for study was a descriptive study. The number of subjects consisted of 156 women who were selected by systematic random sampling in Kwangju city. Data collection was done with the modified Hendrickson's Stress Incontinence Scale(1981) which was analyzed using frequency and percentiles. The results were as follows : 1. The stress incontinence (SI) rate of the sample was 64.1% and the majority of the women(40.9%) had experienced SI for a period of five years(the mean period was 2.7 years) without any treatment or care(83.0%). The amount of SI was from one drop(40.0%) to one teaspoon(16.7%) daily. 2. Items on the SI scale had the scores ranging from 4 to 44 with a mean score of 13.7 which showed mild SI. 3. The priority of provocative factors for SI were abdominal tightening(83%), coughing(58%), laughing(52%), sneezing(40%), steeping(18%), sudden standing(17%), nose blowing(13%), heavy exercise(11%), rapid walking up-stairs(10%) and excitment (9%) in that order. 4. There were no significant differences in age, education, spouse, job and income between the women with SI and the normal women. 5. There were no significant differences in the age at the last delivery, age of last baby. number of vaginal, or cesarean deliveries, or abdominal operations between the women with SI and the normal women. It can be concluded that SI in women has a high incidence nth various provocative factors but it is relatively mild SI on a daily basis and generally there has been no treatment. It is suggested that a descriptive study of emotional problems and precipitating variables in SI women will increase the knowledge of SI.
