The purpose of this research is to analyze relationships among the habitual life, stress, and constipation and to help prevent and improve the constipation among women's university students. This is a descriptive interrelated research that has targeted women's university students. The data had been collected for 10 days, from December 22, 2003 to December 31, 2003. The survey was carried out to the 295 women's university students that had been randomly selected by visiting four-year-course colleges and universities in Seoul. The survey consists of 78 questions: five questions on the general trait, 11 questions on the habitual life, 51 questions on the stress, and 11 questions on the constipation. There are seven questions on the dietary life, four questions on exercising, and Shin Jung Ran's survey(2003) and Lee Ji Jung's survey(2001) was used as a reference. Yoon Ho Yul's five grade stress barometer(1996) was also used to measure the amount of stress. The collected data was analyzed by a real number, percentage, the arithmetical mean, the standard deviation, t-test, x²test using SPSS 10.00 for Windows Program. Results are as follow 1. Four to six cups of daily water intake was the highest by 50.0%. Students not have breakfast(55.7%) mostly because they did not have enough time(62.6%). Dinner was the most overeated meal by 72.3% and the most preferred food was meat by 42.0%. In the questions related to exercising, more than half of the students answered that they hardly do not exercise(58%), work out for less than 30minutes(67.3%), and exercised lightly(75.3%). 2. Students were suffering from stresses due to the personal relations(51.36±14.0426), scholastic achievement and personal direction(24.93±8.3037), financial conditions and family matters(20.28±8.1718) and social circumstances(2.7262). 3. In the defection part, the student's reply that they have more than five times of bowel movement on a weekly basis(48.3%), and that it takes three to five minutes to defecate(41.3%) were the highest. More than half of the students answered that their one time excrement quantity was between 30 grams to 60 grams(72.3%) and that it was normal(68.7%). In a question asking how it feels after the defecation(students were allowed to choose more than one answer), relieved and refreshed was the highest by 66.6%, an uncomfortable followed by 42.8%. 4.4% of the students answered that they suffer from strong abdominal pain during the defecation. The rest of the students answered that they do not have stomachache or that it was normal. The students were classified into the constipation group of 103 people(34.9%) and the normal group of 192 people(65.1%) under the devised definition of this research. 4. Students that live in dormitories and do their own cooking were more likely to have constipation than those that live in private residence or in a lodgins. 5. The research showed that there is a mutual relation between water in a day intake and the constipation. It means that the lesser water students drink, the more they suffer from the constipation. The number of times a student had a meal everyday and the constipation was interrelated. If a student had lesser or irregular meals in a day, they had more constipation. Preferred food and constipation was also interrelated. Students that preferred vegetable, fruit, and dairy products were more likely to belong in a normal/general group. 6. By dividing the stress factors into the lower categories, we were able to see that the total stress(t-2.063, p-0.040), personal relations(t-2.316, p-0.021), scholastic achievements and personal directions(t-20127, p-0.034) had mutual relation with the constipation. The constipation group(120.27±30.2708) was suffering from stronger level of stress than the normal group(112.97±28.1466). Through this study, we were able to verify that the few general traits, habitual life, and stress of the women's university students have mutual relations with the constipation.

본 연구의 목적은 뇌졸중 환자의 재활을 위하여 불안정 지지면을 이용한 운동 프로그램이 균형 능력과 운동 기능 능력에 미치는 효과를 알아보고자 실시하였다. 불안정 지지면의 이용한 치료는 임상적으로 뇌졸중으로 인한 편마비 환자뿐만 아니라 스포츠 손상 및 노인들의 질환 등 다양한 병인을 가진 환자들의 치료에 이용되고 있다. 대부분의 뇌졸중 환자들은 재활 훈련을 할 수 있는 병원이나 기관에서 치료를 받을 때에 지지면의 차이를 제공함으로써 보다 더 안정한 지지면에서 적응할 수 있는 방법이 요구되고 있다. 하지만, 아직도 불안정 지지면을 이용한 구체화된 치료적 운동 방법과 객관적 평가에 대한 연구가 미비한 실정이다. 이러한 문제점을 해결하기 위하여 최근 뇌졸중 환자의 불안정 지지면과 이론적 근거를 바탕으로 한 운동 프로그램에 대한 연구가 더욱 필요하다. 본 연구에서는 실험군과 대조군이 같은 운동 프로그램을 적용하였을 때, 두 그룹 간에서 나타나는 균형 향상과 운동 기능 향상에 어떠한 효과를 주는지 살펴보고자 하였다. The purpose of this article was to study the effect of the exercise programme that uses the unstable supporting surface to rehabilitate cerebrovascular patients on balance ability and exercise function ability. The therapy is being clinically used for the patients with diverse pathological factors such as hemiplegia caused by CVA, sports injury, and diseases in the elderly. when most patients with CVA are treated in the hospital or institute that can provide rehabilitation training, they need to be given the way to adjust more stable surpporting surface by being provide with various stages of surface. However, the actual therapeutic exercises is still needed and the study for objective assessments wants conducting. To solve these problems, the study of unstable surface exercise programmes based on the evidences recently need to be made for the patients with CVA. in this study, we intend to look into what effects on the balance improvement and the exercise function are different from the experimental group to the control group with the same programme applied to the two groups.

Purpose: Many university students are under a lot of job-seeking stress because the employment rate is low. This study sought to determine the relationship between job-seeking stress, self esteem, self efficacy and appearance management behavior amongst university students focusing on nursing. Methods: This descriptive correlational study evaluated the relationships between job-seeking stress, self esteem, self efficacy and appearance management behavior of 340 university students was conducted between September 1 and October 5, 2015. Results: The correlational analysis between job-seeking stress, self esteem, self efficacy and appearance management behavior revealed a negative correlation between job-seeking stress, self esteem and self efficacy and a positive correlation between job-seeking stress and appearance management behavior. In addition, age also correlated with self esteem, self efficacy and appearance management behavior. Conclusion: Stress correlated with self esteem and self efficacy and appearance management behavior. Therefore job-seeking stress may be reduced through not only self esteem and self efficacy enhancement programs but also management according to age.

김희재,이혜원,이희수,하종식,이지희 이화여자대학교 의과대학 2003 EMJ (Ewha medical journal) Vol.26 No.2

목적: Src family tyrosine kinases (TK)가 내독소로 인해 유도되는 NF-kB 활성화 신호전달체계에 연관되어 있음이 보고된 바 있다. 또한 내독소(LPS)나 TNF a와 같은 여러 자극제는 IkB-a 의 serine기 또는 tyrosine기의 인산화를 통하여 NF-kB를 활성화 시킨다고 알려진 바 있다. 이에 본 연구에서는 RAW 264.7 대식세포에 내독소 투여 시 유도되는 NF-kB활성화 및 NF-kB 의존성 염증성인자 생성에 대한 Src TK의 역할에 대해 규명하고자 한다. 방법: American Type Culture Collection 에서 구입한 생쥐의 대식세포, RAW264.를 내독소(LPS)에 노출시킨 후 damnacanthal나 PP1을 처리하여, EMSA, Nitrite assay, Western blot을 통하여Src TK가 NF-kB활성과 염증인자의 생성에 있어서 어떤 역할을 하는지에 대하여 조사하였고 내독소 투여로 인한 NF-kB활성에 있어서 Src TK의 기본적인 작용기전에 대해 조사하였다. 결과: Damnacanthal이나 PP1은 Src TK 특이적 억제제로 알려져 있는데, 본 연구에서는 Src TK의 특이적 억제제인 damnacanthal 이나 PP1을 사용하였고, RAW 264.7 대식세포에서 Src TK 특이 억제제의 전처치는 내독소로 유도되는 NF-kB활성을 차단시켰다. 또한 내독소 투여로 증가된 NO 생성은 damnacanthal이나 PP1에 의하여 억제되었다. 이런 TK kinase 억제제는 내독소로 유도되는 serine 기 인산화와 IkB-a 분해를 억제시켰다. 결론: Src kinase 특이적 억제제인 damnacanthal 그리고 PP1이 RAW 264.7세포에서 내독소로 유도되는 NF-kB활성과 Nitric Oxide 생성을 차단시켰다. 또한. Damna-canthal이나 PP1은 내독소로 유도된 serine기 인산화와 IkB-a의 분해를 억제시켰다. Objectives : Src family tyrosine kinases(TK) have been found to be involved in LPS induc-tion of signal cascades. Furthermore Lipopolysaccharide(LPS) or Tumor necrosis factor alpha (TNF-a) activate nuclear transcription factor kB(NF-kB) by inducing serine or tyrosine pho-sphorylation of the inhibitory subunit of NF-k B(I k B- a). In this study, it is our purpose to search the role of Src TK in LPS induced activation of NF-k B and NF-k B dependent induced inflam-matory factors. Methods : Nuclear extracts were prepared from RAW 264.7 cells pretreated with damnacan-thal or PP1 and then stimulate with LPS. After that, we figured out the dffects of inhibition of Src family kinases on LPS-induced activation of NF-kB by EMSA. We investigated effects of damnacanthal of PP1 on the production of NO by Griess assay and LPS-induced serine phos-phorylation and degradation of Ik B-a by Western blots in LPS-stimulated RAW263.7 cells. Results : Inhibition of Src TK with damnacanthal or PP1 blocked LPS-induced NF-kB acti-vation at the range of nanomolar concentrations. Substantial inhibition in LPS-induced production of NO was also observed in cells treated with damnacanthal or PP1. These kinase inhibitors blocked LPS-induced the serine phosphorylation, and the degradation of Ik B-a. Conclusion : we investigated the role of Src TK in NF-k B activation and production of nitric oxide (NO) in LPS stimulated RAW 264.7 macrophages and the underlying mechanism by which Src TK play a role in LPS-induction of the possible pathways leading to NF-k B activation. Src kinase specific inhibitors, damnacanthal and PP1 blocked LPS induced activating NF-k B and producing Nitric Oxide in Raw 264.7 machrophages. Moreover, Damnacanthal and PP1 inhibited LPS induced serine phosphorylation and degradation of Ik B-a.

The old edentulous patients experience xerostomia commonly. They have considerable difficulty in wearing tissue-supported prosthesis and high risk rate of caries. One of them is Sj□gren's syndrome patient. Sj□gren's syndrome is a chronic inflammatory autoimmune disorder that results in a lymphocyte-mediated destruction of exocrine glands. We planned to place implants immediately after extraction in this case of autoimmune disease. The advantages of immediate implant placement include considerable decrease in time from tooth extraction to placement of the final prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plan. We present a case of Sj□gren's syndrome patient treated with immediate implant placement & immediate loading in anterior region and immediate implant placement in posterior region.
