BACKGROUND: This study used MDS-HC 2.0 (Minimum Data Set-Home Care) to analyze the health and the state of function of the traveling health objects. This study was intended to make use of it with the basic materials for providing them with traveling health service suited for the requirement on the health of the traveling health objects. METHODS: The subjects of this study were 1160 people (over 65 years) living under management control of local Health Center from September 7th to October 3th, 2006. This study was analyzed with inter RAI program & SPSS/WIN 10.0, chi-square -test, t-test, and ANOVA. RESULTS: The result showed that 8.97 CAPs per an elderly person was identified and the subjects over 60% had an injury problem from a fall, health prevention service, vision, IADL, pain, and cognition. The number of CAPs in general was high in higher age and the less educated, and those without a job. But, in subjects that had a life partner and a spouse, the number of CAPs was low. In CAPs by the distinction of sex, CAPs which was much more in man than women in statistics were the improvement of health, the abuse of alcohol and drinking wine, bedsore, and the weak supply system. CAPs which women had much more were the function of the heart and the lungs, pain, the performance of the doctor's advice, health prevention service, and incontinence of urine and insertion of catheter. According to the results comparing CAPs by the level of the ADL, the number of CAPs was shown that the group of ADL 2 was higher than group ADL 1. The matter in which the traveling health service had to be applied in all both ADL1 and ADL2 was injury from a fall, health prevention service, and vision. Conculsion: MDS-HC is applicable to decide the care needs for health and social service supplies. The results can be further applicable for careplan, and referral criteria in continuum of care service over long-term care spectrums.

We examined the expressions of CD44 splice variants (v4/5, v6), alpha-smooth muscle actin, nm23 to evaluate their roles as prognostic factors in 70 cases of uterine cervical carcinoma (stage IB to IIB) who were surgically treated from January 1989 to June 1990 with a clinical follow-up of a minimum of 5 years. The expression was examined by an immunohistochemical method using archival formalin fixed paraffin embedded tissue. In the 70 cases, 61 cases were squamous cell carcinoma and 9 cases were adenocarcinoma. CD44v4/5, CD44v6, alpha-smooth muscle actin, and nm23 were detected in 41.4%, 70%, 100%, and 74.3% of tumor samples, respectively. CD44 splice variants and nm23 showed membrane and cytoplasmic staining of tumor cells, respectively. The expression of alpha-smooth muscle actin showed cytoplasmic staining confined to stromal cells and was classified into three grades by the extent in stromal cells: with less than 10% of stromal cells; 32.9%, 10-50% of stromal cells; 40.0%, more than 50%; 27.1%. These expressions were not correlated with histologic types, lymph node involvement, recurrence, and grades of tumor infiltrating lymphocyte (TIL). But CD44v4/5 had significantly inverse correlation with TIL (p=0.049). The expression of CD44v4/5 was significantly correlated with that of CD44v6 (p=0.05), and that of alpha-smooth muscle actin was inversely correlated with that of nm23 (p=0.049). In conclusion, in FIGO IB-IIB uterine cervical carcinoma CD44 variants, nm23, and SMA show high prevalence, however, with little prognostic significance assessed by recurrence and lymph node metastasis.

4.Measurement of Inter-Rater Reliability in Systematic Review.
Hanyang Medical Reviews 2015;35(1):44-49
Inter-rater reliability refers to the degree of agreement when a measurement is repeated under identical conditions by different raters. In systematic review, it can be used to evaluate agreement between authors in the process of extracting data. While there have been a variety of methods to measure inter-rater reliability, percent agreement and Cohen's kappa are commonly used in the categorical data. Percent agreement is an amount of actually observed agreement. While the calculation is simple, it has a limitation in that the effect of chance in achieving agreement between raters is not accounted for. Cohen's kappa is a more robust method than percent agreement since it is an adjusted agreement considering the effect of chance. The interpretation of kappa can be misled, because it is sensitive to the distribution of data. Therefore, it is desirable to present both values of percent agreement and kappa in the review. If the value of kappa is too low in spite of high observed agreement, alternative statistics can be pursued.

OBJECTIVE: Many amputees do not use their prostheses consistently because of the unhelpfulness or discomfort. In this point, this survey was to assess the prosthetic problems in their function and willingness to use. METHOD: We investigated the 18 burn induced upper extremity amputees of Hankang Sacred Heart Hospital Burn Center with the questionnaire or interview. RESULTS: The mean age was 39.6 years at the time of amputation & 43.3 years at the time of survey. Their amputation levels were composed of 72.2% of below elbow and 27.8% of above elbow. The using time of prosthesis was revealed that 'all day long' use in 50%, 'going out' use in 33.3% and 'living activity' use in 11.1%. Their complaint for prosthetic problems were discoloration (38.9%), poor appearance (27.8%), sweating (27.8%) and inadequate function (22.2%). Considerable number of them suffered from residual burn wound or scar in contact with a socket (27.8%) and itching and tingling sensation (22.2%). Employment was not accomplished in 61.1% of the amputees. CONCLUSION: The information thus obtained in this investigation would be expected to be helpful in the prosthetic prescription and rehabilitation training of upper extremity amputees for their welfare.

Korean Journal of Gastrointestinal Endoscopy 2010;40(3):145-156
Because screening gastrointestinal endoscopies have been widely performed recently, diagnosis rates of early stage cancer have been increasing rapidly. This trend has also led to advances in therapeutic endoscopy, which is less invasive than surgery. The state-of-the-art technique, endoscopic submucosal dissection (ESD), allows more favorable outcomes than conventional endoscopic mucosal resection (EMR) regarding en-bloc resection of the lesion, irrespective of the size of the lesion. ESD has already been established as the standard therapeutic option for neoplastic lesions in the upper gastrointestinal tract. However, the use of ESD for colorectal lesions is not yet established because of the unique pathological, organ specific characteristics of colonic lesions. Moreover, endoscopists are required to have higher qualifications to perform ESD and tend to cause complications more frequently. Nevertheless, it is obvious that ESD has a therapeutic advantage for certain colonic lesions and enables endoscopists to achieve a higher en-bloc resection rate, resulting in enhanced curability and more accurate histopathological assessment. Recent development of a special colonoscope for ESD and refinement of devices such as surgical knives and traction systems are expected to overcome some limitations of ESD and a standard protocol will be available in the near future. In this review, we will discuss the current status and future prospects of colorectal ESD.

Somatosensory evoked potentials(SSEP's) are commonly employed to monitor cerebral and spinal cord function in patients with various lesions in the nervous system. In this study, we evaluated SSEP's as a means of measuring not only neurophysiological function but also the alteration of blood folw in the territory of cerebral ischemia. We examined SSEP's and regional cerebral blood flow(rCBF) in the bilateral suprasy1vian gyri following unilateral middle cerebral artery(MCA) occlusion in 15 cats(Group II). The duration of arterial occlusion was 30 minutes followed by 1 hour of recirculation. Five additional cats served as sham-operated groups(Group I). The animals in Group II were divided into 2 subgroups according to the change of the observed rCBF in the ipsilateral hemisphere. Immediately after MCA occlusion, rCBF decreased from around 50 to 14mg/100g/min. Decreased rCBF was remained below 20ml/100g/min throughout the ischemic period in 6 cats(Group IIb), and in the remaining 9 cats, the decreased rCBF was increasing during ischemia although the blood flow was subnormal(Group IIa). The recovery of rCBF during recirculation was faster in Group IIa than in Group IIb. In Group IIa and IIb, there was a significant slowing of the interpeak latency between dorsal column nuclei(Fz) and the major negative deflection(MN) (P<0.05) in the ipsilateral hemisphere and a precipitous decrease in the amplitude of the ipsilateral P1-MN complex immediately after occlusion(P<0.05). In Group IIb the suppressed SSEP's did not show any recovery during ischemia, and recovered late during recirculation. In Group IIa the suppressed SSEP's tended to recover during recirculation. In Group IIa the suppressed SSEP's tended to recover during ischemia and recovered early during recirculation. SSEP's were not completely abolished throughout the experiment in any experimental grup. The relationship between the changes in rCBF and amplitude of SSEP's in the ipsilateral hemisphere was significant(r=0.943, P<0.05) during occlusion of the middle cerebral artery in Group IIa. However there was not any other relationship in the other groups or among other wave components. These results indicate that the suppression of SSEP's and their failure to recover during focal cerebral ischemia correlate with the lack of collateral circulation. Furthermore, SSEP's can be useful means to evaluate the reversibility of cerebral ischemia, which may be decided by existence of collateral circulation. And it appers that the time threshold for abolition of SSEP's is more than 30 minutes in focal cerebral ischemia in the cat.

Journal of Periodontal & Implant Science 2014;44(3):147-155
PURPOSE: In the anterior maxilla, hard and soft tissue augmentations are sometimes required to meet esthetic and functional demands. In such cases, primary soft tissue closure after bone grafting procedures is indispensable for a successful outcome. This report describes a simple method for soft tissue coverage of a guided bone regeneration (GBR) site using the double-rotated palatal subepithelial connective tissue graft (RPSCTG) technique for a maxillary anterior defect. METHODS: We present a 60-year-old man with a defect in the anterior maxilla requiring hard and soft tissue augmentations. The bone graft materials were filled above the alveolar defect and a titanium-reinforced nonresorbable membrane was placed to cover the graft materials. We used the RPSCTG technique to achieve primary soft tissue closure over the graft materials and the barrier membrane. Additional soft tissue augmentation using a contralateral RPSCTG and membrane removal were simultaneously performed 7 weeks after the stage 1 surgery to establish more abundant soft tissue architecture. RESULTS: Flap necrosis occurred after the stage 1 surgery. Signs of infection or suppuration were not observed in the donor or recipient sites after the stage 2 surgery. These procedures enhanced the alveolar ridge volume, increased the amount of keratinized tissue, and improved the esthetic profile for restorative treatment. CONCLUSIONS: The use of RPSCTG could assist the soft tissue closure of the GBR sites because it provides sufficient soft tissue thickness, an ample vascular supply, protection of anatomical structures, and patient comfort. The treatment outcome was acceptable, despite membrane exposure, and the RPSCTG allowed for vitalization and harmonization with the recipient tissue.
