Legislation and enforcement of the Presidential Records Management Law was an important turning point in Korean archival management history. In the past, the notion of presidential records was vague. The law was a starting point of establishing presidential records management. The Presidential Records Management Law provides the definition of presidential records and its scope, and establishes the protection of presidential records through restricted access to the records. The key to the law is to enable a president freely to produce records and transfer them to the next administration without omission. In other words, it aims to stop the practice that presidential records are produced but never be left. But, 'disputes over the release of presidential records' and the disclosing of access-restricted presidential records presented a crisis to national records management as well as the prospect of presidential records management, even if they were 'legal procedures.' The instability of presidential records management could give a serious impact on the national records management and its operation. Amid this situation, it is required to review the presidential records management system and provide recommendations for improvement, even if the enforcement of law has just started. The most urgent things in improving presidential records management are to secure its independence, specialty, and to complement restricted access to presidential records. For securing independency, presidential records management should be done by a separate organization other than the National Archives of Korea while for promoting specialty, a newly established organization could serve as a professional archive. And for complementing restricted access to the presidential records, the access should be more limited. In other words, more discretion is needed in permitting access. And more specific regulations should be applied to the permitted records. However, these regulatory actions may not have effects unless independency is not secured. Thus, more fundamentally, independency of the National Archives of Korea should be first established.
Purpose : Serum squamous cell (SCC) antigen levels were examined in uterine cervix cancer undergoing radiation therapy, and authors analyzed the relationship between SCC antigen levels and treatment results. Materials and Methods :This is a retrospective study of 181 conical carcinoma patients who received radiotherapy and examined serial serum SCC antigen from 1991 to 1997 at Soonchunhyang University Hospital. One hundred and eighteen patients underwent SCC antigen evaluation at diagnosis The relationship between the serum tumor marker level and disease free survival, recurrence pattern, and other prognostic factors were analyzed according to various statistical methods. Results : The Positivity rate (initial serum value above 2.5 ng/ml) was increased with FIGO stage (IB-IIA 57% to IV 91%) and more discriminative than cutoff value of 1.5 ng/ml. Five year disease free survival rates for the stage IB-IIA, IIB, III and IV were 79.2%, 68.7%, 33.4% and 0%, respectively. The 5-year disease free survival rate for patients with serum SCC antigen levels above 5.0 ng/ml was 34% versus 55~62% for patients with normal range (>1.5 ng/ml) or mildly elevated levels (1.5~5.0 ng/ml). Rising SCC antigen levels preceded the clinical detection of disease by a mean of 4.8 months (range 1 ~13 months). Negative linear correlation was observed between initial SCC antigen levels and relapse free survival (r=-0.226), and by multivariate analysis, initial SCC antigen level had a large impact on the relapse free survival. Conclusion : SCC antigen assay is a useful aid to predict the prognosis of squamous cell carcinoma of the uterine cervix and to detect recurrence.
This study aimed to determine the management and environmental factors affecting medical expense reduction. For analysis, medical expenses were divided into hospitalization expenses and outpatient treatment expenses, and the rate of medical expense reduction was classified into initial and final reduction rates. Data were collected through a direct survey among 205 directors of independent health insurance review departments of hospital-level medical institutions in Korea. The results of the study are discussed below: In the analysis, differences in the initial and final reduction rates of hospitalization expenses and outpatient treatment expenses were compared. The results showed that, in hospitalization expenses, the initial and final reduction rates were both significantly affected by the following management factors: number of beds, number of departments, number of personnel reviewing health insurance cases, and total number of employees. Further, in outpatient treatment expenses, the initial and final reduction rates were both affected significantly by the following management factors: management of medical records, number of beds, number of departments, number of personnel reviewing health insurance, and total number of employees. The management factors significantly affecting both the initial and final reduction rates were higher number of beds for hospitalization expenses and electronic medical record management for outpatient treatment expenses. The environmental factors significantly affecting both the initial and final reduction rates of hospitalization expenses were a highly cooperative work environment, better implementation of indicator management systems, and overtime pay. Better implementation of indicator management system and a committee for handling medical expenses had significant effects on the initial reduction rate for outpatient treatment expenses. A highly cooperative work environment, better implementation of indicator management system, and overtime pay had significant effects on the final reduction rate for outpatient treatment expenses.

The purpose of this study was to evaluate the effects of the non-pharmacological intervention on depressive symptoms in the older adults with mild cognitive impairment. A total of 1,147 studies were retrieved from PubMed, CINAHL, PsycINFO, Science direct, KISS, RISS, and DBPia. Twenty-one studies which met the criteria were selected and the quality assessment was conducted independently by two investigators. The effect size of non-pharmacological intervention was estimated using Comprehensive Meta-Analysis 3.0. The overall effect size turned out to be the medium effect size (Hedges' g=-0.68, 95% CI=-1.01~-0.36). As a result of the subgroup analysis, the intervention type was statistically significant. The effect size of cognitive intervention (Hedges' g=-1.03, 95% CI=-1.43~-0.61) and multi component intervention (Hedges' g=-0.97, 95% CI=-1.63~-0.33) was greater than excise intervention (Hedges' g=-0.53, 95% CI=-1.16~0.03). This study shows that non-pharmacological intervention was also effective in reducing depressive symptoms in the older adults with mild cognitive impairment. Based on the research results, it is expected that various non-pharmacological intervention studies will be attempted to improve cognitive function and depressive symptoms of the older adults with mild cognitive impairment.

Purpose: This study was to investigate the dentists' experience and awareness of foreign body ingestion and aspiration during dental prosthetic treatment. Materials and Methods: A survey of 157 dentists working at 108 dental institutions in Daejeon and Chungcheong provinces was carried out and frequency analysis was conducted. Chi-square test was conducted to find out the difference between the sociodemographic data and experience of foreign body ingestion and aspiration of patients and independent sample t-test was conducted to find out the difference in awareness depending on whether receiving related education. Results: The percentage of dentists experiencing dropping foreign body into patients' oral cavity was 99.4% and the percentage of dentists experiencing foreign body ingestion and aspiration of patients was 53.5%. There were more dentists who experienced foreign body ingestion and aspiration of patients in male than female, longer working career, and general practitioners than specialists (P < .05). 50.3% of the respondents received related education. When they receive related education, they had low degree of concern, high confidence in coping with situations, and low willingness to receive education in the future (P < .05). Conclusion: The percentage of foreign body dropping was 16% higher in prosthetic treatment than general treatment. The percentage of dentists with experience of foreign body ingestion and aspiration of patients was 53.5%. Among them, 92.9% experienced foreign body ingestion of patients and 7.1% of them experienced foreign body aspiration of patients.
Based on the perception that integrated retirement preparation in various areas is needed in preparation for increased old age, this study aims to identify the status and characteristics of retirement preparation of middle-aged people and reveal the relationship with successful aging. In addition, it aims to find out the mediating effect of social support in the relationship between retirement preparation and successful aging for the middle-aged. To confirm this, 1,037 men and women aged 50 to 64 who responded to the third, fourth, and fifth additional surveys of the Korean Retirement & Income Study (KReIS) conducted by the National Pension Research Institute were analyzed. When the preparation of middle-aged people for retirement affects successful aging, bootstrapping with IBM SPSS 26 Process Macro Model 4 was conducted to verify the mediating effect of social support. As a result of verifying the significance of independent variables on the parameters, preparation for retirement was positively (+) significant. In other words, it was verified that the higher the preparation for retirement, the higher the social support. Furthermore, it was discovered that social support, an independent variable, had a significant impact on successful aging, and social support, an independent variable, had a significant impact on successful aging. The results of this study suggest the need for social support for successful aging through the preparation of middle-aged people for retirement. It is intended to derive policy implications for preparing for retirement and provide them as basic data to increase the level of successful aging.
Purpose: The primary gastrointestinal non-Hodgkin's lymphoma(GI-NHL) is the most common extranodal NHL. Surgery with postoperative radiotherapy or chemotherapy was tried with some success, but proper management guidelines have not been estabilished in localized GI-NHL due to its rarity and the lack of randomized trials. So we designed this study to evaluate treatment results and the lack of randomized trials. So we designed this study to evaluate treatment results and prognostic factors in localized GI-NHL, and to assess proper treatment mdality after surgical resection accordig to risk factors by survival analysis. Method: Seventy three patients who received surgical resection due to localized GI-NHL from Jan. 1916 to Apr. 1991 were reviewed in this study. Prognostic factors were analyzed by multivariate analysis program including postoperative treatment methods, and treatment results were compared according to prognostic factors and treatment modalities. Results: Overall 5-year survival rate was 62.3%, for all patients. The 5-year survival rate was 80.0% for patients with stage I GI-NHL and 45.7% for those with stage II. Chemotherapy or not, stage and residuum or not after surgical resection were significant independent prognositic factors. Postoperative adjuvant treatments showed significant survival benefit. In patients with high risk factors such as stage II or residuum after surgical resection, postoperative combined chemotherapy and radiotherapy showed better survival than those treated with single modality. Conclusions: Chemothrapy or not, stage, and residuum or not were important prognostic factors of patients with localized GI-NHL after surgical resection. Either chemotherapy or radiation therapy alone after surgical resection is recommanded for patients without high risk factors(stage II or residuum after surgical resection) but the postoperative combined chemotherapy and radiotherapy seems to be beneficial for patients with high risk factors.
In the case of single well pumping tests the storativities are generally overestimated. To compensate these errors, the effective wellbore radius should be introduced as a distance to an imaginary observation well in the time-drawdown analysis. Effective wellbore radius can be calculated through step drawdown tests or using skin factor equation. But both are of trial-and-error methods guessing real storativity values and, therefor, are difficult to apply to the field conditions. An equation was developed to estimate effective wellbore radius from storativity values obtained from pumping well data. For this study, a total of 136 time-drawdown data set were used to derive the equation. The effective wellbore radius were estimated first by changing them till the storativity values obtained from the pumping-well data match the ones based on the observation-well data. Then the equation was regressed from the relation between effective wellbore radius and the storativity values obtained from the pumping-well data. It is believed that the equation would be useful in estimating effective wellbore radius from the single well tests.

The Green Wall system is one of segmental concrete crib type earth retaining wall. Green wall is constructed as procedures that lay the front stretchers, rear stretchers and headers then making a rigid body through harden filled soil of interior cell. Recently, Green Wall method is applied in variable cutting ground construction because of advantage which minimize to cut base ground. In case of Green Wall method is constructed with soil nail method, expect that total system stability will increase more than flexible facing because of facing stiffness is big. However, in this case of design, facing stiffness is not considered so that is poor economy. Hence, in this study, stability increasing effect of total system analyze about that soil nail method is constructed with rigidity facing like a Green Wall method. In present study, laboratory model tests was performed for analysis on stability increasing effect of total system about changing stiffness of facing. LEM analysis conducted for evaluation on safety factor of total system sliding that facing condition changed.
