Trail and campground deteriorations and their environmental changes of soil and vegetation were studied in Tonghwa -Sa district of Mt. Palgong Natural Park through 1988 into 1989. The results are summarized as follows : 1. The bare width of trail as one of the trail condition factor was significantly greater on the more heavily used trail. Deterioration types of trail which had higher frequency for a total of 45 observations were rock exposure(42%), trail deepening(40%) and root exposure(18%) in the high order. And also sound type on which the trail was not deteriorated at all amounted to 33% of all observations. 2. Ecological changes of soil and vegatation of trailsides were not found at a uniform tendency except that soil hardness was slightly decreased from trail edge to the forest, but they could be grouped by the type of user\`s behavior and site conditions. Use impacts on the natural environment of trailside in Mt. Palgong are still far from the severe harmulness. 3. Worse damages to compground condition were appeared in Bawi-gol than Susu-gol campsite. Types of mechanically damaged trees were tree with exposed root(63% ), scared tree(43% ), mutilated tree(30 % ) and felled tree in highly frequent order. And diameter increments of trees in campsites were oppressed by the campers. 4. Tree damage types and their frequencies could be basic as a means of which grasp the bounds of user's impacts. User's disturbance on campsite extended to the distance of 70∼90m from the core of campsite at Pawi-gol and 20∼30m at Susu-gol respectively. As the tolerant trees to use impact, Lespedeza maximowiczii, Rhus trichocarpa, Acer palmatum, Rubus crataegifolius and Celastrus orbiculatus were considered.

The $76^{th}$ National Treasure is consisted of seven volumes of Nanjung Ilgi (War Diary of Admiral Yi Sun-sin; each titled by the author based on the zodiac name of the year covered, i.e. Imjin Ilgi, Gyesa Ilgi, Gabo Ilgi, Byeongsin Ilgi, Jeongyu Ilgi, Sok Jeongyu Ilgi, Musul Ilgi), Seogancheob (Letters of Admiral Yi) and Imjin Jangcho (Drafts of Imjin War Reports of Admiral Yi). These are currently in the custody of Hyeonchungsa shrine, the state-managed memorial shrine of Admiral Yi, and has been added to UNESCO's Memory of the World Register in June 2013 in the appreciation of its historical and academic importance as a commander's hand-written battlefield accounts during Japanese invasions of Korea. Imjin Jangcho, among these nine volumes, is a record of battles, including observations on the enemy fleets, suggestions on naval matters, battle expenditure, and methods of battle preparation, transcribed by someone else according to Admiral Yi's instructions. It is Admiral Yi's honest detailobservations on the war situation during Japanese invasions of Korea from 1592 as a Naval Commander of Left Jeolla Province, till 1594 (Year 27 of King Seonjo's reign) as a Commander-in-Chief of the Naval Forces of the South. It is a draft of the war report to be submitted to the King in a single volume as a folio (each sheet folded once to produce one leaf) bound in a side-stitched binding with five holes and inner binding of twisted paper. This study explores the condition and the treatment performed on Imjin Jangcho which could have an implication for the conservation of cultural assets on paper of late Joseon Dynasty.

Objectives : The purpose of this study is to determine whether there is a significant difference in the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio according to the history of suicide attempt in patients with psychiatric diseases. Methods : A medical record review was conducted on patients who had been hospitalized in Konyang University Hospital since 2021-03-01 to 2023-02-28 to collect demographic and clinical characteristics. T-test for continuous variables and Chi-square test for categorical variables were performed to determine demographic differences according to the history of suicide attempt, and the ANCOVA test was performed to compare the average value of peripheral inflammatory marker according to the history of suicide attempt with gender and age as covariates. One-way variance analysis was performed to determine whether the number of suicide attempt causes significant difference of the peripheral inflammatory marker. Results : The final analysis target of this study was 266 patients, 101 had history of suicide attempt, and 165 had no history of suicide attempt. The neutrophil-to-lymphocyte ratio (p<0.001) and platelet-to-lymphocyte ratio (p<0.001) were higher in patients with the history of suicide attempt than patients without the history of suicide attempt, but the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were not significantly increased depending on the serial increase of number of suicide attempts. Conclusions : This study suggests that peripheral inflammatory markers are meaningful and easily accessible indicators for predicting the risk of suicide attempt in psychiatric patients. We expect that prospective follow-up study will be conducted with more subjects and controlled potential confounding variables.

This study is to present a improvement directions for the protection of industrial key technology. For the purpose of the study, the survey was carried out on the administrative security activity of 68 enterprises including Large companies, small-midium companies and public corporations. survey result on the 10 items of security policy, 10 items of personal management and 7 items of the assets management are as follows; First, stable foundation for the efficient implement of security policy is needed. Carrying a security policy into practice and continuous upgrade should be fulfilled with drawing-up of the policy. Also for the vitalization of security activity, arrangement of security organization and security manager are needed with mutual assistance in the company. Periodic security inspection should be practiced for the improvement of security level and security understanding. Second, the increase of investment for security job is needed for security invigoration. Securing cooperation channel with professional security facility such as National Intelligence Service, Korea internet & security agency, Information security consulting company, security research institute is needed, also security outsourcing could be considered as the method of above investment. Especially small-midium company is very vulnerable compared with Large company and public corporation in security management, so increase of government's budget for security support system is necessary. Third, human resource management is important, because the main cause of leak of confidential information is person. Regular education rate for new employee and staff members is relatively high, but the vitalization of security oath for staff members and the third party who access to key technology is necessary. Also access right to key information should be changed whenever access right changes. Reinforcement of management of resigned person such as security oath, the elimination of access right to key information and the deletion of account. is needed. Forth, the control and management of important asset including patent and design should be tightened. Classification of importance of asset and periodic inspection are necessary with the effects evaluation of leak of asset.

1957년에 서명된 로마조약(條約)을 처음 개정한 단일(單一)유럽법(法)이 1987년 7월 1일에 발효(發效)되었을 때 유럽공동체(共同體) 12개 회원국(會員國)들은 공동정책(共同政策)에 의거 상업(商業), 농업(農業), 운송(運送), 금융(金融) 및 기타 관련부분에 있어 단일역내시장(單一域內市場)을 형성하기로 약속했다. 물론 완전한 역내공동시장(域內共同市場)은 자유로운 운송시장(運送市場)을 전제로 한다. 따라서 EC조약(條約)은 모든 회원국(會員國)들이 서어비스의 자유에 근거하여 공동운송정책(共同運送政策)을 따를 것을 강제하고 있다. 항공운송(航空運送)에 있어서의 목표도 역시 다른 모든 경제활동의 목표와 마찬가지로 로마조약(條約)이 적용되는 공동운송정책(共同運送政策)의 일부를 구성하고 있다. 종합적인 공동체항공정책(共同體航空政策)의 작업에는 운임(運賃), 공급량(供給量), 시장진출(市場進出) 및 경쟁상(競爭上)의 일괄적인 자유화 조치 이상의 것을 내포하고 있다. 그것은 국가장벽으로 방해되지 않는 공동체(共同體)의 항공운송망(航空運送網)의 개발과 확장뿐만 아니라 경제(經濟), 안전(安全), 환경(環境) 및 사회적(社會的) 요인(要因)들 간에 합리적인 균형을 이루는 공동체항공운송정책(共同體航空運送政策)의 개발을 위한 공동항공운송정책(共同航空運送政策)의 공식화(公式化)를 요한다. 1987년의 항공(航空)에 관한 일괄입법조치, 1989년의 제 2 차 항공(航空)에 관한 일괄입법조치 및 1992년 이후로 예정된 제 3 차 일괄입법조치에 따라 EC는 초국가적(超國家的)인 항공운송(航空運送) 분야에 있어서의 개방적인 국제경쟁(國際競爭)을 본격적으로 추구하고 있다. 결국 이러한 일괄규칙은 EC와 제(第) 3 국(國)들간의 관계에 중대한 의미를 가지게 될 것이다. EC항공운송정책(航空運送政策)이 아시아 항공산업(航空産業)의 상업운선(商業運船)에 어떠한 영향을 미칠 것인가는 모든 아시아 국가들이 알아야 할 중요한 문제이다. 이론적으로 말해서, 역내공동체(域內共同體) 항공운송(航空運送)의 자유화는 아시아 국가들에 대한 치외법권적(治外法權的) 효과를 일으킬 수 있는 로마조약(條約)과 유럽사법재판소(司法裁判所)에 의해 형성된 원칙들에 필연적으로 영향을 미칠 것이다. 이와 관련하여 아시아 항공산업(航空産業)은 무차별원칙(無差別原則), 설립(設立)의 자유(自由), 서어비스의 자유(自由) 및 EEC 경쟁법(競爭法)과 같은 제(第) 3 국(國)의 국제항공운송에 영향을 미치는 일련의 새로운 원칙과 법률의 출현에 큰 관심을 갖고 있다. 실무적인 관점에서, 1992년 이후의 종합적인 공동체항공운송정책(共同體航空運送政策)의 작업에는 항공운화(航空運貨), 시장진출(市場進出), 제(第)3 및 제(第)4의 운륜자유권(運輪自由權), 복수지정(複數指定), 제(第)5의 자유(自由), 캐보타지(cabotage), 손상(損傷)(derogation), 공급량(供給量), 편수(便數), 불정기운항(不定期運航) 및 기타 부문항공기소음(部門航空機騷音), 최저(最低) 안전(安全) 및 사회적(社會的) 조치(措置), 항공종사자면허(航空從事者免許), 감항증명(堪航證明), 운항시간제도(運航時間制度), 컴퓨터 예약제도(豫約制度), 탑승거절보상의 공동최저기준(共同最低基準), 공중혼잡(空中混雜), 공항이착륙시간할당법(空港離着陸時間割當法), 공항시설(空港施設), 정부지원(政府支援 등). 이와 같은 모든 공동체항공운송정책(共同體航空運送政策)의 주요문제들은 아시아 항공산업(航空産業)에 여러 각도로 영향을 미치게 될 것이다. 위와 같은 문제들 가운데, 제(第) 3국(國) 항공사(航空社)들의 역내공동체(域內共同體) 항로(航路)의 접근, 공급량(供給量), 운임(運賃), 제(第)5의 자유(自由) 및 캐보타지가 아시아 항공산업(航空産業)에 관심이 큰 문제가 되고 있다. 아시아 항공사(航空社)들의 EEC시장(市場)에로의 상업운항(商業運航)이 다소 영향을 받게 될 것이다. 첫째, 복수(複數) 목적지(目的地) 문제이다. 둘째, 항공(航空)서어비스의 운임(運賃) 및 료솔(料率)문제이다. 셋째, 항공운송구역(航空運送區域)에서의 사업에 대한 경쟁원칙의 적용 문제이다. 넷째, 제(第)5 자유(自由) 운륜권(運輪權) 문제이다. 다섯째, 캐보타지(cabotage)문제이다. 끝으로, 유럽 항공사(航空社)들간의 합병(合倂)의 문제이다. 결론적으로 유럽공동체항공운송(共同體航空運送)의 자유화는 1993년까지 공동체(共同體) 역내(域內)와 역외(域外)의 항공운송법제(航空運送法制)의 현재의 모습을 극적으로 바꾸어 놓을 정도로 가속화(加速化)되고 있다. 한편 항공운송(航空運送)의 자유화(自由化)에 대한 EC의 제의는 대담하고 급진적이다. 반면에 그것이 아시아 항공산업(航空産業)에 미칠 영향 또한 중대하다. 의심할 여지없이 항공사(航空社)와 고객들의 이익면에서 EEC와 비(非)EEC국가들의 항공운송산업(航空運送産業)에서 더욱 경제적으로 경쟁적이 되도록 할 필요가 있다. 전세계 항공운송산업(航空運送産業) 운영(運營)의 대부분을 정부가 소유하거나 통제하는 것은 정말로 국제항공운송(國際航空運送)의 발전에 불필요한 장애를 일으킨다. 따라서 國內航空社와 전세계 항공사(航空社)들간의 이해관계의 조화를 협상하는 것이 중요하다. 아마도 아시아 항공사(航空社)들간의 지역적 협조가 미국(美國)뿐만 아니라 유럽으로 부터의 압력 증가에 대해 균형을 이루는 힘이 될 수 있을 것이다.

Purpose : The aim of this study was to examine whether hypercapnia during the first seven days of life was associated with severe intraventricular hemorrhage (IVH) in preterm infants requiring mechanical ventilation. Methods : A matched pair analysis was performed for 19 preterm infants with severe IVH(grade$\geq$3) and 38 infants with no severe IVH (normal or grade 1), who required mechanical ventilation for more than seven days. The univariate and multivariate analysis of severe IVH with maximal and minimal $PaCO_2$, averag $PaCO_2$, SD of $PaCO_2$, and difference in the $PaCO_2$ were assessed. The major perinatal factors and maximal ventilator index (VI) were also compared. Results : Infants with severe IVH had a higher maximal $PaCO_2$ (86.1$\pm$18.4 mmHg vs. 60.1$\pm$ 11.6 mmHg, P <0.001) and mean $PaCO_2$ (47.5$\pm$5.6 mmHg vs. 41.2$\pm$6.3 mmHg, P=0.004) and a larger SD or difference in $PaCO_2$ (14.0$\pm$4.4 mmHg vs. 9.0$\pm$2.4 mmHg; 60.3$\pm$20.9 mmHg vs. 35.5$\pm$11.8 mmHg, P <0.001). However the minimal $PaCO_2$ values did not differ between the groups. Disseminated intravascular coagulation, pulmonary hemorrhage, and the air leak syndrome were more frequent in the IVH group than in the controls. The maximal VI on each day was higher in the IVH group. The multivariate logistic regression analysis after controlling for bleeding tendency showed that the air leak syndrome, maximal VI, and maximal $PaCO_2$ were independently associated with severe IVH [OR, 1.324 (95% CI, 1.011-1.733; P=0.041)]. Conclusion : Extreme hypercapnia was significantly associated with severe IVH in preterm infants, after adjustment for major perinatal risk factors. Frequent monitoring of the $PaCO_2$ may be important for early detection of inadvertent hypercapnia and prompt correction of high PaCOS levels.

Background: In January 2018, revised elderly fixed outpatient copayment for the elderly were implemented. When people ages 65 years and older receive outpatient treatment at clinic-level medical institutions (clinic, dental clinic, Korean medicine clinic), with medical expenses exceeding 15,000 won but not exceeding 25,000 won, their copayment rates have decreased differentially from 30%. This study aimed to examine the changes of health utilization of elderly after revised elderly fixed outpatient copayment. Methods: We used Korea health panel data from 2016 to 2018. The time period is divided into before and after the revised elderly fixed outpatient copayment. We conducted Poisson segmented regression to estimate the changes in outpatient utilization and inpatient utilization and conducted segmented regression to estimate the changes in medical expenses. Results: Immediately after the revised policy, the number of clinic and Korean medicine outpatient visits of medical expenses under 15,000 won decreased. But the number of clinic outpatient visits in the range of 15,000 to 20,000 won and Korean medicine clinic in the range of 20,000 to 25,000 won increased. Copayment in outpatient temporarily decreased. The inpatient admission rates and total medical expenses temporarily decreased but increased again. Conclusion: We confirmed the temporary increase in outpatient utilization in the medical expense segment with reduced copayment rates. And a temporary decrease in medical expenses followed by an increase again. To reduce the burden of medical expense among elderly in the long run, efforts to establish chronic disease management policies aimed at preventing disease occurrence and deterioration in advance need to continue.

Domestic laws such as Korea Marine Pollution Prevention Law (KMPPL) which has been mae and amended according to the conclusions and amendments of various international conventions for the prevention a marine pollution such as MARPOL 73/78 were reviewed and compared with the major contents of the relevant international conventions. Alternative measures for legislating new laws or amending existing laws such as KMPPL for the acceptance of major contents of existing international conventions were proposed. Annex VI of MARPOL 73/78 into which the regulations for the prevention of air pollution from ship have been adopted has been recently accepted in KMPPL which should be applied to ships which are the moving sources of air pollution at sea rather tlnn in Korea Air Environment Conservation Law which should be applied to automobiles and industrial installations in land. The major contents of LC 72/95 have been accepted in KMPPL However, a few of substances requiring special care in Annex II of 72LC, a few of items in characteristics and composition for the matter in relation to criteria governing the issue of permits for the dumping of matter at sea in Annex III of 72LC, and a few of items in wastes or other matter that may be considered for dumping in Annex I of 96 Protocol have not been accepted in KMPPL yet. The major contents of OPRC 90 have been accepted in KMPPL. However, oil pollution emergency plans for sea ports and oil handling facilities, and national contingency plan for preparedness and response have not been accepted in KMPPL yet. The waste oil related articles if Basel Convention, which shall regulate and prohibit transboundary movement of hazardous waste, should be accepted in KMPPL in order to prevent the transfer if scrap-purpose tanker ships containing oil/water mixtures and chemicals remained on beard from advanced countries to developing and/or underdeveloped countries. International Convention for the Control if Harmful Anti-Fouling Systems on the Ships should be accepted in KMPPL rather tlnn in Korea Noxious Chemicals Management Law. International Convention for Ship's Ballast Water/Sediment Management should be accepted in KMPPL or by a new law in order to prevent domestic marine ecosystem and costal environment from the invasion of harmful exotic species through the discharge of ship's ballast water.
