The elevation in the standard of living in the modern society brought about the increase of adult disease, above all the Number of patients with diabetes mellitus is world-widely increasing every year. Such a disease is possible to control one's illness or to extend one's life by the steady self-care, however, the lack of the steady self-care is able to result in dangerous complications such as visual disorder, nephropathy, Neuropathy, skin infection, and cardiovascular disease and so on Therefore, the role of nurses that must be knowledge of the diabes Mellitus, select the reasonable methods to the patients and that simultaneously excute a group education and a individual education is very important. Accordingly, this study is intended to develop the effective teaching program for nurses and patients that should continuously execute the self-control for one's life. The effective teaching program of patients with diabetes mellitus is presented as follows: 1. Nurses should instruct the knowledge of the diabetes Mellitus. such as etiology of the diabetes mellitus, pathophysiology, Clinical manifestation, insulin and complications ete. 2. Self-monitoring-Nurses explain the purpose of the urine and blood test, and the exact test method of them to the patients. The regular test is always reguired in the trip and illness, and ketone test are reguired in a glucose plethora. Nurses need to teach the patients as follows:All the tests should be recorded and presented in the hospital:and a reagent should be stored in the place without heat, light, and moisture. 3. Nurses should instruct so that the blood sugar test practice before the meal and bed, and reduce some times a week according to the amount adiustment of insulin, and to the number of the test according to one's stress, level of activities, and illness. 4. The type and the amount of the insulin in planning and praticing the patient's diet shoulf be carefully considered. 5. insulin injection-The nurse need to show the right technique of the injection, the type of insulin, onset, peak, duration, and regular time-that is, injecting at 30∼60 minutes before the meal. It is necessary cloudy insulins are Well-mixed, and It must be emphasized that patients might represent hypoglycemia when injecting the excessive amount and the symptom should be informed to patients. In addition, The nurse need to instruct he rotates the injection sites by the plan. 6. It is necessary to build the regular exercise planning. It is effecient to do walking, cycling and swimming around 3∼4 times a week. It must be taught that the severe exercise might bring about hypoglycemia, and lead to dangerous circumstances. 7. Complication-in order to prevent hypoglycemia, it is important to teach so that have orange juice or candy and take urine test when the first symptom, increase the intake of glucose When long-time exercise, have a snack before bed, know the problems of nausea, vomiting and insulin intake in a situations of ketoacidosis. In order to prevent diabetic coma, It is necessary to teach so that take a insulin injecion and a urine and blood sugar monitoring, visit the hospital in the case of the change of test results and weight, and be careful for an injection and skin disease.

The Transportation Service Index(TSI) is a monthly(quarterly) measures of the volume of services performed by the for-hire transportation sectors; road, railroad, air and maritime mode. In Korea the TSI for domestic transportation modes(except road side transportation modes) is estimated and published quarterly since April, 2006. The objective of this study is to develop and analyze TSI for cross border transportation to extend current TSI. Cross border transport is classified into four sectors: air passenger, maritime passenger, air freight and maritime freight. For each sector, a data collection system was established and a seasonal adjustment model was developed using collected data(traffic volume data from Jan. 1995 to Dec. 2008). Using seasonally adjusted data, the index for each sector was calculated. Passenger index and freight index were calculated by employing the Fisher's ideal index method. The cross border TSI is not likely to be useful in forecasting economic activity in future because the monthly TSI proved to be a lagging index. But the cross border TSI is still useful for transportation planning and decision making: monitoring of transportation service changes, analyzing the effect of the execution of transportation policy and introduction of new transportation system and so on. 교통산업서비스지수는 운임을 받고 수송서비스를 제공하는 교통산업부문의 수송실적을 지수화한 것으로, 타산업부문 및 국가경제활동에 직‧간접적으로 큰 영향을 끼치고 있는 교통산업부문의 활동수준을 대표할 만한 지수가 없다는 인식에서 산정이 시작되었다. 국외에서는 미국과 프랑스, 일본 등에서 지수를 산정․발표하고 있으며, 국내에서는 2005년과 2006년에 수행된 연구를 바탕으로 2006년부터 매 분기별로 교통산업서비스지수가 산정․발표되고 있다. 본 연구에서는 우리나라 교통산업서비스지수 산정 대상 분야를 국제부문으로 확대하기 위해 국제항공여객, 국제해운여객, 국제항공화물, 국제해운화물의 네 가지 세부부문을 지수 산정 대상으로 설정하였다. 각 부문에 대한 기초자료와 계절변동모형의 구축을 통해 세부부문별 지수를 산정하고 가중치의 적용을 통해 국제여객과 국제화물 분야의 지수를 산정하였다. 또한 산정된 국제부문의 교통산업서비스지수에 대해 주요 시계열 변화와 그 원인을 분석하였으며, 통계청의 국내 경기 기준순환일과의 비교를 통해 경기변동과의 연관성 분석을 시행하였다. 분석결과 국제부문 교통산업서비스지수는 전반적으로 국내 경기 변화에 대해 후행성을 갖는 것으로 나타나 경기예측 변수로는 적절하지 않은 것으로 판단되었다. 본 연구를 통해 구축된 국제부문의 지수산정체계와 산정방법은 매 분기별 국내 교통산업서비스지수의 산정에 활용되고 있으며, 국제부문의 교통산업서비스지수는 기존의 국내부문 지수와 함께 국내 교통부문의 단기 변화를 보다 시의성 있고 과학적으로 분석할 수 있는 기초자료가 될 것이다.
