This study investigates the impact of International Monetary Fund(IMF) Age on the household behavior of food consumption and analysis the related factors(demographic variables, family life style) to find out the reasonable consumer's consciousness and food market conditions. The results are as follows. 1. General life style and food life style, considered as family life style, were classified into 7 types and 9 types respectively as family life style by factor analysis. 2. The rationality of using and disposing stage on food life has increased, the rationality of the planning stage on food life has decreased since the IMF age began. But the rationality of overall food consumption has hardly changed. 3. The amount of purchasing was decreased, discount store was favorite place to buy food, and safety and freshness were major determinants in purchasing for most of food items. But this was different with food items. The various information sources were used impartially to buy food, cash was used mainly, and the degree of using the discount ticket/coupon was a little low. 4. Income level is an influential factor on the rationality of the planning and purchasing stage on food life, while environment-oriented food life style has influenced on the rationality of using and disposing stage. The purchasing amount of grain products, meats, milk products, bread and snacks, drinks, alcoholic drinks, water and convenience goods has influenced by demographic variables, eating out had been influenced by general life styles, and fruits, healthy foods, processed foodstuffs, favorite foods, vegetables seaweeds, import foods and seafood had been mainly influenced by food life style since IMF age began.

Purpose: Nowadays the Korean society is in the center of time of the social change. Because of dissociation of traditional family, IMF (International Monetary Fund) crisis and economic recession, the mortality rate of suicidal attempts are increasing annually. The majority of suicidal attempts were by poisoning considering the characteristics of korean society. Therefore we studied to find out the characteristics of suicidal poisoning before and after social economic stress, and to suggest the direction for the proper management. Methods: We reviewed medical records of 547 patients of suicide by poisoning who visited the emergency medical centers of St. Mary's hospitals from 1997 to 2004. For the annual trends analysis, we analyzed the demographic and toxicologic data of these patients compared with before and after IMF crisis (1998) and the economic recession ($2003\~2004$). Results: At the time of IMF and the economic recession, the number of suicidal poisoning increased, especially in fifth decade. The refusal rate of toxicological emergency treatment increased. Also the mortality rate and the admission rate to ICU (Intensive Care Unit) increased during the same period. In the result of the comparison analysis, clinical severity and mortality of social problem group were higher. However they couldn't be treated appropriately because of financial problem and the family indifference. Conclusion: At the economic recession period, the severity of suicidal poisoned patients was high. But the refusal rate of toxicologic treatment also increased, so the patients had lost the chance for proper toxicologic treatment. Therefore they would be supported by medical institution and public health.

Typical surgical methods for the treatment of mandibular fractures include intermaxillary-fixation (IMF) for obtaining temporary intraoperative occlusion. Traditionally IMF has been achieved with arch-bars or interdental eyelet wiring. However, these techniques are time-consuming procedures, can produce periodontal damage, and are not well tolerated by the patient even under local anesthesia. Moreover, daily maintenance of oral hygiene is difficult for patients with an arch bar. Recently, intermaxillary fixation using intraoral skeletal anchorage screws (SAS) has been introduced for the treatment of mandibular fractures. This method solves the problems above, but they have the potential for tooth damage, screw fractures and intraoperative occlusal instability. In this study, patients with mandiblular fractures were divided into three groups. Group 1 was treated by IMF using archbars(both maxilla and mandible), Group 2 was treated with SAS(maxilla) and arch-bar (mandible), Group 3 was treated with SAS(both maxilla and mandible). The aim of this study was to evaluate the influence of the different IMF methods on periodontal tissue health and intraoperative occlusal rehabilitation about each groups, and to discuss the most favorable IMF method.

Objective: The objective of this study was to measure the special expression pattern of lipid metabolism genes and investigate the molecular mechanisms underlying intramuscular fat (IMF) deposition in Longissimus dorsi muscle of Laiwu pigs. Methods: Thirty-six pigs (Laiwu n = 18; Duroc×Landrace×Yorkshire n = 18) were used for the measurement of the backfat thickness, marbling score, IMF content, and expression of lipid metabolism genes. Results: Significant correlations were found between IMF content and the mRNA expression of lipid metabolism genes. Of the 14 fat deposition genes measured, fatty acid synthase (FASN) showed the strongest correlation (r = 0.75, p = 0.001) with IMF content, and of the 6 fat removal genes, carnitine palmitoyl transferase 1B (CPT1B) exhibited the greatest negative correlation (r = -0.66, p = 0.003) with IMF content in Laiwu pig. Multiple regression analysis showed that CPT1B, FASN, solute carrier family 27 member 1 (SLC27A1), and fatty acid binding protein 3 (FABP3) contributed 38% of the prediction value for IMF content in Laiwu pigs. Of these four variables, CPT1B had the greatest contribution to IMF content (14%) followed by FASN (11%), SLC27A1 (9%), and FABP3 (4%). Conclusion: Our results indicate that the combined effects of an upregulation in fat deposition genes and downregulation in fat removal genes promotes IMF deposition in Laiwu pigs.

보일러하면 으레 겨울을 떠올리지만 성수기는 봄과 가을이다. 봄철인 4$\~$5월에는 주택이나 건물의 신$\cdot$증축으로 신규 수요가 많은 반면 가을인 9$\~$11월에는 겨울을 앞두고 노후 보일러를 새 보일러로 바꾸는 교체 수요가 많다. 올해 보일러 시장은 IMF한파 영향으로 인한 건설경기 위축과 이사수요 격감, 일반 가계의 소비 위축, 유가 상승 등으로 침체가 예상된다. 제조업체들은 소위 `IMF형 제품`들을 대거 선보이며 고객 확보에 힘을 쏟고 있다.

우리 앞에 닥친 IMF 경제위기를 극복하기 위해서 온 국민이 창조적으로 연구개발하는 마음으로 생활을 과학화해서 절약할 것은 절약하고 수리할 것은 수리하고 만들 수 있는 것은 만들어 써야한다. 특히 과학기술자들이 투철한 프로의식아래 독창성을 발휘, 과학기술을 진흥시켜 독창적인 신제품을 많이 개발한다면 IMF그늘에서 벗어나는 시기를 크게 앞당길 수 있을 것이다.

한국전쟁 이후 한국의 경제성장은 세계에서 유래가 없을 정도로 급속도로 이루어져 왔다. 연평균 10%에 가까운 경제성장으로 IMF를 맞기 이전에는 1인당 국민소득 1만불을 달성하고 OECD에 가입하여 선진국의 문턱까지 도달하였다. 그러나 IMF로 귀결된 경제적 모순의 누적은 한국경제의 근본적인 성장잠재력에 의심을 갖게 만들었다. 세계화와 환경문제로 대표되는 세계경제 환경의 변화는 생산요소의 대량 투입을 통한 양적 성장을 통해 뒷받침되어온 한국경제의 성장방식에 근본적인 변화를 요구하고 있다. (중략)

In this paper, classification of spall and crack faults of gear teeth is studied by applying the ensemble empirical mode decomposition(EEMD) for the gear transmission error(TE). Finite element models of the gears with the two faults are built, and TE is obtained by simulation of the gears under loaded contact. EEMD is applied to the residuals of the TE which are the difference between the normal and faulty signal. From the result, the difference of spall and crack faults are clearly identified by the intrinsic mode functions(IMF). A simple test bed is installed to illustrate the approach, which consists of motor, brake and a pair of spur gears. Two gears are employed to obtain the TE for the normal, spalled, and cracked gears, and the type of the faults are separated by the same EEMD application process. In order to quantify the results, crest factors are applied to each IMF. Characteristics of spall and crack are well represented by the crest factors of the first and the third IMF, which are used as the feature signals. The classification is carried out using the Bayes decision theory using the feature signals acquired through the experiments.
