  • The agricultural industry is beset by continuing demands to decrease the use of pest control agents which employ toxic modes of action. Although there are real problems of pesticide resistance, and sometimes overuse or redistribution in the environment, much criticism results from a lack of appreciation of how small is the risk involved. Whatever the background reasons, research and development for pesticide alternatives, particularly within Integrated Pest Management systems, is clearly of high priority. Currently available approaches, including use of natural products and molecular biology, are often regarded with naive optimism and require critical appraisal. For the future, methods of pest control based on chemicals with non-toxic modes of action (e.g. pheromones) continue to offer promise but, for widespread use, will require their integration with biological agents and development by means of plant molecular biology.

  • Ankle fractures with syndesmotic injuries often require fixation, where metal screw fixation is a popular method. However, as the patient begins weight-bearing, most syndesmotic screws tend to loosen or break, and removal of such screws has been challenging for the surgeons, as the available techniques require predrilling or trephination and are associated with risks of bone damage. This study presents a case with technical tip for the removal of broken tricortical-fixed non-cannulated syndesmotic screws. It implements the generation of a small cortical window in the medial distal tibia and the use of pliers to engage the screw tip and remove through the medial side. The technique presented in the current study overcomes these limitations and facilitates minimal bone damage and reduced exposure to radiation.

  • This study analyzes the buyer's remedies for defects in title under DCFR, and it is compared with those of CISG. DCFR adopts a unitary concept of 'non-performance' which is any failure and includes delayed performance and any other performance which is not conformed with the contract. In terms of defects in title, any remedies for non-performance are available under DCFR. Thus. under DCFR, the buyer is entitled to enforce specific performance of obligations, to withhold performance, to terminate for fundamental non-performance, to reduce price, to damage for loss, to require repair, or to deliver a replacement. But under CISG, whether or not defects in title constitute 'non-conformity' is not clear and the majority understands 'non-conformity' does not include title defects. Therefore, the buyer may not has rights to require repair and delivery of replacement unlike DCFR.

  • Pulmonary arteriovenous malformation (AVM) is a congenital vascular disease in which interventional radiologists can play both diagnostic and therapeutic roles in patient management. The diagnosis of pulmonary AVM is simple and can usually be made based on CT images. Endovascular treatment, that is, selective embolization of the pulmonary artery feeding the nidus of the pulmonary AVM, and/or selectively either the nidus or draining vein, has become a first-line treatment with advances in interventional devices. However, some vascular diseases can simulate pulmonary AVMs on CT and pulmonary angiography. This subset can confuse interventional radiologists and referring physicians. Vascular mimickers of pulmonary AVM have not been widely known and described in detail in the literature, although some of these require surgical correction, while others require regular follow-up. This article reviews the clinical and radiologic features of pulmonary AVMs and their mimickers.

  • This paper evaluates explanations for China's growth slowdown. The natural tendency for rapidly growing economies to slow down is a major factor, along with problems bequeathed by unbalanced growth, including a declining ICOR, slowing total factor productivity growth, and rising indebtedness. A number of other mechanisms are of lesser importance: demographics, President Xi's centralization of political power and anti-corruption campaign, and U.S. export controls. Sustaining growth in the longer term will require China to step away from investment, debt and export-fueled growth in favor of a balanced growth model with household consumption playing a larger role. Doing so will require hardening of the budget constraints of regional and local governments and restructuring of the nonperforming debts of property and construction companies.

  • This study is designed to examine characteristics and types of basic landscape design established by 7 local governments in Jeollanam-do and its availability as the index of landscape administration and present a guideline with view landscape plan of local governments. The results of this study are described below. In case of view landscape, while Korean cities have not many historical assets like landmark, they have locational characteristics with mountain or coast in the center or surroundings of downtown. Therefore, since view landscape has many cases of restricting individual property rights as well as having a value as public property of city which makes recognition of sharing city, it is very sensitive problem and establishing guideline of it is needed. But, it was found that view landscape plan of local governments established location of view spot with the nature of relief viewing downtown or coast from high spot. Selection of viewing objects in view plan require deciding an object as the public property of city and big cities require selection from the zone and small cities must select 1~2 spots from the viewpoint of whole downtown. 3~4 view spots of middle and distant views which makes city community centering around the subject of view must be selected through enough discussion and in case of natural landscape, View shaft or visible rays require setting of range that 30% of viewing objects is seen. View spot or viewing objects should be selected over twice as extra spots through public hearing and civil participation as the process.

  • Unlike continental European legal systems (civil law systems), specific performance in common law refers to an equitable remedy requiring exactly the performance that was specified in a contract. It usually granted only when money damages would be an inadequate remedy and the subject matter of the contract is unique. Thus, under common law specific performance was not a remedy, with the rights of a litigant being limited to the collection of damages. Consistent with the practice in civil law jurisdictions, United Nations Convention on Contracts for the International Sale of Goods (CISG) makes specific performance the normal remedy for breach of a contract for the sale of goods. Therefore, the buyer may require a breaching seller to deliver substitute goods or to make any reasonable repair. Likewise, the sellermay require the buyer to taker delivery of goods and pay for them. Despite this, Article 28 of the CISG restricts the availability of specific performance where it would be unavailable under the domestic law of the jurisdiction in which the court is located. Thus, the CISG's more liberal policy toward specific performance is restricted by common law. There are some legal issues in CISG's specific performance availability by Article 28. This paper analyzes these issues as interpreting Article 28 of CISG, by examining various theories of application to actions for specific performance and comparing CLOUT cases involving CISG Article 28.

  • This study aims to figure out the old people's needs for modification of their housing to maintain an independent lifestyle despite their health status and living arrangements. The total of 438 residents take part in the questionnaire survey research through the quota sampling method grouped by age (60-64 group, 65-69 group, 70-74 group, and over 75 group), sex (male and female), and house type (apartment houses and others). The results are as follows. (1) The old people's most inspired modification needs in interior spaces are remodeling the heating controls in the living room and the bedroom, ventilation facilities and storage spaces in the kitchen, non-slip tile flooring and ventilation facilities in bathroom, an easy door-lock, non-slip tile flooring, a draft cut-off, and storage spaces in the entrance. Besides they require emergency alarm, easy door and window locks, fire and gas alarm, and furniture with easy handling. It is necessary to supply the aged with the appropriate heating controls for their sensitivity to heat, with enough storage spaces for the increased possessions, and with diverse safety systems reflected blunting of mobility and sensibility. (2) As they grow older, the aged require more remote controls and safety facilities such as emergency alarm, easy locks and furniture with distinguishable colors. Male elderly is more concerned with safety, while female elderly do with convenience due to their different time spending in the house. The elderly residents in the apartment houses require the heating controls, a draft cut-off, and storage space less than other types of houses. Thus modification of the heating controls, a draft cut-off, and storage space are regards as basic needs for the elderly residents in non-apartment houses.

  • The purpose of this study is to analyze the inquiry activities of SCIIS and Korea primary school science curricular meterials and to make suggestions for the improvement of inquiry learning based on the analysis The Scientific Inquiry Evaluation Inventory (SIEI: Myung Hur, 1984) was used to evaluate the inquiry activity content of the primary school "Science, Level-6" and "SCIIS, Level-6" textbooks. The results are as follows: 1) The inquiry activities of Korean science textbooks are stressing on gathering and organizing data, but rarely require students to formulate a hypothesis, to design an experiment. 2) The SCIIS textbooks relatively tended to put more weight on interpreting/ analysing data and hypothesizing/ designing experiments. 3)The Korean science textbooks had little concern about establishing hypothesis and designing experiments, interpreting / analysing data. 4) The SCIIS textbooks require students to perform a variety of inquiry skills when compare to Korean science textbooks. 5) Competition / Cooperation Scale checks the level of competition and cooperation among student teams inherent in science curricular materials. The result from each team is incorporated into the formation of a class result. The communication is required to formulate a synthesized class response, enhances cooperation among teams. The SCIIS(84%) is the higher than Korea(50%) in cooperation scale. 6) Korean science textbooks rarely require students to discuss about experiment when compare to SCIIS textbooks. 7) Korean science textbooks provide students with both inquiry problems and experimental procedure, or including answers SCIIS textbooks provide students with both inquiry problems and experimental procedure, or problems only. 8) The Korean textbooks emphasize demonstrating or verifying of the text while the SCIlS emphasize extending the content of the text in inquiry scope scsle. The inquiry pyramid which helps analysis the inquiry activity curriculum as a whole is one of type 1- the course is centered on gathering and organizing data. The SCIIS are better than the Korean science textbook in the light of proportion of interpreting / analysing data and hypothesizing / designing experiments.
