On the purpose to suggest an advanced scheme in assessing the domestic wheat quality, this paper reviewed the inspection systems of wheat in major wheat producing countries as well as the quality criteria which are being used in wheat grading and classification. Most wheat producing countries are adopting both classifications of class and grade to provide an objective evaluation and an official certification to their wheat. There are two main purposes in the wheat classification. The first objectives of classification is to match the wheat with market requirements to maximize market opportunities and returns to growers. The second is to ensure that payments to glowers aye made on the basis of the quality and condition of the grain delivered. Wheat classes has been assigned based on the combination of cultivation area, seed-coat color, kernel and varietal characteristics that are distinctive. Most reputable wheat marketers also employ a similar approach, whereby varieties of a particular type are grouped together, designed by seed coat colour, grain hardness, physical dough properties, and sometimes more precise specification such as starch quality, all of which are genetically inherited characteristics. This classification in simplistic terms is the categorization of a wheat variety into a commercial type or style of wheat that is recognizable for its end use capabilities. All varieties registered in a class are required to have a similar end-use performance that the shipment be consistent in processing quality, cargo to cargo and year to year, Grain inspectors have historically determined wheat classes according to visual kernel characteristics associated with traditional wheat varieties. As well, any new wheat variety must not conflict with the visual distinguishability rule that is used to separate wheats of different classes. Some varieties may possess characteristics of two or more classes. Therefore, knowledge of distinct varietal characteristics is necessary in making class determinations. The grading system sets maximum tolerance levels for a range of characteristics that ensure functionality and freedom from deleterious factors. Tests for the grading of wheat include such factors as plumpness, soundness, cleanliness, purity of type and general condition. Plumpness is measured by test weight. Soundness is indicated by the absence or presence of musty, sour or commercially objectionable foreign odors and by the percentage of damaged kernels that ave present in the wheat. Cleanliness is measured by determining the presence of foreign material after dockage has been removed. Purity of class is measured by classification of wheats in the test sample and by limitation for admixtures of different classes of wheat. Moisture does not influence the numerical grade. However, it is determined on all shipments and reported on the official certificate. U.S. wheat is divided into eight classes based on color, kernel Hardness and varietal characteristics. The classes are Durum, Hard Red Spring, Hard Red Winter, Soft Red Winter, Hard White, soft White, Unclassed and Mixed. Among them, Hard Red Spring wheat, Durum wheat, and Soft White wheat are further divided into three subclasses, respectively. Each class or subclass is divided into five U.S. numerical grades and U.S. Sample grade. Special grades are provided to emphasize special qualities or conditions affecting the value of wheat and are added to and made a part of the grade designation. Canadian wheat is also divided into fourteen classes based on cultivation area, color, kernel hardness and varietal characteristics. The classes have 2-5 numerical grades, a feed grade and sample grades depending on class and grading tolerance. The Canadian grading system is based mainly on visual evaluation, and it works based on the kernel visual distinguishability concept. The Australian wheat is classified based on geographical and quality differentiation. The wheat grown in Australia is predominantly white grained. There are commonly up to 20 different segregations of wheat in a given season. Each variety grown is assigned a category and a growing areas. The state governments in Australia, in cooperation with the Australian Wheat Board(AWB), issue receival standards and dockage schedules annually that list grade specifications and tolerances for Australian wheat. AWB is managing "Golden Rewards" which is designed to provide pricing accuracy and market signals for Australia's grain growers. Continuous payment scales for protein content from 6 to 16% and screenings levels from 0 to 10% based on varietal classification are presented by the Golden Rewards, and the active payment scales and prices can change with market movements.movements.

Для основных ведущих стран Азиатско-Тихоокеанского региона США, Китая и России сложилась ситуация "новой нормальности". Причем для каждой из указанных стран эта "новая нормальность" имеет свои собственные особенности, характеристики и значение. Для США – это обострение военного противостояния с Китаем в Тайваньском проливе. Для Китая – обострение соперничества с Соединенными Штатами до нового уровня и, одновременно, замедление темпов экономического развития с очень высокой вероятностью их дальнейшего снижения. "Новая нормальность" для России – это почти полное свертывание отношений с США, ЕС и их партнёрами и союзниками на фоне специальной военной операции и введенных санкций. Эти нюансы, в дополнение к результатам 20-го съезда КПК, во многом и будут определять основные тенденции в китайско-американских и китайско-российских отношениях. С высокой вероятностью отношения Китая и России не претерпят серьезных изменений на фоне украинского кризиса. Пекин будет стараться сохранять позицию "доброжелательного нейтралитета" по отношению к Москве. В то же время баланс между "доброй волей" и "нейтралитетом" может варьироваться в зависимости от масштабов китайско-российского сотрудничества. Например, в экономической сфере китайские компании будут лимитировать сотрудничество с российскими партнерами, опасаясь западных вторичных санкций. Однако, в целом, Россия сохранит свое значение для Китая как сильнейший антиамериканский полюс. В отношениях с США Китай продолжит твердо отстаивать свои интересы, в то же время, не исключая нормализации отношений с Вашингтоном в определенных областях сотрудничества: стратегическая стабильность, нетрадиционные угрозы, экология и т.д. В целом решения 20-го съезда КПК не позволяют говорить ни за, ни против идеи о готовности Китая возобновить диалог с США в период после конгресса. Китайско-американские отношения, как отмечалось выше, имеют свою собственную логику и, вероятно, продолжат развиваться в ее рамках. Впрочем, как и китайско-российские отношения. В рамках этой логики Пекин, похоже, продолжает балансировать между двумя векторами своей внешней политики. С одной стороны – это развитие двустороннего сотрудничества с Россией с целью укрепления собственных переговорных позиций в противостоянии с Вашингтоном: военное сотрудничество с акцентом на совместные учения, политическое сотрудничество, основанное на антиамериканизме, экономическое сотрудничество с оглядкой на риски вторичных санкций. С другой стороны, для Китая неприемлемо, во-первых, нарушение территориальной целостности Украины, во-вторых, прямое военное столкновение с США и, в-третьих, дальнейшее обострение отношений с Вашингтоном по фактору китайской дружбы с Россией.

Purpose: The present study was performed to evaluate the effect of surface treatment of the cervical area of implant on bone regeneration in fresh extraction socket following implant installation. Materials and methods: The four minipigs, 18 months old and 30 kg weighted, were used. Four premolars of the left side of both the mandible and maxilla were extracted. ${\phi}$3.3 mm and 11.5 mm long US II plus implants (Osstem Implant co., Korea) with resorbable blasting media (RBM) treated surface and US II implants (Osstem Implant co., Korea) with machined surface at the top and RBM surface at lower portion were installed in the socket. Stability of the implant was measured with $Osstell^{TM}$ (Model 6 Resonance Frequency Analyser: Integration Diagnostics Ltd., Sweden). After 2 months of healing, the procedures and measurement of implant stability were repeated in the right side by same method of left side. At four months after first experiment, the animals were sacrificed after measurement of stability of all implants, and biopsies were obtained. Results: Well healed soft tissue and no mobility of the implants were observed in both groups. Histologically satisfactory osseointegration of implants was observed with RBM surface, and no foreign body reaction as well as inflammatory infiltration around implant were found. Furthermore, substantial bone formation and high degree of osseointegration were exhibited at the marginal defects around the cervical area of US II plus implants. However, healing of US II implants was characterized by the incomplete bone substitution and the presence of the connective tissue zone between the implant and newly formed bone. The distance between the implant platform (P) and the most coronal level of bone-to-implant contact (B) after 2 months of healing was $2.66{\pm}0.11$ mm at US II implants group and $1.80{\pm}0.13$mm at US II plus implant group. The P-B distance after 4 months of healing was $2.29{\pm}0.13$mm at US II implants group and $1.25{\pm}0.10$mm at US II plus implants group. The difference between both groups regarding the length of P-B distance was statistically significant(p<0.05). Concerning the resonance frequency analysis (RFA) value, the stability of US II plus implants group showed relatively higher RFA value than US II implants group. Conclusion: The current results suggest that implants with rough surface at the cervical area have an advantage in process of bone regeneration on defect around implant placed in a fresh extraction socket.

Aiming at nature's early restoring needs to select plant species harmonizing with surrounding environment that fits to restoring goal of ultimately aiming at woody plants dominant vegetation that protect and stabilize surface parts of bared slopes. And it is important to make it assimilated with surrounding natural vegetation by differentiating planning of seed mixtures. Natural Ecological Restoring Construction Methods (JSB Method) was developed to increase the effect of landscape change according to seasons not to simple hydro-seeding by reducing rate of foreign grasses while raising rate of wild flower using. It was considered that using wild flowers that bloom on each season solved the problems of slope landscapes that looks artificial and uninteresting. After researching environmental condition of the slopes, JSB Method has shown that, as of wet-type method, soil is relatively soft and the difference of thickness of plant base soil media affects on the difference of soil hardness. In case of soil hardness of 8.8~17mm, there's dangerousness of slope's collapsing, but it has shown that growth of plant was favorable. For the acidity of soil, most of them are in the type of neutralized soil of more than pH 6. And after analyzing the degree of woody plants dominance, it had shown that lower part was occupied with wild flowers and other herbaceous species like China pin, golden phesant mum, pitcher plant, and middle and upper part was occupied with woody plants like silk-tree, sumac forming multi-layer structure. It can be concluded that the restoration objects of the woody plant vegetation on the roadside slopes can be accomplished successfully by Natural Ecological Restoring Construction Method (JSB method).

현재 국내에서는 연약지반의 성토를 실시할 경우 성토사면의 안정을 관리하는데 있어 외국의 기준에 의존하는 경향이 있다. 현장에서 일반적으로 사용되고 있는 방법으로 곡선안정관리법, 변위속도안정관리기법, 직선안정관리기법, 성토하중관리법 등이 사용되고 있다. 본 연구는 수치해석을 통해 사면안정과 성토 안전관리법의 적용성을 검토하였다. 연구결과 곡선안정관리법은 다소 과대한 것으로 평가되었으며 직선안정관리법은 갑작스런 파괴의 위험이 있는 것으로 계측관리에 세심한 주의가 필요할 것으로 평가되었다. 그러나 변위속도 안정관리법은 과소평가되는 경향이 있으나 이는 현장의 불확실성을 고려할 때 현장적용에 적합한 것으로 평가되었다. 성토하중관리법은 파괴기준 값이 ${\Delta}_q/{\Delta}{\delta}$의 값보다 클 경우 안정하다고 평가하는 방법으로 실무에 적용할 경우에는 파괴기준 값의 산정에 어려움이 있다. 따라서 본 연구에서는 성토하중에 대한 ${\Delta}_q/{\Delta}{\delta}$값이 계속적인 증가 경향을 보일 경우 안정한 것으로 평가되었다.
