Posner [Proc. Amer. Math. Soc. 8 (1957), 1093-1100] defined a derivation on prime rings and Herstein [Canad, Math. Bull. 21 (1978), 369-370] derived commutative property of prime ring with derivations. Recently, Bergen [Canad. Math. Bull. 26 (1983), 267-227], Bell and Daif [Acta. Math. Hunger. 66 (1995), 337-343] studied derivations in primes and semiprime rings. Also, in near-ring theory, Bell and Mason [Near-Rungs and Near-Fields (pp. 31-35), Proceedings of the conference held at the University of Tubingen, 1985. Noth-Holland, Amsterdam, 1987; Math. J. Okayama Univ. 34 (1992), 135-144] and Cho [Pusan Kyongnam Math. J. 12 (1996), no. 1, 63-69] researched derivations in prime and semiprime near-rings. In this paper, Posner, Bell and Mason＇s results are extended in prime near-rings with some conditions.

This study was undertaken to investigate college students' perception and preference of Korean traditional foods during November in 1994. 493 students in Taejon area were asked to fill out the questionaires. The collected data were analyzed by SAS package. The average height and weight were 173.04 cm, 64.46 kg for male and 161.73 cm, 49.33 kg for female. Students living their own home were 48.8% and self-lodging students were 30.2%. Male have a meal for hunger and female for pleasure (p<0.002). They choose their foods based on the taste (84.6%) and nutrition (8.2%). 85.5% of students prefer Korean traditional foods. Most students think that the Korean traditional foods should be succeeded and developed. However, they want the taste of Korean traditional foods to be changed for their preference. Kimch'i is the most favorate fermented foods. The fermented fish products and jang-atchi are the most unfavorate ones. They don't like too salty taste and strong smell of the Korean fermented foods.

The loss of Korean sovereignty by Japan in 1910 was an unforgettable national humiliation of Korea who maintained the sovereignty for 5000 years. The process of Korea annexation into Japan was reviewed and its consequences to the food and nutritional status of Koreans were analyzed by using the records in Korea as well as in overseas. The records of the colonial Government-General of Joseon shows superficial figures distorting the actual life of Koreans at that time. Japan extorted 45% of rice and 44% of soybeans produced in Korea in 1933, and imported poor quality long-grain rice (Indica type) to replace partly the extorted rice. The food and nutritional situation of Koreans was miserable, and hunger and malnutrition were prevalent in the country for the 36 years. The height of Koreans became smaller than Japanese, who was called as 'little people (Oein)' in Korea historically.

Squat reinforced concrete (SRC) shear walls are a critical part of the structure for both office/residential buildings and nuclear structures due to their significant role in withstanding seismic loads. Despite this, empirical formulae in current design standards and published studies demonstrate a considerable disparity in predicting SRC wall shear strength. The goal of this research is to develop and evaluate hybrid and ensemble artificial neural network (ANN) models. State-of-the-art population-based algorithms are used in this research for hybrid intelligence algorithms. Six models are developed, including Honey Badger Algorithm (HBA) with ANN (HBA-ANN), Hunger Games Search with ANN (HGS-ANN), fitness-distance balance coyote optimization algorithm (FDB-COA) with ANN (FDB-COA-ANN), Averaging Ensemble (AE) neural network, Snapshot Ensemble (SE) neural network, and Stacked Generalization (SG) ensemble neural network. A total of 434 test results of SRC walls is utilized to train and assess the models. The results reveal that the SG model not only minimizes prediction variance but also produces predictions (with R²= 0.99) that are superior to other models.

The production performance of multiparous lactating Sahiwal cows (n = 24) was evaluated according to both milking frequency and method. Selected animals were randomly divided into four groups containing six animals each under a completely randomized design. Cows in groups A & B were milked by the hand milking method three times per day, respectively. Similarly, cows in groups C & D were milked by the machine milking method two and three times per day, respectively. All animals were maintained under uniform feeding and management conditions. Dry matter intake was high in animal groups milked three times per day, and it remained unchanged between the hand and machine milking methods. Milk yield was higher (P < 0.05) in cows milked three times compared to those milked twice per day, and it did not differ between hand and machine milking methods. Milk fat percentage was higher (P < 0.05) in cows milked twice per day compared to those milked three times using both machine and hand milking methods. The percentage of total solids showed a similar pattern as the fat percentage. However, percentages of protein, lactose, and non-fat solids in milk were not significantly different (P > 0.05) among the treatment groups. Collectively, the results show that milking three times per day instead of twice at 8-hour intervals can enhance milk yield in Sahiwal cows using both hand and machine milking methods.

Objectives: The frequency of eating out among adolescents seems to be connected to a high rate of skipping breakfast and be interrelated to various nutritional problems. The purpose of this study was to assess the dietary habits of breakfast and eating out and investigate their relationships in male adolescents. Methods: This study conducted a cross-sectional survey. Dietary habits and eating out status were surveyed among 510 male students at a high school in Incheon and compared according to their breakfast skipping and breakfast type. Results: The percentages of subjects in the breakfast skipping group and breakfast group were 41.0% and 59.0%, respectively, and the breakfast group comprised a Korean meal group (74%) and a convenience meal group (26%). In the breakfast skipping group, the percentage of subjects buying and eating snacks due to hunger was 39.7%. Reasons for eating breakfast among subjects who ate breakfast were because parents prepared breakfast (41.9%) and out of habit (31.5%) in the Korean meal group, in contrast to because parents prepared breakfast (36.7%) and due to hunger (29.1%) in the convenience meal group (P < 0.001). Breakfast preparer was mother (91.4%) in the Korean meal group, in contrast to mother (67.1%) and self (20.3%) in the convenience meal group (P < 0.001). A high proportion of the breakfast group woke up at 07~07:30 or 06:30-07, whereas a high proportion of the breakfast skipping group woke up at 07~07:30 or after 07:30, showing a significant difference according to breakfast skipping (P < 0.001). A high proportion of the breakfast group spent 10,000 won (32.5%) a week eating out while a high proportion of the breakfast skipping group spent 20,000 won or more (28.2%), showing a significant difference (P < 0.01). Conclusions: About 40% of male high school students skipped breakfast and consumed snacks as a solution after breakfast skipping. The students who skipped breakfast spent more money on eating out. These results show that breakfast status may be related to eating out. Therefore, practical education on food choice and meal preparation along with regular breakfast instruction is needed in male adolescents.

Representation of destitution may be considered as an expression of a social desire toward forging a bond or solidarity with the impoverished. However, political and ethical demands of the solidarity force the formulaic framework structuring the form of representation to its limits. The thesis aims to examine the responses to such demands within the tradition of modernist literature that can be traced from Charles Baudelaire, Knut Hamsun to Franz Kafka and that somehow culminates with Samuel Beckett, and to analyze how the issue of destitution that weaves through Beckett's works criticizes and inherits such a heritage. Whereas destitution in 19th century Realism is structurally fixed and its potential for change is inherently excluded, for these writers, destitution is no longer the state of rigid reality in which any possibility is limited. It is destitution as an imperative that calls for exploitation of possibilities that can be recuperated from the impoverished condition of destitution. What these writers consistently resist against is destitution that leads to compensation and reward. Since occupying a superior position toward the other as the subject of description or sympathy can be seen as one form of profit or reward, they have persistently pursued absolute solitariness and austere conditions rather than prematurely simulating a sense of solidarity and community. The ultimate goal of destitution as an imperative is to pursue destitution in order to worsen it by identifying and then excluding and expending possessions and assets to a state of penury. This is a paradoxical process that opens up the realm of possibilities of destitution and redefines it as abundance and wealth. Destitution for Beckett as seen in the writers above is the objective of literature. But, what he focuses on is to amplify the shreds of economic world that still remain in a state of poverty and to reveal extreme poverty as a state of odd affluence and to transform it into a pursuit of accumulation and profit. One of his famous axioms, "less is more", contains the essence of such a paradoxical strategy. In a sense, such approach is a twist on the strategy that identifies and uses any remaining potential hidden in destitution as was pursued by other writers. It also expands on the imagination of the destitute described by Hamsun. But Hamsun and Beckett are diametrical opposites. Unlike Hamsun, Beckett does not link imagination with a sense of guilt. Imagination is not intended to overcome the destitute reality nor to culminate in artistic martyrdom as in the case of Kafka's hunger artist. The imagination of the impoverished in Beckett is simply a hilarious game and not an escape that ends in a sense of guilt. This game formulates a "rhetorical question" or derision at the ironical situation where the pursuit of hunger and art as the disinterestedness has been turned into symbolic capital. It is inherently a fundamental critique at the aestheticization of destitution that has been pursued by Modernism. Beckett's efforts at divulging falsehood inherent in non-profit acts such as charity, donation and hospitality are dissections of social fictions in which aestheticization of destitution remains a part of the whole.
