Although breast milk is the best food for infants, there will always remain a need for good substitutes when breastfeeding is not possible. Most of these substitutes are based on cow milk, but soy milk has been used as an alternative. It is necessary to ascertain that rearing infants on these formulas yields results comparable to those obtained by breastfeeding. Absorption of trace elements such as iron and zinc is well known to be higher from breast milk than from cow milk formula while absorption from soy formula is lower than from cow milk formula. The studies on the contents of iron and zinc in breast milk, cow milk formula and soy formula, and the intakes and blood levels of iron and zinc in infants fed breast milk, cow milk formula and soy formula, and the intakes and blood levels of iron and zinc in infants fed breast milk and cow milk formula were reviewd. The contents of iron and zinc in artificial formulas were higher than those in breast milk, and the intakes lf iron and zinc in infants fed cow milk, formula were higher than those in infants fed breast milk, However, the blood levels of iron in infants fed cow milk formula were significantly lower than those in infants fed breast milk, and there was no significant difference in the blood levels of zinc between infants fed cow milk formula and those fed breast milk. No results have been reported on the iron and zinc nutriture in Korean infants fed soy formula. More research should be focused on the potential consequences of excessive intakes of iron and zinc in infants fed soy formula as well as cow milk formula.

Association of 20 potential ATP2B1‐interacting genes with blood pressure in Koreans

Kyung‐Won Hong,Hyun‐Seok Jin,Ji‐Eun Lim,Bermseok Oh 한국유전학회 2011 Genes & Genomics Vol.33 No.3

Plasma membrane calcium‐transporting ATPase 1 (ATP2B1)is associated significantly with blood pressure in Caucasians and Asians. ATP2B1 regulates calcium homeostasis and belongs to the P‐type calcium pump family; several studies have identified diverse proteins that bind to ATP2B1. We hypothesized that ATP2B1 regulates blood pressure through ATP2B1‐interacting genes. To this end, 20 potential ATP2B1‐interacting genes were selected, 197 SNPs of which were analyzed for their association of systolic and diastolic blood pressure. These 20 genes were categorized into 2 groups: ATP2B1‐binding genes and ATP2B1‐cleaving calpain family members. Three ATP2B1‐binding genes (CALM1, NOS1, and PDLIM1)were associated with blood pressure, and a SNP in CALM1(rs2401887) generated the strongest association signal (beta=‐3.60±0.92, p=8.9×10^(‐5) for systolic blood pressure and beta=‐1.40±0.62, p=0.02 for diastolic blood pressure). Of the calpain family members, 3 genes (CAPN6, CAPN9, and CAPN10)were associated with blood pressure, and the CAPN10 SNP rs4676348 yielded the strongest association signal (beta=‐0.88±0.27, p=0.001 for systolic blood pressure and beta=‐0.58±0.18, p=0.015 for diastolic blood pressure). Further, the interaction of CALM1 to ATP2B1 was examined using the blood pressure of individuals who carried both variants of CALM1and ATP2B1 genes. Similarly the interaction of CAPN10 to ATP2B1 was also examined. The CALM1 variant (rs2401887)and CAPN10 variants (rs4676348) appear to decrease blood pressure further in addition to the decrease by the variant (rs17249754) of ATP2B1, which suggests that ATP2B1 might regulate blood pressure through the ATP2B1‐interacting genes CALM1 and CAPN10.

A. The necessity and purpose of the study Since 1960s the number of university and college students has increased due to the rapid industrial development which requires more technical and intellectual persons. Also the upward spreading effects of education with generalization of secondary education have increased the social demands of liberal education, which expedite university students' diversity and heterogeneity. Therefore, the problems of students are no longer those of school authorities, but expand into social and national problems. Recently most of university in Korea have put more emphasis on the rearrangement and reinforcement of Student Guidance System. Especially, in case of Jeju National University, taking into considerations the special geographical conditions far away from the Korean mainland, and transitional stage on which JNU was promoted to national full-university status, along with the unification of campuses, the more careful interests and efforts are required for student guidance. This study was conducted with a view to providing the opportunities of educational and social specialization of student guidance. The following are the purpose of this study: 1) To set up directions for student guidance which can carry out the role and function of the university. 2) To consider, in the aspect of education, the main factors which influence the problems of university students. 3) To find out the difference between the problems of students' demand and abilty and realities of guidance, by comparing and analyzing present guidance realities between universities. 4) To offer improvement directions for efficient student guidances. B. The scope and contents of the study 1) The problem of student guidance in view of the purpose and function of a university. 2) The fundamental viewpoint of guidance in university 3) A theoretical investigation for efficient student guidance 4) A root cause of student problems 5) The present condition and problems of student guidance 6) Improvement directions for guidance C. The method of the study 1) To analyze the domestic data as well as foreign data 2) To analyze the questionnaire 3) To analyze the results of guidance through the actual result reports of student guidance 4) To analyze various data of student guidance 5) To represent by percentage(%) the realities and problems of student guidance D. The problematic factors of student guidance in the light of purpose and function of a university 1) The original purpose and functions of university are the acquisition of knowledge the transmission of knowledge, and application of knowledge. They are based on the wholemen community of intellectuals in which research, education, and service are determined to be prime mission, but hasn't well been fulfilled because of the present special situations of Korea. 2) In the expectations of university's roles, it is becoming important to harmonize the real desire of administrative officials, intellectual desire of professors, and idealistic of students with each other. 3) A university's research function of creating academic atmosphere is very unsatisfactory. 4) The relationship between professors and students, and even among students hasn't well progressed because of excessive solicitude of omission by graduation quota system as well as full classes. And cultural education is not conducting effectively because it is very fragmentary and formal. 5) The chaos is being produced about the establishment of concept of community service given to university education, the ways and limitations of participation in society and actual world. E. The viewpoint of student guidance The contents and methods of student guidance are decided according to the view of students to be the subject of guidance. In the reformative viewpoint of student guidance by educative instruction methods, main method of guidance are authority, blind obediance, cramming, subjectivity, control, rectification. From the educative viewpoint of student guidance, self-direction can be possible by means of students' interest, desire and ability. Future student guidance must be conducted to develop their potentiality and natural ability of growth without external force or blind gramming. F. Following theoretical investigation were enforced in order to establish effective directions for student guidance. 1) The concept and purpose of the orientation for freshmen and its basic policy and contents 2) The necessity and contents of department arrangement guidance 3) The practice of alloted academic adviser system 4) The educational functions, necessity, and meaning of campus extracurricular activity 5) The role and function of student government(SNDC) 6) The welfare and scholarship system for students G. As a result of a selection of root causes of student problems from the introspection, the following were important order of immediate and expected problems 1405 freshmen; 1. Studies Problem(40.3%) 2. Course problem(36.4%) 3. Economic life problem(36.9%) 4. Social fitness Problem(26.7%) 5. Health Problem(16.0%) The investigation consequence for sophomore and junior are following; 1. A course Problem(35.2%) 2. Economic life problem(35.4%) 3. Human relation problem between professor and student(35.2%), and a good use problem of spare time(35.2%) 4. Studies problem(26.4%) H. The problems were revealed by a statistics which were investigated and analyzed realities of student guidance as follows, respectively: 1. In the orientation for fresh, it is emphatic to give only a information, the program of a important purpose in an orientation that are helpful to initiation of university life with a safety emotionally by withdrawing from strain from strange environment is making light of. 2. In the guidance of a department choice, department allocation by a record is making without giving a chance searching for self-characteristic like aptitude or hobbies, the guidance plan and materials of objectivity are not prepared, and the chance choosing carefully comes very short of. 3. In the management of partial charge professors system, the relation position between professor and student is very formal because, as a matter of fact, it is meaningfulness to guide students from a professor is responsible for guidance of so many students, director of professors are in want of the whole recognition about guidance contents. 4. Though the circle activities are very important as an educational function, a director professors of a circle has charge of guidance for so many students, the activities without purpose consciousness are unfolding, the activities with interest and recreation mainly are rich in, and the activities for enlightenment sound activity model which gets a value experience are situation insufficiency itself. 5. In the activities and management of Student Body, he is not accomplishing plan and function by nature, the activities and management individual and new are very lack owing to emphasis of events centre and actual results centre. And the appearance of making heteronomy now that he is not also chose relation to the circles in SNDC is more and more deepening. 6. The lower organization taking charge of students guidance specially in managent of the students guidance institute are in need, the number of specialists are for want of, it is just so formal to run the students guidance institute because the institute's finance is in very poverty, its originally functions are not accomplishing due to the consultation mood in consultation room is stiff. 7. Our university lacks in research facilities and mental incentive with regard to student welfare function. I. I am directing the way of student guidance for withdrawing from and getting rid of the problems revealing, concerning the students guidance to the best of his ability by the realities of students problems as follows; First, the investigation and research activities and assistance understanding and helping students have to provide in the side of prevention of problems by understanding university students' nature consciousness and characteristic regularly. Second, students' spontaneous participation, the development of interesting and useful programmes, and faculty members' active supports & guidance should be given to obtain effective result of fresh's orientation. Third, school authorities should provide freshmen with opportunity to judge their aptitudes from the time of entrance by holding orientation several times, and by offering detailed informations on the department selection. Fourth, The academic & human relations between professors and students should be maintained through proper enforcement of alloted academic professor system. Fifth, every circle and club should established proper and patent objectivities of activity, and try, to create and introduce useful and interesting programmes in order to promote an educational function of each circle and club. Sixth, in order to eleminate the gap between students and Students Government, students should take deep interests in Student Body's activity, while Student Body should develop academic and literary activity to promote students research activities. Seventh, in order to promote the function of Student Guidance Institute, there should be secured expert staff for smooth counselling, investigation and employment guide as well as financial and administrative support of school authorities. Finally, university authorities should organize several institute such as student welfare committee(institute) so that they might grasp what student opinions & desire are and make students lead comfortable campus lives.

Zirconia is a heat-resistant material with a high melting temperature(2700℃) and has low thermal conductivity and excellent corrosion resistance. However, application has been limited due to brittleness, which is a disadvantage of ceramic materials. As a way to improve this, the addition of Y3+ improves the strength by phase transformation, which can improve the brittle problem, which is a disadvantage of ceramic. Many studies have been conducted on the addition of Y3+ after the addition has been found to be more efficient than the other additives. In this experiment, have studied the additives that replace this Y3+. Expeiments on the possibility of replacing Y3+ by adding an alternative additive considering Zr-sol(Fe2+, Fe3+, Er3+) in consideration of Atomic size, Crystal ionic raddi and Effective Ionic raddi. ZOC(ZrOCl2*8H2O) was dissolved in distilled water and synthesized by hydrothermal synthesis at 160℃ for 24hours. The formed Zr-sol was separated into a supernatant and precipitate. The supernatant was washed with distilled water, and the presence of chloride ion was confirmed using AgNO3. And add to the cleaned Zr-sol an additive that is believed to be a substitute for Y3+. The prepared Zirconia was calcined at 900℃ for 2hours, and the crystal phase was analyzed by XRD similar that of YSZ. The calcined powder was uniaxial pressed and sintered at 1500℃ for 2hours. The sintered specimens were first measured for specific gravity. And the particle size distribution, EDAX and FESEM were measured. 지르코니아는 고온에선 용융하는 (2700℃) 낮은 열전도율과 부식저항이 우수한 세라믹이다. 이에 우수한 파괴인성을 주기 위해 3 mol % Y를 첨가하게 되고, 상온에서 정방정 상으로 존재함으로써 파괴인성이 증가한 것으로 알려져 있다. 따라서 본 실험에서는 Y와 유효 원자 반경이 유사한 Er3+ (89pm)를 첨가함으로써, 과연 어떤 변화가 나타나는지를 알아보았다. 또한 원자가가 유사한 Fe3+와 Fe2+ 를 첨가하여 물성변화와 상변화를 조사하였다. 연구결과 이온 반경이 Y와 유사한 Er3+에서는 완전한 정방정상과 밀도, 투광율 (일부 파장은 제외)을 나타내었으나, 이온 반경이 약1/2 인 Fe2+, Fe3+를 첨가한 경우에는 단사정과 비정질 그리고, 650nm이하의 파장에서는 거의 투광하지 않는 현상을 보였다.

ABSTRACT This study was conducted to determine influence of planting date, seeding rate and phosphate rate on main growth, characters, yield and chemical composition of senna from March 11, 1998 to December in Cheju Province. Days to flowering was lessened as planting date was delayed. The plant height of senna was the longest at 31 March planting (99cm) than at the other planting date. Stem diameter, number of leaves were increased at 31 March but number of branches was not affected by planting date. And number of withering leaves were increased as planting date was earlier. Fresh forage yield per lOa, for senna was the greatest (4,660kg) at 31 March planting, the second was 4,397kg at 1 April planting and the reduced the 3,473kg at 11 March planting. Also dry matter yield per lOa, crude protein yield and total digestable nutrient (TDN) yield was nearly the same tendency. Crude protein, crude fat percent was the greastest at 11 March planting and than decreased with further increased at planting date. Crude ash and crude fiber percent was decreased tendency as planting date was delayed. Nitrogen free extract (NFE), TDN percent was increased tendency as planting date was delayed. SPAD reading value of leaves had an efficiency increased as planting date was delayed.
