In the present experiment the amino acid composition in the pollen of Pinus taeda and Pinus rigida and methbolic changes of the composition occurring in germinating pollen were examined by the method of paper chromatography. The results obtained in this study are as follows. 1. The mature pollen of Pinus taeda and Pinus rigida contained 12.00%, 13.19% crude protein respectively and sixteen protein-constituting amino acids and three unknowns were detected on the chromatogram. 2. Main components of the protein-constituting amino acids were leucines, valine, alanine, glutamic acid and aspartic acid. 3. The free amino acids such as leucines, valine, tyrosine, alanine and glutamic acid increased evidently during germination of the pine pollen.

홍성옥(Sung Ok Hong),지 비 수이트(Geoffrey B . Sweet) 한국산림과학회 1977 한국산림과학회지 Vol.33 No.1

Seasonal changes in free arginine concentration in Pinus radiata buds were studied in four clones from May, 1974 to June, 1975. The buds were from the tips of first order branches which had flowered the previous year, and the significant findings were as follows: (1) In general, arginine concentration in the buds of the four clones showed the highest peaks from December to March, a period spanning the time of flower initiation, and the lowest levels in Angust and September. (2) The timing of individual arginine peaks during the period of flower initiation matched roughly the timing of initiation of several female cone clusters, as determined from Clone 7 which characteristically initiates three cycles of female cones on its leading shoot. (3) The heavy-flowering clones showed higher arginine concentration than ther poorer flowering ones, especially at the time of flower initiation.

A series of rooting experiments of P. radiata needle fascicles were carried out in test tubes using peat-pumice medium to see a possibility of rooting fascicles in test tubes and, if possible, to find out whether that method can improve the rooting. Typical rooting of clones from ortets aged 3, 7, 11. 18, and over 40, respectively, was 57%, 47%, 18%, 4%, and 2%. The effect of ortet ages upon rooting of fascicle cuttings was significantly exerted in these experiments. In the older ortets these results are not as good as those often obtained in a glasshouse. Hormones tested (indolebutyric acid and abscisic acid) had no significant effect on rooting and neither did a series of fungicides tested. Needle fascicles placed in an 18 hour day at 20˚/10℃ (day/night temperature) rooted signficantly better than those in a 10 hour day at the same temperature regime. The latter in turn rooted better than those set under a 10 hour day at 15˚/5℃. Clonal differences in rooting ability were also distinct in every trial of the present experiments with needle fascicles.

This study was conducted to analize the attitude toward work and occupation of middle school student in connection with the home environment in order to offer the helpful data on the career education. The data of the study were collected from 1,256 students of fourteen middle schools according to startified random sampling. The conclusions of this study were as follows. The middle school students responded to personality ethic which the students ought to have the chance of work according to their ability. The students thought work hard and painful in case of high value-oriented concept in home, but less hard and painful in case that they live in harmony and they are open-hearted, self-regulating. The students thought that to devote all their energies to the task in their hands was to obey God in case of high value-oriented concept, cooperative home atmosphere, tense tendency toword the guarantee of self-regulation, and many experience in their home. The students took a serious view of the personal interest and curiosity which they ought to have the chance of work according to their ability in case of high value-oriented concept, cooperative home atmosphere, open-hearted, self-regulating family. The students took a serious view of leisure and recess in case of high value-oriented concept, but didn`t take a seriouse view of leisure and recess in case of peaceful family, cooperative atmosphere in home. The attitude to occupation greatly responded to the self-realization conciousness which they intended to realize self-development by means of contribution to society or exhibition of creativeness. The students wanted to have the occupation of a good return for their efforts in case of high value-oriented conceit, but in case that they live in open-hearted and self-regulating family, they didn`t want do. The students took a serious view of the possibility of promotion and the fame in occupation in case of high value-oriented concept, cooperative home atmosphere. There was a tendency which the students took pleasure, got a feeling of achievement and satisfaction in performing their duty in case of cooperative home atmosphere and peaceful, open-hearted and self-regulating family. The tendency was found, which the students tried to realize self-development by means of contribution to society or exhibition of creativeness in case of high value-oriented concept cooperative home atmosphere, open-hearted and self-regulating family.

Majority of traumatic dental injuries occurs in younger people. Traumatic dental injury of maxillary anterior teeth can influence the pychologic and emotional states of patient. Proper diagnosis, rapid emergency treatment and periodic follow up are important for increasing a favorable outcome. The guidelines of IADT represent the current best evidence and practice based on literature research and professional’s opinion. The most important thing is to prevent trauma and to treat quickly following guidelines of IADT when injury occur for minimizing the complications.

스마트폰 기반 모바일뱅킹의 사용자 행동분석

스마트폰 이용자가 지속적으로 늘어나며 스마트폰 기반 모바일뱅킹 이용고객 또한 늘어나고 있다. 본 연구에서는 스마트폰 기반 모바일뱅킹 고객의 행동을 분석하고자 한다. 이를 위하여 이론적 연구모형을 제시하였으며, 실증분석을 위하여 10대에서 50대의 400명을 대상으로 설문조사를 실시하여 그 유의성을 검증하였다. 그 결과, 사회적 영향은 스마트폰 기반 모바일뱅킹의 편리성과 지각된 위험 그리고 지각된 보안에 영향을 미치고 있었으며, 편익의 요소 중 즉시성이 신뢰에 영향을 미치고 있었다. 또한, 지각된 위험이 높을수록 사용자의 저항이 더욱 크게 영향을 받았으며, 스마트폰 기반 모바일뱅킹의 사용의도는 신뢰와 저항 수준에 따라 영향을 받고 있었는데, 구체적으로는 저항을 낮출 때 보다 신뢰를 높일 때 더 높아지는 것으로 나타났다. Since smart phone users are continually increasing, smart phone based mobile banking users are increasing too. Therefore this study analyzes behavior of smart phone based mobile banking users. This study surveyed 400 people aged 10 to 50. The survey shows social effect influences convenience of smart-phone based mobile banking, perceived danger, and perceived security. Also, promptness , the element of convenience has influence on trust. As perceived danger was higher, it was more vulnerable to resistance. The intention of smart-phone based mobile banking was influenced by trust and resistance. Specifically rising of intention was more influenced by lifting trust than lowering resistance.

Purpose: In this study, A reliability assurance model (or reliability program) is proposed to evaluate the reliability of an armed vehicle. The reliability assurance is performed through the reliability-centered activities during its life cycle of development/design, production, deployment, maintenance, and disposal. Methods: By reflecting the current situations of korea defense industry, a reliability assurance model is built up based on the benchmarking results of world leading companies’ best practices in same fields. Results: The proposed reliability program of armed vehicles, which is based on the reliability program of ANSI/GEIA-STD 0009, uses DMAIC process of the six sigma methodology from design phase to testing and evaluation phase. Conclusion: This research is supposed to develop reliability program of armed vehicles by integrating DFSS, DFR and reliability growth process.

Purpose: Double sampling $T^2$ chart is a useful tool for detecting a relatively small shift in process mean when the process is controlled by multiple variables. This paper finds the optimal design of the double sampling $T^2$ chart in both economical and statistical sense under Weibull failure model. Methods: The expected cost function is mathematically derived using recursive equation approach. The optimal designs are found using a genetic algorithm for numerical examples and compared to those of single sampling $T^2$ chart. Sensitivity analysis is performed to see the parameter effects. Results: The proposed design outperforms the optimal design of the single sampling $T^2$ chart in terms of the expected cost per unit time and Type-I error rate for all the numerical examples considered. Conclusion: Double sampling $T^2$ chart can be designed to satisfy both economic and statistical requirements under Weibull failure model and the resulting design is better than the single sampling counterpart.
