The purpose of this study is to examine the factors affecting the baby boom generation's preparation for old age, and based on that, it will provide foundational data to improve the baby boom generation's preparation for life in old age. According to the study results, with regard to their socio-demographic characteristics, their sex, age, health conditions, average monthly income, attitudes to old age, and anxiety about aging may have significant effects on their preparation for old age. In other words, the degree of preparation for old age is higher in women than men, those who are older, those having better health conditions, those with higher average monthly income, and those with better attitudes to old age, and those whose anxiety about aging is lower. Based on the above study results, the paper intends to make the following political suggestions: first, it is needed to develop preparation for old age services appropriately for each generation's needs and characteristics in consideration of their socio-demographic characteristics. Second, it is necessary to provide education for preparation for life in old age by steps and change their consciousness to enhance their attitudes to old age. Third, it is needed to develop and distribute a variety of mental health programs that can lower their anxiety about aging.

Since infants' skin is very weak and has poor adaptability to environment, they are vulnerable to dermatitis caused by chemicals. Organic cotton for baby wear with the same functions in inner and outer wears can be considered the most suitable fiber. Therefore, this study analyzes products and colors of Korean and U.S. baby wear brands which use organic cotton. Of the total of seven organic brands of baby wear examined in this study, three were Korean baby wear brands and four were U.S. brands. and design colors of total 331 items were examined on the web. The results of comparative analysis showed that there were more U.S. brands than Korean brands in designs by uses. Color analysis showed that Korean natural cotton color was preferred and Y, G colors are commonly used, but colors of U.S. brands featured increased variety compared with Korean brands. Therefore, the Korean infant and toddler brand using organic cotton requires more diverse designs and delicate and broad colors.

We present a case of in-utero vesicoamniotic shunting and postnatal vesicostomy in a very low birth weight baby with posterior urethral valve syndrome. He was diagnosed as posterior urethral valve at $24^{+5$ weeks' gestation. Because of severe hydronephrosis and oligohydroamnios, the shunt was established by basket-shaped catheter at $27^{+0}$ weeks' gestation. After shunt, hydronephrosis improved. At $29^{+4}$ weeks' gestation, the shunt catheter escaped from its position and severe urinary ascites and hydronephrosis developed. At 30 weeks' gestation, the baby was born and showed elevated BUN and creatinine. On the 10th day of birth, vesicostomy was done for urinary drainage. Thereafter, the baby has been followed up for 10 months and has had recurrent episodes of urinary infection. We report the case with a brief review of literature.

Some taste compounds such as nucleotide and their related compounds, trimethylamine oxide (TMAO), trimethylamine (TMA) and total creatinine of sea mussel and baby clam during drying at 40, 50 and 60^{\circ}C$ and storage at low temperature$(4^{\circ}C)$ and room temperature$(20^{\circ}C)$ were investigated. Six kinds of nucleotide and their related compounds such as adenine triphosphate (ATP), adenine diphosphate (ADP), adenine monophosphate (AMP), inosine, adenosine and hypoxanthine were analyzed. The contents od adenosine in raw sample was high in sea mussel and baby clam. The contents of ATP, ADP and AMP decreased, while those of inosine and hypoxanthine increased during drying and storage periods. The contents of TMAO, TMA and total creatinine were low in sea mussel and baby clam. TMAO and total creatinine decreased but TMA increased during drying and storage periods. The rate of change was high in room temperature storage and for long storage periods than that of low temperature storage and for short storage periods.

The baby-step giant-step algorithm seeks b in a discrete logarithm problem when a,c,p of $a^b{\equiv}c$(mod p) are already given. It does so by dividing p by m block of $m={\lceil}{\sqrt{p}}{\rceil}$ length and letting one giant walk straight toward $a^0$ with constant m strides in search for b. In this paper, I basically reduce $m={\lceil}{\sqrt{p}}{\rceil}$ to p/l, $a^l$ > p and replace a giant with an adult who is designed to walk straight with constant l strides. I also extend the algorithm to allow $2^k$ adults to walk simultaneously. As a consequence, the proposed algorithm quarters the execution time of the basic adult-walk method when applied to $2^k$, (k=2) in the range of $1{\leq}b{\leq}p-1$. In conclusion, the proposed algorithm greatly shorten the step number of baby-step giant-step.

The intergenerational transfer between parents and children is a major concern due to low birth rates and aging society of Korea. This study investigated the influences of children's support for parent regarding parents' decision to bequest, including the influences of parental characteristics, household-related factors, and characteristics of children. The data are the 5th wave of KReIS, a sample of 1,834 married household heads(HHs), which were classified into 142 baby boomers (1955-1963), 534 post-liberation HHs (1945-1954), and 1,158 Japanese-era HHs (-1945). The results were as follows: First, 49.3% of baby boomer HHs, 59.2% of post-liberation HHs, and 59.1% of Japanese-era HHs, were willing to make bequest decision. Second, in the baby boomer HHs, although the children's contact with their parents represented an emotional resource transfer, a child's economic resource transfer to his/her parents did not affect the parents' bequest decisions. However, in the post- liberation HHs, children's contact with parents, and economic resource transfers were significant variables. In addition, in the Japanese-era HHs, only children's contact with their parents was a significant variable. Third, in the baby boomer HHs, the variables that influenced parents' bequest decisions were household financial assets and having a daughter rather than having son and daughter. However, the variables that heavily influenced bequest decisions of the post-liberation HHs were the presence of a spouse, home ownership, household expenditures, and satisfaction of relationships with children. In the Japanese-era HHs, the variables that significantly affected parents' bequest decisions were home ownership, household expenditures, and household financial assets.
