This study is intended to comparison of the recent ideal number of children and atrial approach for analyzing value system for children that form attitude affecting birth control with earlier study conducted 10 years ago. In general the traditional fertility pattern of Korea may be considered as 'early marriage and high fertility' backed by the confucian value system of a farming-oriented country. A selective attitude favoring sons contributes substantially to fertility. But Korea is now moving toward a late marriage and fertility pattern. This has been due to the repid introduction of western culture and a partial acceptance of western value systems, a relative weakening of traditional value systems, a gradual increase in infant and child servival rates thresh medicines, and a desire to avoid having too many children because of economic poverty. This study showed following results: Ideal number of sons and daughters in urban area was decreased by 0.2 respectively compared to earlier study. In rural area, the number of decrease of sons and daughters was 0.5 and 0.2 respectively. The conception concerning Happiness has changed to wealth from health in previous opinion. Regarding attitude toward having sons, 98 percent of them wanted to have sons positively, moreover 10 percent of them wanted two or more sons. Regarding reasons for the wanting sons, we see that economic and traditional considerations, such as dependance in old age, and inheritance of the family line, are a principle concern of about 56 percent in both areas. The rate of dependence in old age was decreased conspicuously compare to previous study while the rate of helding rituals was increased remarkably in rural area. Among reasons for limiting family size. 'for better living and for better education for their children were main rasons reted 46 percent in urban, 51 percent in rural areas. The rates were not changed compare to previous study. Regarding attitude of those who have no son or children, the rate of re-marriage with second wife was decreased remarkably in rural area and the rate of living without special behaivor for having son was increased compare to previous study.

The structure, clonal grwoth, shoot modules dynamics and rhizome respiratory rate of the Phragmites longivalvis circular patch were studied in a 15-year-old reclaimed land on Mado of the western Korea for two growing seasons. Clonal growth by P. longivalvis resulted in subpopulations of shoot modules which may be separated into pioneer, mature and senile growth phase. The radial growth of circular patch was 208 cm per a year. The shoot phytomass, shoot height and spike frequency were the lowest in the senile phase, and were the highest in the mature phase. The maximum shoot phytomass of pioneer, mature and senile phase in August was 347, 536 and 195g/$\m^2$ for the first year, and 609, 748 and 248g/$\m^2$ for the second year, respectively. The birth rates of shoot modules were the highest during the early spring. Of all modules, the percemtage of spring cohort of pioneer, mature and senile growth phase were 52, 82 and 70% for the first year, and 83, 88 and 85% for the second year, respectively. The flowering shoots were only derived from spring cohorts. The death rates of shoot modules of the pioneer and mature phase were the highest in October. The module is an annual semelparous plant though the genet is a perennial iteroparous plant. Their survivorship curve was negatively (Deevey type I). The density of shoot modules of the pioneer, mature and senile growth phase increased as much as 4.0, 1.6 and 2.3 times for one year, respectively. The respiratory rate was the highest in the lowest in the senile growth phase.

The growth rates of manufacturer M, the domestic market leader in the infant formula and dairy industry, has slowed because of the market reduction which is caused by the falling birth rates, the increasing growth in import of foreign~made infant formula and fierce competition with other rivals in domestic market. In this situation, they find a way to make new opportunities of service innovation by using 'Open Collaboration Innovation Methodology(OCIM)'. As s result, they can provide their customers with the differentiated service which is created by collaborating with the external partners, exchanging the value each other and connecting the accumulated internal capabilities to the external resources. This study focused on the application of the Open Collaboration Innovation Methodology which is used to the manufacturer M's servicitization. Also it is described in the direction of forth study based on the limits that occurred when the M company use the methodology and the matters that have to be considered when other companies apply the methodology.

The purpose of this study was to investigate pregnancy, abortion and delivery rates among Korean teenagers. The subjects of this study were 11,433 teenagers aged 13-19 years in Seoul, Pusan, Taegu, Kwangju, Incheon, Taejeon and Ansan, Korea. Data were collected from Feb. 1994 to May 1995, 16 months, by schoolnurses or the researchers. The results showed pregnancy rate was 7.2 per 1,000 teenagers, the abortion rate was 4.3 per 1,000 teenagers, and the delivery rate was 1.2 per 1,000 teenagers. In the pregnancy experience, the main factors related to teenage pregnancy were love or marriage engagement. In the abortion experience, 53.9% of teenagers had had more than two abortion experiences, 38.1% midtrimester abortion, 22% complications after abortion, 36.0% sexual activity after abortion and 86.7% the financial support from partners or friends for abortion. In the delivery experience, 64.3% of teenagers delivered with no prenatal care and 42.9% had a delay in realizing they were pregnant. Fifty percent were delivered by non-professionals in non-medical institutions.

Background: Breast cancer is the most common malignancy in women worldwide and its incidence is generally increasing. In 2012, it was the second most common cancer in the world. It is necessary to obtain information on incidence and mortality for health planning. This study aimed to investigate the relationship between the human development index (HDI), and the incidence and mortality rates of breast cancer in the world in 2012. Materials and Methods: This ecologic study concerns incidence rate and standardized mortality rates of the cancer from GLOBOCAN in 2012, and HDI and its components extracted from the global bank site. Data were analyzed using correlation tests and regression with SPSS software (version 15). Results: Among the six regions of WHO, the highest breast cancer incidence rate (67.6) was observed in the PAHO, and the lowest incidence rate was 27.8 for SEARO. There was a direct, strong, and meaningful correlation between the standardized incidence rate and HDI (r=0.725, $p{\leq}0.001$). Pearson correlation test showed that there was a significant correlation between age-specific incidence rate (ASIR) and components of the HDI (life expectancy at birth, mean years of schooling, and GNP). On the other, a non-significant relationship was observed between ASIR and HDI overall (r=0.091, p=0.241). In total, a significant relationship was not found between age-specific mortality rate (ASMR) and components of HDI. Conclusions: Significant positive correlations exist between ASIR and components of the HDI. Socioeconomic status is directly related to the stage of the cancer and patient's survival. With increasing the incidence rate of the cancer, mortality rate from the cancer does not necessariloy increase. This may be due to more early detection and treatment in developed that developing countries. It is necessary to increase awareness of risk factors and early detection in the latter.

Background: The aim of this study was to evaluate the incidence and mortality of stomach cancer, and its relationship with the Human Development Index (HDI) and its components in Asia in 2012. Materials and Methods: This ecological study wa conducted based on GLOBOCAN project of WHO for Asian countries. We assessed the correlations between standardized incidence rates (SIR) and standardized mortality rates (SMR) of stomach Cancer with HDI and its components using SPSS18. Results: A total of 696,231 cases (68.7% in males and 31.3% in females, ratio of 2.19:1) and 524,465 deaths (67.1% in men and 33.0% in women, ratio 2.03:1) were included in 2012. Five countries with the highest SIR of stomach cancer were Republic Korea, Mongolia, Japan, China and Tajikistan. Five countries with the highest SMR of stomach cancer were Mongolia, Tajikistan, Kyrgyzstan, Kazakhstan and China. Correlation between HDI and SIR was 0.241 (p = 0.106), in men 0.236 (p = 0.114) and in women -0.250 (p = 0.094). Also between HDI and SMR -0.250 (p = 0.871) in men -0.018 (p = 0.903) and in women -0.014 (p = 0.927). Conclusions: No significant correlation was observed between the SIR of stomach cancer, and the HDI and its dimensions, such as life expectancy at birth, mean years of schooling, and income level of the population.

Purpose: This study was done to investigate the effects of breast-feeding education and support services on rate of breast-feeding three and six months after birth, and the effect on infant's growth (weight, height, body mass index [BMI]). The experimental group which had both education and support services was compared with the control group which had only breast-feeding education. Methods: This study was a quasi-experimental study with a time-series design. The participants were 39 mothers who were hospitalized for childbirth. Twenty mother were assigned to the experimental group and 19 mothers, to the control group. The breast feeding education was done during hospitalization, and support services were provided once a week after discharge for a month (a total 4 times) by a maternity ward nurse. Data regarding breast-feeding rate at one month after childbirth was collected by phone call; the breast-feeding rates at three and six months after childbirth were collected in a visit to the families. The child's weight and height were also measured during the visit. Results: The experimental group had a statistically significant higher rate for frequency of breast-feeding at one, three and six months after childbirth than the control group. However, there was no meaningful difference between the two groups for infant growth. Conclusion: The results of this study suggest that breast-feeding education is helpful for a start, but support services are also necessary to sustain breast-feeding.

Objective: Embryo loading (EL) is a major step in embryo transfer (ET) and affect on the success of in vitro fertilization (IVF). This study aimed to compare the effect of two different EL techniques on the rates of pregnancy and delivery in IVF/ET cycles. Methods: 207 fresh ET and 194 Frozen-thawed ET (FET) cycles were included in this retrospective study. Two groups (A and B) were defined based on the EL technique used. In group A, the entire catheter was flushed with Ham's F-10 medium. The embryos were then drawn into the catheter using one air bracket. In group B, $70{\mu}L$ of air was aspirated into the syringe and the catheter was flushed using Ham's F10 medium. The medium, air, embryos, air, and finally another layer of medium were then sequentially drawn into the catheter. The main outcome measures were the pregnancy and delivery rates. Results: The groups did not differ with respect to the etiology of infertility, the source of spermatozoa, the quality of the embryos, the type of EL catheter, and the ease of transfer. The pregnancy rate was similar between two groups. In fresh ET cycles, a higher delivery rate was observed in group B than it group A (78.1% vs. 60%, p=0.1). In FET cycles, the rate of delivery was significantly higher in group B than in group A to a nonsignificant extent (88.9% vs. 58.8%, p=0.06). Conclusion: EL techniques did not have a significant impact on the delivery rate in either fresh or FET cycles.

Completeness is an important indicator of data quality in cancer registry programs. This study aimed to estimate the completeness of registered cases in a population based cancer registry program implemented in five provinces of Iran. Capture-recapture methods were used to estimate the number of cases that may have been missed and to estimate rates of completeness for different categories of age, year, and sex. The data used for this study were obtained from three sources: 1) National Pathology Database; 2) National Hospital Discharge Database; and 3) National Death Registry Database. The three sources were linked and duplicates were identified based on first name, last name, father's names, and date of birth, ICD code, and case's residency address using Microsoft Excel. Removing duplicates, the three sources reported a total of 35,643 cases from March 2008 to March 2011. Running many different multivariate models of capture-recapture and controlling for source dependencies revealed an overall under-reporting of 49% in all five registries combined. The estimated completeness differed based on age, sex, and year. The overall completeness was higher for males than females (71.2% for males and 59.9% for females). Younger age had lower rates of completeness compared to older age (38.1% for <40 years, 55.4% for 40-60 years, and 76.7 for >60 years). The results of this study indicated a moderate to severe (depending on the age, sex and year) degree of completeness in the population based cancer registration of Iran.

During the period of 1962 through 1981, a total of 11. 7 million cummulative acceptors have received contraceptive services under the national family planning program. The number of annual acceptors have steadly increased from 151, 200 in 1963 to 842, 200 in 1975, and since then it has maintained the range of 600, 000 to 800, 000 acceptors per year. From the beginning of the program, the IUD had been the principal method of contraception provided by the government program until 1976, at which time the government made female sterilization services available thorough the introduction of the laparoscopy method. The popularity of female sterilization has increased very rapidly during the last few years. Out of 614, 200 program acceptors in 1981, the proportion of female sterilization and IUD acceptors were virtually the same(26.8% and 27.2% respectively). Considering various anticipated problems such as a large proportion of contraceptive users for the fertility termination and the high discontinuation rates of IUD and other traditional method, the government has emphasized the distribution of female sterilization and deemphasized condom and pill contraceptives since 1978. However, the recent service statistics has revealed that the acceptance rate of female sterilization has steadly declined since 1979. Thus, the purpose of this analysis is to review the current government policy on contraceptive distribution with emphasis of female sterilization by estimating the prospect of sterilization acceptablilty. According to the Fifth Five-Year Plan for Family Planning Program(1982-1986) the annual average target of sterilization was set up to secure 230, 000 acceptors by the government sector during the period. If the sterilization target is to be met as planned, about 80 percent of exposed women aged 30-44 will be remained as sterilized women in 1985. This means the the high acceptance rate of sterilization shown in the past years can not be expected, unless the acceptors' age of sterilization is drastically lowered below 30 years. Accordingly, the current policy on contraceptive distribution with emphasis on sterilization should be gradually changed to encourage target population to use contraceptives for birth spacing by increasing access to such contraceptives as IUDs, pills, and condoms, and to improve continuation rates through better program management system including target setting, acceptors' follow-up, supervision, and evaluation system.
