The purpose of this study is to propose an effective PR plan for government policies in order to make the people aware of the importance of the fertility rate by seeking strategies to counter the low fertility rate. Focus group interviews were conducted with 6 experts with high expertise in government policy advertising and public relations among advertising and public relations academics and practitioners. It was found that low fertility PR strategy raised the problems of integrated public relations and budgeting. PR message strategy was lacked a creative approach suitable for the target, and the media strategy did not reflect the characteristics of the younger generation. Based on these research results, an improvement plan for government PR to counter the low fertility was proposed, and it is expected that it will be used for policy making in the future.

Familial hypercholesterolemia (FH) is a genetic disease that is not well known or diagnosed in Korea. This disease is associated with persistently high levels of low-density lipoprotein cholesterol (LDL-C), which increase the risk of coronary artery disease at a young age. Therefore, early diagnosis and treatment are important; however, there are no global consensus diagnostic criteria. In Korea, the Dutch Lipid Clinic Network diagnostic criteria, and the Simon Broome diagnostic criteria were used for diagnosis of FH according to the agreement announced at the Korean Society of Lipid and Atherosclerosis (KSoLA) in 2022. Recently, the absence of coronary artery calcification has been considered a good prognostic factor, even among patients with very high LDL-C levels who are considered to be at high risk for atherosclerotic cardiovascular disease. We describe throughout this paper the diagnosis and treatment of FH in a young male without coronary artery calcification.

Bilateral femoral neck stress fractures have been rarely reported. When diagnosed, they are usually limited to athletes or military personnel. A 35-year-old man, previously healthy, visited the emergency department for right inguinal pain. On physical examination, no external wound, tenderness or limitation of motion were found in either lower extremity. Plain radiography showed normal findings but an magnetic resonance image showed a linear fracture in the femoral neck. In this case, bilateral femoral neck stress fractures were found in a young non-athlete adult with no prior medical history of related injuries. Surgery is generally not performed for stress fractures but considering the patient's early mobilization and the need for quick reintegration into society, surgery was done in this case.

Purpose : Hepatitis A viral infections have been continued after re-emerging since mid 1990s in Korea. The incidence of this disease has been increased in young adults younger than 30 years of age since 2000. This study was performed to evaluate the prevalence of antibody to hepatitis A in Korea(two regions; Incheon and Changwon) in 2005, and was compared with the results of similar studies in mid 1990s. Methods : The study was conducted from January 2005 to June 2005, and consisted of 1,301 enrolled subjects, neonates to 50 years old, living in Incheon and Changwon in Korea. All sera were frozen and stored at $-70^{\circ}C$ until assayed. Anti-HAV IgG antibodies were measured by microparticle enzyme immunoassay(HAVAB, Abbott Lab., IL, USA). Results : The prevalence of anti-HAV IgG was 61.1% in infants younger than 1 year old, 30.5% in 1~5 years, 14.6% in 6~10 years, 1.7% in 11~15 years, 6.5% in 16~20 years, 36.6%in 21~30 years, 77.5% in 31~40 years, and 99.8% in 41~50 years. Statistical differences were not found between male and female, but there was statistical difference in 6~10 years old age group between the two areas. Conclusion : Our study indicate that the prevalence of antihepatitis A virus antibody has shifted from children to old adolescents and young adults. This result suggests that the risk of sudden outbreaks or increasing incidence of hepatitis A viral infections in young adults may be expected in our society. The preventive strategies of hepatitis A including vaccination should be prepared.

Purpose : We investigated the change of spherical and comma aberrations after wearing aspheric soft contact lens (ASCL) in young myopes. Methods : Fifty young myopes ($23.15{\pm}1.70years$, spherical equivalent: $-2.90{\pm}1.75D$) were recruited and refractive errors were corrected using ASCL (Biotrue, Bausch+Lomb, USA). High order aberrations were measured in the 4 mm pupil size using the wavefront analyze and pupil sizes were measured with a pupillometer at the modes of scotopic condition (light off) at 3.5 m in the 100 lx illuminance condition. Results : Spherical aberrations and coma aberration of the 20s myopes were $0.026{\pm}0.031{\mu}m$ and $0.078{\pm}0.039{\mu}m$ respectively, and $0.019{\pm}0.026{\mu}m$ and $0.082{\pm}0.038{\mu}m$ after ASCL wear that spherical aberration was decreased and coma aberration was increased. However, spherical aberration was decreased in the 68% of the subject have positive spherical aberration, and increased in the 11% of the subject have negative spherical aberration. Coma aberration was increased in the 53% of the subject, did not change in the 19% of the subjects, and decreased in the 28% of the subject. Spherical aberration was not different with the refractive errors in low and moderate myopies, however, coma aberrations was higher in the higher myopes. Conclusion : In a scotopic condition without accommodation stimuli, spherical aberration is decreased after wearing ASCL, however in the subject have negative spherical aberration spherical aberration could be increased, and which is thought to be the influence of contact lens design and pupil size.

The Java language has been established as one of the most widely used language due to its object-oriented programming, safety and flexibility and the garbage collection of the virtual machine has relieved programmers of many difficulties related to the memory management. In the embedded environment, Java is also prevalent, the virtual machine and garbage collector that takes into account the embedded environment is required. In this paper we manage the heap memory area by dividing into young generation and old generation, and we propose a garbage collector in which appropriate techniques are applied to each generation to utilize the different characteristics of each generation. Also, we propose the write barrier technique and double filtering technique for efficient garbage recognition, and double check method for determining and reclaiming the garbage with cyclic structure. The proposed method satisfies the embedded environment's requirements of fast object allocation, real time property, recollection of all the garbage, elimination of fragmentations and high locality.

Giant cell tumor of the small bones of the hands and feet is rare. Giant cell tumors in these locations develop at young age, are more commonly multifocal, and show the higher risk of recurrence than those at the end of the long bone. It should be differentiated from the other lesions of the hands, such as giant cell reparative granuloma, aneurysmal bone cyst and enchondroma. We experienced a case of giant cell tumor in the proximal phalanx of the left hand with swelling and pain. Curettage and bone graft were performed. Histologically large number of giant cells were distributed diffusely in the highly cellular stroma containing sheets of mononuclear cells. Secondary aneurysmal bone cyst and hemorrhage were associated.

The present study aimed to investigate the relationships among consumers' personality trait, brand tribalism, and brand commitment through brand trust and perceived switching cost. Data were collected from a convenience sample of three-hundred and ninety-four undergraduate students at a large Korean university. The participants consisted of 54.1% female (N = 213) and 45.9% male (N = 181). The results indicated that extraversion, conscientiousness, and emotional stability traits are directly related to brand tribalism. Also, brand commitment was directly associated with brand tribalism, brand trust, and perceived switching cost. In particular, our results showed the relationship between brand tribalism and brand commitment was mediated by brand trust, but not perceived switching cost. Therefore, our findings suggest that strong emotional connection of brand tribes may increase perceived switching costs and, consequently, affect brand commitment.
