Objectives: This study aims to establish a Korean medicine doctor's range of services in the dementia relief primary care system based on the previously developed dementia clinical practice guidelines (CPGs). Developing a dementia relief primary care Clinical Pathway (CP) can aid clinically when the Korean medicine primary care doctor conducts treatment. Methods: We analyzed Dementia Korean Medicine Primary Care Model Data and then applied CP Methodology to develop the configuration of the Korean Medicine Primary Care Model. For patients with Alzheimer's dementia (AD), vascular dementia (VD), and mild cognitive impairment (MCI), the Korean Medicine Primary Care Model focuses on improving cognitive function, everyday living abilities and easing symptoms through interventions described in CPGs. The contents of the draft model later include references to already-existing CPs. Results: The study sites were chosen as Korean medical clinics connected to primary care physicians in the dementia-friendly model. The CP used a time task matrix version to arrange the clinical chronology, which included all examinations, diagnoses, and treatment procedures, from the initial appointment to follow-ups and the end of therapy. Conclusions: It anticipates that Korean primary care doctors familiar with dementia can use the offered therapies for the first time by creating the dementia Korean medicine primary care model in this study. This is expected to maximize the range of medical services provided by Korean medicine and improve the standard of medical treatment.

The effect of primary solidification phase on the solidification cracking sensitivity, corrosion resistance and toughness at cryogenic temperature was investigated for the austenitic stainless steel welds. The conclusions were summarized as follows; 1. Soldification crack sensitivity of austenitic stainless steel welds depends on the primary solidification mode. 2. Austenitic stainless steels were very susceptible to solidification cracking in case of solidification as primary ${\gamma}$ and immune when solidified as primary $\delta$. 3. When the ratio of Creq/Nieq is in the range of 1.46 to 1.55, the most resistance against solidification cracking was obtained. These results agreed well with the relationship between primary solidification mode, corrosion resistance and toughness at cryogenic temperature. 4. Optimum toughness, corrosion and solidification cracking resistance can be obtained when alloys having chemical compositions described above and solidifies as primary $\delta$ containing no ferrite at room temperature.

Let R be a commutative ring with $1{\neq}0$. In this paper, we introduce the concept of 2-absorbing primary ideal which is a generalization of primary ideal. A proper ideal I of R is called a 2-absorbing primary ideal of R if whenever $a,b,c{\in}R$ and $abc{\in}I$, then $ab{\in}I$ or $ac{\in}\sqrt{I}$ or $bc{\in}\sqrt{I}$. A number of results concerning 2-absorbing primary ideals and examples of 2-absorbing primary ideals are given.

One of the most important tasks of ocean color observations is to determine the distribution of phytoplankton primary production. A variety of bio-optical algorithms have been developed estimate primary production from these parameters. In this communication, we investigated the possibility of using a novel universal approximator-support vector machines (SVMs)-as the nonlinear transfer function between oceanic primary production and the information that can be directly retrieved from satellite data. The VGPM (Vertically Generalized Production Model) dataset was used to evaluate the proposed approach. The PPARR2 (Primary Production Algorithm Round Robin 2) dataset was used to further compare the precision between the VGPM model and the SVM model. Using this SVM model to calculate the global ocean primary production, the result is 45.5 PgC $yr^{-1}$, which is a little higher than the VGPM result.

This research studied the social-emotional competence of children whose primary caregiver was a single-mother or single-father alone compared with children living with a single-parent but the primary caregiver was a non-parent (e.g. a grandparent). Subjects were 208 children (105 boys, 103 girls) from 10 elementary schools in 3 metropolitan cities. Instruments were the Adaptive Behavior Checklist constructed by the researcher, Self-esteem Inventory (Kim, 1987) and Emotional Competence Scale (Kim, 1998). Results showed that children in single-mother families were more social-emotionally competent than children in single-father families. Children whose primary caregivers were non-parents had higher self-esteem than children whose primary caregivers were single parents alone. There were interaction effects of caregiver variables on children's peer relationships and awareness/expression of their own emotion.

Rheocasting of AZ91D magnesium alloys yielded the microstructure consisted of the spherical primary particles in the matrix which is different from conventional casting. Rheocast ingots were produced under various processing conditions using batch type rheocaster. Morphology of primary particles was changed from rosette-shape to spherical shape with increasing stirring rate$(V_s)$ and decreasing isothermal stirring temperature$(T_s)$. With increasing $V_s$, more effective shearing between the particles occurred rather than the agglomeration and clustering, so the primary particle size decreased. But with decreasing $T_s$, primary particle size increased mainly due to sintering and partially Ostwald ripening. The sphericity of primary particles increased with increasing $V_s$ and decreasing $T_s$ due to enhanced abrasion among the primary particles. The uniformity of primary particle size increased with increasing Vs and $T_s$.

The purpose of this study was to investigate whether there are any differences among kindergarten teachers', primary school teachers', and children's mothers's perceptions-belief, knowledge, practice-about the educational articulation between kindergarten and primary school. The results of this study were as follows; First, there were differences among kindergarten teachers, primary school teachers, and mothers about the belief of articulation content. Second, in the knowledge of educational articulation, kindergarten teachers's understandings of the counterpart's curriculum were higher than that of primary school teachers's. Third, in the practice of educational articulation, kindergarten teachers and mothers were focused language and mathematics learning for educational articulation. But primary school teachers were focused school adjustment.

Multiple primary cancer is defined as the discrete primary cancers in an individual originating in different sites or tissues. Billroth, in 1869, first reported the occurrence of different primary malignant cancers in the same patient. Because early diagnosis and treatment are key to good survival and cure rates, clinicians should be more aware of the possibility of multiple primary cancers in an individual patient with malignant tumor. The authors recently experienced a case of fifth primary cancer, their sites of origin were lung, glottis, lymph node, supraglottis, common bile duct. We report this case with a brief review of literatures.

Purpose: This study developed a shelter for dementia programs based on primary health care posts; and examined its effectiveness in rural older adults. Methods: This study used a case report provided by a primary healthcare post in Jeonnam, Korea, in 2023. A single group pre-test post-test design was used; for three months, and 10 older adults participated in the shelter for dementia programs based on the primary health care post. The effectiveness of the intervention was measured immediately after entering the shelter for dementia programs. Results: There were significant differences between the pre-test and post-test on the cognitive impairment screening test (p=.005). Conclusion: The shelter for dementia programs based on primary health care posts was effective in improving cognitive impairments of rural older adults.
